Description
technical field [0001] The invention relates to a harmonic reducer testing technology, in particular to a load testing device and method for a harmonic reducer with electric energy feedback. Background technique [0002] Harmonic reducers have the advantages of small size, high transmission ratio, and high precision. They have been widely used in robotics and military fields, and are an important transmission component. [0003] In the design verification of the harmonic reducer, load testing and life testing are required to verify its quality and performance. The existing test method is to connect the driving motor coaxially with the harmonic reducer to provide rotational force, and then connect the load motor or other adjustable load to the output end of the harmonic reducer, and consume the mechanical energy at the output end in resistance equipment or On the braking resistor, among them, the life test of the harmonic reducer requires a continuous load test of not less t...
