Abstract

The invention discloses a rotor clearance adjusting device of an automobile radiator fan motor. The rotor clearance adjusting device comprises a rack, wherein the rack is provided with an operating platform, a lower die is fixed on the operating platform, an inserting hole is formed in the lower die, a jacking block is vertically arranged on the lower die in a sliding manner, a lower sliding seat is vertically arranged on the rack and is positioned at the lower end of the operating platform in the sliding manner, the lower sliding seat is driven by a lower sliding seat lifting power device, and a jacking transmission piece is fixed on the lower sliding seat; an upper sliding seat is vertically arranged on the rack and is positioned above the operating platform in the sliding manner, an upper die matched with the back end cover of the motor is arranged on the upper sliding seat, and the upper sliding seat is driven by an upper sliding seat lifting power device. According to the rotor clearance adjusting device, axial clearance adjustment can be carried out quickly on each motor before factory leaving, so that the accuracy of clearance adjustment is greatly improved, the efficiency is improved, large batch production is easily realized, and the stability of product quality is guaranteed.

Description

technical field [0001] The invention relates to a rotor gap adjustment device, in particular to a rotor gap adjustment device for an automobile radiator fan motor. Background technique [0002] The cooling fan of the vehicle is driven by a motor. This motor has a rotor. The rotor shaft of the rotor is supported by bearings at the front end and the rear end and is installed on the end covers at both ends. The end of the motor rotor shaft extending out of the stator shell is the front end, corresponding to One end of the rotor shaft is the rear end, so the rear end of the rotor shaft is rotatably mounted on the rear end cover, while the front end of the rotor shaft passes through the front end cover and is rotatably mounted on the front end cover through bearings, and the front end cover is clamped and fixed with the stator housing. The rotor has an armature consisting of a coil with an iron core and, for the supply of electric current, a segmented commutator on which sliding ...
