Rapid service life testing device and method applied to precision speed reducer

Abstract

The invention relates to a rapid life test device and method applied to a precision decelerator, an input end and an output end of the precision decelerator to be tested are respectively connected with a driving motor and a swing arm, under the driving of the driving motor, the input end of the precision decelerator rotates, and then the output end of the precision decelerator drives the swing arm to swing; a sliding rail, a driving device and a sliding block are arranged on the swing arm, the sliding block is installed in the sliding rail in a sliding mode, a balancing weight is installed on the sliding block, the driving device is matched with the sliding block and the sliding rail, the sliding block slides along the sliding rail under the action of the driving device, and then the balancing weight is driven to move on the swing arm. Compared with the prior art, the movable balance weight is additionally arranged on the swing arm, and the movable balance weight can move along with the change of the motion angle of the swing arm, so that the acting moment acting on the precision speed reducer is adjusted, and the acting moment acting on the speed reducer is the maximum moment all the time; and the service life test time of the precision speed reducer can be reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of product testing, in particular to a fast life testing device and method applied to a precision reducer. Background technique [0002] Precision reducers are the core components of robots. With the rapid development of the manufacturing industry, there is a large demand for precision reducers. In order to break the pattern of all precision reducers relying on imports, it is necessary to independently develop precision reducers. [0003] The service life is an important performance parameter of the precision reducer. In order to ensure the reliability of the precision reducer, the fatigue life test of the precision reducer during the research and development process is particularly important. The quality of the test device directly affects the progress of product development. Therefore, it is necessary to start the development and testing of various types of precision reducers, and require corresponding te...
