Description

A kind of outer collar bearing

Technical field

This utility model belongs to field of bearings, a kind of outer collar bearing.

Background technology

Bearing be plant equipment for the indispensable parts of transmission, its effect mainly support rotating parts, it is achieved turn Dynamic component being rotatably assorted relative to fixed component, namely fixed rotating shaft makes it can only realize rotating, and control its axially and Movement radially.

But the bearing of part is when coordinating with portion inside part and external parts, be all that needs are supporting, i.e. the hole of inner ring The size of footpath just corresponding portion inside part, and the aperture of outer ring also just to coordinate the size of external parts, but some time Time is necessarily required to use bearing, but the size of portion inside part or external parts does not has and both supporting bearings, and both are not Can coordinate simultaneously, if removing to buy or manufacture the bearing of required size the most again, be delayed the substantial amounts of time, so The motility of this kind of bearing utilization is relatively low.

Utility model content

For the deficiencies in the prior art, this utility model provides a kind of mode utilizing multilamellar lasso, changes outer ring Size, make the peripheral diameter of outer ring just coordinate external parts, improve the motility that bearing uses, optimize the accessory of bearing The outer collar bearing of energy.

For achieving the above object, this utility model provides following technical scheme: a kind of outer collar bearing, including inner ring and Outer ring, is provided with retainer between inner ring and outer ring, retainer is provided with ball, it is characterized in that: be arranged with on described outer ring It is provided with several fixing screwed holes for bolt insertion on lasso, and described lasso and outer ring.

Further, described lasso is provided with several, and the described radially arranged distribution of several lassos.

Further, several screwed holes described are uniformly distributed circumferentially on lasso.

Further, on the circumference side of described lasso, the place of corresponding screwed hole offers for accommodating the recessed of bolt head Groove.

Further, the face, outer ring of described lasso offers several locating grooves, and described locating groove becomes center It is symmetrically distributed on lasso, the inner ring face of corresponding lasso is provided with the positioning convex strip fastened with locating groove.

Compared with prior art, the beneficial effects of the utility model are:

1, by several lassos, the setting of screwed hole, it is achieved continue the lasso of the suitable size of fit in the outside of outer ring, And make it fix by the cooperation of screwed hole and bolt, finally make the new outer ring of the bearing after being socketed just coordinate External parts pore size, improve the accessory performance of bearing and service efficiency, time-consuming and resource.

2, by the setting of groove, it is ensured that bolt head will not protrude from the surface of the outer layer of lasso, thus does not interferes with Outer layer coordinates with external parts, it is ensured that bearing and inside and outside relay part properly functioning.

3, by location figure bar and the setting of locating groove, convenient the most when mounted, between lasso and lasso and outer ring it Between the location of relative position, thus facilitate the installation of bolt, save the set-up time, improve the efficiency installed.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the embodiment of this utility model outer collar bearing is described further.

A kind of outer collar 5 bearing, including inner ring 1 and outer ring 2, is provided with retainer 3, retainer between inner ring 1 and outer ring 2 It is provided with ball 4 on 3, it is characterized in that: on described outer ring 2, be arranged with lasso 5, and if being provided with on described lasso 5 and outer ring 2 Dry fixing screwed hole 6 for bolt insertion.

The present embodiment is preferred, and described lasso 5 is provided with several, and several radially arranged distributions of lasso 5 described； And the present embodiment is that lasso 5 is provided with three.

The present embodiment is preferred, and several screwed holes 6 described are uniformly distributed circumferentially on lasso 5.

The present embodiment is preferred, and 2, the outer ring of described lasso 5 offers several locating grooves 8, and described locator card Groove 8 is in a center of symmetry to be distributed on lasso 5, and the inner ring 1 of corresponding lasso 5 is provided with and determining that locating groove 8 fastens The position preferred locating groove of raised line 9(8 is provided with four, but the present embodiment is provided with two).

When bearing uses, the portion inside part used and the aperture of external parts do not have together with the bearing matched, just This utility model bearing matched with portion inside part can be used, as when the aperture of external parts excessive, the diameter of outer ring 2 is not enough To match with external parts, it is possible to the lasso 5 of applicable thickness is sheathed on outer ring 2, (even if being suitable for thickness lasso 5 External diameter just coordinates the pore size of external parts) or the multiple lasso of fit 5, finally make the external diameter of outermost lasso 5 Just coordinate the aperture of external parts；After the lasso 5 of the complete suitable size of fit, utilize locating groove 8 and the cooperation of location figure bar, By lasso 5(or multilamellar lasso 5) the screwed hole 6 that aligns on outer ring 2 of screwed hole 6 be tightened with bolt；Finally make socket The new bearing outer ring 2 completed and the inner ring 1 external parts of corresponding matching and the pore size of portion inside part respectively, thus improve this reality By the service efficiency of novel bearing, use manpower and material resources sparingly；And work as bearing in use, because the centre symmetry of entirety makes Shaft strength is uniform, increases the service life.

The present embodiment is preferred, and on the circumference side of described lasso 5, the place of corresponding screwed hole 6 offers for accommodating spiral shell The groove 7 of bolt head.

Utilize groove 7 to accommodate bolt head, prevent head from protruding from 2, the outer ring of lasso 5, do not interfere with lasso 5 with external The cooperation of parts, improves the service efficiency of this utility model bearing.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
