We all know that a gearbox is a type of transmission component that works mainly through the coordination between gears. And clearance refers to the gap between gears - generally also known as return clearance. So today, in order to deepen everyone's understanding and facilitate later use, let me introduce in detail the relevant content about the backlash of the reducer:
The return clearance of the reducer: Simply put, it means fixing the output end and rotating the input end clockwise or counterclockwise to generate a rated torque of+2 percentage and -2 percentage at the output end. There is a small angular displacement at the input end - this angular displacement is the return clearance, measured in "arc minutes", which is one sixtieth of one degree (=60 Arcmin=60 '). When the return clearance is marked as 1arcmin, it means that the angular deviation of the output end after one rotation of the reducer is 1/60 °.
In practical applications, this angular deviation is related to the shaft diameter, such as b=2 ·π · r · a °/360 °. This means that when the output radius is 500mm and the gearbox accuracy is jt=3 ′, i.e. a °=3/60, the deviation of the reducer after one revolution is b=0.44mm; For a return clearance of not less than 5 degrees, it means that the return clearance must be greater than 1/12 degree - that is, the driven wheel can only have corresponding action when the driving wheel rotates more than 1/12 degree.
Ordinary reducers rarely consider the issue of backlash while meeting the requirements of output torque, speed, etc., so we cannot find corresponding parameters in our sample. However, we still hope that everyone can understand this knowledge and operate the reducer better!
