Abstract
The utility model discloses a kind of motor rear end plate, including main cover body, the periphery of the main cover body is uniformly provided with several connection stakes, and the main cover body is provided centrally with shaft hole, the bearing block concentric with shaft hole is provided with the inside of the main cover body；Its main feature is that：Several are provided with the main cover body centered on shaft hole and equally distributed slot, intert in the slot and high heat conduction heat sink is installed.The utility model can guarantee that the concentricity of bearing block and rear end cap, also has very high heat conduction and heat radiation performance, ensures the safe to use of motor, improve the service life of motor.
Description
Technical field
The utility model belongs to technical field of motors, more particularly, to a kind of motor rear end plate.
Background technology
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 for causing motor easily to burn
Condition occurs, and increases cost, and greatly shorten 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 ensures 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, there is provided a kind of motor rear end plate, it
It can guarantee that the concentricity of bearing block and rear end cap, also there is very high heat conduction and heat radiation performance, ensure the safe to use of motor, carry
The service life of high motor.
To achieve these goals, technical solution is used by the utility model：A kind of motor rear end plate, including master
Lid, the periphery of the main cover body are uniformly provided with several connection stakes, and the main cover body is provided centrally with shaft hole, institute
State and the bearing block concentric with shaft hole is provided with the inside of main cover body；Be provided with the main cover body several using shaft hole as
Center and equally distributed slot, intert in the slot and are provided with high heat conduction heat sink.
Horizontal and vertical screw hole is respectively arranged with the connection stake.
The high heat conduction heat sink is conductive graphite piece.
With the above structure, the utility model is compared to the prior art advantageously：The utility model bearing
Seat and rear end cap are an entirety, it is not necessary to are assembled, concentric when can so ensure bearing block with rear end cap shaft hole machined, side
Civilian dress is matched somebody with somebody；Slot is set on rear end cap, and interts high heat conduction heat sink in slot, high heat conduction heat sink 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.
Brief description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the sectional view of the utility model.
Embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
Enclose, the utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 2：A kind of motor rear end plate, including main cover body 1, the periphery of the main cover body 1
Several connection stakes 2 are uniformly provided with, the main cover body 1 is provided centrally with shaft hole 3, and the inner side of the main cover body 1 is set
It is equipped with the bearing block 4 concentric with shaft hole 3；Several are provided with the main cover body 1 centered on shaft hole 3 and is uniformly divided
The slot 5 of cloth, interts in the slot 5 and is provided with high heat conduction heat sink 6.
It is described connection stake 2 on be respectively arranged with horizontal and vertical screw hole, facilitate rear end cap and main case installation and
The installation of fan housing.
Preferably, the high heat conduction heat sink 6 is conductive graphite piece, heat conductivity graphite material (Thermal Flexible
Graphite sheet) chemical composition be mainly single carbon (C) element, be a kind of native element metal mineral film producing high-molecular
Compound.
The utility model bearing block 4 and rear end cap be an entirety, it is not necessary to assemble, can so ensure bearing block 4 and
Rear end cap shaft hole 3 is concentric when processing, convenient for assembly；Carry and slot 5 is set on rear end cap, and intert high heat conduction in slot 5 and dissipate
Backing 6, high heat conduction heat sink 6 can enter the gap cavity in motor, can effectively absorb the high temperature in motor, and high temperature is passed
Lead and distribute to outside machine cavity, perfect heat-dissipating, ensures the safe to use of motor, improves the service life of motor.
