Description
Technical field
The utility model is related to technical field of bearings, it particularly relates to a kind of linear bearing.
Background technology
At present, the species of bearing is relatively more, but the species of linear bearing is few, and the linear bearing that existing market occurs is all
It is relatively wide, it is necessary to take larger installing space, and heavier-weight, it is impossible to be applied to some special occasions and use.
Therefore, developing one kind can save installing space, and compact conformation, the linear bearing of lighter in weight is become as in the industry
The problem of personage's urgent need to resolve.
Utility model content
The utility model proposes a kind of linear bearing, the deficiency of above-mentioned aspect in existing product is overcome.
The purpose of this utility model is achieved through the following technical solutions：
A kind of linear bearing, including bearing outer ring, retainer and ball, if being evenly equipped with the circumferencial direction of the retainer
Dry projection, the thickness that projection radially goes up is less than the sphere diameter of the ball, and is provided with the projection and can coat the rolling
The ball of pearl, is provided with annular groove on the inside of the bearing outer ring, arc surface corresponding with the ball, institute are provided with the annular groove
State minimum distance of the central shaft of retainer away from any ball with axle to be mounted radius it is corresponding.
Further, the retainer is put together by retainer one and retainer two.
Further, the retainer one and retainer two are symmetrical on face, and the plane of symmetry is perpendicular to the axial direction side of retainer
To and the centre of sphere point of all ball be respectively positioned on the plane of symmetry.
The beneficial effects of the utility model are：Installing space, compact conformation, lighter in weight can be saved.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in figures 1 to 6, a kind of linear bearing according to the utility model embodiment, including bearing outer ring 1, holding
Frame 2 and ball 3, are evenly equipped with some projections on the circumferencial direction of the retainer 2, the thickness that the projection radially goes up is small
Being provided with the sphere diameter of the ball 3, and in the projection can coat the ball 4 of the ball 3, and the inner side of the bearing outer ring 1 is set
Have annular groove 5, be provided with the annular groove 5 with the corresponding arc surface of the ball 3, the central shaft of the retainer 2 is away from any ball 3
Minimum distance with axle to be mounted radius it is corresponding.
In a specific embodiment of the present utility model, the retainer 2 is by retainer one and the split of retainer two
Into.
In a specific embodiment of the present utility model, the retainer one and retainer two are symmetrical on face, symmetrically
Face is respectively positioned on the plane of symmetry perpendicular to the axial direction of retainer 2 and the centre of sphere point of all ball 4.
Above-mentioned technical proposal of the present utility model is understood for convenience, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
Semicircular projection is provided with retainer one and retainer two, manufacturing process uses compressing technique, will
After retainer one and the split of retainer two, two semicircular projections piece together a projection for circle, and ball is provided with projection
Hole 4, the sphere diameter of ball 4 is more bigger than the sphere diameter of ball 3, and ball 3 can be rolled but cannot departed from from ball 4 in ball 4.
Single ball 3 as bearing rolling element, ball 3 wrapped ball 3 by retainer 2, and ball 3 can be in ball
Rolled in 4, but will not departed from from retainer 2, ball 3 and retainer 2 are installed in the interior of the bearing outer ring 1 for having internal annular groove 5
Side, so as to form a kind of ball linear bearing.
When mounted, first be positioned over ball 3 on retainer one by ball 3, and retainer two then is fastened on into retainer one
On, and be fixed together using forms such as welding, colligation and buckles.
From unlike existing bearing, this programme does not have bearing inner race to this programme, and ball 3 directly connects with an axle to be mounted
Touch, when in use, axle can move linearly along the axial direction of bearing outer ring 1.
In sum, by above-mentioned technical proposal of the present utility model, installing space can be saved, compact conformation, weight compared with
Gently.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every with same as the present application or phase
Approximate technical scheme, all falls within protection domain of the present utility model.
