Abstract
The invention discloses a high-strength fan connection structure which comprises a fan body made of an aluminum alloy and fan blades, wherein the fan blades are uniformly distributed on the fan body along the circumferential direction, and the fan blades and the fan body are formed into a whole; the middle of the fan body is provided with a shaft sleeve; a lining which is made of alloy steel is fixedly connected in an inner hole of the shaft sleeve; the lining is internally provided with a hole which is connected with a motor shaft. Further improvements of the high-strength fan connection structure are as follows: the inner hole of the shaft sleeve is internally provided with a toroidal groove; a toroidal crossette which is arranged at the outer wall of the lining is embedded into the toroidal groove of the inner hole of the shaft sleeve. By virtue of the high-strength fan connection structure, the structural strength at the joint between the high-strength fan connection structure and the motor shaft is significantly improved.
Description
Technical field
The present invention relates to technical field of motors, be specifically related to high strength fan connecting structure.
Background technique
Motor produces certain heat in operation process, is provided with fan with heat radiation in motor.The fan body having a kind of aluminum alloy to make in existing motor ventilating fan, the motor ventilating fan of flabellum integration, be provided with axle sleeve in the middle of fan body, is provided with Kong Yiyu motor shaft and connects in axle sleeve.This motor ventilating fan is lightweight, but finds in Long-Time Service process, and axle sleeve content is yielding, affects the normal use of motor ventilating fan.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high strength fan connecting structure with the structural strength of motor shaft joint that can significantly improve.
The present invention is achieved through the following technical solutions technical goal.
High strength fan connecting structure, comprises fan body, flabellum that aluminum alloy is made; Described flabellum is along the circumferential direction distributed on fan body, and forms an entirety with fan body; Axle sleeve is provided with in the middle of described fan body; Its improvements are: described inner hole of shaft sleeve internal fixtion connects the lining that alloyed steel is made; The hole be connected with motor shaft is provided with in described lining.
In said structure, described inner hole of shaft sleeve is provided with circumferential groove, and liner outer wall is provided with hoop convex shoulder; Described liner outer wall hoop convex shoulder embeds in inner hole of shaft sleeve circumferential groove.
The present invention compared with prior art, has following good effect:
1, the present invention fans the lining that inner hole of shaft sleeve internal fixtion connection alloyed steel is made, and significantly improves the structural strength with motor shaft joint.
2, liner outer wall hoop convex shoulder of the present invention embeds in inner hole of shaft sleeve circumferential groove, significantly improves the structural strength with motor shaft joint further.
