SD-BRG Zero Backlash Precision Cycloidal Replace Planetary Gearboxes

Technical Advantages

● Zero Backlash

Using movable gear transmission technology， steel balls are used to replace the traditional fixed gear teeth， through preloading and cycloid raceway

to form a backlash-less rolling mesh pair, to achieve zero backlash, high precision.

● High Load

The output adopts crossed roller bearing (plane thrust bearing + cylindrical roller bearing) , and all the steel balls are engaged in meshing transmission

with high contact degree, with high bearing capacity and overload capacity

● Low Noise

Transmission Meshing Mechanism belongs to rolling contact mode, no clash and impact, low operating noise.

● Wide Ratios

Adopt differential speed transmission method, can realize wide ratio range of 6~2000, large speed ratio structure can achieve the same volume width

as small speed ratio.

● High Efficiency

The steel ball and the cycloid raceway adopt rolling contact meshing, effectively reduces the friction resistance in operation, thus the transmission

efficiency is high.

● Long Service Life

The rolling friction transmission method is applied to effectively reduce the temperature rise and wear during operation, and the design life is long.
