Abstract
The utility model discloses a bearing positioning structure of a motor. The bearing positioning structure includes a stator, end caps, a bearing and a shaft. The shaft is a plain shaft. The shaft is arranged in an inner ring of the bearing. An outer ring of the bearing is arranged in holes of the end caps. The end caps are installed on two sides of the stator. By adopting the technical scheme in the utility model, the bearing positioning structure of the motor has beneficial effects of simple structure, simple processing technique, simple assembly technique, high working efficiency, convenient dismounting and convenient maintenance.
Description
Technical field
The utility model relates to a kind of motor that is used for medical pump, is specifically related to a kind of bearing location structure of motor.
Background technology
Move axially in order to prevent that bearing from producing when bearing axial load, bearing is all used axial direction positioning device with shell aperture on axle.The selection of bearing locate mode on axle and in the shell aperture is depended on to act on the size and Orientation that axle is gone up load, the rotating speed of bearing, the type of bearing, the position of bearing on axle etc.Axial load is big more, and the bearing rotating speed is high more, and axial location should be reliable more.For dissimilar bearings, the mode of axial location also should be different.
As shown in Figure 2, when we install the inner ring of bearing 13 on axle 14 at present, all by the shaft shoulder of axle 14 in the position of a rigid bearing 13, another side is then fixing with spring flange 15; When installed in the hole of end cap 12 outer ring of bearing 13, the inboard in the hole of end cap 12 was with the position of stop catch shoulder rigid bearing 13, and opposite side is with elastic scheibe 15 location.This locate mode requires the processing shaft shoulder and location notch on axle, processing stop catch shoulder in the hole of end cap, and processing technology is complicated, and assembly technology is complicated, when taking a lot of work, the dismounting trouble.
Need a kind of bearing location structure of motor, simple in structure, processing technology is simple for this reason, and assembly technology is simple, effectively increases work efficiency, and convenient disassembly is easy to maintenance simultaneously.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple in structure that the purpose of the utility model is to provide, and processing technology is simple, and assembly technology is simple, effectively increases work efficiency while convenient disassembly, the bearing location structure of motor easy to maintenance.
For achieving the above object; The technical scheme of the utility model is following: a kind of bearing location structure of motor; Comprise stator, end cap, bearing and axle, said axle is an optical axis, and said axle is arranged in the inner ring of said bearing; Said bearing outer ring is arranged in the hole of said end cap, and said end cap is installed in said stator both sides.
Preferably, said axle is an interference fit with said bearing inner race.
Preferably, the hole of said bearing outer ring and said end cap is an interference fit.
Adopt the beneficial effect of present technique scheme to be: simple in structure, processing technology is simple, and assembly technology is simple, effectively increases work efficiency, and convenient disassembly is easy to maintenance simultaneously.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment technology; To do to introduce simply to the accompanying drawing of required use in the embodiment technical description below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the prior art constructions sketch map.
The numeral corresponding component title represented among the figure with letter:
1. 14. 15. back-up rings of 4. 11. stators of stator 2. end caps, 3. bearings, 12. end caps, 13. bearings.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the embodiment of the utility model, a kind of bearing location structure of motor; Comprise stator 1, end cap 2, bearing 3 and axle 4, axle 4 is an optical axis, and axle 4 is arranged in the inner ring of bearing 3; Bearing 3 outer rings are arranged in the hole of end cap 2; End cap 2 is installed in stator 1 both sides, and axle 4 is an interference fit with bearing 3 inner rings, and the hole of bearing 3 outer rings and end cap 2 is an interference fit.Adopt optical axis, the Internal and external cycle interference fit.The outer ring magnitude of interference is 0.025 ㎜, and the inner ring magnitude of interference is 0 ㎜.
The bearing location structure of a kind of motor of the utility model; Concrete assembling process is following: end cap is placed on the anchor clamps; Seaming chuck through press is pressed into bearing outer ring in the end cap; Anchor clamps have guaranteed that bearing is pressed into the degree of depth in the end cap, and seaming chuck has guaranteed in bearing is pressed into the process of end cap, to have only bearing outer ring stressed, and retainer can not be damaged because of the interaction force between the Internal and external cycle; Bearing that presses and end cap are placed on the anchor clamps; Through press the inner ring of bearing is gone in axial compression, these anchor clamps have guaranteed that axial compression goes into the degree of depth of bearing inner race, when bearing inner race is gone in axial compression; Have only the inner ring of bearing stressed, retainer can not be damaged because of the interaction force between the Internal and external cycle.The location structure of the utility model need not processed the shaft shoulder and location notch on axle, need not process the stop catch shoulder in the end cap, makes the processing technology of axle and end cap simple.Directly be pressed into during assembling and get final product, go into the degree of depth through press and frock Control Shaft pressure-bearing; Internal and external cycle prevents moving axially of axle through interference fit.Whole assembly technology is simple, has improved operating efficiency greatly, and convenient disassembly, and is easy to maintenance.
Adopt the beneficial effect of present technique scheme to be: simple in structure, processing technology is simple, and assembly technology is simple, effectively increases work efficiency, and convenient disassembly is easy to maintenance simultaneously.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
