Abstract

The utility model discloses a radiating motor end cover of circumference, structurally, the utility model discloses lie in motor overcoat contact segment, adopt the even fretwork of ellipse to when rotatory with electric motor rotor, produce the circumferential direction air current, spill out from oval hole, thereby realize the air current circulation, further strengthen the radiating effect of motor during operation. The material is reduced to 1/2 of the prior material thickness at the joint of the rotor and the end cover, but the connection hole of the rotor and the end cover is processed by adopting a surrounding type reinforcing rib, so that the use strength of the rotor is ensured to be achieved when the rotor works. The connection part of the motor shell is in an outer wrapping type, so that the motor shell is convenient for daily maintenance. In quality, the strength requirement of the motor in use is ensured, and the weight of the motor is reduced.

Description

Circumferential heat dissipation motor end cover

Technical Field

The utility model relates to an automobile manufacturing technical field especially relates to a radiating motor end cover of circumference.

Background

The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to rotate the motor. Under the severe trend of the current market, the motor manufacturing industry keeps the operation performance of the motor.

The motor end cover is an important component of the motor, is arranged at the rear end of the motor and is directly connected with a motor rotor, most of the motor end covers are finished by adopting solid casting, the weight of the motor is increased, and the rear end does not have the functions of airflow flowing and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the motor end cover quality that the above expounded is heavy, can not realize the circulation of rear end air current, does not have the heat dissipation scheduling problem, and provides a circumference radiating motor end cover.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a circumferential heat-radiating motor end cover comprises a connecting hole (1), an inner connecting platform (2), an airflow circulating hole (3), a fixing lug (4), a rotor suspension connecting hole (5), a surrounding type reinforcing rib (6), a fixing end (7) and a suspension type hollow hole (8);

the inner connecting table (2) is arranged on one side, connected with the motor shell, of the end cover, three fixed ends (7) are uniformly arranged on the outer side of the inner connecting table (2), and a connecting hole (1) is formed in each fixed end (7); hollow airflow circulation holes (3) which are distributed at equal intervals are arranged below the inner connecting table (2); the axial line of the end cover is provided with a rotor suspension connecting hole (5), the periphery of the rotor suspension connecting hole (5) is provided with surrounding reinforcing ribs (6), and an axial suspension hollow hole (8) is arranged between every two surrounding reinforcing ribs (6); two fixing lugs (4) are horizontally arranged at the bottom end of the periphery of the end cover.

The utility model has the advantages that: this device guarantees intensity unchangeably in the end cover quality, and its weight alleviates greatly to realize the air current circulation of the rear end of motor, further strengthened the rear end radiating effect of motor, the continuity of extension motor is long during operation.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a circumferential heat-dissipating motor end cover comprises a connecting hole 1, an inner connecting table 2, an airflow circulating hole 3, a fixing lug 4, a rotor suspension connecting hole 5, a surrounding type reinforcing rib 6, a fixing end 7 and a suspension type hollow hole 8.

This device adopts outer wrapping type to be connected with motor housing, is equipped with interior connection platform 2 in the one side that end cover and motor housing are connected, and motor housing directly contacts 2 with interior connection platform, and the 2 outsides of interior connection platform evenly set up three stiff ends 7, are equipped with connecting hole 1 on every stiff end 7. The hollow airflow circulation holes 3 are formed in the lower portion of the inner connecting table 2, and the airflow circulation holes 3 are evenly distributed at intervals of a certain distance around the end cover. The axial line of the end cover is provided with a rotor suspension connecting hole 5, the periphery of the rotor suspension connecting hole 5 is provided with surrounding reinforcing ribs 6, and an axial suspension type hollow hole 8 is arranged between every two surrounding reinforcing ribs 6. Two fixing lugs 4 are horizontally arranged at the bottom end of the periphery of the end cover.

The principle is as follows: the utility model discloses lie in motor overcoat contact segment, adopt the even fretwork of ellipse to when rotatory, produce the circumferential direction air current with electric motor rotor, spill in the oval hole from, thereby realize the air current circulation, further strengthen the radiating effect of motor during operation. The material is reduced to 1/2 of the prior material thickness at the joint of the rotor and the end cover, but the connection hole of the rotor and the end cover is processed by adopting a surrounding type reinforcing rib, so that the use strength of the rotor is ensured to be achieved when the rotor works. The connection part of the motor shell is in an outer wrapping type, so that the motor shell is convenient for daily maintenance. In quality, the strength requirement of the motor in use is ensured, and the weight of the motor is reduced.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
