It asks.Motor is the power source of high-speed railway operation, and the requirement of performance indexes is very stringent, and electric motor end cap is as motor
Main load component, need enough strength and stiffness, however the strength and stiffness of current electric motor end cap are difficult to reach
To expected standard, bearing capacity is insufficient.Therefore, it should the new technical solution of one kind be provided and solved the above problems.
Summary of the invention
Deficiency in view of the prior art, the utility model provide a kind of structurally reasonable, good high-speed iron of using effect
Rail power motor end cap.
Realize above-mentioned purpose, the technical solution adopted in the utility model is: high speed rail power motor end cap, the end cap
For rectangular end cap comprising connection when with the inner face that electric machine casing is in contact and the outer end face opposite with inner face,
The cyclic annular heavy platform portion for being centrally formed with indent of the end cap, heavy platform portion center are equipped with the bearing block for inserting bearing block
Mounting hole, the edge of the inner face of the end cap, being circumferentially successively intervally arranged along it has multiple heat release holes, and the four of the inner face
Mounting hole is also provided on a angle, the periphery of the bearing block mounting hole, being circumferentially successively intervally arranged along it has a plurality of radial reinforcement
Muscle.
Further technical solution: the top of the end cap is equipped with the reinforcement block protruded to the outer end face of end cap.
It states that radial reinforcing rib is convex, is formed between the bearing block mounting hole and the inner ring in heavy platform portion, and it is horizontal
Section is in arc-shaped.
The top of the end cap is equipped with several and extends to the oilhole of end cap inner wall.
The outer ring in the ring-type heavy platform portion is equipped at intervals with several convex blocks along its circumferencial direction.
It is cylindrical to state oilhole.
Compared with prior art, the utility model provides a kind of high speed rail power motor end cap, has following beneficial
Effect:
1, the high speed rail power motor end cap of the utility model, it is structurally reasonable, the periphery setting of bearing block mounting hole
Radial reinforcing rib can increase the stiffness and strength of bearing block mounting hole, and the reinforcement block of end cap top setting can be on the whole
The deformation resistance and bearing capacity when electric motor end cap uses are improved, to be applicable in the demand of high speed rail power motor.
2, the high speed rail power motor end cap of the utility model, the edge of the inner face of end cap, between it is circumferential successively
Every being placed with multiple heat release holes, keep its heat dissipation effect preferable, effectively avoiding electric motor end cap, it because being heated for a long time occurs being broken
Phenomenon occurs.
