The insulating bracket of the tachometer generator stator comprises a substrate (1) of a circular ring shape. The outer diameter of the substrate is slightly smaller than the outer diameter of the stator core. The inner diameter of the substrate is equal to slightly larger than the inner diameter of the stator core. The stator is symmetrically provided with thin-walled bushings (5) with both ends opened along the circumferential direction of the substrate. The bushings are perpendicular to one side face of the substrate and extend outward. The bushings have a shape matched with wire slots on the stator core. The bushings have positions on the substrate corresponding to the wire slots on the stator core. The extending length of the bushings is equal to or slightly smaller than half of the thickness of the stator core. Gaps (6) are provided on walls of the bushings. The gaps are intersected with an inner circle of the substrate. The number of the bushings is 18. The insulating bracket can make the bushings all be underlaid in the wire slots in one operation, and greatly improves the efficiency; and the insulating bracket improves the insulation strength of stator windings and the stator core.

The insulating support of tachogenerator stator

Technical field

The utility model relates to a kind of insulating material goods, especially a kind of insulating support of tachogenerator stator.

Background technology

For the stator winding that guarantees tachogenerator and the dielectric strength between the stator slot, common pad insulation film between wire casing and winding, therefore this be necessary to improve so that the rule operation is very inconvenient.

The utility model content

The technical problems to be solved in the utility model is, a kind of insulating support of tachogenerator stator is provided, this insulating support can be assemblied on the stator core of tachogenerator, on the basis that guarantees dielectric strength between stator winding and the stator core, makes things convenient for the rule operation.

The insulating support of this tachogenerator stator is made by insulating material, it comprises the substrate 1 of toroidal, be used with the stator core of tachogenerator, the external diameter of substrate 1 is slightly less than the external diameter of stator core, the internal diameter of substrate 1 equals or is slightly larger than the internal diameter of stator core, stator is symmetrically arranged with the lining 5 of the thin-walled of both ends open along the circumferencial direction of substrate, lining 5 stretches out perpendicularly with a side of substrate, lining 5 has the shape that matches with wire casing on the stator core, lining 5 has the position corresponding with the wire casing on the stator core at substrate 1, the length that lining 5 stretches out is equal to or slightly less than 1/2 thickness of stator core, the wall of described lining is provided with gap 6, gap 6 intersects with the inner circle of substrate 1, and the quantity of described lining 5 is 18.

Limit section in substrate 1 another side is provided with flange 2, is provided with the narrow tooth 3 of several strips in the inboard of flange 2, between narrow tooth 3 and the flange 2 gap is arranged, narrow tooth 3 is along extending with lining 5 opposing directions, the length that narrow tooth 3 extends is 6mm, and described narrow tooth 3 quantity equate with the quantity of described lining 5.

On the inner circle of substrate 1 another side, also be symmetrically arranged with tabular wide tooth 4, wide tooth 4 is between two adjacent linings 5, wide tooth 4 is along extending with lining 5 opposing directions, and the length that wide tooth 4 extends is 4-6mm, and the quantity of described wide tooth 4 equates with the quantity of described lining 5.

Need in wire casing one by one pad insulation film for the stator winding that guarantees tachogenerator and the dielectric strength between the stator slot in the prior art, and the flat shape of insulating support of the present utility model is similar to the flat shape of tachogenerator stator iron core substantially, can insert its wire casing from the two ends of stator core easily, as long as once-through operation can make lining 5 whole pads in wire casing, greatly improved efficient; After this insulating support inserts stator core, so that the surface of stator slot and cover with lining and substrate that the end face of its stator core that intersects is insulated respectively support, so not only make between stator winding and the stator slot and insulate, and can make between stator winding and the stator core end face and insulate, improved the dielectric strength between stator winding and stator core integral body.
