Abstract
The utility model relates to an iron core of a motor stator, which particularly relates to an iron core of a motor stator which is formed by splits. The iron core of a motor stator comprises an iron core main body, and the iron core main body is formed by a plurality of splits which are divided on the circumferential direction, each split is formed by a plurality of steel straps which are laminated, both ends of the steel straps on the circumferential direction are both provided with tenon slots, conduits of the tenon slots are formed on the splits, and adjacent splits are connected through a connecting piece which is adapt to the conduits of the tenon slots. The iron core of the motor stator which is provided by the utility model has reasonable structure, each split is connected with the connecting piece through the tenon slots, processing efficiency is greatly improved, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of iron core of motor stator, relates in particular to a kind of iron core of the motor stator that is combined by distinguish.
Background technology
The iron core of existing motor stator, its iron core body is combined by a plurality of distinguish of upwards dividing in week, and described each distinguish constitutes by some steel discs are stacked, is mostly between these distinguish to be connected by the means of welding.This connected mode makes that the production and processing of product is comparatively consuming time, the consumption manpower, and production cost is higher.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of iron core of motor stator, and it is rational in infrastructure, is connected with connector by tongue-and-groove between each distinguish, has improved working (machining) efficiency greatly, has reduced production cost.
The utility model solves the problems of the technologies described above by following technical proposals: a kind of iron core of motor stator, comprise the iron core body, described iron core body is combined by a plurality of distinguish of upwards dividing in week, described each distinguish constitutes by some steel discs are stacked, the two ends that make progress in described steel disc week are equipped with tongue-and-groove, be formed with the tongue-and-groove conduit on the described distinguish, two adjacent distinguish are by being connected with the suitable connector of tongue-and-groove conduit.
As preferably, described tongue-and-groove is a dovetail groove, and the dovetail portion of two symmetries is arranged on the described connector.
As preferably, described tongue-and-groove is an oval groove, and the ellipse tenon portion of two symmetries is arranged on the described connector.
Certainly, described tongue-and-groove also can be the tongue-and-groove of other forms such as square, polygon.
As preferably, the two ends of described connector all are formed with two blocks of bending laterally.
As preferably, described iron core body is combined by 2 equal distinguish upwards dividing in week.
As preferably, described iron core body is combined by 4 equal distinguish upwards dividing in week.
As preferably, described iron core body is combined by 6 equal distinguish upwards dividing in week.
As preferably, described iron core body is combined by 9 equal distinguish upwards dividing in week.
Adopt the utility model of the technical program, its beneficial effect is:
1. the two ends that make progress in steel disc week of the utility model are provided with tongue-and-groove, so are formed with the tongue-and-groove conduit on the distinguish that is laminated of steel disc, and upwards the tongue-and-groove conduit at two ends and the tenon portion of connector link to each other two adjacent distinguish by its week.Adopt above-mentioned connected mode to replace existing welding manner, improved operating efficiency.
2. at the two ends of described connector block is set, can prevents effectively that connector from skidding off in the tongue-and-groove conduit, make core structure more stable.In actual production, the iron core that only needs to insert connector is placed on the stamping machine, and this moment, outstanding iron core surface was omited at the two ends of connector, by the mode of punching press the block punch forming at connector two ends was fixed.
