Abstract
The utility model discloses a reversing piece of an insert piece type groove-shaped reverser. The reversing piece is characterized in that a wire chase is arranged on the excircle curved surface at the top of the reversing piece, and is arranged along the height direction of the reversing piece in the center of the excircle curved surface. The reversing piece not only can reduce material cost of the reverser, but also can solve the oblique problem of the reverser.
Description
Technical field
The utility model relates to a kind of commutator, what be specifically related to is a kind of commutator segment of blade inserting tank commutator.
Background technology
Traditional blade inserting tank commutator, the top cylindrical of its commutator segment all is smooth round surface, after the commutator assembling is finished, need go out wire casing in the top of every commutator segment cylindrical Machining of Curved Surface by the groove milling operation, causes waste on the cost; In addition, when commutator segment group was fitted together pressure injection phenolic moulding powder, owing to can not well be located between the commutator segment, the more special commutator of some end face moulding compound structures caused the generation of defective item with regard to occurring the oblique sheet problem of commutator segment easily.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of commutator cost that feeds intake that alleviates, and solves the commutator segment of the blade inserting tank commutator of the oblique sheet problem of commutator.
The utility model takes following technical scheme to finish:
The commutator segment of blade inserting tank commutator is characterized in that: round surface is provided with wire casing outside the top of described commutator segment, and wire casing round surface center outside is provided with along the commutator segment short transverse.
The beneficial effects of the utility model are: when making commutator segment directly outside the top at commutator segment round surface pull out wire casing, so just alleviated the commutator cost that feeds intake; When the commutator segment group of pulling out wire casing is fitted together pressure injection phenolic moulding powder, can simply set up the key element that wire casing is positioned on the mould, so just solved the oblique sheet problem of commutator easily.
Description of drawings
The utility model has the following drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing 1, this kind blade inserting tank commutator includes 21 commutator segments 1, and round surface is equipped with wire casing 2 outside the top of every commutator segment 1, and wire casing 2 is a rectangular shape, and wire casing 2 round surface center outside is provided with along the commutator segment short transverse.
Claims (1)
1. the commutator segment of blade inserting tank commutator, it is characterized in that: round surface is provided with wire casing outside the top of described commutator segment, and wire casing round surface center outside is provided with along the commutator segment short transverse.
