Technical Field

The utility model relates to motor technical field especially relates to a take electric motor rotor shell of spline.

Background

A motor rotor: also a rotating part in the motor. The motor consists of a rotor and a stator, and is a conversion device for realizing electric energy and mechanical energy and electric energy. The rotor of the motor is divided into a motor rotor and a generator rotor. The motor rotor shell is used for fixing the motor rotor, the rotor shell rotates along with the rotor, the radiating effect can be played inside the motor, the structure of the common motor rotor shell is complex, the fixation between the rotor shell and the rotor is not firm, the phenomenon of slipping easily occurs, and the stable work of the motor is not facilitated.

Therefore, in order to solve the technical problem, it is necessary to improve the existing design, a motor rotor shell with splines is designed, the shell inner ring and the shell outer ring of the motor rotor shell with splines are fixedly connected together through an injection molding connecting ring, the design of the injection molding connecting ring saves the cost, the connection of the bending part of the shell is firmer, the injection molding reinforcing sheet increases the fixing strength of the shell, the center of the shell inner ring is clamped and fixed with the splines, the inner side surface of the splines is provided with a plurality of anti-skidding bulges, the anti-skidding bulges are fixed together with the tight clamping of the motor rotating shaft, and the slipping between the anti-skidding bulges and the motor rotating shaft can be effectively prevented. In addition, this take electric motor rotor shell of spline simple structure, intensity is firm, has good heat dissipation efficiency, is fit for using widely.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a take electric motor rotor shell of spline, includes shell inner circle and shell outer lane, be in the same place through the go-between fixed connection that moulds plastics between shell inner circle and the shell outer lane, be equipped with a plurality of reinforcement pieces of moulding plastics on the go-between of moulding plastics, the reinforcement piece of moulding plastics is fixed in the shell outer lane, be equipped with a plurality of louvres on the shell outer lane, the central chucking of shell inner circle is fixed with the spline, the medial surface of spline is equipped with a plurality of anti-skidding archs.

Preferably, the thickness of the injection-molded reinforcing sheet is greater than that of the outer ring of the shell.

Preferably, the number of the heat dissipation holes is 16.

Preferably, the number of the anti-slip projections is 21.

The utility model relates to a take electric motor rotor shell of spline, through moulding plastics go-between fixed connection together between this take electric motor rotor shell's of spline shell inner circle and the shell outer lane, the design of the go-between of moulding plastics, the cost has been saved promptly, it is more firm to make the connection of the shell department of bending again, the reinforcement piece of moulding plastics has increased the fixed strength of shell, the center chucking of shell inner circle is fixed with the spline, the medial surface of spline is equipped with a plurality of non-slip raised, non-slip raised is together fixed with the inseparable chucking of motor shaft, can prevent effectively that skid from appearing between the two. In addition, this take electric motor rotor shell of spline simple structure, intensity is firm, has good heat dissipation efficiency, is fit for using widely.
