Abstract

The invention discloses a rotor axial gap adjusting method for an auto cooling fan motor. The gap adjusting method comprises the steps of firstly measuring the axial gap of the rotor of the motor, thus obtaining a real-time measurement result; then jacking the front end cover of a jacking motor by using a jacking block to deform the front end cover, thus generating an axial displacement; measuring after adjustment is completed, and if qualified, completing the adjustment; if not qualified, adjusting in the same way to allow the axial gap to be qualified; and if not qualified either, scraping the motor. Therefore, the gap adjusting method does not need to add the spacer, and is simple to operate, capable of achieving automation, more accurate in gap adjustment, and thus applicable to adjusting the gaps of a large scale of motors, and thereby the axial gap of each motor can be adjusted before leaving the factory, and the whole quality stability of the products is greatly improved.

Description

technical field [0001] The invention relates to a method for adjusting the axial gap of a rotor of an automobile cooling fan motor, and is also applicable to the adjustment of the axial gap of rotors of other motors. 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 a commutator on which sl...
