Parallel shaft output reducer bending stiffness test system

Abstract

The invention provides a bending stiffness test system of a parallel shaft output reducer, which relates to the technical field of mechanical transmission. The table is used to fix the reducer, and the test piece can be fixed on the output end of the reducer. At this time, the loading system can push the test piece, so that the test piece and the output end of the reducer both have a slight swing, and the pressure sensor is used to detect The pressure between the test piece and the loading system, the pressure at this time is the radial force that the loading system gives the test piece to swing; the displacement detection component is used to detect the displacement change of the preset position of the test piece when the test piece swings.

Description

technical field

[0001] The invention relates to the technical field of mechanical transmission, in particular to a testing system for the bending stiffness of a parallel shaft output reducer. Background technique

[0002] Bending stiffness is an important indicator of the performance of the parallel shaft output reducer, and it has an important impact on the stiffness of the entire mechanical equipment or transmission system. At present, the performance test of the bending stiffness of the reducer usually adopts a bench test. The output shaft is loaded through the counterweight, and the dial gauge reads the deflection of the output shaft under the load, and then obtains the bending stiffness value of the reducer. This test The addition of the method load is discrete, and the deflection angle of the output shaft under several loads is recorded, and then the fitting curve of the bending stiffness of the reducer is drawn. The test results have large errors. In addition, the dis...
