The commutator segment of the commutator is applicable to groove type or hook type commutators with large specifications, the manufacturing cost of a commutator product can be greatly reduced and the mechanical strength and the overspeed performance of the commutator product are effectively improved.
Description
Technical field:
The present invention relates to a kind of commutator, be specifically related to a kind of commutator segment of commutator.
Background technology:
Commutator product mainly contains three kinds of Hooked reverser, tank commutator and end commutators.Wherein, the major part of tank commutator is the grooved commutator segment with bonding wire groove, and grooved commutator segment is along independently many of the circle distribution of commutator, and every grooved commutator segment is combined with commutator matrix by its fixing feet; The major part of Hooked reverser is the hook commutator segment with crotch portion, and hook commutator segment is along independently many of the circle distribution of commutator, and every hook commutator segment is combined with commutator matrix by its fixing feet.The grooved commutator segment overwhelming majority of tradition tank commutator is made by the copper section bar that stretches, also there is only a few to adopt copper pipe (as the patent No. 201220095515.0, the disclosed technical scheme of patent name " commutator segment group of end commutator ") cutting after make, the commutator segment of the tank commutator making with said method is solid construction, for large specification tank commutator, the overall dimension of grooved commutator segment is also large, obviously cost also can improve greatly, the Heavy Weight of grooved commutator segment simultaneously, when work, can produce very large centrifugal force, and being limited to prior art, the adhesion of grooved commutator segment in the time of tank commutator injection mo(u)lding and between commutator matrix can not have significant improvement, so just have a strong impact on mechanical strength and the hypervelocity performance of tank commutator product, the mechanical strength of tank commutator product and hypervelocity performance can not be further enhanced, the application of large specification tank commutator is limited significantly.Made by stretching copper section bar and the hook commutator segment of traditional Hooked reverser is also most, also there is only a few to adopt global copper volume (to roll into cylindricality copper shell shape by copper coin, as the patent No. 201220283301.6, patent name " commutator " or the patent No. 201220083734.7, the disclosed technical scheme of patent name " the copper volume of making for commutator ") make after cutting, the hook commutator segment of the Hooked reverser making with said method is also solid construction, for large specification Hooked reverser, the overall dimension of hook commutator segment is also large, obviously cost also can improve greatly, the Heavy Weight of hook commutator segment simultaneously, when work, can produce very large centrifugal force, and being limited to prior art, the adhesion of hook commutator segment in the time of Hooked reverser injection mo(u)lding and between commutator matrix can not have significant improvement, so just have a strong impact on mechanical strength and the hypervelocity performance of Hooked reverser product, the mechanical strength of Hooked reverser product and hypervelocity performance can not be further enhanced, the application of large specification Hooked reverser is limited significantly.
Summary of the invention:
In view of the deficiency of background technology, object of the present invention aims to provide one and is applicable to large specification grooved or Hooked reverser, can greatly reduce the manufacturing cost of commutator product, and effectively improves the commutator segment of mechanical strength and the hypervelocity performance of commutator product.
The present invention takes following technical scheme to complete:
A commutator segment for commutator, is one of many independent lamellar bodies distributing on commutator circumference, it is characterized in that: every commutator segment self there is hollow-core construction, the thin-walled copper coin stamping that every commutator segment is no more than 1mm by thickness forms after bending.
Adopt the commutator segment of the commutator of technique scheme, maximum innovative point be make every commutator segment self realized hollow-core construction, it is different from the solid commutator segment being made by stretching copper section bar, also be different from the commutator segment making after being cut by copper pipe or global copper cut roll, useful technique effect of the present invention is: 1. under the constant prerequisite of the overall dimension of commutator segment, obviously the materials of copper material obtain a large amount of savings, thereby cost is reduced greatly, all the more so for large specification grooved or Hooked reverser; 2. the weight of commutator segment can reduce greatly, the centrifugal force producing when work also can reduce greatly, and commutator segment is in the time of commutator injection mo(u)lding, the plastic material of commutator matrix can be injected into the hollow interior of commutator segment, adhesion between commutator segment and commutator matrix can obtain enhancing to a certain extent, the reduction of centrifugal force and the enhancing of adhesion all can make the mechanical strength of commutator product and hypervelocity performance be improved significantly, thereby effectively expand the range of application of large specification grooved or Hooked reverser.
For tank commutator, the preferred structure of its hollow grooved commutator segment is: commutator segment is by sheet body, bonding wire slot part and fixed foot portion composition, thin-walled copper coin stamping is symmetrical slab construction before bending, the left and right sides of thin-walled copper coin stamping is provided with the dovetail that forms commutator segment fixed foot portion, the sheet body of commutator segment is formed by the left and right sides of thin-walled copper coin stamping simultaneously after the back side direction of thin-walled copper coin stamping exceedes the bending of 90 °, the center upper portion region of thin-walled copper coin stamping is provided with inverted T shape open slot, the copper coin in this region is with inside 90 ° of bonding wire slot parts that are bent to form thread-changing sheet again after commutator segment sheet body bending.
For Hooked reverser, the preferred structure of its hollow hook commutator segment is: commutator segment is by sheet body, crotch portion and fixed foot portion composition, thin-walled copper coin stamping is symmetrical slab construction before bending, the left and right sides of thin-walled copper coin stamping is provided with the dovetail that forms commutator segment fixed foot portion, the sheet body of commutator segment is formed by the left and right sides of thin-walled copper coin stamping simultaneously after the back side direction of thin-walled copper coin stamping exceedes the bending of 90 °, the top of thin-walled copper coin stamping is provided with left and right hook sheet, left and right hook sheet exceedes the crotch portion that forms thread-changing sheet after the bending of 90 ° to the frontal of thin-walled copper coin stamping.
