Technical Field

[0001] The utility model relates to the technical field of harmonic reducer test platforms, and particularly relates to a running-in test bench for harmonic reducers. Background Technique

[0002] As a most basic mechanical transmission component, the harmonic reducer is widely used in the high-precision transmission field represented by industrial robots. With a series of characteristics such as small volume, light weight, large transmission ratio, high transmission efficiency, high load-bearing capacity, smooth transmission, and no impact, the harmonic reducer has become the focus of research by domestic and foreign scholars and research institutions.

[0003] The running-in test bench for harmonic reducers is a device used to test the performance of harmonic reducers during operation, including key indicators such as durability, transmission efficiency, noise, and temperature rise. Most of the existing running-in test benches for harmonic reducers are horizontal test platforms in the horizontal direction. When installing the harmonic reducer, it is necessary to insert and install it sequentially from one side to the other side. When replacing the test unit among them, it is necessary to remove it sequentially from the outermost side. The process is slow and cumbersome. Moreover, when moving the equipment, the pushing method is often used, and this adjustment method has low precision. Therefore, the technical personnel in this field provide a running-in test bench for harmonic reducers to solve the problems raised in the above background technique. Content of the Utility Model
