Fan for motor and manufacturing method of fan

Abstract

The invention discloses a fan for a motor and a manufacturing method of the fan. The fan comprises a base disc, a reinforcing disc and fan blades mounted on the base disc. The reinforcing disc is connected with a shaft barrel, a clamping hoop is arranged between the base disc and the reinforcing disc, the clamping hoop comprises an upper hoop and a lower hoop, and the upper hoop and the lower hoop are clamped and fixed through bolts and nuts; clamping blocks are arranged on the inner side of the upper hoop and the inner side of the lower hoop, clamping holes are formed in the shaft barrel, the clamping blocks are matched with the clamping holes, the clamping blocks of the upper hoop and the lower hoop are inserted into the shaft barrel through the clamping holes to clamp a motor shaft in the shaft barrel, and the distance between the upper hoop and the lower hoop is adjusted through bolts and nuts. The fan and a rotating shaft are fixed through the clamping hoop, on the one hand, the stability of connection between the fan and the rotating shaft is conveniently improved, the effect of firm connection is achieved, and the problem of collision displacement or connection disengagement is solved; and on the other hand, the clamping inner diameter of the clamping hoop is adjustable, the clamping hoop can adapt to rotating shafts with different diameters and different shapes, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a motor fan and a manufacturing method thereof. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque. Motors are divided into DC motors and AC motors according to the power used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The w...
