Abstract
The invention discloses an input fixing structure of harmonic reducer comprehensive performance test equipment. Two input fixing disks need to be installed when the input end of the harmonic reducer to be detected is fixed, so that a good fixing effect is achieved. The input fixing disc is fixed on the connecting and positioning sleeve through an outer ring mounting hole and is fixed on the flange end face of the input shaft of the speed reducer through an inner ring mounting hole, so that the input end is fixed. In order to avoid the direct contact between the input fixed disk and the tested harmonic reducer and damage to the tested harmonic reducer, a gasket is added between the input fixed disk and the tested harmonic reducer for protection.
