Special machine for testing comprehensive performance parameters of RV speed reducer

Abstract

The invention discloses a special machine for testing comprehensive performance parameters of an RV speed reducer, and the special machine comprises a rack, wherein the rack is provided with a torqueloading servo motor, a test bed positioned below the torque loading servo motor and an input servo motor positioned below the test bed, the upper end surface of the test bed is provided with a placingarea for placing the speed reducer to be tested, the output end of the torque loading servo motor faces the test bed, the output end of the torque loading servo motor is provided with an output torque rotating speed sensor, an output coupler, an output angle encoder and an output connecting flange, the output end of the input servo motor faces the test bed, and the output end of the input servo motor is provided with an input torque rotating speed sensor, an input coupler and an input angle encoder. The torque loading servo motor, the test bed and the input servo motor are arranged along thevertical direction, namely, a vertical platform is adopted, so that the test bed is convenient for testers to work, the mounting accuracy can be ensured, and the occupied area is small.

Description

technical field [0001] The invention relates to a test device in the field of motor detection research, in particular to a special machine for testing comprehensive performance parameters of an RV reducer. Background technique [0002] In 1926, the German Lorenz Brown creatively proposed a planetary transmission mechanism with small tooth difference, which used the epicycloid as the tooth profile curve. One of the gears is in the form of a pin wheel, and this transmission is also called cycloidal pin wheel planetary gear transmission. RV transmission is a brand-new transmission method, which is developed on the basis of traditional pendulum planetary transmission, which not only overcomes the shortcomings of general needle pendulum transmission, but also has the advantages of small size, light weight, large transmission ratio range and long life. , stable precision, high efficiency, stable transmission and a series of advantages. [0003] RV reducer includes Cheng RV-E ser...

AI Technical Summary

Problems solved by technology

In the prior art, there are still some disadvantages: it is impossible to simulate the loading torque of the reducer, that is, it is impossible to test the important performance parameter of torsional rigidity, which is out of the actual working environment; the versatility is poor, the input and output must be coaxial, and for non-coaxial Such reducers cannot be tested; the existing test equipment is horizontal and occupies a large area. Every time the reducer is replaced for testing, it needs to be corrected with a watch, which takes a long time
