Abstract

The present invention provides a motor shaft with a location pin. The motor shaft comprises a motor shaft body, the motor shaft body is provided with a cut-through through groove, the internal portionof the through hole is in interference fit with is internally provided with a location pin, the length of the location pin is larger than the outer diameter of the motor shaft body, and the motor shaft body is coaxially provided with a thread tightening portion. The motor shaft with a location pin is fixedly connected with a fan blade at the external portion through the location pin and the thread tightening portion to bear a large load, and the phenomenon of failure due to slipping between the motor shaft and the fan blade cannot be generated.

Description

technical field [0001] The invention relates to a motor shaft, in particular to a motor shaft with positioning pins. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to convert mechanical energy into electrical energy to generate drive torque as a power source for electrical appliances or various machines. [0003] At present, the most commonly used is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity. With the maturity of wind power generation technology, wind power is slowly entering our life. Classification of working power sources: It can be divided into DC motors and AC motors. DC motors are motors that rely on DC operating voltage. They are widely used in tape recorders, video recorders, DVD players, electric shavers, hair dryers, electronic watches, toys, etc. According to the type...
