Abstract

The invention discloses a precision speed reducer static performance test bench comprising main components including a servo motor, a torque rotating speed sensor, a high-precision encoder, a speed reducer under test and a magnetic powder clutch as well as fixedly connected auxiliary components including a base, a horizontal slide bench, a coupling, a reducer mounting seat, etc. The magnetic powder clutch is used to supply an input end load, the servo motor provides an output end load, and a testing device of the angle amount and the rotating speed amount is added in the middle to test the static performance of the precision speed reducer. According to the definition of each static performance parameter of the precision speed reducer, static performance testing of hysteresis, torsional stiffness and the like can be done on the same test bench, and static performance of different types of precision speed reducers can be tested; and the test bench adopts a program-controlled loading method with high degree of automation. The test bench has the advantages of simple structure, high testing precision, low requirement for testing environment and high degree of automation, and can meet the testing and measurement requirements of industrial robots for the static performance of precision speed reducers.

Description

technical field [0001] The invention relates to the technical field of static performance testing of a precision reducer, in particular to an experimental bench for static performance testing of a precision reducer for industrial robot joints. Background technique [0002] With the acceleration of the industrialization process, my country has become the world's largest manufacturing country. However, with the advent of China's aging society and rising labor costs, the upgrading of traditional industrialization has become a top priority. Therefore, the development of intelligent manufacturing technology with industrial robots as the core has become the only way. As a precision reducer for joint parts of industrial robots, its static performance has an extremely important impact on the product quality of industrial robots. [0003] The static performance of the precision reducer mainly includes indicators such as backlash and stiffness. The hysteresis refers to the phenomen...
