BENCH FOR CALIBRATING ELECTRIC DRIVE

FIELD: testing engineering. ^ SUBSTANCE: bench comprises base, driving shaft mounted on the base for permitting rotation, clutch connected with the driving shaft, mechanism for clutch engagement and disengagement, and control desk. The driving shaft is composed of at least two members. One member can be connected with the driving shaft of the electric drive to be tested and is provided with clutch member rigidly connected with its free end, drum with slots uniformly arranged over periphery along the generatrices and mounted on the intermediate section of the shaft, and inductive contactless switch which is mounted on the base near the drum at the level of slots and whose output is connected with the control desk. The other member of the driving shaft provided with the other clutch member kinematically connected with the mechanism for clutch engagement and disengagement is provided with a single-arm lever whose one end is rigidly connected with the shaft member for permitting rotation together with it and co-operation with the force pickup with its free end. ^ EFFECT: simplified design and expanded functional capabilities of the bench. ^ 1 dwg
