The embodiment of the invention discloses a speed reducer transmission error testing method and device. The testing device comprises a base, a test tool, a driving assembly, a detection assembly and a receiving assembly; the test tool is arranged at the output end of a to-be-tested speed reducer; the speed reducer is fixed on the base; the output end of the driving assembly is connected with the input end of the speed reducer, so that the driving assembly is used for driving the input end of the speed reducer to rotate and determining rotation angle information of the input end of the speed reducer; the detection assembly comprises a laser tracker located on one side of the output end of the speed reducer and a target ball arranged on the test tool; the target ball is matched with the laser tracker so as to be used for determining motion trail information of the target ball; and the receiving assembly is used for determining the transmission error of the speed reducer according to the rotation angle information of the input end of the speed reducer and the motion trail information of the target ball. The speed reducer transmission error testing method can be widely used in practical application.
Description
technical field [0001] The present application relates to the fields of precision testing technology and mechanical transmission technology, and in particular, relates to a transmission error testing device and method of a reducer. Background technique [0002] The transmission error of the reducer is the difference between the theoretical output and the actual output of the reducer during the motion process. It is a direct expression of the quality of the internal teeth of the reducer and the meshing of the teeth. It essentially reflects the tooth shape design and Actual processing level. The detection of the transmission error of the reducer is the detection of the input and output angles during the movement of the reducer. [0003] At present, the synchronous acquisition of the rotation angle of the input end and output end of the reducer is mainly done by installing a circular grating at the input end and output end of the reducer, and the circular grating is a high-pre...
