The utility model provides a rotor, heat dissipation stability is good.
Description
Technical Field
The utility model relates to an electric machine technology especially relates to a motor rotor's of system fan blade technique is moulded in area.
Background
The alternating current asynchronous motor is mainly characterized in that the heat dissipation fan blades are arranged at the tail end of the rotor and are usually molded, the heat dissipation fan blades are arranged at the tail end of the rotor through a molding key and a key groove of the rotor in a matching mode, the molding key of the heat dissipation fan blades is easy to soften due to the fact that the size of the molding key is small, after the motor runs for a long time, the heat on the rotor can easily cause the softening phenomenon of the molding key of the heat dissipation fan blades, and after the softening phenomenon to a certain degree, the softening phenomenon can not offset the wind resistance caused by the fact that the rotor drives the heat dissipation fan blades to rotate, so that deformation is caused.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that an electric motor rotor of system fan blade is moulded in area that heat radiation stability is good is provided.
In order to solve the technical problem, the utility model provides a motor rotor with plastic blades, which comprises a motor rotating shaft, heat dissipation blades and a rotor iron core fixed on the motor rotating shaft;
the fan blade seat is sleeved at the rear end of the motor rotating shaft, an assembly key is formed on the fan blade seat, and the assembly key on the fan blade seat is clamped in the fan blade key groove at the rear end of the motor rotating shaft, so that the fan blade seat and the motor rotating shaft are mutually locked in the circumferential direction of the motor rotating shaft;
the method is characterized in that: the fan blade is characterized in that a plurality of auxiliary clamping grooves symmetrically distributed around the motor rotating shaft are formed in the fan blade seat, a detachable fan blade buckle is fixed at the rear end of the motor rotating shaft, a plurality of clamping jaws symmetrically distributed around the motor rotating shaft are formed in the fan blade buckle, and each clamping jaw on the fan blade buckle is clamped into each auxiliary clamping groove on the fan blade seat in a tight fit mode.
The utility model provides a take electric motor rotor of moulding fan blade, it is rotatory to utilize the jack catch on assembly key on the fan blade seat and the fan blade buckle to drive the heat dissipation fan blade together, still can ensure through the fan blade buckle that the heat dissipation fan blade keeps rotatory under the condition of the soft inefficacy of assembly key on the fan blade seat to ensure that the heat dissipation fan blade can be stable provide radiating wind-force for the motor, have the good characteristics of heat dissipation stability.

Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1-5, an embodiment of the present invention provides a motor rotor with plastic blades, which includes a motor shaft 1, heat dissipation blades 3, and a rotor core 2 fixed on the motor shaft;
the heat dissipation fan blade is characterized in that a fan blade key groove 11 is formed in the peripheral face of the rear end of the motor rotating shaft 1, the heat dissipation fan blade is composed of an annular fan blade seat 31 and a plurality of fan blades 32 fixed on the fan blade seat, the fan blade seat 31 is sleeved at the rear end of the motor rotating shaft 1, an assembly key 33 is formed on the fan blade seat 31, and the assembly key 33 on the fan blade seat is clamped into the fan blade key groove 11 at the rear end of the motor rotating shaft, so that the fan blade seat 31 and the motor rotating shaft 1 are locked with each other in the circumferential direction of the motor rotating shaft;
the method is characterized in that: the fan blade seat 31 is provided with a plurality of auxiliary clamping grooves 34 symmetrically distributed around the motor rotating shaft, the rear end of the motor rotating shaft is fixed with a detachable fan blade buckle 4, a plurality of clamping claws 41 symmetrically distributed around the motor rotating shaft are formed on the fan blade buckle 4, and the clamping claws 41 on the fan blade buckle are respectively clamped into the auxiliary clamping grooves 34 on the fan blade seat 31 in a tight fit mode.
The embodiment of the utility model provides an at work, the jack catch on motor shaft passes through the assembly key on the fan blade seat and the fan blade buckle drives the heat dissipation fan blade together rotatory, when motor shaft's high temperature and lead to the assembly key on the fan blade seat (great with motor shaft area of contact) to take place to soften, the jack catch on the fan blade buckle still can transmit motor shaft's revolving force for the heat dissipation fan blade to ensure that the heat dissipation fan blade can overcome the windage and keep rotatory, provide radiating wind-force for the motor.
