Abstract
The utility model discloses a commutator segment of a commutator of a motor. An embedding part of the commutator segment of the commutator of the motor is provided with a forked tail. It is characterized in that the forked tail is a double overlaying forked tail. The absorption firmness of the commutator segment of the commutator of the motor and a commutator body is strengthened. In this way, the outer diameter and the deformation volume among the commutator segments of the commutator in a high speed running state are reduced, thereby improving the service lifetime of the commutator.
Description
Technical field
The utility model relates to a kind of improvement invention of commutator segment of engine commutator.
Background technology
Motor extensively and is in large quantities used in every profession and trade production field and family, public place etc., and is closely related with life with people's work.Along with the progress of society, industrial greatly develops, and particularly automobile industry is swift and violent, and the utilance of motor in car load is very high, and automobile is high again to the degree of safety requirement of performance, makes that the commutator part in the motor also will have high-quality to guarantee useful life and safety.Present commutator for electric motor; The implantation portion of its commutator segment has and adopts the dovetail structure, but is single dovetail, the absorption firmness between the commutator segment of single dovetail and the commutator die body a little less than; Deflection is bigger between the external diameter of commutator product under the high speed operation state and sheet, has shortened useful life.
Summary of the invention
Problem in view of known technology existence at present; The technical problem that the utility model will solve is the commutator segment that is to provide a kind of engine commutator; Absorption firmness between this commutator segment and the commutator die body strengthens; Deflection reduces between the external diameter of commutator product under the high speed operation state and sheet, has improved useful life.
The utility model takes following technical scheme to accomplish:
A kind of commutator segment of engine commutator, its implantation portion has dovetail, it is characterized in that: this dovetail is two superposing type dovetails.
The beneficial effect of the utility model is: the implantation portion of commutator segment has adopted two superposing type dovetails; Absorption firmness between commutator segment and the commutator die body strengthens greatly like this; Deflection will reduce between the external diameter of commutator product under the high speed operation state and sheet, has improved useful life.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to accompanying drawing 1, a kind of commutator segment 1 of engine commutator, its implantation portion has dovetail 2; This dovetail 2 is two superposing type dovetails; Two superposing type dovetails have two place's intensity absorption affinity faces 3, compare place's intensity absorption affinity face of the single dovetail of prior art, and the absorption firmness between the utility model and the commutator die body strengthens greatly; Deflection will reduce between the external diameter of commutator product under the high speed operation state and sheet, has improved useful life.
Draw following data through overspeed test: existing single dovetail design, at 180 ℃, the 30000rpm 3min that turn round, the external diameter of commutator is changed to 0.014max, and the section difference is 0.005max between sheet; Two superposing type dovetails of the utility model, at 180 ℃, the 36000rpm 3min that turns round, the external diameter of commutator is changed to 0.012max, and the section difference is 0.004max between sheet.Can find out obviously that from above data the utility model is under the prerequisite that improves rotating speed 6000rpm, the maximum of section difference also reduces to some extent between external diameter variation and sheet.
