Torsion detection method for two-stage gear reducer

Abstract

The invention provides a torsion detection method of a two-stage gear reducer, which comprises the following steps: S1, applying a torsion force to a gear of the reducer, and sensing a torsion value required for rotating the gear, S2, clamping a first end of the gear by a clamping wrench, and clamping a second end of the gear by a torque wrench, S3, applying a stable force by the torque wrench to gradually increase the torque, and S4, detecting the torsion value required for rotating the gear. When the nut or the bolt just starts to slightly rotate, the instantaneous torque value of the nut or the bolt is the maximum, the nut or the bolt continues to rotate, the torque value falls back to a transient stable state, the torque value is the torque obtained through detection, and the method is easy to operate, simple in tool and high in applicability.

Description

technical field [0001] The invention mainly relates to the field of torsion force detection, in particular to a torsion force detection method of a secondary gear reducer. Background technique [0002] Generally, in order to reduce the speed and increase the torque of the motor power output, a reducer is usually installed at one end of the motor power. Through various mechanism designs, the speed of the motor is reduced and the torque is increased. The common torque testing machine is used For measuring the limit of torsional force that long objects such as rods, bolts or mandrels can withstand, few torsion testing machines can be used to accurately measure the torsional strength, durability and torsion force output by the reducer device. limit. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects of the prior art, the present invention provides a torque detection method for a two-stage gear reducer, comprising the following steps: [0004] S1: Apply ...
