Abstract
The utility model relates to a shaded-pole motor with a silica gel bearing sheath, which mainly comprises a front end cover, a rear end cover, a stator, a rotor and a rotating shaft. A ball bearing is respectively arranged at both ends of the rotating shaft; a silica gel bearing sheath is arranged between the ball bearing and the inner wall of the front end cover; and a silica gel bearing sheath is arranged between the ball bearing and the inner wall of the rear end cover. A ladder through hole is arranged in the silica gel bearing sheath, and positioning steps are formed in the connecting positions of ladders; and an annular slot hole is arranged on the end surface of the silica gel bearing sheath. Knurlings are uniformly distributed on the external circumference of the silica gel bearing sheath. The shaded-pole motor has the advantages that firstly, the shaded-pole motor can be automatically adjusted within a certain scope without tolerance with high precision, and an aluminum die-casting end cover is not required to be processed by a lathe machine, thereby saving the cost; secondly, the hardness of materials is changed during the assembling process of the bearing, and the noise and the vibration are reduced; thirdly, the temperature constant confining force can be provided for connecting pieces with different expansion coefficients under extensive operating temperature; and fourthly, the friction loss can be reduced.
Description
Technical field
The utility model relates to machine field, mainly is a kind of motor with cup rotor with silica gel bearing sheath.
Background technology
The bearing of original machine shaft outside is directly to contact with end cap, and end cap needs Vehicle Processing, and several parts need high-precision tolerance, and noise and vibration were bigger when motor rotated.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, and a kind of motor with cup rotor with silica gel bearing sheath is provided.
The utility model solves the technical scheme that its technical problem adopts: the motor with cup rotor of this band silica gel bearing sheath, mainly comprise front end housing, rear end cap, stator, rotor and rotating shaft, two ends in rotating shaft are equipped with ball bearing, between the inwall of ball bearing and front end housing, be provided with silica gel bearing sheath, between the inwall of ball bearing and rear end cap, be provided with silica gel bearing sheath.
Have ladder hole in the described silica gel bearing sheath, and form positioning step, on the end face of silica gel bearing sheath, have the slotted eye of annular in the ladder junction.
Uniform annular knurl on the external peripheral surface of described silica gel bearing sheath.
The effect that the utility model is useful is: 1, can adjust automatically within the specific limits, not need high-precision tolerance, aluminium die casting end cap does not need Vehicle Processing, has saved cost; Material hardness when 2, changing the bearing assembling, and reduce noise and vibration; 3, can under working temperature on a large scale, provide the confining force of Wen Ding for the connector of the different coefficients of expansion; 4, reduce friction loss.

Description of reference numerals: front end housing 1, rear end cap 2, stator 3, rotor 4, rotating shaft 5, silica gel bearing sheath 6, slotted eye 6-1, positioning step 6-2, annular knurl 6-3, ball bearing 7.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in the figure, the motor with cup rotor of this band silica gel bearing sheath, mainly comprise front end housing 1, rear end cap 2, stator 3, rotor 4 and rotating shaft 5, two ends in rotating shaft 5 are equipped with ball bearing 7, between the inwall of ball bearing 7 and front end housing 1, be provided with silica gel bearing sheath 6, between the inwall of ball bearing 7 and rear end cap 2, be provided with silica gel bearing sheath 6.
Have ladder hole in the described silica gel bearing sheath 6, and at ladder junction formation positioning step 6-2, ball bearing 7 is installed in the ladder hole, and roof pressure is on positioning step 6-2, on the end face of silica gel bearing sheath 6, have the slotted eye 6-1 of annular, can compress a bit, stator has some deviations, and also it doesn't matter.Uniform annular knurl 6-3 on the external peripheral surface of described silica gel bearing sheath 6 increases axial friction, prevents axial endplay.
The decentraction problem of end cap and rotating shaft can be adjusted within the specific limits automatically by elasticity, does not need high-precision tolerance, and aluminium die casting end cap does not need Vehicle Processing, has saved cost.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
