Abstract
The utility model discloses a planar commutator. The planar commutator has the cone appearance; the end surface of the large end of the cone is a working surface; the working surface is formed by laying the end surfaces of the tops of commutator segments which are uniformly distributed along the periphery; and bonding wire slots are arranged on the outer side surfaces of the commutator segments. The planar commutator is characterized in that grooves are arranged on the end surfaces of the bottoms of the commutator segments, included angles between the groove edges at the outer sides of the grooves and the bottoms of the grooves are acute angles, included angles between the groove edges at the inner sides of the grooves and the bottoms of the grooves are right angles, and dovetail grooves are arranged on the inner side surfaces of the commutator segments. The planar commutator has good high speed performance and long service life.
Description
[technical field]
The utility model relates to a kind of flat commutator.
[background technology]
Traditional flat commutator mainly has following two deficiencies selected: the one, and the design of commutator segment is reasonable inadequately; The die body adhesion of commutator segment and commutator is not strong; Under fast state, commutator segment comes off from the die body of commutator easily, and commutator is not long useful life; The 2nd, flat commutator does not adopt the reinforcing ring reinforcement technique of other type commutator owing to design reasons, and the anti-radial pull ability of commutator segment is relatively poor, also causes commutator segment to come off from the die body of commutator easily.
[summary of the invention]
In view of the deficiency of prior art, the technical problem that the utility model will solve is to be to provide a kind of high speed performance good, the flat commutator of long service life.
The utility model takes following technical scheme to accomplish: a kind of flat commutator, have the cone profile, and the big end end face of cone is a working face; Working face is laid by the top end of the commutator segment of circumference uniform distribution and is formed; The lateral surface of commutator segment is offered the bonding wire groove, it is characterized in that: the bottom end face of commutator segment is provided with groove, and the outside trough rim of groove and the angle of bottom land are acute angle; The inside slot edge of groove and the angle of bottom land are the right angle, and the medial surface of commutator segment is provided with dovetail groove.Be provided with reinforcing ring in this flat commutator, reinforcing ring fastens the inside slot edge setting of said groove.
The utility model has two bright spots: the one, and the bottom end face of commutator segment and medial surface have adopted the composite type trench structure; Strengthen the adhesion between commutator segment and the commutator die body, so just effectively improved the high speed performance of commutator, under fast state; Commutator segment is not easy to come off from the commutator die body; The commutator long service life, the 2nd, adopted the reinforcing ring reinforcement technique, improve the anti-radial pull ability of commutator segment.
[description of drawings]

Fig. 2 is the A-A view of Fig. 1.
[embodiment]
As shown in the figure, this flat commutator has the cone profile; The big end end face of cone is a working face, and working face is laid by the top end of 23 commutator segments 1 of circumference uniform distribution and formed, and the lateral surface of commutator segment 1 is offered bonding wire groove 2; The bottom end face of commutator segment 1 is provided with groove 3; The outside trough rim of groove and the angle of bottom land are acute angle, and the inside slot edge of groove and the angle of bottom land are the right angle, and the medial surface of commutator segment 1 is provided with dovetail groove 4; Be provided with reinforcing ring 5 in the said commutator, reinforcing ring 5 fastens the inside slot edge setting of said groove 3.
The flat commutator of the utility model, commutator segment have adopted the composite type trench structure, have strengthened the adhesion between commutator segment and the commutator die body; And adopted the reinforcing ring reinforcement technique, improved the anti-radial pull ability of commutator segment, so; The utility model high speed performance is good, long service life.
Claims (2)
