It is small outer circle 003, it is waste that this, which results in most of material from blank to finished product,.
Utility model content
To solve drawbacks described above, the utility model proposes the commutators for automobile starter, cancel the step of commutator,
Directly use uniform diameters.
What the technical solution of the utility model was realized in：For the commutator of automobile starter, including commutator sheet
Body, the commutator ontology include copper bar, mica sheet, axis hole, and the periphery of the commutator ontology surrounds inferior circle jointly
Cylindrical body, the copper bar is uniformly filled in the commutator ontology, and the mica sheet is set between adjacent copper bar；It is described
Mica sheet is provided at both ends with fixed feet, and square groove, the mica sheet and institute are equipped between the fixed feet and the mica sheet
It states and is fixedly connected by the reinforcing ring placed in the square groove between copper bar；The commutator ontology further includes the axis of commutator
The coaxial springs being equipped at hole.
Further, elliptical aperture is set between the both ends fixed feet of the mica sheet, and the elliptical aperture is described including two
Filling phenolic moulding powder in elliptical aperture.
Further, the axis hole is stepped, and the bore equipped with three stage ranks and the axis hole in the axis hole is by upper
First reduce from left to right and increase afterwards, the coaxial springs are set between three stage ranks.
Further, the copper bar is made of copper powder and phenolic moulding powder, and the weight percent of copper powder is more than 70%.
Further, the outer diameter of the coaxial springs is more than the internal diameter of the axis hole, and the internal diameter of the coaxial springs is less than
The internal diameter of the axis hole.
Further, it is be bonded by phenolic moulding powder between the coaxial springs and commutator ontology.
The beneficial effects of the utility model are：General step structure has been abandoned, ensure that commutator peripheral surface encloses jointly
Into the cylindrical body of upper inferior circle, reduce the waste of the material from blank to finished product manufacturing process.This is because needed for commutator
Material is determined that, using no step commutator, compared with having step commutator, wear-resistant surface is constant by maximum outer circle, maximum outer circle by
Step large cylindrical is reduced to small outer circle, therefore material requested significantly declines.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
