Problems solved by technology

This method uses the load arm to add load to the output end of the tested reducer, and uses the servo motor to load the input end of the tested reducer. According to the patent description, this system cannot test the transmission efficiency of the reducer under the specified load, and cannot test the specified The torsional rigidity at one angle point cannot test the performance of various types of precision reducers, and the torsional rigidity and transmission efficiency cannot be tested on the same device, and the torsional rigidity test range is small, the test efficiency is low, and it is inconvenient to install and disassemble.
