The performance of the harmonic reducer is determined by the return clearance, transmission error, transmission efficiency and service life. Its return clearance determines the accuracy level of the product, so what is the return clearance of the harmonic reducer?
The backlash of the harmonic reducer is also called backlash, which means that the output end is fixed, the input end rotates clockwise and counterclockwise, so that the input end produces rated torque +-2% torque, and the input end has a slight angular displacement , This angular displacement is the return gap, the unit is "arcmin", which is one sixtieth of a degree. For example, when the return gap is marked as 1arcmin, it means that the reducer rotates once, and the angular deviation of the output end is 1/60°. In practical applications, this angular deviation is related to the shaft diameter b=2·π·r·a°/360°, that is, when the output radius is 500mm, the gearbox accuracy is jt=3′, that is, a°= 3/60, the deviation of one revolution of the reducer is b=0.44mm. A return gap of not less than 5° means that the return gap is greater than 1/12 degrees, that is, when the driving wheel rotates more than 1/12 degrees, the driven wheel can act accordingly.
The lower the return gap value of the harmonic reducer, the better, the product accuracy level of the return gap ≤ 10 arc second is level 1, 10 arc second
