[0003] For similar speed reducers, factory testing or trials are usually inconvenient to install and difficult to load. Utility Model Content

[0004] This utility model addresses the problem that cross-shaft reducers are often inconvenient to install and difficult to load during factory testing or inspection. It provides a loading test device for cross-shaft reducers, which structurally transforms the spatial arrangement of the input shaft direction and the output shaft direction from an intersecting form at a certain angle to a parallel form. Functionally, it eliminates the loading difficulties caused by changes in the speed ratio of the reducer itself.

The other end of the cross slider is connected to one end of torque transmission bearing housing two. The other end of torque transmission bearing housing two is connected to the reducer under test at the loading end via a flange connecting plate assembly.

[0011] Furthermore, the driving end and the loading end are arranged symmetrically.

[0012] Furthermore, a drive-end protective bearing housing is provided between the drive-end torque sensor and the drive-end measured reducer.
