Abstract
The utility model discloses a novel end surface reverser. The novel end surface reverser comprises a reversing sheet and a plastic die body. The novel end surface reverser is characterized in that dovetail grooves are respectively arranged no a bottom end surface and an inside end surface of a part at which the reversing sheet is combined with the plastic die body; a reinforcing ring is inserted into the dovetail groove on the bottom end surface of the reversing sheet. The novel end surface reverse disclosed by the utility model has the advantages of being high in mechanical strength and high in high-speed performance.
Description
[technical field]
The utility model relates to a kind of commutator, particularly a kind of end commutator.
[background technology]
Commutator is widely used in the electromechanics trade, and commutator mainly contains end commutator, Hooked reverser and three kinds of patterns of tank commutator.The shortcoming that traditional end commutator exists has: the adhesion between commutator segment and the plastics die body is not strong, and mechanical strength is not high, and when commutator ran up with motor, commutator segment easily came off from the plastics die body, so the high speed performance of end commutator is relatively poor.
[summary of the invention]
For the deficiency that background technology exists, the purpose of this utility model is intended to provide the novel end commutator that a kind of mechanical strength is high, high speed performance is good.
The utility model is implemented by following technical solution:
Novel end commutator comprises commutator segment and plastics die body, it is characterized in that: bottom end face and inner side end that described commutator segment is combined with the plastics die body are equipped with dovetail groove.
End commutator of the present utility model, bottom end face and the inner side end of being combined with the plastics die body at commutator segment are equipped with dovetail groove, because the existence of dovetail groove, adhesion between commutator segment and the plastics die body is strengthened greatly, so improved the mechanical strength of commutator, made the high speed performance of commutator better.
Be equipped with reinforcing ring in the dovetail groove of described commutator segment bottom end face.Reinforcing ring the anti-radial pull ability that has improved commutator segment is set, improved the mechanical strength of commutator, make equally the high speed performance of commutator better.
[description of drawings]
Fig. 1 is structure chart of the present utility model.
[embodiment]
As shown in the figure, novel end commutator of the present utility model, comprise commutator segment 2, reinforcing ring 3 and plastics die body 1, described commutator segment 2 is provided with dovetail groove 4 with the bottom end face of plastics die body 1 combination, described commutator segment 2 is provided with dovetail groove 5 with the inner side end of plastics die body 1 combination, and described reinforcing ring 3 is located in the dovetail groove 4 of commutator segment bottom end face.
Novel end commutator of the present utility model, bottom end face and the inner side end of being combined with the plastics die body at commutator segment are equipped with dovetail groove, because the existence of dovetail groove, adhesion between commutator segment and the plastics die body is strengthened greatly, simultaneously because the existence of reinforcing ring, improve the anti-radial pull ability of commutator segment, thus, the utlity model has the advantage that mechanical strength is high, high speed performance is good.
Claims (2)
