The vertical experiment table comprises a mounting bracket, a drive motor, an input end torque instrument, an output end angle encoder, an output end torque instrument and a thrust disc, wherein the drive motor is vertically mounted on the mounting bracket; the input end torque instrument is connected with the output shaft of the drive motor and the input shaft of the tested reducer respectively; the output end angle encoder is connected with the output shaft of the tested reducer; the output end torque instrument is connected with the output shaft of the output end angle encoder; the thrust disc is connected with the output shaft of the output end torque instrument; the drive motor is provided with a motor end angle encoder; and the drive motor and the input end torque instrument are connected through a rigid coupling. By vertically arranging the drive motor, the tested reducer, the output end angle encoder and the output end torque instrument, the vertical experiment table effectively avoids the assembly error caused by gravity, is convenient to mount and debug, is high in degree of automation, high in test precision and great in generality, and can test multiple dynamic characteristics of the tested reducer at the same time.

Description

technical field [0001] The invention relates to a speed reducer testing device, in particular to a vertical test bench for precise performance testing of a planetary speed reducer with small tooth difference, which is mainly used for performance testing of general-purpose harmonic speed reducers or filter speed reducers. Background technique [0002] Harmonic reducers are increasingly widely used in precision transmission fields such as aerospace, instrumentation, robot joints, and machine tools due to their advantages such as high precision, low noise, light weight, and large speed ratio. The operating state of the harmonic reducer directly affects the performance of the entire transmission system. In order to ensure its high precision, high reliability and long life, this requires us to accurately grasp the operating performance of the reducer through necessary static and dynamic tests and analysis. [0003] Traditional harmonic reducer performance test benches are all ho...

AI Technical Summary

Problems solved by technology

[0003] Traditional harmonic reducer performance test benches are all horizontal, and generally only one or two dynamic characteristics of the reducer can be tested, and the versatility is not strong

Even if some test benches can test various dynamic characteristics of the reducer, multiple tooling is required to adjust the test bench and equipment, which is time-consuming and laborious, and it is difficult to control the installation accuracy
