Parallel-shaft output reducer bending rigidity testing system

Abstract

The invention provides a parallel-shaft output reducer bending rigidity testing system, and relates to the technical field of mechanical transmission. The parallel-shaft output reducer bending rigidity testing system comprises a test board, a test piece, a loading system, a pressure sensor and a displacement detection assembly. The test board is used for fixedly installing the reducer. The test piece can be fixed with the output end of the reducer. At the moment, the loading system can push the test piece to enable the test piece and the output end of the reducer to slightly swing. The pressure sensor is used for detecting the pressure between the test piece and the loading system, and the pressure at the moment is the radial force applied to swing of the test piece by the loading system.The displacement detection assembly is used for detecting the displacement variation 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] The bending stiffness is an important indicator of the performance of the parallel shaft output reducer, and it has an important influence 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 by a counterweight, and the dial indicator reads the deflection of the output shaft under the load, and then obtains the bending stiffness value of the reducer. The method load is added discretely, 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 discrete load adding o...

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 discrete load addition operation is cumbersome, time-consuming and laborious. Low efficiency; the recording of test results and numerical processing are also relatively cumbersome
