Harmonic reducer torsion experimental testing device

Abstract

The invention discloses a harmonic reducer torsion experimental test device. The harmonic reducer torsion experimental test device comprises a harmonic reducer; the harmonic reducer torsion experimental test device further comprises a first static loading device, a second static loading device, a test bed, an output end torsion arm, a first vibration table, a second vibration table, a first excitation rod, a second excitation rod, a laser displacement sensor, a harmonic reducer fixing clamp, a power amplifier, a data acquisition and analysis instrument, a tension line, a weight, a force sensor, an input end fixing connecting piece and an input end fixing cover. According to the harmonic reducer torsion experimental test device, two-side force loading is adopted in the form of a couple, sothat the measuring system only generates a pure rotating effect; during static torsion testing, the weight is put into a weight disc; gravity is converted into tension through the static loading devices, so that a static torsion load can be applied to the output end of the harmonic reducer; during dynamic torsion testing, a circuit is connected, the system is started, parameters are set, a voltageis regulated, the vibration tables are started, and a dynamic torsion load can be applied to the output end of the harmonic reducer.

Description

technical field [0001] The invention relates to a torsion test device for a harmonic reducer. Background technique [0002] Harmonic reducers are the core components of industrial robots. The torsional stiffness of the harmonic reducer will directly affect the positioning control accuracy of the industrial robot, and it is also one of the indicators for evaluating the key performance of the harmonic reducer. Therefore, the study of the torsional stiffness of the harmonic reducer has great application value for the design of the harmonic reducer. Therefore, the research on the torsion test of the harmonic reducer is particularly important. According to literature review, there are many devices for static torsion testing of harmonic reducers, but there are relatively few materials related to dynamic impact torsion testing devices, so it is necessary to design a device with dynamic impact torsion testing.
