Abstract

The invention discloses an RV reducer comprehensive test bench, which can test multiple performance parameters such as the angle transfer error, the return difference, the torsional rigidity, the service life, the temperature rise, the efficiency and the torque of the high-precision RV reducer. The RV reducer comprehensive test bench comprises a base, and a servo motor, a linear motor, a first torque sensor, a first high-precision angle encoder, a to-be-tested RV reducer bracket, a mounting flange disc, a temperature sensor, a second torque sensor, a second high-precision angle encoder, a diaphragm coupling and a brake arranged above the base. The mounting flange disc can be replaced, and thus, test on reducers of multiple types can be realized. compared with other test instruments, the RV reducer comprehensive test bench of the invention has the advantages that the test efficiency and the test precision are greatly enhanced; the performance is reliable; the test repetition is good; the operation for replacing a tested object is simple; the mounting and positioning precision is high; and the cost is low.

Description

technical field [0001] The invention relates to a comprehensive test bench for an RV reducer, which belongs to the fields of precision test and measurement technology, precision instruments and mechanical transmission. Background technique [0002] With the rapid development of industrial robots, RV reducers are used in the joints of industrial robots and are one of the core components of the entire robot. Its accuracy is crucial in industrial robots. Industrial robots have requirements for RV reducers such as large transmission ratio, high rigidity, high motion precision, high transmission efficiency, and small hysteresis. The performance indicators of the RV reducer include: hysteresis, angular transmission error, torsional rigidity, transmission efficiency, temperature rise, torque rigidity, etc. [0003] When the RV reducer is widely used, it is necessary to strictly test the performance of the RV reducer, so many test platforms have been widely used. However, the exis...
