One end of the stretching motor rear end plate of axle, the outer surface of motor casing provided with multiple tracks along motor reel it is axially extending between
Formed between the radiating ribs of arrangement, adjacent two radiating ribs and a fan guard, motor running are also covered with outside distinguished and admirable road, fan
When, fan is rotated, and air enters from the air admission hole of fan guard, powerful air-flow is formed through passing through fan, the air-flow formed is in wind
Fan under the gathering of cover along the wind flow passage between each radiating ribs, so as to walk the major part on motor casing by convective zone
Heat, reaches the purpose of cooling.
Although the ventilated motor of said structure can be cooled down to motor casing, for motor drive end bearing bracket
Cooling effect but very little because motor drive end bearing bracket is unsuitable for setting radiating ribs on surface, therefore airflow passes are electronic
During the outer surface of machine drive end bearing bracket, seldom heat can only be taken away, cause cooling effect it is not good, influence operation, especially when electronic
Machine drive end bearing bracket and other parts, when such as pump is connected, motor drive end bearing bracket, the connection end of pump can produce substantial amounts of heat, it is necessary to and
When cool down.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of to casing and drive end bearing bracket all with preferable cooling effect
Drive end bearing bracket is provided with the ventilated motor of heat emission hole.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：Drive end bearing bracket is provided with the air-cooled electricity of heat emission hole
Motivation, including casing, motor reel, drive end bearing bracket, rear end cap, fan and fan guard, the drive end bearing bracket are arranged on the casing
Front end, the rear end cap be arranged on the casing rear end, the motor reel is sleeved in the casing, and the electricity
The rear end cap is stretched out in the rear end of motivation axle, and the fan is arranged on the rear end of the motor reel, the outer surface of the casing
Form distinguished and admirable between axially extending spaced apart radiating ribs provided with multiple tracks along the motor reel, adjacent two radiating ribs
Road, the fan guard is covered on outside the fan, and the edge of the rear end face of the drive end bearing bracket outwards exceeds before the casing
The edge of end face, the drive end bearing bracket is provided with more than one heat emission hole, one end of the heat emission hole extend to it is described before
The rear end face of end cap, and the distinguished and admirable road led between adjacent two radiating ribs, the other end of the heat emission hole extend to it is described before
The front end face of end cap.
Further, axis direction of the heat emission hole from back to front towards the drive end bearing bracket is tilted.
Beneficial effects of the present invention are：The present invention is simple in construction, it is small that existing equipment is changed, be easily achieved；The present invention by
In being provided with heat emission hole on drive end bearing bracket, therefore, when the distinguished and admirable road between air-flow passes through each radiating ribs arrives at drive end bearing bracket, air-flow
It will flow into heat emission hole, and most of heat on drive end bearing bracket is taken away when flowing out heat emission hole, and reach the purpose of cooling drive end bearing bracket,
And the last air-flow flowed out from heat emission hole flows through the connection end further from the part being connected with drive end bearing bracket, so as to take away this
Heat on the connection end of part, therefore the connection end of the invention to casing, drive end bearing bracket and the part being connected with drive end bearing bracket is all
With preferable cooling effect.
