Which is more suitable for high-speed transmission, cycloidal pinwheel reducer or worm gear reducer
Compared with worm gear reducers, cycloidal pinwheel reducers are more suitable for high-speed transmission, mainly for the following reasons:Transmission efficiency:
Cycloid pinwheel reducer: The needle teeth mesh through rolling friction, and the first stage reduction efficiency is as high as about 94%. In high-speed transmission, the efficiency loss is relatively small, which can better maintain power transmission, reduce energy loss and heat generation.
Worm gear reducer: The efficiency of worm gear transmission is relatively low, generally between 30% and 80%. This is due to the relatively small meshing area of the worm gear, resulting in significant friction loss. During high-speed transmission, more heat is generated, which further reduces efficiency and may even affect the normal operation of the gearbox.
Input speed range:
Cycloid pinwheel reducer: It can generally be integrated with planetary gears and can adapt to high input speeds. It can usually operate stably at relatively high speeds and has a wide range of reduction ratios. The single-stage transmission reduction ratio can reach 9-87, the two-stage transmission reduction ratio can reach 121-5133, and the multi-stage combination has a wider reduction ratio of 36.
Worm gear reducer: allows a lower input speed range of 6. Due to its low transmission efficiency, it generates a large amount of heat during high-speed operation. At the same time, high-speed rotation may exacerbate the wear of worm gears and worm gears, affecting their service life and transmission accuracy.
Transmission smoothness and noise:
Cycloid pinwheel reducer: During operation, there are a large number of teeth in contact with each other, resulting in a high degree of overlap and smooth operation, with low vibration and noise. During high-speed transmission, it can also maintain good stability and reduce the generation of vibration and noise.
Worm gear reducer: Although the transmission is smooth and can reduce noise and vibration in gear transmission, in high-speed transmission, due to the generally small helix angle of the worm and the large friction loss, more heat and noise may be generated, which affects the smoothness of the transmission.
In summary, the cycloidal pinwheel reducer has significant advantages in high-speed transmission. However, in practical applications, it is necessary to comprehensively consider factors such as specific working environment, load requirements, installation space, etc. to choose the most suitable reducer.
