There are many factors to consider when choosing a planetary reducer.If Selection is small, the reducer cannot bear the load or other conditions after running; a large selection will cause a waste of resources.The selection of a planetary reducer needs to consider many factors, including load, torque, backlash, inertia, accuracy, installation size, and speed, because some values have been determined, mainly including whether the speed ratio, torque, and accuracy meet the operating requirements.Today, I will introduce the relevant formulas and some knowledge about the calculation of the planetary reducer Selection.
1. Speed ratio Selection: reducer input speed ÷ reducer output speed = final speed ratio
2. Torque: reducer torque>servo motor output torque×speed ratio
3. Accuracy: the return clearance of the reducer (back clearance, clearance, rotary clearance), select according to the requirements of the equipment
Selection Planetary reducer
1. Calculate the load torque
T=9550 × p1/n2=9550 × 3/360=79.58Nm
2. Calculate the output torque of the reducer
T2N≥T × f1=79.58 × 1.25=99.475Nm
3. Select a reasonable reducer according to the reduction ratio, output torque of the reducer, input motor terminal size, and output device terminal size.
Load type: Each load type has different working conditions, different parameters, and different calculation methods.Various applications of common electric motors and planetary reducers, such as rack and pinion, ball screw, belt, conveyor belt, turntable, crankshaft and winding mechanism.
