Abstract

The invention discloses a device for testing whole life cycle precision degeneration of an RV reducer. A sliding plate driven by a driving mechanism is arranged on a flat plate. A mounting support isfixed to the sliding plate, a servo motor and the RV reducer to be tested are fixed to the mounting support, and the output end of the servo motor is connected with the input end of the RV reducer. Abearing pedestal support is fixed to the flat plate, a left stand plate and a right stand plate are arranged on the bearing pedestal support, a bearing assembly and a coder are mounted on the left stand plate, an output flange is arranged on the side, close to the RV reducer, of the left stand plate, and after the output flange and the RV reducer are in contact, fixed transmission can be achieved.A loading shaft is mounted on the right stand plate through a bearing assembly, an output flange shaft penetrates through the bearing assembly and a hole in the coder to be connected with one end ofthe loading shaft through a coupler, and the other end of the loading shaft is connected with a loading rod with a balance weight. According to the device, the reducer transmission error in the complete period of a fatigue life experiment can be tracked and tested in real time, and the transmission error of the reducer in the state of bearing variable loads can be tested.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for testing the accuracy degradation of an RV reducer in its entire life cycle. Background technique [0002] As the most important reducer for robot joints, RV reducer has a series of advantages such as small size, light weight, wide range of transmission ratio, high bearing capacity, high precision, high efficiency, and stable transmission. The quality of its transmission performance directly affects the overall performance of industrial robots. [0003] With the continuous improvement of industrial production automation and precision, the demand for industrial robots is increasing rapidly, and it is more and more important to develop and develop high-performance reducers. At present, the equipment for testing the transmission error of RV reducer focuses on the single measurement of no load and even load to obtain the transmission error. There is no test equipment for real-time a...
