The outer diameter of upper annular flange is more than the width of mounting hole；The rubber pad lower face is equipped with the lower annular flange of all convexes, after
The screw thread hole surface of end cap is equipped with the mounting groove of the lower annular flange of cooperation, and the thickness of lower annular flange is more than the depth of mounting groove；
Inner annular flange is equipped at the top of the endoporus of the rubber pad, the body of rod of the bolt and the head junction of bolt are equipped with withdrawing
Slot, inner annular flange axial limiting is in escape.
By using above-mentioned technical proposal, after assembling, upper annular flange is pressed in fan housing outer wall and bolt head bottom
Between face, lower annular flange is more than the depth of mounting groove due to thickness, is pressed in mounting groove by fan housing inner wall, avoids wind
Cover is directly contacted with rear end cap, reduces vibrations and the generation of noise, while is avoided the inflow of the liquid such as water and caused screw with after
End cap threaded hole generates corrosion, and since the elasticity of itself can provide pretightning force for bolt, prevents bolt looseness；Upper convex annular
Edge can protect fan housing appearance simultaneously, avoid being scratched by bolt.
Preferably, the outer diameter of the lower annular flange is more than the width of mounting hole and less than the outer diameter of upper annular flange.
By using above-mentioned technical proposal, lower annular flange is more than mounting hole, in non-assembled state constantly, rubber due to outer diameter
The lower annular flange of rubber cushion is stuck on the inside of fan housing, while again since inner annular flange is stuck in escape so that fan housing, bolt,
Rubber pad three becomes integration, the problem of reducing the fittings losts such as bolt.
Preferably, the mounting hole is kidney-shaped.
It is convenient for assembly by using above-mentioned technical proposal.
Preferably, the mounting groove is axial U-shaped structure, and installation channel opening is unanimously towards rear end cap outer end face.
By using above-mentioned technical proposal, after the body of rod of bolt is detached from the cooperation with threaded hole, fan housing, screw and sealing
Pad is whole axially to be exited along motor by the U-lag of rear end cap.

Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-5：
A kind of motor fan cover mounting structure including rear end cap 6, covers on fan housing 2 on rear end cap 6, is set on the rear end cap 6
There is threaded hole 6a, the fan housing 2 is equipped with mounting hole 5, is connected between fan housing 2 and rear end cap 6 by bolt 3, the bolt 3
Rubber pad 4 is arranged on body of rod 3a；4 upper surface of rubber pad is equipped with the upper annular flange 4a of all convexes, upper annular flange
The outer diameter of 4a is more than the width of mounting hole 5；4 lower face of rubber pad is equipped with the lower annular flange 4b of all convexes, rear end cap 6
Threaded hole 6a surfaces be equipped with the mounting groove 6b of the lower annular flange 4b of cooperation, the thickness of lower annular flange 4b is more than mounting groove 6b's
Depth；Inner annular flange 4c, the body of rod 3a of the bolt 3 and the head 3c of bolt 3 are equipped at the top of the endoporus of the rubber pad 4
Junction is equipped with escape 3b, and inner annular flange 4c axial limitings are in escape 3b.
So set, after assembling, upper annular flange 4a be pressed in 2 outer wall of fan housing and 3 head 3c bottom surfaces of bolt it
Between, lower annular flange 4b is more than the depth of mounting groove 6b due to thickness, is pressed in mounting groove 6b, avoids by 2 inner wall of fan housing
Fan housing 2 is directly contacted with rear end cap 6, reduces vibrations and the generation of noise, while is avoided the inflow of the liquid such as water and caused spiral shell
Nail generates corrosion with 6 threaded hole 6a of rear end cap, and since the elasticity of itself can be that bolt 3 provides pretightning force, prevents 3 pine of bolt
It is dynamic；Upper annular flange 4a can protect 2 appearance of fan housing simultaneously, avoid being scratched by bolt 3.
With reference to Fig. 2 and Fig. 5, the outer diameter of the lower annular flange 4b is more than the width of mounting hole 5 and less than upper annular flange
The outer diameter of 4a.So set, lower annular flange 4b is more than mounting hole 5, in non-assembled state constantly, rubber pad 4 due to outer diameter
Lower annular flange 4b is stuck in 2 inside of fan housing, while again since inner annular flange 4c is stuck in escape 3b so that fan housing 2, bolt
3rd, 4 three of rubber pad becomes integration, the problem of reducing 3 grade fittings losts of bolt.Wherein, the mounting hole 5 is kidney-shaped, with
It is convenient for assembly.
Specific to see that Fig. 2, the mounting groove 6b are axial U-shaped structure, mounting groove 6b is open unanimously towards 6 outer end of rear end cap
Face.So set, after the body of rod 3a of bolt 3 is detached from the cooperation of threaded hole 6a, fan housing 2, screw and gasket integrally can be with
It is axially exited along motor by the U-lag of rear end cap 6.
With reference to Fig. 3, the rear end cap 6 sets axial pilot hole 8, sets to connect electric machine casing 1 in pilot hole 8
Long bolt 7.
