Description
Technical field
The invention belongs to technical field of motors, more particularly, to a kind of motor rear end plate.
Background technology
The heat abstractor 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 because usage time is long, radiating 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, easily loosen during processing, it is impossible to ensure bearing block
With the axiality of end cap, rotor can be caused to be rotated in generator during assembling and had some setbacks, rotor and stator locking when serious.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the shortcomings of the prior art, there is provided a kind of motor rear end plate, it can be protected
The axiality of bearing block and rear end cap is demonstrate,proved, also there is very high heat conduction and heat radiation performance, ensures the safe to use of motor, improves electricity
The service life of motivation.
To achieve these goals, the technical solution adopted in the present invention is：A kind of motor rear end plate, including main cover
Body, 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, described
The bearing block concentric with shaft hole is provided with the inside of main cover body；Several are provided with the main cover body using shaft hole in
The heart and equally distributed slotted eye, intert in described slotted eye and high heat conduction fin is installed.
Horizontal and vertical screw is respectively arranged with the connection stake.
The high heat conduction fin is conductive graphite piece.
After said structure, the invention has the advantages that compared with the prior art,：Bearing block of the present invention and rear end
Cover as an entirety, it is not necessary to assemble, it is concentric when can so ensure bearing block with rear end cap rotating shaft hole machined, it is convenient for assembly；
Slotted eye is set on rear end cap, and interts high heat conduction fin in slotted eye, the space that high heat conduction fin can enter in motor
Cavity, the high temperature in motor can be effectively absorbed, and high temperature conduction is distributed to outside machine cavity, perfect heat-dissipating, ensure electricity
Motivation it is safe to use, improve the service life of motor.

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 slotted eye 5 of cloth, intert in described slotted eye 5 and high heat conduction fin 6 is installed.
It is described connection stake 2 on be respectively arranged with horizontal and vertical screw, facilitate rear end cap and main case installation and
The installation of fan housing.
Preferably, the high heat conduction fin 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.
Bearing block 4 of the present invention and rear end cap are an entirety, it is not necessary to assemble, can so ensure bearing block 4 and rear end
Lid shaft hole 3 is concentric when processing, convenient for assembly；Carry and slotted eye 5 is set on rear end cap, and intert high heat conduction fin in slotted eye 5
6, the space cavity that high heat conduction fin 6 can enter in motor, the high temperature in motor can be effectively absorbed, and high temperature is conducted and dissipated
It is sent to outside machine cavity, perfect heat-dissipating, ensures the safe to use of motor, improves the service life of motor.
