Gear reducer sealing requirements

The gearing requirements of gear reducers are very high and it is important to give them a good seal. Because the gear reducer is usually installed in a place with poor environmental conditions, if the inhaled air contains particulate matter, dust, or corrosive gas, it will affect the service life of the compressor oil. Therefore, it is recommended to consider installing an air intake filter for the gear reducer, and always clean and periodically replace the air intake filter. In addition, the sealing requirements of the gear reducer are that no gaskets are allowed to be filled between the split faces of the box, but sealant or water glass can be applied to ensure the seal. Also, when assembling the gear reducer, the seal between the cover and the joint surface of the case should be checked with a stopper of 0.05 mm before tightening the bolts of the case, and the shaft seal should be coated with grease. In addition, the sealing devices of the gear reducer should be installed in s

Influence of ambient temperature difference on gear reducer

The environment will affect the growth of people, and it will also affect the work of the gear reducer . When the temperature of the continuous operation of the machine is too high, and the ambient temperature does not reach the temperature of the machine, the temperature rise is too large and it is easy to affect the normality of the gear reducer. Run, then what is the temperature rise? Temperature rise is the temperature difference between the gear reducer and the environment, and is mainly used to measure the degree of heat generation of the gear reducer. The core of the gear reducer in operation will produce iron loss in the alternating magnetic field, copper loss will occur after the winding is energized, and other stray losses will occur, which will increase the temperature of the gear reducer. However, the gear reducer will also dissipate heat. When the heat is equal to the heat dissipation, the equilibrium state is reached, and the temperature does not rise and stabilizes at

Gear reducer use attention

In order to ensure the normal and stable operation of the gear reducer , what should we pay attention to when using the gear reducer? Let's follow the Xinghai reducer to understand this aspect. First of all, regarding the normal operation of the gear reducer, the quality of the equipment is undoubtedly the most important and the most important point of attention. Whether it is for professional technicians or ourselves to install and disassemble, special tools must be used. In addition, the accessories used in this installation/disassembly process should be installed with original accessories or pairs of accessories. replace. Secondly, the gear reducer is a high-loss device, there is no good lubricant and additive, the gear reducer can not have a long service life and high work efficiency. Generally speaking, the gear reducer adopts 220# gear oil. For heavy-duty gears with frequent load and frequent start-up and poor use environment, some lubricating oil additives can be selecte

Gear reducer installation and maintenance

The gear reducer is more stable, safe and reliable than the electronic speed control device in terms of deceleration and increased torque value. Therefore, the product is not only promising at present, but also widely used. Here is a brief introduction to the gear reducer. Installation and use. First of all, in the installation and use of the gear reducer, if you need to lift the gearbox, you should use the eyebolt. Moreover, the product should be protected from moisture during transportation and storage. In addition, if the gear reducer is not installed within half a year after purchase, the exposed machined surface should be recoated with anti-rust oil. Secondly, during the installation and use of the gear reducer, the product must be rigidly fixed to a solid foundation surface, and all anchor bolts must be spring washers. Also, the mounting error of the coupling should not exceed its allowable deviation. Furthermore, the gear reducer undergoes a rigorous test run test before

Under what circumstances does the gear reducer detect the insulation resistance?

Insulation resistance of gear reducer , as its name suggests, is used to reduce the current and voltage flowing through the gear reducer while maintaining a relatively stable current and voltage environment. Then, under what circumstances does the insulation resistance of the gear reducer need to be tested? 1. The newly purchased gear reducer needs to be tested for insulation resistance before it is put into use. 2. The gear reducer has not been used for at least 3 months, and is put into use again; 3. When the gear reducer encounters a fault for minor repairs or large repairs, it is also necessary to test its insulation resistance; 4. After the equipment is damp due to special reasons, the insulation resistance must be tested to prevent the gear reducer from malfunctioning during use. Under normal circumstances, we test the insulation resistance of the gear reducer is carried out using a shaker. Because the DC test voltage generated by the shaker is constant, and the voltage le

Advantages of helical gear reducer relative to spur gear

The disadvantage of spur gear reducers relative to helical gear reducers is that they generate vibration. Some variations in the involute profile may occur along the entire tooth surface at the same time, whether due to design, fabrication or deformation. This will result in a regular, one-to-one contact, which is often very intense. The resulting vibration causes both a large load on the gear and noise. A further disadvantage of the spur gear reducer is that during the contact time, the additional strength sometimes obtained by the engagement of the two pairs of teeth cannot be utilized because the stress is limited by the condition of single tooth engagement in the cycle. The helical gear reducer is different, and its helical gear can be seen as a cylindrical gear that is placed in a misaligned position by a set of thin-toothed gears, so that the contact of each piece is at different parts of the tooth profile, thereby compensating each thin plate. The effect of the gear error,

Why does the gear reducer break the shaft?

Why does the gear reducer present a problem of broken shafts, and the gear reducer is a common problem. Except for the broken shaft of the reducer due to the poor concentricity of the output device of the reducer, if the output shaft of the reducer is broken, it is due to the following reasons. 1. In the process of accelerating and decelerating, if the output torque of the gear reducer is multiplied by the torque of the brake, if it exceeds twice the extra output torque, and the acceleration and deceleration are too frequent, then the reducer will eventually Broken shaft. I think that this kind of appearance is less, so I will not introduce it further here. 2. The selection of the fault causes the output of the gearbox to be insufficient. Some users mistakenly believe that only the additional output torque of the selected gear reducer can satisfy the operation demand. In fact, otherwise, the additional output torque of the motor is multiplied by the reduction ratio, and the obtain

Need to pay attention to the gear reducer seal

Gear reducers are usually installed in places with poor environmental conditions. Inhalation of air containing particulate matter, dust, and corrosive gases can affect the service life of compressor lubricants. It is recommended to consider installing air intake filters, and should be cleaned regularly and periodically. Intake filter. The gears of the gear reducer should pay attention to the following points: 1. Do not fill any gasket between the split surfaces of the box, but apply sealant or water glass to ensure sealing; 2. When assembling, before tightening the box bolt, use a 0.05mm feeler gauge to check the tightness between the joint surface of the box cover and the box seat; 3. The shaft extension seal should be coated with grease. Each sealing device should be installed in strict accordance with the requirements. Portal:https://www.zwgearbox.com/

Gear reducer selection

The selection principle of the gear reducer is mainly based on the characteristics of the device itself and the load, and the nature of the power supply. During the use of the gear reducer, the motor that does not match its nameplate cannot be replaced at will. Of course, when selecting a gear reducer, consideration should also be given to the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors. At the same time, for different types and models of gear reducers, compare their outer dimensions, transmission efficiency, load capacity, quality, price, etc., and choose the most suitable equipment. In addition, because the load state of the working machine connected with the gear reducer is relatively complicated, it has a great influence on the equipment, and is therefore an important factor in the selection and calculation of the gear reducer. In general, the load state of the gear reducer, that is, the load st

Gear reducer adapter motor input maximum speed

Gear assembly body assembly must first ensure that the stiffness of the gears, shafting and box meets the design requirements. The bearing clearances used on the same shaft should be consistent, and the assembly should be carefully assembled. The gear reducer adapts to the maximum input speed of the motor. It is generally controlled at 2000 rpm. Because the excessive speed is a test for the bearing oil seal, it is very likely that the gear reducer will see oil leakage for a long time. However, since the rotary support of the gear reducer is mainly supported by the two bearings thereon, the increase of the distance between the two bearings can increase the rotational stability and load carrying capacity of the gear reducer. Therefore, the round nut is used to adjust the axial clearance between the two bearings, the adjustment is convenient and reliable, and the normal operation of the gear reducer can be ensured.

Gear reducer running-in period considerations

In practical applications, the newly purchased gear reducer requires a running-in period, and the correct running-in can greatly extend the life of the equipment. Before use, the operator should accept the manufacturer's guidance, training, or read the instruction manual in detail, understand the structure and performance of the gear reducer, and have certain operation and maintenance experience before operating the reducer. The following article will explain in detail what you should pay attention to. Let's take a look at it. 1. Pay attention to limit the working load of the gear reducer during the running-in period. The working load of the reducer during running-in should not exceed 85% of the rated working load, and arrange the working time to avoid overheating of the reducer. happened. 2. During the running-in period, pay attention to the operation of the gear reducer due to the frequent observation. If there is any abnormality, stop and eliminate the abnormality in ti

Reducer is widely used in machinery industry

With the wide application of the reducer in the machinery industry, our understanding of the common sense of the reducer needs to be strengthened. Only by knowing the knowledge of the reducer can we better operate the reducer. We have done our knowledge of the common sense of the reducer.
