Abstract
The utility model discloses a ball bearing permanent magnetism step motor with adjustable it is automatic, motor include rotor, stator, center pin, pivot, front end housing, rear end cap, apron, plastics support, output gear, ball bearing, front end housing and rear end cap respectively with stator fixed connection, the rotor is located between front end housing and the rear end cap, inside the one end of center pin stretched into the rotor, the rear end cap is worn out to the other end, and was fixed through the plastics support, the one end of pivot stretch into in the plastics support with well spindle connection, the other end passes output gear and ball bearing in proper order, wears out the apron at last, is clearance fit between ball bearing and the apron, is interference fit between ball bearing and the pivot. The utility model discloses improve on output shaft support parts and bearing structure, not only changed the motor shaft to, radially change too big characteristics, changed the force distribution of output shaft moreover, the wearing and tearing that have alleviateed the vulnerable part have prolonged the life of motor number times.
Description
Technical field
This utility model is related to a kind of automatic adjustable ball bearing permanent magnetic step motor, belongs to motor technology neck
Domain.
Background technology
At present, permanent magnetism decelerating step motor uses plastics blowout patche, and this kind of electric machine structure shortcoming is：1）Axial float
Greatly, the axial mechanical location of load parts changes greatly；2）Output shaft is big with load circular runout, and over time can not
Disconnected increase；3）Short life, especially with life-span average out to 1000 hours.
Utility model content
In order to overcome the shortcomings of current permanent magnetism decelerating step motor, this utility model provides a kind of automatic adjustable rolling
Pearl bearing permanent magnetic step motor.
The technical solution of the utility model is as follows：
A kind of automatic adjustable ball bearing permanent magnetic step motor, described motor include rotor, stator, central shaft, rotating shaft,
Drive end bearing bracket, rear end cap, cover plate, plastic stent, output gear, ball bearing；
Described drive end bearing bracket is fixedly connected with stator respectively with rear end cap, and described rotor is located between drive end bearing bracket and rear end cap,
Internal rotor is stretched in one end of described central shaft, and the other end passes rear end cap, is fixed by plastic stent；One end of described rotating shaft
Stretch in plastic stent and be connected with central shaft, the other end sequentially passes through output gear and ball bearing, finally passes cover plate, described
It is gap cooperation between ball bearing and cover plate, be interference fit between described ball bearing and rotating shaft.
O-shaped ripple pad is set between above-mentioned ball bearing and cover plate.
The beneficial effect that this utility model is reached：
This utility model supports in output shaft and improves on part and supporting construction, not only changes motor axial direction, footpath
To the excessive feature of change, and change the distribution of force of output shaft, the abrasion alleviating consumable accessory extends motor several times
Service life, saved resource for society, user, it is to avoid waste.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.Following examples are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in figure 1, a kind of automatic adjustable ball bearing permanent magnetic step motor, motor includes rotor 3, stator 4, center
Axle 5, rotating shaft 7, drive end bearing bracket 1, rear end cap 2, cover plate 11, plastic stent 6, output gear 8, ball bearing 9；
Drive end bearing bracket 1 is fixedly connected with stator 4 respectively with rear end cap 2, and rotor 3 is located between drive end bearing bracket 1 and rear end cap 2, in
One end of heart axle 5 is stretched into inside rotor 3, and the other end passes rear end cap 2, fixing by plastic stent 6；One end of rotating shaft 7 is stretched into
It is connected with central shaft 5 in plastic stent 6, the other end sequentially passes through output gear 8 and ball bearing 9, finally pass cover plate 11, rolling
It is gap cooperation between pearl bearing 9 and cover plate 11, be interference fit between ball bearing 9 and rotating shaft 7.
O-shaped ripple pad 10 is set between above-mentioned ball bearing 9 and cover plate 11.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement can also be made and deform, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
