Description
Technical field
The utility model relates to a kind of machine shaft and yoke hot jacket positioner.
Background technology
Motor is mainly by casing, stator, rotor and the yoke composition be set in outside rotor, yoke mainly plays the effect of shielding electromagnetism, for a motor, the quality of yoke and the sealing between yoke with motor shaft are vital with being connected, present machine shaft and yoke are all generally be connected by the mode of hot jacket, when being socketed, energy and the cost of cost are larger, and, after socket, gap is left between machine shaft and yoke, during motor Long-Time Service, a lot of dusts will be overstock between machine shaft and yoke, the performance of motor is changed.
Utility model content
Defect existing when the purpose of this utility model is to solve that in prior art, machine shaft is connected with yoke, provides a kind of machine shaft and yoke hot jacket positioner.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of machine shaft and yoke hot jacket positioner, comprise machine shaft and be set in the yoke outside machine shaft, the outer peripheral face of described machine shaft is provided with multiple steady pin, and the inner peripheral surface of described yoke is provided with the fixing hole corresponding with described steady pin;
Described machine shaft and the sheathed open end of yoke are provided with dust-proof self-locking structure, this dust-proof self-locking structure comprises the elastic hook being arranged on described machine shaft end, the port of described yoke is provided with the groove corresponding with described elastic hook, and described elastic hook extend into the contact internal walls with groove in groove.
Above-mentioned machine shaft and yoke hot jacket positioner, after described machine shaft hot jacket, the steady pin on machine shaft extend in the fixing hole of yoke inner peripheral surface.
Above-mentioned machine shaft and yoke hot jacket positioner, described steady pin is circumferentially arranged on the surface of machine shaft.
The beneficial effects of the utility model are: the outer peripheral face of machine shaft is provided with multiple steady pin, the inner peripheral surface of yoke is provided with the fixing hole corresponding with steady pin, circumference is carried out to yoke locate by coordinating of steady pin and fixing hole, during socket, convenient and swift; The elastic hook of machine shaft end, the port of yoke is provided with the groove corresponding with elastic hook, elastic hook extend into the contact internal walls with groove in groove, and what elastic hook prevented dust to enter into machine shaft and yoke effectively coordinates between gap, makes the performance of motor more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A district enlarged drawing in Fig. 1.
Embodiment
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of machine shaft and yoke hot jacket positioner, comprise machine shaft 1 and be set in the yoke 2 outside machine shaft 1, the outer peripheral face of machine shaft 1 is provided with multiple steady pin 3, steady pin 3 is circumferentially arranged on the surface of machine shaft 1, and the inner peripheral surface of yoke 2 is provided with the fixing hole corresponding with described steady pin;
Machine shaft 1 open end sheathed with yoke 2 is provided with dust-proof self-locking structure, this dust-proof self-locking structure comprises the elastic hook 4 being arranged on machine shaft 1 end, the port of yoke 2 is provided with the groove 5 corresponding with elastic hook 4, and elastic hook 4 extend into the contact internal walls with groove 5 in groove 5.
In the utility model, after machine shaft 1 hot jacket, the steady pin 3 on machine shaft 1 extend in the fixing hole of yoke 2 inner peripheral surface.
The outer peripheral face of machine shaft 1 is provided with multiple steady pin 3, and the inner peripheral surface of yoke 2 is provided with the fixing hole corresponding with steady pin 3, is carried out circumference located by coordinating of steady pin 3 and fixing hole yoke 2, during socket, convenient and swift; The elastic hook 4 of machine shaft 1 end, the port of yoke 2 is provided with the groove 5 corresponding with elastic hook 4, elastic hook 4 extend into the contact internal walls with groove 5 in groove 5, what elastic hook 4 prevented dust to enter into machine shaft 1 and yoke 2 effectively coordinates between gap, makes the performance of motor more stable.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
