Abstract
The utility model relates to a coordination structure of an electrical power steering (EPS) motor commutator, a shaft sleeve and a shaft, which comprises the commutator, the shaft sleeve and the shaft. The commutator and the shaft sleeve are sleeved on the shaft. The coordination structure is characterized in that a groove is arranged at the tail of the commutator, a clamping hook is arranged at one end of the shaft sleeve, and the commutator and the shaft sleeve are positioned through the coordination of the clamping hook and the groove. The coordination structure of EPS motor commutator, the shaft sleeve and the shaft saves cost, is reliable in coordination, stable in quality and convenient to manufacture, and improves working efficiency.
Description
Technical field
The utility model relates to the fit structure of a kind of EPS engine commutator and axle sleeve and axle, belongs to the improvement technology of EPS engine commutator and axle sleeve and between centers fit structure.
Background technology
Cooperating between existing EPS engine commutator and the axle sleeve do not have coupler construction, all needs gluing like the coiling line ball, and the axiality of EPS engine commutator and axle sleeve guarantees difficult; Gluing is unreliable connection also, has the glue risk that comes off, and is difficult to guarantee because of axiality simultaneously; Might press quick-fried commutator during assembling; Installation produces adverse consequences, and recessively presses quick-fried also being difficult to find, once possibly cause the stuck equivalent risk of motor.And existing axle sleeve cooperates no step to keep away bit architecture with between centers,, commutator exists when going into spool because of component tolerances, and axle sleeve and overlay or have the gap, otherwise existence is than thrust even pressure break greatly, and there is potential safety hazard in electrical machine insulation.
Along with domestic EPS electromechanics trade develops, in order to obtain more reliably more convenient installation, must design safer positive connection, but can not raise the cost again simultaneously, therefore, it is important that commutator and axle sleeve structure design cause the pass.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art and a kind of axiality that can guarantee commutator and axle sleeve is provided; Cooperate more reliable, steady quality, easy to make; Practice thrift cost, the fit structure of EPS engine commutator of enhancing productivity and axle sleeve and axle.
In order to achieve the above object, the utility model is achieved in that it is the fit structure of a kind of EPS engine commutator and axle sleeve and axle, comprises commutator, axle sleeve and axle, and said commutator and axle sleeve are set on the axle; It is characterized in that being provided with groove, be provided with trip at an end of said axle sleeve at the afterbody of said commutator, said trip with make commutator and axle sleeve location cooperating of groove.
The other end of said axle sleeve is provided with step groove, is provided with the coating insulating barrier on the surface of said axle.
The utility model advantage compared with prior art is: can guarantee the axiality of commutator and axle sleeve, cooperate more reliable, steady quality, easy to make, practice thrift cost, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further detailed description below:
Shown in 1 figure, it is the fit structure of a kind of EPS engine commutator and axle sleeve and axle, comprises and changing
To device 6, axle sleeve 7 and axle 5, said commutator 6 and axle sleeve 7 are set on the axle 5; The utility model characteristics are that the afterbody at said commutator 6 is provided with groove 1, are provided with trip 2 at an end of said axle sleeve 7, said trip 2 with make commutator 6 and axle sleeve 7 location cooperating of groove 1.This structure effectively solves the articulation issues between commutator and the axle sleeve, and the automatic aligning function is arranged, and does not need gluing, reduces cost, and qualification rate obviously improves.
In the present embodiment, the other end of said axle sleeve 7 is provided with step groove 3, is provided with on the surface of said axle 5 and applies insulating barrier 4.This structure effectively solves and applies the pressure break problem, thoroughly solves Insulation Problems, and cost has a little reduction because of few with material simultaneously.
Claims (2)
