Cycloid pin reducer and worm gear reducer are both commonly used mechanical transmission devices. They have some differences in structural characteristics, as follows:
Structural characteristics of cycloid pin wheel reducer
Compact structure: adopts planetary transmission principle, the input shaft and output shaft are on the same axis line, so that its model can achieve 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
Structural characteristics of worm gear reducer
Complex structure: mainly composed of worm gear, worm, shaft, bearing, box and 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 is adopted: the meshing between the worm gear and the worm is a sliding friction, which is prone to wear and heat, and requires good lubrication and heat dissipation measures.
