Description

Technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a fatigue test bench for a flexible wheel of a robot harmonic reducer. Background technique [0002] The harmonic reducer includes a rigid gear (rigid gear) with an inner ring gear, a flexible gear (flexible gear) with an outer gear ring, and a wave generator. Harmonic reducer has the advantages of small size, light weight, smooth transmission, no impact, no noise, high motion precision, large transmission ratio, and high carrying capacity. It is widely used in electronics, aerospace, robotics and other industries. [0003] The harmonic reducer needs to ensure the stability of its performance due to the particularity of its scope of use. Therefore, it is necessary to inspect a number of performance parameters of the harmonic reducer. During use, the flexspline bears a large alternating load, and the flexspline and the rigid gear are meshed transmission. Therefore, the torsion...

AI Technical Summary

Problems solved by technology

In the process of use, the flexspline bears a large alternating load, and the meshing transmission between the flexspline and the rigid spline, so the torsional performance of the flexspline and the meshing performance of the gear need to be tested. At present, the detection methods of this project are usually For manual destructive detection, place the harmonic reducer on the running equipment and keep it running until the components of the harmonic reducer are damaged, and record the time. The data obtained by this detection method is not accurate enough, and Can not truly reflect the various performance parameters of the harmonic reducer
