Abstract
The utility model relates to an avoid formula stator coil insulation skeleton, include: the upper end surface of the body is convexly provided with a gasket which is abutted against the stator sheet; the gasket is symmetrically provided with groove bodies avoiding the end parts of the rivets of the stator sheets; the groove body leaves a space for the end part of the rivet, the end part of the rivet can extend into the groove body, and the end face of the stator piece can be attached to the end face of the gasket.
Description
Technical Field
The utility model relates to an insulating skeleton specifically is an dodge formula stator coil insulating skeleton.
Background
The conventional stator coil group is formed by arranging a plurality of insulating frameworks in a circumferential manner, and because the stator sheets are provided with the rivet holes, the plurality of stator sheets are connected together by the rivets penetrating through the rivet holes, but the end parts of the rivets are propped against the gasket, so that the end surfaces of the stator sheets and the gasket have gaps and are not adhered enough;
in conclusion, how to attach the end faces of the stator sheets to the end faces of the spacers becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to realize the end surface fitting of the stator piece and the end surface of the gasket;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to an dodge formula stator coil insulation skeleton, include: the upper end surface of the body is convexly provided with a gasket which is abutted against the stator sheet; the gasket is symmetrically provided with groove bodies avoiding the end parts of the rivets of the stator sheets;
that is to say, the space is left for the rivet tip to the cell body, and the rivet tip can stretch into in the cell body, and the terminal surface of stator piece can laminate with the terminal surface of gasket like this.
Because the plurality of insulating frameworks are arranged in a circumferential manner, when the stator piece is spliced, two adjacent insulating frameworks are arranged in a vertically staggered manner, and chamfers are arranged on two sides of the gasket in order to enable the two adjacent insulating frameworks to be in a flush state; the chamfer angle is arranged from the bottom edge of the gasket to the top edge of the gasket in an inclined upward manner;
through setting up the chamfer, can let two adjacent gaskets can not be in dislocation state from top to bottom because of the interference of wire winding.
In addition, the avoiding stator coil insulating framework can be applied to the direct-current brushless motor.
The utility model has the advantages that: the utility model relates to an dodge formula stator coil insulation skeleton, the cell body leaves the space for the rivet tip, and it is internal that the rivet tip can stretch into the groove, and the terminal surface of stator piece can laminate with the terminal surface of gasket like this.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-body, 2-gasket, 3-groove, 4-chamfer, 5-bottom edge and 6-top edge.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to an avoid-type stator coil insulation skeleton, include: the stator comprises a body 1, wherein a gasket 2 abutting against a stator sheet is convexly arranged on the upper end surface of the body 1; the gasket 2 is symmetrically provided with groove bodies 3 avoiding the end parts of the rivets of the stator sheets;
that is to say, the space is left for the rivet tip to the cell body, and the rivet tip can stretch into in the cell body, and the terminal surface of stator piece can laminate with the terminal surface of gasket like this.
As shown in fig. 1, because a plurality of insulating frameworks are arranged in a circumferential manner, when the stator sheets are spliced, two adjacent insulating frameworks are arranged in a vertically staggered manner, and in order to enable the two adjacent insulating frameworks to be in a flush state, chamfers 4 are arranged on two sides of a gasket 2; the chamfer 4 is arranged from the bottom edge 5 of the gasket 2 to the top edge 6 of the gasket 2 in an inclined upward manner;
through setting up the chamfer, can let two adjacent gaskets can not be in dislocation state from top to bottom because of the interference of wire winding.
The utility model relates to an dodge formula stator coil insulation skeleton, the cell body leaves the space for the rivet tip, and it is internal that the rivet tip can stretch into the groove, and the terminal surface of stator piece can laminate with the terminal surface of gasket like this.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
