Heat treatment method of planetary reducer

Choosing good material of planetary reducer is conducive to improving the bearing capacity and service life of gear reducer. In view of the structural characteristics of precision reducer and the load characteristics of gears, hard tooth face gears should be widely used. There are many heat treatment methods to obtain hard face gear. For example, surface quenching, whole quenching, carburizing quenching and nitriding should be selected according to the characteristics of gear reducer. 1. Surface hardening The common surface quenching methods are high frequency quenching (for small size gears) and flame quenching (for large size gears). When the hardened layer of surface hardening includes the bottom of the tooth root, the effect is the best. The hardness of tooth surface can reach 45-55HRC. 2. Nitriding The application of nitriding can ensure that the gear can achieve high hardness and wear resistance under the condition of minimum deformation. After heat treatment,

What should we pay attention to when using circular arc gear reducer

In order to improve the operation efficiency, the worm gears of arc gear reducer are made of non-ferrous metals, and the worm gears are mostly made of hard steel. Therefore, in the running process of sliding friction transmission, the worm gear reducer will generate more heat and increase the temperature of the reducer. High temperature will lead to the difference in coordination of various parts in the reducer due to the different thermal expansion coefficients, resulting in the clearance of the mating surface. The lubricants and other oils used in the reducer will also dilute or deteriorate under the action of high temperature, resulting in leakage or lubrication failure. The way to prevent the temperature rise of worm gear reducer is to rationally match the material of worm wheel and worm, to avoid excessive friction, and to note at the same time. Another direct way to reduce the temperature of the reducer is to install a cooling device or to reduce the temperature of the working e

How to Reduce Noise of Worm Gear and Worm Reducer

As everyone in the reducer industry knows, the noise of the reducer , especially the worm gear reducer, is a headache for many reducer manufacturers. Reducing noise and ensuring non-chaotic operation is the first prerequisite for the quality of reducer. For how to achieve this goal, many scholars at home and abroad regard the change of meshing stiffness of gear teeth as the main factors of dynamic load, vibration and noise of gears. The method of modification is used to minimize the fluctuation of dynamic load and velocity in order to reduce noise. This method has been proved to be effective in practice. However, in this way, the process needs to be modified. After years of research, a gear design method is proposed to minimize the meshing impact speed by optimizing gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle and central distance. The ratio of meshing impact speed to meshing impact speed is in a certain range. The gear design me

The assembly accuracy has a direct influence on the meshing condition and load-carrying capacity of gears.

The influence of lubrication mode on the efficiency of reducer The lubrication mode of gears is determined by the pitch speed of gears. Oil bath lubrication can be used when the pitch speed is not very high. The loss of stirring oil in oil bath lubrication is related to tooth width, gear circumference speed, oil immersion depth, oil viscosity and other factors. Generally speaking, the wider the gear, the deeper the oil immersion, the higher the oil viscosity, and the higher the gear speed, the greater the oil stirring loss. When the throttle speed is high, oil injection lubrication should be used as far as possible. The main loss of oil injection lubrication is the energy consumed by accelerating oil supply. It is related to the amount of oil supplied, the oil storage gap between meshing teeth and the oil viscosity. The curves of oil mixing loss with gear pitch velocity are given under different viscosity, top clearance and oil supply under oil injection lubrication. The oil visco

Wide application of planetary reducer

Planetary reducer is a kind of reducer device with solar wheel, planetary wheel and external gear as the main transmission structure. Planetary reducer has stable operation and powerful performance. Its input speed can reach 18000 rpm and output torque can be maintained at 2000 Nm. It is a common reducer product in industrial production. Compared with other reducers, planetary reducers have better rigidity, accuracy, higher torque and volume ratio, especially in transmission efficiency, and the single-stage transmission efficiency of planetary reducers can reach more than 97%. In addition, planetary reducer has the advantage of lifelong maintenance-free, which makes it easier and more convenient to use. Because of these advantages, planetary reducer is more suitable for limited working space and high torque requirements, that is, small space and high torque conditions, because most planetary reducers are installed in stepping motors and servo motors to reduce speed and impro

Eight Points for Attention in Installation and Trial Operation of Reducer

Reducer is a common power transmission mechanism, which is used in various mechanical transmission systems. Installation and Use of Reducer. The operation effect of the gear reducer should conform to the technical specifications and standards. Attention should be paid to the following points in the installation and trial operation of reducer. 1. When installing reducer, special attention should be paid to the axis of transmission center. In the alignment, the error of alignment should not exceed the compensation of the coupling used in the reducer. After the gear reducer is aligned according to the requirements, it can obtain more ideal transmission effect and longer service life. 2.When installing transmission parts on the output shaft of the reducer, attention must be paid to the soft operation. It is forbidden to use tools such as hammers to install roughly. It is better to install them by means of assembly fixture and internal thread of the end shaft to screw.

Early pitting condition of reducer

How to solve the early pitting corrosion of reducer . Pitting corrosion is definitely related to lubricating oil, and it is also closely related to the material of reducer. Usual use process will have a certain deal with specifications. Another point is that the local overload is caused by the poor contact of gears. The local overload of gears makes the actual contact stress greatly exceed the allowable contact stress of gear materials. Some gears can not reach full tooth length contact or only contact at one end of the tooth, even diagonal contact. I. The Impact of Materials and Processing Specifications Correct selection of gear material, matching of load and hardness of heat treatment are also the causes of early pitting corrosion. II. THE EFFECT OF LUBRICATING OIL Because of the unreasonable lubrication of gear transmission and the unsuitable choice of lubricant, the early pitting corrosion is also affected. Ways to prevent early pitting corrosion of reducer gears:

When using the reducer in the work, we need to ensure that we can get a very good result of using the equipment. If we can't deal with these things in a very comprehensive way when we are working, it will definitely directly affect our working conditions. So, how can we make the best use of these devices? If you want to get a very good effect when using the reducer, you need to have a very comprehensive understanding of the equipment before using it. As long as we can have a comprehensive understanding of equipment, postage and shipping, we can know more clearly what we need to pay attention to when using equipment. Many people do not handle these tasks well in their entertainment, which affects their work efficiency. When using the reducer, it also needs to have a very comprehensive maintenance of the equipment, so as to ensure that the process of using the equipment can obtain very good results.

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, the inspection of the installation foundation, seals, transmission shafts and other normal, the maintenance of important parts such as shell debonding. Third, attention should be paid to the maintenance of the reducer during its downtime. Portal:https://www.zwgearbox.com/

Reduction motor is widely used. The working principle of the gear box of the deceleration motor is that the gear box is used to change the speed. The deceleration motor reducer or the deceleration motor mostly changes the speed through gears. The small edition will analyze the relevant knowledge of the deceleration motor for you. Firstly, deceleration motor is often referred to as gearbox. Second: Change the direction of transmission, for example, we can use two sector gears to transfer force vertically to another rotating shaft. Thirdly, change the rotating moment. Under the same power condition, the faster the speed of the gear, the smaller the moment the shaft is subjected to, and vice versa. Fourth: Clutch function: We can separate the engine from the load by separating two original meshing gears, such as brake clutch. Fifth: Distribution of power. For example, we can use an engine to drive multiple slave shafts through the gearbox spindle, thus realizing the

Gear modulus in gear reducer is the knowledge that every operator should know.

For gear reducer motor , one of its key knowledge points is the gear modulus in gear reducer, which is still relatively vague for some users, especially for some new users. Today, we will focus on this knowledge for you to sort out and analyze, as follows: The main problem of gear modulus in gear reducer is that if the higher the modulus gear teeth are, the thicker the modulus is. The modulus refers to the ratio of teeth pitch t to circumference PI (m=t/pi) between the two adjacent teeth on the same side of the tooth profile in millimeters. Modulus is a basic parameter of modular gear system. The bigger the modulus is. If the number of gear teeth is constant, the larger the radial dimension of the wheel is. For gears with non-straight teeth, modulus series standards are formulated according to the requirements of design, manufacture and inspection. Modulus has the difference between normal modulus Mn end-face modulus MS and axial modulus mx. They are all based on the ratio of the

1. Reduction Motors should always clean up oil, dust, keep clean, in order to facilitate heat dissipation. 2. Oil seal damage should be replaced in time. 3. Lubricating oil should be replaced regularly: when the new machine is in first use, it must be replaced after 7 to 15 days of operation. In the future, it can be replaced once in 3 to 6 months according to the condition of the machine. It should be noted that when changing oil, the power supply should be blocked to ensure safety. When looking at the oil, if it is found that the lubricant is obviously turbid, please replace it as soon as possible. 4. In the work, when it is found that the temperature of oil exceeds 80 C or the temperature of oil pool exceeds 100 C and abnormal noise occurs, it is necessary to stop using, check the reasons, remove the troubles and replace the lubricant before continuing to work. 5. It should be noted that lubricants of different qualities can not be mixed. 6. The operation and

Micro DC deceleration motor is mainly used in the joints and heads of robots, which need to move. It is a very important component, so it is necessary to improve the technology content of micro DC deceleration motor. Robot action is relative to imitating human action, we know that human action can be extremely diverse, waving, shaking hands, walking, running, jumping, and other gestures, are human habitual actions. However, although modern intelligent robots can imitate some human actions, they are relatively rigid or slow. In the future, it will be possible for robots to imitate human joints and artificial muscles more flexibly, to imitate all human actions and even to make them more tangible. It is also possible to make some actions that ordinary people are difficult to do, such as flat somersault, handstand and so on. In the field of automation equipment: the use of miniature DC deceleration motor improves production efficiency, product quality, labor intensity, occupatio

How to reduce noise in the design of gear reducer?

图片
The influence of gear reducer manufacturing accuracy on noise mainly includes three factors: accumulated pitch error, pitch deviation, radial runout and total tooth profile deviation. What are the noise reduction methods of gear reducer?  1. Coefficient of gear overlap and displacement? The stability between gears is proportional to the coefficient of gear meshing overlap. With the increase of the coefficient of gear meshing overlap, the noise of gears will be smaller. This is the basic principle of adjusting the coefficient of gear overlap. In the process of adjustment and design, designers should first choose helical gears to drive, increase the meshing section and stiffness of gears, and improve the noise of gears. Control. To a great extent, the modification coefficient of gears will restrict the strength of gears, improve the matching effect of gears, and affect the meshing noise between gears.  2. Improvement methods of gear modulus and tooth number design? There is a

Processing Method for Deviation of Gear Reducer?

When using some plane double enveloping gear reducer equipment, we often encounter some gear deviation phenomena. Today we will talk about the single gear pitch deviation: on the end plane of the screw elevator, on a circle close to the middle of the tooth, which is concentric with the axes of the gear reducer, the algebraic difference between the actual pitch and the theoretical pitch. Cumulative deviation of gear reducer pitch: the algebraic difference between the actual and theoretical arc lengths of any K pitches. In theory, it is equal to the algebraic sum of each single pitch deviation of the K pitches. The pitch number K is given by the design. Total accumulated pitch deviation: The maximum accumulated pitch deviation in any arc section of the same side tooth surface of gear reducer (K=1 to K=Zc, Zc is the number of teeth of cycloidal gears). It represents the total amplitude of the cumulative deviation curve of pitch. Gear profile deviation: In a complete tooth p

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, w
