Abstract
The utility model discloses a self-aligning combined bearing and relates to the technical field of micromotors. The combined bearing comprises a bearing bush 3 and a ball bearing 2, wherein the bearing bush 3 is a ball table with a spherical table surface, and a step through hole 5 is formed in the spherical table surface; the ball bearing 2 is embedded into the step through hole 5. The combined bearing has the characteristics of simple structure, convenience for processing, self-aligning function and the like, and is suitable for the micromotors used in equipment with the requirements of higher rotary speed, longer service life and lower noise.
Description
Technical field
The utility model relates to the combination bearing of micromachine technical field, particularly a kind of self-aligning.
Background technique
In prior art, in Miniature ball bearing electric machine, the bearing at two ends is to adopt ball bearing, because its rotating speed is higher, thereby, require the concentricity of two ends ball bearing higher, and then require the accuracy of manufacturing of two end supports higher, thereby improved the manufacture cost of product.Chinese patent (application number is 01220294964.8) " aligning support of a kind of fixedly low-power machine rotating shaft ", comprise support (1), there is a through hole at the axis place of this support, settle in this through hole one can be enclosed within shape on machine shaft (5) as the cup scholar (2) of abacus bead shape, this glass of scholar outside is wrapped in a cotton circle of oil (4), also comprise that one is pressed in the gland (3) in through hole by cup scholar, the inwall of described through hole is divided into successively the diameter that is connected by little and large first, second, the 3rd step, wherein the sidewall of first step surrounds one coniform, for cup scholar described in support, it is one cylindric that the sidewall of second step surrounds, for laying the cotton circle of described oil, it is one cylindric that the sidewall of the 3rd step surrounds, for gland described in clamping, described cup scholar is glanded and is pressed on first step.Compared with prior art, the utility model surface of contact is little, and surface friction drag is little, easy to lubricate, it is little to wear and tear, aligning speed is fast, has wide market prospects.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to process, bearing that can self-aligning.
For realizing its object, technical solution adopted in the utility model is the combination bearing of a kind of self-aligning of design: be to consist of bearing housing 3 and ball bearing 2; Described bearing housing 3 is billiard table, and its outside is spherical shape, has ladder hole 5 on its playing surface of the table, and described ball bearing 2 is inlaid in ladder hole 5.
The combination bearing of self-aligning of the present utility model, that sliding bearing and ball bearing are combined into one, that is: adopt the bearing housing of a billiard table shape, the outside of this bearing housing is spherical shape, and have ladder hole on its playing surface of the table, ball bearing is inlaid in the ladder hole of bearing housing, forms combination bearing.After installation, because the outer spherical surface of bearing housing and the coned face of bracket bearing chamber are that line contacts cooperation, thereby bearing housing can swing to all directions with ball bearing, thereby, realize self-aligning.Meanwhile, the structure of bearing housing is fairly simple, therefore its processing is particularly convenient.
Accompanying drawing explanation
Accompanying drawing 1 is main cross-sectional schematic of the present utility model.
In figure: the 1st, motor shaft, the 2nd, ball bearing, the 3rd, bearing housing, the 4th, outer spherical surface, the 5th, ladder hole.
Embodiment
Below in conjunction with embodiment, the utility model is further described.Explanation is below the mode exemplifying, but protection domain of the present utility model is not limited to this.
The combination bearing of the self-aligning of the present embodiment, to be formed by ball bearing 2 and bearing housing 3, bearing housing 3 forms the billiard table of (being generally to be dissectd by hemisphere) for spheroid dissects, its cutting plane has with cutting plane and is vertical ladder hole 5, and the non-cutting plane on bearing housing 3 (that is: outer spherical surface 4) still keeps spherical shape; Ball bearing 2(embeds) be arranged in the ladder hole 5 of bearing housing 3.
During assembling, ball bearing 2 is sleeved on to motor shaft 1, then, ball bearing 2 is packed in the ladder hole 5 of bearing housing 3, and allow the outer spherical surface 4 of bearing housing 3 be placed in the bearing chamber of support (not shown in FIG.).Because bracket bearing chamber is coned face, thereby the outer spherical surface 4 of bearing housing 3 is that line contacts cooperation with the coned face of bracket bearing chamber, thereby bearing housing 3 can swing to all directions with ball bearing 2, thereby, realize self-aligning.
The combination bearing of self-aligning of the present utility model, in micromachine, be to use in pairs, in installation or using process, when there is deviation in the axis of two ends ball bearing, the bearing housing at two ends will rotate in support separately, make both axis be tending towards overlapping, thereby, realize self-aligning.
The combination bearing of self-aligning of the present utility model, is applicable to require the micromachine that rotating speed is higher, the life-span is long, equipment that noise is lower is used.
Claims (1)
1. a combination bearing for self-aligning, is characterized in that: be to consist of bearing housing (3) and ball bearing (2); Described bearing housing (3) is billiard table, and its outside is spherical shape, has ladder hole (5) on its playing surface of the table, and described ball bearing (2) is inlaid in ladder hole (5).
