Rotor aluminum casting structure of outer rotor motor

Abstract

The invention relates to the technical field of outer rotor motors, and particularly relates to a rotor aluminum casting structure of an outer rotor motor. The rotor aluminum casting structure comprises an injection mold main body, a rotor core is fixedly arranged in the injection mold main body, a plurality of liquid circulation holes are formed in the circumferential direction of the rotor core,the liquid circulation holes are arranged along the axial direction of the rotor core, a waterproof ring is arranged on one side of the rotor core, the waterproof ring is fixed in the injection moldmain body, a rotating shaft is coaxially arranged in the rotor core, a shaft seat is fixedly sleeved at the tail of the rotating shaft, the shaft seat is fixed in the injection mold main body, and therotor core, the waterproof ring, the shaft seat and the rotating shaft are packaged together through injection molding equipment to form a plastic package main body. The rotor aluminum casting structure provided by the invention effectively eliminates the assembly error caused by the conversion, and effectively solves the problem of the circular rotation of the rotating shaft, and as the rotor core, the waterproof ring, the shaft seat and the rotating shaft are packaged together, the problem of concentricity of the rotating shaft with the plastic package main body and the rotor core is effectively solved, and the service life of the motor is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of outer rotor motors, in particular to a cast aluminum rotor structure of an outer rotor motor. Background technique [0002] There are components such as rotor core, bearing and rotating shaft on the outer rotor motor body. There are errors in the processing of each part, and there are also assembly errors in the assembly of parts. Due to the errors existing in the parts and assembly process, cumulative errors will be generated after assembly. Due to the existence of cumulative errors, the bearings and shafts will run out of circles during operation, which will affect the service life of the bearings and the operating life of the motor. To sum up, solve the cumulative error The problem of error appears to be particularly important. Contents of the invention [0003] The object of the present invention is to solve the shortcoming of accumulative assembling error in the outer rotor motor in the prior art,...
