Abstract
The invention relates to a direct-current motor shell which is internally provided with a motor stator punching and comprises an integral shell which is constituted by a first basic shell, an intermediate shell and a second basic shell, wherein, the first basic shell, the intermediate shell and the second basic shell are connected through pulling rods in turn in a tensioning manner; the pulling rods are distributed on the whole body of the shell; the length of the intermediate shell is arranged correspondingly according to the number of the stator punching, namely the length of a stator core formed by the stator punching. By changing the structure of the shell, the invention changes the shell into a two-piece type from an integral type; when the length of the stator core changes, the shelllength of the intermediate shell only needs to be changed, thereby simplifying the length of the whole shell size; a large number of moulds need not to be manufactured, thus saving a great deal of cost spent on moulds and saving the cost spent on motors.
Description
Technical field
The present invention relates to direct current machine, relate in particular to a kind of improved direct-current motor shell.
Background technology
As everyone knows, existing casing structure is all-in-one-piece, utilizes mould to cast.When the electrical characteristic of motor need be adjusted,,, be commonly called as and adjust stator core length so the general method that increases or reduce the stator piece number that adopts is reached because the mould punching of stator piece is very difficult.Length dimension that so certainly will casing also needs to do corresponding adjustment.Yet as shown in Figure 1 and Figure 2, all-in-one-piece casing structurally presents scrambling because the existence of terminal box 1 ' and radiating ribs 2 ' is arranged, and the manufacturing of all casings generally adopts casting, therefore needs the identical mould of manufacturing specification, and casting forms then.When the length of casing changes, must make the mould of casing again, such mould cost is also very huge.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the present invention aims to provide a kind of split type direct-current motor shell, thereby can become easy so that adjust the casing length dimension, and has saved a large amount of die cost.
A kind of direct-current motor shell of the present invention, in be provided with motor stator punching, it is characterized in that: it comprises the whole housing that is made of first base house, middle casing and second base house, and described first base house, middle casing and second base house are strained successively by pull bar and are connected, and described pull bar is distributed in the housing whole body.
In above-mentioned direct-current motor shell, the length of described middle casing is by the quantity of described stator punching, i.e. the length relative set of the stator core that stator punching constituted.
In above-mentioned direct-current motor shell, the surface of described whole housing is scattered with radiating ribs.
In above-mentioned direct-current motor shell, the described first base house mounted on surface has a terminal box.
In above-mentioned direct-current motor shell, described whole housing is cylindric.
Owing to adopted above-mentioned technical solution, the present invention is by changing the structure of casing, become casing split type by integral type, when stator core length changes, only need to change the length casing of middle casing, thereby make adjustment casing length dimension become easy, do not need out a large amount of moulds of system, thereby saved a large amount of die costs, saved motor cost.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
See also Fig. 3, and in conjunction with Fig. 4, Fig. 5, the present invention, be a kind of direct-current motor shell, in be provided with the motor stator punching (not shown), it comprises the whole housing 10 that is made of first base house 1, middle casing 2 and second base house 3, and first base house 1, middle casing 2 and second base house 3 are strained successively by pull bar 4 and are connected, and pass through nut 5 at pull bar 4 two ends and lock, making it to form an integral body, pull bar 4 is distributed in the housing whole body.
The length of middle casing 2 is pressed the quantity of stator punching, and promptly the length of the stator core that stator punching constituted is provided with.
The whole housing 10 that first base house 1, middle casing 2 and second base house 3 are constituted is cylindric, and the surface of whole housing 10 is scattered with radiating ribs 7.
First base house, 1 mounted on surface has a terminal box 6.
Motor case after the improvement provided by the invention is divided into syllogic, two ends are respectively first base house 1 and second base house 3, the mould of concentricity high motor base house only need be opened system once, after first base house 1, middle casing 2 and 3 cast moldings of second base house, 4 pull bars by the whole body are strained and fixed again, can form a whole housing 10.When the length of casing need be adjusted, only need open the mould of system intermediate casing again, the spending of having saved mould has so greatly reduced cost.
In sum, the present invention is divided into three sections by improving the structure of motor case with original all-in-one-piece casing, need not go changes after the section of foundation mould is made again, if the stator core because the motor electrical characteristic need extend need get final product by the variation interlude.And interlude has only the variation of axial dimension, appearance structure unanimity in the manufacturing process of mould.The manufacturing of mould will be more easy like this, and the manufacturing cost of mould also will reduce greatly.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
