Abstract
The utility model relates to a rotor end holding plate which includes an end plate and holding plates arranged on the end plate. The holding plates are bulges arranged on the edge of the end plate. The rotor end holding plate solves the tooth expansion and tooth breakage problems existing in a conventional rotor core when the rotor core is overlapped. The rotor end holding plate can effectively prevent the tooth expansion phenomenon.
Description
Technical field
The utility model relates to a kind of rotor-end pressing plate, relates in particular to a kind of rotor-end pressing plate that is used for high-voltage motor.
Background technology
The rotor-end pressing plate is installed in the two ends of electric machine rotor iron core; Existing rotor-end pressing plate is that certain thickness steel plate processes, and the two sides of end clamp plate is the plane, when rotor core laminates; End clamp plate discontinuity, rotor core are easy to generate that tooth rises, the problem of broken teeth.
Summary of the invention
Occur easily when existing rotor core laminates in order to solve that tooth rises, the problem of broken teeth, the utility model provides a kind of rotor-end pressing plate that increases tooth intensity.
The technical solution of the utility model:
A kind of rotor-end pressing plate comprises end plate, and its special character is: also comprise the pressing plate that is arranged on the end plate, said pressing plate is the convexity that is arranged on the end plate edge.
Above-mentioned convexity is a detent projection.
The advantage that the utility model had:
In the rotor core lamination process; Because pressure, certain deformation can take place in the rotor-end pressing plate, and is similar with spring principle; The detent projection at the end clamp plate edge that the utility model is mentioned can tightly be pressed on the edge unshakable in one's determination, effectively prevents the generation that tooth rises.
Description of drawings
Fig. 1 is the structural representation of the utility model rotor-end pressing plate;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the installation diagram of the utility model rotor-end pressing plate and rotor core;
Wherein Reference numeral is: 1-end plate, 2-pressing plate, 3-rotor core.
Embodiment
As Fig. 1, shown in Figure 2 be the structural representation of the utility model, comprise end plate, also comprise the pressing plate that is arranged on end plate one side, pressing plate is the convexity that is arranged on the end plate edge.When electric machine rotor iron core laminates, be the generation that prevents that tooth from rising, a kind of like this end plate of ad hoc meter edge has the rotor-end pressing plate of detent projection.
The rotor-end pressing plate is arranged on the two ends of rotor core, and is in the process that laminates, unshakable in one's determination through two rotor-end pressing plate stacks; In the rotor core lamination process; Because pressure, certain deformation can take place in the rotor-end pressing plate, and is similar with spring principle; This moment, the detent projection at end clamp plate edge can tightly be pressed in (like Fig. 3) on the edge unshakable in one's determination, thereby the tooth that effectively prevents rises, the generation of broken teeth.
Claims (2)
1. a rotor-end pressing plate comprises end plate, it is characterized in that: also comprise the pressing plate that is arranged on the end plate, said pressing plate is the convexity that is arranged on the end plate edge.
2. rotor-end pressing plate according to claim 1 is characterized in that: said convexity is a detent projection.
