• The difference between performance parameters of cycloid pinwheel reducer and worm gear reducer

  High-speed ratio and high efficiency of cycloid pin wheel reducer: Single-stage transmission can achieve a reduction ratio of 1:87, with an efficiency of more than 90%. If multi-stage transmission is used, the reduction ratio is greater. Stable operation and low noise: the cycloid needle teeth have a large number of meshing teeth, a large overlap coefficient, and a mechanism of mechanical balance, so that vibration and noise are limited to the minimum degree. Reliable use and long service life: Because the main parts are made of high-carbon chromium steel, they are quenched (HRC58~62) to obtain high strength, and some transmission contacts use rolling friction, so they have a long durable life. Large torque output: It can output large torque, suitable for equipment that requires large torque drive. Small backlash and backlash: Usually output from the surface, the backlash and backlash are very small, and the imported ones can usually be controlled within 10 arc minutes. The transmission ratio of the worm gear reducer is large: a large reduction ratio can be achieved, generally between 10-80, and can reach a maximum of more than 100.

• The difference between structural characteristics of cycloid pinwheel reducer and worm gear reducer

  Cycloid pin wheel reducer and worm gear reducer are both commonly used mechanical transmission devices. They have some differences in their structural characteristics, as follows: The structural characteristics of the cycloccipitor pin wheel reducer are compact in structure: using planetary transmission principle, the input shaft and output shaft are on the same axis line, so that its model can obtain the smallest size possible. Small number of parts: mainly composed of eccentric sleeves, cycloid wheels, needle gears, output shafts and other parts, and the structure is relatively simple. Rolling friction is adopted: the meshing between the cycloid wheel and the needle gear is rolling friction, which reduces wear and improves transmission efficiency and service life. The structure of the worm gear and worm reducer is complex: it is mainly composed of worm gear, worm gear, shaft, bearing, box and its accessories. There are many parts: In addition to worm gears and worms, they also include shafts, bearings, boxes, end covers, oil seals and other parts. Sliding friction: The meshing between the worm gear and the worm is a sliding friction, which is easy to produce wear and heat, and requires good lubrication.

• Notes on the use of single-stage vertical XLD5-23-5.5KW cycloid pinwheel reducer

  Notes on the use of single-stage vertical XLD5-23-5.5KW cycloid pin wheel reducer: When installing, the horizontality and verticality of the reducer should be ensured to avoid unstable or damaged operation of the reducer due to improper installation. When connecting reducers to motors or other equipment, appropriate couplings or pulleys should be used to avoid vibration or noise during operation of the reducer due to insolid connection. In terms of lubrication, the reducer should be lubricated with appropriate lubricating oil. The model and specification of the lubricating oil should be selected according to the use requirements and working environment of the reducer. During the operation of the reducer, the oil level and quality of the lubricant should be checked regularly, and the lubricant should be supplemented or replaced in time to ensure the normal operation of the reducer. In terms of load, the output shaft of the reducer cannot be subjected to large axial and radial forces. Other measures must be taken when there are large axial and radial forces, such as adding support or using special bearings. When selecting a reducer, it should be based on the actual load

• What impact does ambient temperature have on the output torque of the four series S47-30.33-1.1KW reducer

  The ambient temperature has the following impact on the output torque of the S47 reducer: Changes in the performance of lubricating oil in the high-temperature ambient: Increased temperature will reduce the viscosity of the lubricating oil in the reducer. After the viscosity of the lubricating oil decreases, the thickness of the oil film formed between transmission parts such as gears becomes thinner, and the load-bearing capacity decreases, resulting in an increase in friction during transmission. This will not only reduce transmission efficiency, but also consume an additional part of the torque, which will eventually lead to a decrease in output torque. At the same time, high temperatures may also reduce the antioxidant performance of the lubricant, accelerate the deterioration of the oil, further affect the lubricating effect, and aggravate the loss of torque. Thermal expansion of components: High temperatures will expand the metal parts of the reducer. The degree of expansion of different components may vary, which will cause the gear meshing clearance to become smaller and even jamming; or the mating accuracy of bearings and other components will be reduced, resulting in additional resistance. These will increase the operating resistance of the reducer, which requires more torque to overcome, thereby causing the output torque

• What are the common faults of B series planetary BWD0-17-0.37KW cycloid pinwheel reducer

  The B series planetary BWD0-17-0.37KW cycloid pin wheel reducer, the common faults are as follows: Serious causes of heat generation: The reducer is too large and overloaded for a long time; poor heat dissipation conditions, such as installation in a poor ventilation area; improper lubricant selection or too high or too low oil level affects the heat dissipation effect. Solution: Reasonably select the reducer model to ensure that it can withstand actual workloads; improve the installation environment to ensure sufficient ventilation space around; select appropriate lubricant and add or reduce lubricant according to the specified oil level. Causes of oil leakage: The seal is aging and damaged, resulting in oil leakage; the joint surface of the box is not tight and there are gaps; the oil level is too high, causing the oil to be squeezed out from the ventilation holes or other gaps. Solution: Check the seal regularly and replace it in time if it is found to have aging or damage; seal the joint surface of the box, such as applying sealant; adjust the oil level to normal height. Causes of excessive noise: gear wear, tooth precision decreases, resulting in

• R77-YEJ1.5-4P-57.68-M1-270 What are the reasons for damage to the seal of the helical gear reducer

  R77-YEJ1.5-4P-57.68-M1-270 The main reasons for damage to the seals of the helical gear reducer are as follows: Improper installation and assembly problems: When installing the seal, if the installation method is incorrect, such as the offset or twist of the seal installation position, or damage to the seal during installation, it will cause the seal to fail to work normally, thereby causing damage. The fitting accuracy between the shaft and the seal is insufficient: the dimensional accuracy and surface roughness of the shaft do not meet the requirements, or the fitting gap with the seal is too large or too small, which will affect the sealing effect. If the gap is too large, it will cause the medium to leak; if the gap is too small, it will increase the wear of the seal and shorten its service life. Working environment factors are too high: If the heat generated by the reducer cannot be dissipated in time during operation, it will cause the oil temperature to rise, causing the seal to age and deform, and reduce its sealing performance. For example, when the reducer is in a poorly ventilated environment

• What measures should be taken to deal with ambient temperature changes when maintaining the S97-50.63-11KW reducer

  When maintaining the S97 reducer, the following measures can be taken to deal with environmental temperature changes: Response to high-temperature environments to strengthen ventilation and heat dissipation: Ensure that there is enough space around the reducer and maintain good ventilation conditions. You can set up ventilation ports or install fans at the installation location to accelerate air circulation and take away the heat generated by the reducer. Installing a cooling device: For S97 reducers that run for a long time in high temperature environments, consider installing a cooling device, such as cooling water pipes or cooling radiator. Reduce the oil temperature of the reducer by circulating cooling water or heat sink. Choose a suitable lubricant: According to the characteristics of the high temperature environment, choose a lubricant with high flash point and low viscosity index. Such lubricating oil can maintain good flowability and lubricity at high temperatures, reducing energy loss and wear. At the same time, check and replace the lubricant regularly to ensure its performance is good. Monitoring temperature: Install temperature monitoring devices, such as thermometers or temperature sensors, and monitor in real time

• What adverse effects will different centers of the drive shaft have on the reducer

  Different centers of the transmission shaft will have the following adverse effects on the reducer: Increased wear: Different centers of the transmission shaft will cause the gears, bearings and other components inside the reducer to bear additional radial and axial forces. This will cause the gear meshing accuracy to decrease, the wear of the tooth surface is intensified, and the service life of the gear is shortened. At the same time, the bearing will also suffer excessive wear due to uneven stress, which may even cause bearing failure, affecting the normal operation of the reducer. Generate vibration and noise: Due to the different centers of the transmission shaft, unbalanced centrifugal force will be generated during operation, which will cause vibration of the reducer. This vibration will not only affect the stability of the device, but also produce noise. Long-term vibration will loosen the connecting parts of the reducer, further aggravating the damage to the equipment, and the noise will also have adverse effects on the working environment. Reduce transmission efficiency: The transmission shaft with different centers will cause energy loss during power transmission, resulting in a reduction in the transmission efficiency of the reducer. This is because of the extra force and vibration
