When enclosing elastic force, it may appear that the forward and backward movement of shaft is out of control, the phenomenon that axial float, long-time service is present with diastema, Wu Faman occurs
Sufficient high-precision grinding needs or even is present with the appearance of shaft stuck phenomena such as can not working.
The radiator that conventional motors are set in itself is generally radiating ribs and leaf fan on casing, but motor is in reality
Border in use, easily cause electric motor overheating due to the use of overlong time, heat dissipation not in time, the feelings that motor is caused easily to burn
Condition occurs, and increases cost, and greatly shortens the service life of motor.
Motor rear end plate top chock and end cap generally require assembling, and when processing easily loosens, it is impossible to ensure bearing block
With the concentricity of end cap, when assembling, can cause rotor to rotate in generator to have some setbacks, rotor and stator locking when serious.
The content of the invention
The purpose of this utility model is in view of the deficiency of the prior art, it is electronic to provide a kind of high heat conduction heat dissipation
Machine, it can guarantee the concentricity of bearing block and rear end cap with that can eliminate axial float, also have very high heat conduction and heat radiation
Can, the characteristics of ensureing the safe to use of motor, improve the service life of motor.
To achieve these goals, technical solution is used by the utility model：A kind of high heat conduction radiation electromotor, bag
It includes shaft, the rotor in shaft, motor casing, the stator in motor casing and is installed on motor casing rear and front end
Drive end bearing bracket and rear end cap, the shaft and rotor are mounted in motor casing and drive end bearing bracket is stretched out with after in the both ends of the shaft
Outside end cap, the shaft is connected with drive end bearing bracket by fore bearing, and the shaft is connected with rear end cap by rear bearing,
The part that the shaft is stretched out outside rear end cap is fixed with fan, and the inside of the drive end bearing bracket is equipped with pressing plate by screw Guan County,
The pressing plate has the flange part that a circle is resisted against front axle bearing outer-ring；The rear end cap is provided centrally with shaft hole, described
The bearing block concentric with shaft hole is provided on the inside of rear end cap, several are provided on the rear end cap using shaft hole in
The heart and equally distributed slot intert in the slot and are equipped with high heat conduction cooling fin.
The periphery of the rear end cap be uniformly provided with several connection stake, it is described connection stake on be respectively arranged with laterally and
Vertical screw hole.
The high heat conduction cooling fin is conductive graphite piece.
With the above structure, the utility model is compared to the prior art advantageously：The utility model bearing
Seat is an entirety with rear end cap, need not be assembled, concentric when can so ensure bearing block with rear end cap shaft hole machined, side
Civilian dress is matched somebody with somebody；Slot on rear end cap is set, and interts high heat conduction cooling fin in slot, high heat conduction cooling fin can enter in motor
Gap cavity, can effectively absorb the high temperature in motor, and high temperature conduction is distributed to outside machine cavity, perfect heat-dissipating,
Ensure the safe to use of motor, improve the service life of motor；The setting of pressing plate can eliminate axial float.
