Resolving Noise Disposal of Reducer

The noise of the reducer indicates that there must be something wrong with the reducer. At the same time, the noise of the reducer will affect the operation of the reducer. For this reason, our company will elaborate on how to solve the noise problem of reducer for you in detail. Finally, we will also elaborate on the details of gear reducer installation. The installation of counter-moment bracket, the relationship between reducer and worker, and the connection between reducer and worker are three main aspects. Detailed elaboration below. First, the noise of reducer is mainly caused by friction, vibration and collision of transmission gears. How to effectively reduce and reduce noise and make the mixer more in line with environmental protection requirements is also a key research topic at home and abroad. Reducing the noise of gear transmission in reducer operation has become an important research topic in the industry. Many scholars regard the change of meshing stiffness of gear

Installation Matters of Reducer Bearing

The bearing of the upper part of the reducer is immersed in oil or forced lubrication. In order to prevent oil leakage in the extension direction of the lower axle, the combined seal is adopted. In the current selected reducer, no forced lubrication is required, and oil immersion lubrication is adopted. This requires a filling tank on the upper part of the reducer, and the filling tank should have a high oil level. Out of the upper bearing position of the reducer to meet the needs of bearing oil-immersed lubrication. It is worth noting that the axial and radial forces on the output shaft of the reducer are limited because the bearings on the output shaft of the reducer are installed in accordance with the conventional method. When there is a large external force, the structure of reducer should be redesigned to select bearings according to the axial and radial forces provided. However, the overhead passenger's steel rope driving wheel suffers a large torque. When directly connec

Committed to energy saving and emission reduction to improve work efficiency when using reducer

When we use the reducer , we will encounter the problem of oil change, because the machine is not always a long-term work, it also needs rest and energy supplement, just like changing oil for the reducer, it can work more efficiently, but it also needs to pay attention to oil change, when to change it, this is also the case. It is important to note that, generally speaking, the reducer is fuel-efficient enough, it will take a long time, but note that this is also useful for use. In recent years, with the scarcity of various kinds of energy, enterprises gradually find that this production mode is not suitable for sustainable development policies, but also will not have too much development prospects. Then they seek other production modes. The reducer industry has been committed to building energy-saving and emission reduction production mode, which has gradually become relatively mature. Enterprise system. Large-scale reducer equipment will consume more materials and increase power co

The output shaft of reducer is also broken or bent.

The output shaft of the reducer is also broken or bent, the reason is the same as that of the drive motor. But the output of the reducer is the product of the drive motor output and the deceleration ratio. Compared with the motor, the output force of the reducer is larger, so the output shaft of the reducer is easier to be broken. Therefore, when users use the reducer, the assurance of the concentricity of the output assembly of the reducer should also be paid great attention. Secondly, in the process of acceleration and deceleration, if the instantaneous torque of the output shaft of the reducer exceeds twice its rated output torque, and the acceleration and deceleration are too frequent, the shaft of the reducer will eventually be broken. Considering that this situation occurs less frequently, we will not introduce it further here. If the concentricity error of the reducer is large, the radial force will increase the temperature of the motor output shaft, and the metal structure w

Fatigue damage easily occurs when the diameter of input shaft of reducer is smaller.

The reducer is in the form of vertical axle, the first input axle is bevel gear axle worm gear reducer , and fatigue damage occurs due to serious stress concentration at the shoulder of transition axle at the bearing support of bevel gear; the reducer is a hard tooth surface reducer, and the diameter of the input axle of the reducer is smaller, although the calculation strength is passed, because the axle itself is very thin. At the same time, the stress concentration is serious and fatigue failure occurs at the change of shaft diameter, and the heat treatment quality of the input shaft of worm gear reducer is not up to standard. Attention should be paid to the daily maintenance of the reducer, not only use, not maintain, this is the big taboo of the reducer, how good the equipment, not maintain, his life should be reduced by at least one third. So the daily maintenance is particularly important. The daily maintenance of reducer includes: the use and replacement of lubricating oil, t

Differences in Design and Selection Methods of Universal Reducer and Special Reducer

The biggest difference between the general reducer and the special reducer is that the former is suitable for all industries, but the deceleration can only be designed according to a specific working condition. Therefore, when selecting the reducer, users need to consider different correction coefficients according to their requirements. The factory should select the motor power according to the actual selection (not the amount of the reducer). The latter is designed according to the user's special conditions, and the coefficients considered in the design are generally considered. The method is relatively simple as long as the power used is less than or equal to the rated power of the reducer. The general reducer often has to limit the maximum radial load allowed on the middle part of the extension of the input shaft and the output shaft. It should be checked. When exceeding the limit, the requirement of increasing the diameter of the shaft and the bearing should be put forward

Axle Breakage in Reducer Output

In addition to the concentricity of the reducer output assembly is not good, resulting in the breakage of the reducer shaft, if the output shaft of the reducer is broken, there are no more than the following reasons. First of all, the incorrect selection results in insufficient output of the gearbox. Some users mistakenly believe that as long as the rated output torque of the selected reducer meets the working requirements, in fact, otherwise, first, the rated output torque of the distribution motor multiplied by the deceleration ratio, the value obtained is in principle smaller than the rated output torque of the similar reducer provided by the product sample, and second, it should also be considered. The overload capacity of the driving motor and the maximum working torque required in practice. In theory, the maximum working torque required by the user. Must be less than 2 times the rated output torque of the reducer. Especially in some applications, this criterion must be stric

Correct Installation of Reducer

Correct installation, use and maintenance of reducer is an important link to ensure the normal operation of mechanical equipment. Therefore, when you install planetary reducer, you must strictly follow the following installation and use related matters, and carefully assemble and use. The first step is to confirm whether the motor and reducer are in good condition before installation, and strictly check whether the dimensions of the parts connected by the motor and reducer match. Here are the dimensions and tolerances of the positioning bump, input shaft and reducer groove of the motor. The second step is to screw down the screw on the outer dust-proof hole of the reducer flange, adjust the PCS clamping ring to align the side hole with the dust-proof hole, and insert the inner hexagon to tighten. After that, remove the motor shaft key. The third step is to connect the motor with the reducer naturally. When connecting, it is necessary to ensure that the concentricity of the out

How to Choose Reducer

The selection of general reducer includes the steps of putting forward original conditions, selecting types and determining specifications. In contrast, the selection of type is relatively simple, and the key to the correct and reasonable selection of specifications of general reducer is to accurately provide the working conditions of reducer and master the design, manufacture and use characteristics of reducer. Specification selection should satisfy the conditions of strength, thermal balance and radial load bearing at the axle extension part. 1. Select specifications according to mechanical power or torque (strength check) The biggest difference between the general reducer and the special reducer is that the former is suitable for all industries, but the deceleration can only be designed according to a specific working condition. Therefore, when selecting the reducer, users need to consider different correction coefficients according to their requirements. The factory should se

What are the reasons for the series axle of reducer?

People who often deal with machinery know that reducer is an essential auxiliary equipment in some machinery, because some machinery will run at a dangerous speed quickly, so it is necessary to use reducer to balance its movement speed. However, in the process of using reducer, the reasons for the series axles of reducer are mastered from the following three points. 1. Series of axes occur because the broken teeth make the input shaft lose its axial restraint, and the driven gears on the middle axle are not tightened tightly with the axle. In actual transmission, because of the insufficient interference between the driven gear and the intermediate shaft, the driven gear produces axial series motion relative to the intermediate shaft, which makes the input shaft produce axial series motion. Therefore, insufficient interference is the main reason for the series axle of reducer. In addition, the steering of the reducer has a certain impact on the series axle. 2. Gear processing devia

Attention should be paid to these three points when installing planetary reducer correctly

The problem of how to install planetary reducer correctly has been introduced to you in the previous information, but some users will inevitably encounter some problems in the process of installation. In order to solve your questions, the general reducer summarizes three points of attention for you to install planetary reducer correctly: Firstly, before installing planetary reducer, we should confirm whether the motor and reducer are damaged, check whether the dimensions of the parts connected with the reducer match, especially check whether the motor bump and stop match the reserved tolerance of the reducer. If the motor bump is too small, it will cause the motor and reducer to be different from each other, which is easy to make. The motor shaft is twisted and bent. Secondly, when connecting the motor to the reducer, if the shaft is connected, the motor shaft is directly extended into the coupling, and then the screw is locked on the side. If the direct connection type is used, t

The difference between ordinary reducer and planetary reducer

Planetary reducer is generally used for transmission equipment with low speed and high torque. The reducer's function is to reduce the speed and increase the output torque. The output torque ratio is multiplied by the click output speed ratio, but attention should be paid to not exceed the rated output torque of the reducer. The planetary reducer also reduces the inertia of the load. Servo reducer has the advantages of compact structure, small backhaul clearance, high accuracy, long service life and large rated output torque. However, the main feature of harmonic reducer with slightly expensive price is that it uses flexible components to control elastic deformation to drive motion and power. It has small volume and high precision, but its disadvantage is that flexible wheels have limited life. Shock resistance, rigidity is worse than metal parts. The input speed should not be too high. Common types of reducers are worm gear and worm gear reducers, whose main characteristics ar

Final Heat Treatment of Reducer Gears

In the operation of the reducer , there is also a need for professional personnel to take care of, so as to ensure that equipment in the use of the process can get the best help. I believe that with these guarantees, the efficiency of the whole work can be significantly improved. The final heat treatment of gear reducer adopts high frequency quenching which makes the deformation of the part smaller. The surface obtained after high frequency quenching has high strength, hardness, wear resistance and fatigue limit, while the core still maintains enough plasticity and toughness. In order to reduce the deformation of reducer, low quenching temperature and short heating time, uniform heating and slow cooling should be adopted for high frequency quenching of tooth surface.

The output speed of the reducer is smaller than the theoretical value.

If it is rated load, the output speed of the reducer is smaller than the theoretical value. 1. If the reducer is separate, the speed ratio of the reducer is the transmission multiple of the internal gear of the reducer. For example, in a gear reducer, the product of the number of teeth of all large gears divided by the number of teeth of all pinions is the speed ratio. 2. If the motor and the decelerator are integrated, such as the miniature deceleration motor, the output of the motor is toothed and meshes with the gears on the decelerator, then the deceleration ratio is: the product of the number of teeth of all driven gears divided by the number of teeth of all active gears is the speed ratio. 3. Drive Ratio Motor Input Speed Divided by Retarder Output Speed = Drive Ratio Portal:https://www.zwgearbox.com/

Method/step First, attention should be paid to the construction of the installation site of the reducer. The installation of reducer requires smooth ground and good ventilation conditions. It is important to know that the installation site has a great influence on the use of reducer in the future. Second, we should pay attention to the daily maintenance of the reducer, not only use, not maintain, this is the big taboo of the reducer, how good the equipment, not maintain, his life will also be reduced by at least one third. So the daily maintenance is particularly important. The daily maintenance of reducer includes: the use and replacement of lubricating oil,

How to prolong the life of gear reducer

Gear reducer is an important part of transmission equipment. It plays a vital role in improving the load-carrying capacity and service life of gear reducer. After selecting the type of reducer, lubricating oil (gear oil or oil) is added and installed on the worktable. The height gauge is used to measure and adjust the test instruments and test instruments. The center height of the reducer. After they are at the same central height, they are fixed by bolts and gaskets, and run-in test is carried out with small loads. After running for a period of time, the lubricant is poured out to check whether there is metal powder in the oil, and then cleaned again. Then the lubricant is added to restart the fall run-in until no metal powder is found. Finally, the lubricating oil seal was re-added and the load was increased to carry out the test. For the first time use of gear reducer, it is indispensable to carry out trial operation first. Many users often neglect this preliminary work, which ev

Knowledge Points to be Determined in Selecting Planetary Gear Reducer

Planetary gear reducer is very popular in the market. Many enterprises recognize this kind of planetary gear reducer. It not only has high recognition, but also has a good reputation in the hands of consumers. Planetary gear reducer is the main type of reducer matching servo motor. What factors should be determined when selecting it? Details are as follows: When choosing planetary gear reducer, the first step is to determine the deceleration ratio of the reducer. If the standard reducer does not have the deceleration ratio you need, please choose the approaching or customized reducer from our company. The single-stage deceleration of planetary reducer is the smallest and the maximum is not more than 10. The common deceleration ratio is 3/4/5/6/8/10, and the series of reducer is not more than 3. However, some customized reducers with large deceleration ratio have four-stage deceleration. Compared with other reducers, planetary reducer has the characteristics of high rigidity, high pr

Advantages of Planetary Gear Reducer and Common Cylindrical Gear Reducer

Compared with cylindrical gear reducer, planetary gear reducer has many unique advantages. Its most remarkable feature is that it can distribute power when transmitting power; at the same time, its input axis and output axis are coaxial, that is, the output axis and input axis are located on the same main axis. Therefore, planetary gear reducer transmission has been used to replace the ordinary gear transmission, and as a kind of accelerator and transmission device in various mechanical transmission systems. The main characteristics of planetary gear reducer transmission are as follows. 1. Smooth motion, strong shock and vibration resistance? Because several planetary wheels with the same structure are used, they are evenly distributed around the center wheel, thus balancing the sexual forces between the planetary wheel and the runner arm. At the same time, coaxial reducer also increases the number of teeth involved in meshing, so planetary gear transmission has smooth movement, s

Reducer low noise era has arrived

Noise, whether to human body, equipment or building structure, will cause great harm. The advent of the era of low-noise reducers will end all this. Noise can affect people's sleep, its physiological function is affected to a certain extent, will make hearing decline, affect other people's system. Normal noise has little effect on buildings, but when the noise level exceeds 140 dB, it begins to destroy light buildings. For example, when a supersonic aircraft passes at low altitude, sudden changes in pressure and density occur in the front and rear of the aircraft. A N-shaped shock wave is formed after reflection from the ground. When it reaches the ground, it sounds like explosion. This special noise is called boom. Under the effect of the roar, buildings will be damaged to varying degrees, such as damage to doors and windows, broken glass, wall cracking, plastering and shaking, chimney collapse and other phenomena. Because of the slow attenuation of the bomb, it spreads far a

Will the temperature of gear reducer be affected?

Gear reducer is used in every field of our life. It is generally used in low speed and high torque transmission equipment. With the development of the reducer industry, more and more industries use the reducer. Whether the reducer will be affected by the temperature when it works properly is explained below. 1. Limit operating temperature of insulating material refers to the hottest temperature in winding insulation of gear reducer during its design life expectancy. If the operating temperature exceeds the limit working temperature of the material for a long time, the aging of the insulation will be aggravated and the service life will be greatly shortened. Therefore, in the operation of gear reducer, temperature is one of the main factors of life. 2. Temperature rise is the temperature difference between the gear reducer and the environment, which is caused by the heat of the gear reducer. Temperature rise is an important index in the design and operation of gear reducer, whi
