SD-BRG Zero Backlash Precision Cycloidal Replace Planetary Gearboxes
Major Applications: High precision robotics and semi conductor devices, industrial automation such as machine tools, printing, packaging machinery, military and aerospace, material handling, food and tobacco, medical device, pharma, assembly and test, sheet metal, CNC machine etc.
● 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.
