SUMMERY OF THE UTILITY MODEL

Utility model purpose: to the problem and not enough of existence among the above-mentioned prior art, the utility model aims at providing a can strengthen radiating effect's motor rear end cap.

The technical scheme is as follows: in order to achieve the above object, a can strengthen radiating effect's motor rear end cap, comprising a cover body, the inboard of lid is equipped with the concave edge of round, the inboard of lid is located and is equipped with a plurality of louvres, the inboard of lid is close to concave edge department and is equipped with the arc fin, be equipped with square through hole on the arc fin, the inboard intermediate position of lid sets up the bearing sleeve.

Furthermore, a first column body and a second column body are arranged on the outer side of the cover body. The first column body and the second column body are designed to be convenient for workers to carry, install or disassemble.

Furthermore, the outer edge of the cover body is provided with a narrow convex edge and a wide convex edge, a first notch and a second notch are arranged on the inner edge and the outer edge of the narrow convex edge, the first notch is positioned on the inner edge of the narrow convex edge, and the second notch is positioned on the outer edge of the narrow convex edge; and a second notch is formed in the outer edge of the wide convex edge. The notch is designed to allow the cover to be removed from the motor or installed using a tool.

Further, one end of the bearing sleeve protrudes out of the inner surface of the cover body, and the other end of the bearing sleeve is flush with the outer surface of the cover body.

Further, the outer ring of the bearing sleeve is provided with a plurality of heat dissipation ribs, and the heat dissipation ribs are obliquely arranged.

Furthermore, an arc-shaped flange is arranged on the heat dissipation rib. The arc-shaped flange increases the heat dissipation area of the heat dissipation rib and enhances the heat dissipation effect.

Furthermore, a limiting clamping ring is arranged at the joint of the bearing sleeve and the inner side of the cover body. The connection tightness of the bearing sleeve and the cover body can be ensured by the limiting clamping ring.

Above-mentioned technical scheme can find out, this practical beneficial effect does:

a can strengthen radiating effect's motor rear end cap, structural design is simple, can realize zonulae occludens with motor body, is equipped with louvre and arc fin on the lid, under the more condition of long heat than the motor live time, the heat that the louvre produced the motor dispels the heat in time, the radiating effect is good, the arc fin fully absorbs the heat to give off the heat through the quad slit, can also prevent effectively that the dust from getting into the probability of motor.
