Abstract
The invention discloses an automobile starting motor housing. The automobile starting motor housing comprises a cylindrical housing formed by curling a hot-rolled steel plate; a stress-relieving groove is formed in the inner wall of the housing; two connecting edges of the housing are locked; a connecting lug is arranged at one connecting edge of the housing, while a connecting sunk part corresponding to the connecting lug is arranged at the other connecting edge of the housing; the connecting sunk part and the connecting lug are consistent in size; the connecting sunk part is clamped in the connecting lug to realize the locking of the two connecting edges of the housing; the connecting lug is of a handle-shaped structure which is wide in exterior and narrow in interior; the connecting sunk part is of the handle-shaped structure which is wide in interior and narrow in exterior. According to the automobile starting motor housing, direct locking is adopted and the stress-relieving groove is designed, and therefore, the production cost can be greatly saved while the production quality and the service life of the starting motor housing are increased.
Description
Technical field
The invention belongs to starter motor technical field, be specifically related to a kind of starting motor of automobile shell.
Background technology
Vapour starting motor of automobile excitation shell is the vitals of starting motor of automobile, and be the framework producing magnetic element, its quality will directly have influence on the startup ability of starter motor, the waveform of induced electromotive force and vehicle performance.
All can there is stress after the processing of existing vapour starting motor of automobile excitation shell and the situation such as concentrate, the circularity that the existence due to stress causes shell is poor, greatly have impact on the properties of motor.
Structure and the processing mode of current starting motor of automobile excitation shell mainly contain following several:
1, adopt that seamless steel pipe is machined makes, the subject matter of existence is:
(1) the technique process equipment that relates in the conventional machine side of adding is various, and technique is loaded down with trivial details, causes that working (machining) efficiency is low, manufacturing cost is high, expensive;
(2) phosphorus content of existing seamless steel pipe high (phosphorus content is up to 20%), phosphorus content height can cause motor magnetic loss serious, and starting efficiency reduces gradually, until lost efficacy;
(3) conventional machining process precision is low, consistency is poor, and percent defective is high.
2, adopt the Product jointing rolling into tubular to form, the subject matter of existence is:
(1) welding needs to polish after there is rough solder joint, thus adds production process, so add cost;
(2) welding easily produces stress, thus affects the circularity etc. of product, so affect the various performances of starter motor.
Also do not have a kind of reasonable in design, dependable performance at present, production cost is low, and material consumption is few, is convenient to the switch casing of automobile start motor manufacturing and process.
Summary of the invention
For solving above technical problem, the invention provides that a kind of quality is good, the starting motor of automobile excitation housing of long service life.
Its technical scheme is as follows:
A kind of starting motor of automobile shell, is characterized in that: comprise the cylinder shell (1) rolled by hot rolled steel plate, the inwall of described housing (1) is provided with destressing groove (c);
Two fillet snappings of described housing (1), be provided with at a fillet of described housing (1) and connect protuberance (a), another fillet is provided with connection depressed part (b) corresponding with described connection protuberance (a), described connection depressed part (b) be connected the in the same size of protuberance (a), this connection depressed part (b) is installed in described connection protuberance (a), thus realize the snapping of described housing (1) two fillet, described connection protuberance (a) is in the lever type structure for outside wide internal pinch, the lever type structure that the inner wide outside of described connection depressed part (b) is narrow.
The deficiency that adopt above structure to significantly solve in existing production to adopt car to add and welding etc. exists, adopt direct snapping, that the lever type structure of circular arc connects due to what adopt, the operations such as chamfering are not needed effectively to connect, so improve the quality of production of the present invention and while useful life, greatly saving production cost.Simultaneously due to the existence of destressing groove, greatly eliminate the stress of the present invention in coiling process and concentrate, circularity of the present invention is improved greatly.
As preferably: described destressing groove (c) hoop is distributed on the inwall of described housing (1), and the elimination of counter stress like this is more obvious.
As preferably: described destressing groove (c) is three, between two openings being evenly distributed on described housing (1), so distribution is comparatively reasonable, can eliminate the stress of various piece of the present invention.
As preferably: described connection protuberance (a) is several, and be distributed in described housing (1) fillet on, can realize reliably like this connecting, more firmly.
As preferably: the two kinds of protuberances differed sized by described connection protuberance (a), large described connection protuberance (a) and little described connection protuberance (a) interlaced arrangement are on the fillet of described housing (1), adopt above structure, be cross-linked and the present invention is not easily misplaced, ensure that the center of circle of the present invention degree.
Beneficial effect: the starter motor excitation housing adopting above technical scheme, structure is simply novel, easily manufactured, connects reliable, can eliminate stress in production process largely and concentrate, improve circularity, the life-span of product is extended.
