Abstract
The utility model discloses a kind of shell of motor, including body and two end caps, the body is clamped between two end caps, linked together between two end caps by screw rod so as to form chucking power to the body, the screw rod is arranged on the outside of the body, and the quantity of the screw rod is more and is evenly distributed on outside the body.Linked together between two end caps by screw rod so as to form chucking power to the body, screw hole need not be set on body, reduce the requirement of body thickness, body can be made relatively thin, so as to save manufacture cost.Body can be thin to 1 2mm by steel plate roll-forming, thickness, dramatically saves on material, reduces the material cost of product, and can set heat emission hole.
Description
Technical field
It the utility model is related to a kind of shell of motor.
Background technology
It refer to Fig. 1, two end caps 2 of the shell of motor by body 1 and at left and right sides of body form, and body is used for
Stator core and rotor are placed, end cap 2 is then used for the opening for covering body 1, and plays a supportive role to the output shaft of motor.Assembling
When, stator core is made after finished product by techniques such as embedding, dipping lacquers, and with external force press-in body 1, two end caps 2 are then from left and right
Both sides position stator core, are locked between end cap 2 and body 1 by bolt 3.
Due to needing the hole 4 of reserved lock bolt 3 on body 1, the thickness of body 1 needs to be made larger, can not use
The structure that steel plate rolls, is typically that Aluminum alloy tensile or pig iron casting form, and causes manufacture cost higher.
Utility model content
The utility model provides a kind of shell of motor, which overcomes the deficiency present in background technology.This practicality is new
Technical solution is used by type solves its technical problem：
A kind of shell of motor, including body and two end caps, the body are clamped between two end caps, are passed through between two end caps
Screw rod links together so as to form chucking power to the body, which is arranged on the outside of the body, and the quantity of the screw rod is
More and it is evenly distributed on outside the body.
Among one preferred embodiment：The body is by steel plate roll-forming.
Among one preferred embodiment：The thickness of the body is 1-2mm.
Among one preferred embodiment：The body is equipped with heat emission hole.
Among one preferred embodiment：The end cap is equipped with heat emission hole.
Among one preferred embodiment：The quantity of the screw rod is three.
Among one preferred embodiment：The end cap is equipped with the boss of circle shape towards the end face of the body, the boss
Outside diameter is slightly less than the aperture of the body, which is embedded into the body；The outer circumferential surface of the boss is equipped with locating piece, the body
End be equipped with location hole, which is inserted into the location hole.
Among one preferred embodiment：The width of the location hole is bigger 0.1-0.2mm than the width of the locating piece.
Compared with background technology, it has the following advantages that the technical program：
1. being linked together between two end caps by screw rod so as to form chucking power to the body, need not be set on body
Screw hole, reduces the requirement of body thickness, and body can be made relatively thin, so as to save manufacture cost.
2. body thin can be arrived 1-2mm, dramatically saves on material, reduce product by steel plate roll-forming, thickness
Material cost, and heat emission hole can be set.
3. during assembling, the locating piece on the end cap boss is inserted into the location hole of the body, and end cap is just stuck, it is impossible to
Rotated on body, fast positioning, simple, efficient, registration, when saving assembling can be carried out to the stator core of motor
Between, reduce cost of labor.

Embodiment
Fig. 1, a kind of shell of motor of the utility model, including body 10, two end caps 20 and more screw rods 30 are refer to,
The body 10 is clamped between two end caps 20, is linked together between two end caps 20 by screw rod 30 so as to be formed to the body 10
Chucking power, that is to say, that the screw rod 30, which tenses two end caps 20, makes two end caps 20 clamp the body 10.The screw rod 30 is arranged on the shell
The outside of body 10, the quantity of the screw rod 30 are more and are evenly distributed on outside the body 10.
The body 10 is by steel plate roll-forming.The thickness of the body 10 is 1-2mm.The body 10 is equipped with multiple heat emission holes
12.Multiple heat emission holes 22 also are provided with the end cap 20.
The quantity of the screw rod 30 is three.
The end cap 20 is equipped with the boss 24 of circle shape towards the end face of the body 10, and the outside diameter of the boss 24 is slightly less than
The aperture of the body 10, the boss 24 are embedded into the body 10.The boss 24 is actually the structure of tongue and groove.The boss 24
Outer circumferential surface be equipped with locating piece 26.The end of the body 10 is equipped with location hole 14, which is inserted into the location hole 14
It is interior.During assembling, which is buckled in the end of the body 10 vertically, among the boss 24 insertion body 10, the locating piece 26
It is inserted at the same time in the location hole 14.Preferably, the width of the location hole 14 is bigger 0.1-0.2mm than the width of the locating piece 26,
Effectively prevent the end cap 20 from rotating.
The above, is only the utility model preferred embodiment, therefore cannot limit the utility model implementation according to this
Scope, i.e., the equivalent changes and modifications made according to the utility model patent scope and description, it is new all should still to belong to this practicality
In the range of type covers.
