Abstract
The application provides a novel electric motor rotor axle, including the middle part with middle part interference fit's tip, middle part and tip have the cavity of mutual intercommunication, the joint guide plate in the cavity at middle part, the guide plate is followed the axis direction at middle part is helical structure, the tip be equipped with the through-hole of the cavity intercommunication of tip. When the motor rotor operates, the guide plate of the spiral structure can rotate synchronously, spiral airflow is formed in the cavities of the middle part and the end part, air flows in from one end of the rotor shaft and flows out from the other end, heat is taken out, and therefore heat dissipation and cooling of the motor rotor are achieved.
Description
Technical Field
The application relates to the technical field of motors, in particular to a novel motor rotor shaft.
Background
The motor rotor can generate a heating phenomenon in the operation process, and the heat dissipation part can thoroughly influence the service life of the rotor.
Therefore, how to provide a rotor capable of efficiently dissipating heat is an important technical problem that needs to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned technical problem, this application provides a novel electric motor rotor axle, including the middle part with middle part interference fit's tip, middle part and tip have the cavity of mutual intercommunication, the joint guide plate in the cavity at middle part, the guide plate is followed the axis direction at middle part is helical structure, the tip be equipped with the through-hole of the cavity intercommunication of tip.
Optionally, the two ends of the middle part are provided with clamping grooves, and the end parts are clamped in the clamping grooves.
Optionally, both ends of the baffle abut against the ends.
Optionally, the diameter of the baffle is equal to the diameter of the cavity in the middle portion.
Optionally, the surface of the baffle is smooth.
Optionally, the through holes are evenly arranged on the end portion.
Use the technical scheme of this application, at electric motor rotor operation during operation, helical structure's guide plate can rotate in step, forms the spiral air current in the cavity of middle part and tip, makes the air flow in and flow out from the other end from the one end of rotor shaft to take the heat away, thereby realize the heat dissipation cooling to electric motor rotor.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present application.
Detailed Description
As shown in fig. 1, the embodiment of the application provides a novel electric motor rotor shaft, including the middle part 1 of cylindrical structure with two tip 4 of middle part interference fit, two tip 4 symmetries set up, the cavity 2 of middle part 1 with the cavity 5 of tip 4 communicates each other, the both ends of middle part 1 are equipped with draw-in groove 3, tip 4 joint is in the draw-in groove 3, joint guide plate 7 in the cavity 2 of middle part 1, guide plate 7 follows the axis direction of middle part 1 is helical structure, tip 4 be equipped with the through-hole 6 of the cavity 5 intercommunication of tip 4, the both ends butt of guide plate 7 is in on tip 4, and the diameter of guide plate 7 equals the diameter of the cavity 2 of middle part 1, the surface of guide plate 7 is smooth, and through-hole 6 is in evenly arranged on tip 4.
In this embodiment, guide plate 7 joint is in cavity 2 of middle part 1, guarantees that guide plate 7 can not be at the 2 internal rotations of cavity, under the limiting displacement of two tip 4, guarantees that guide plate 7 can not be axial slip in cavity 2, and guide plate 7 can be along with middle part 1 synchronous rotation.
During operation, when the motor rotor operates, the guide plate of the spiral structure can rotate synchronously, spiral airflow is formed in the cavities of the middle part and the end part, air flows in from one end of the rotor shaft and flows out from the other end, heat is taken out, and therefore heat dissipation and cooling of the motor rotor are achieved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
