Abstract

The utility model relates to a bearing, in particular to a bearing with a connection protruding sleeve in an inner ring. The bearing comprises an outer ring (1), a rolling body (2) and an inner ring (3), wherein the width of the inner ring (1) is at least 1.5-folded width of the outer ring (1), a surrounding outer channel is arranged on the outer surface of one side of the inner ring (3), and an inner channel is arranged at the middle part of the inner side surface of the outer ring (1); the inner channel of the outer ring (1) corresponds to the outer channel of the inner ring (3); the rolling body (2) is arranged between the inner channel and the outer channel; and the other side of the inner ring (3) is provided with a connection hole (4). According to the bearing with the connection protruding sleeve in the inner ring, disclosed by the utility model, one side of the inner ring is extended outwards, the connection hole is formed in the extended outer ring, and the inner ring of the bearing is fixed by a pin or a screw, and thus a situation that the inner ring of the bearing and a shaft slip is effectively prevented; and the bearing has the advantages of compact structure, reasonable design, convenience for machining and the like.

Description

A kind of inner ring has the bearing that connects the protrusion cover

[technical field]

The utility model relates to a kind of bearing, especially relates to a kind of inner ring and has the bearing that connects the protrusion cover.

[background technique]

Known, rolling bearing generally is made up of inner ring, outer ring, rolling element and retainer four parts, and the effect of inner ring is to match to merge with axle to rotate together with the axis; The outer ring effect is to be connected cooperation with bearing support, mainly plays playing a supportive role; Because the inner ring inner face of bearing and the interference fit that only relies on the inner ring inner face with axle being connected of axle, be easy to occur skidding of inner ring inner face and axle, cause bearing inner race or spool breakage.

[summary of the invention]

In order to overcome the deficiency in the background technique; The utility model discloses a kind of inner ring and have the bearing that connects the protrusion cover; The utility model is through stretching an epitaxial lateral overgrowth of inner ring; And on the outer ring of extending, attachment hole is set, by pin or screw bearing inner race, effectively overcome the generation of bearing inner race with the axle skidding.

For realizing the foregoing invention purpose, the utility model adopts following technological scheme:

A kind of inner ring has the bearing that connects the protrusion cover, comprises outer ring, rolling element and inner ring, and the width of inner ring is at least 1. 5 times of outer ring, a side exterior face of inner ring be provided with around outer channel, the inner side surface middle part of outer ring is provided with internal channel; The outer channel of the corresponding inner ring of the internal channel of said outer ring is provided with rolling element between internal channel and outer channel; The opposite side of inner ring is provided with attachment hole.

Described inner ring has the bearing that connects the protrusion cover, and the hole wall of said attachment hole is unthreaded hole or tapped hole.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The described inner ring of the utility model has the bearing that connects the protrusion cover through an epitaxial lateral overgrowth of inner ring is stretched, and on the outer ring of extending, attachment hole is set, and by pin or screw bearing inner race, has effectively overcome the generation of bearing inner race with the axle skidding; The utlity model has compact structure, reasonable in design, advantage such as easy to process.

[description of drawings]

Fig. 1 is the structural representation of the utility model;

Among the figure: 1, outer ring; 2, rolling element; 3, inner ring; 4, attachment hole.

[embodiment]

Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope;

Has the bearing that connects the protrusion cover in conjunction with the inner ring described in the accompanying drawing 1; Comprise outer ring 1, rolling element 2 and inner ring 3; The width of inner ring 3 is at least 1. 5 times of outer ring 1, a side exterior face of inner ring 3 be provided with around outer channel, the inner side surface middle part of outer ring 1 is provided with internal channel; The outer channel of the corresponding inner ring 3 of the internal channel of said outer ring 1 is provided with rolling element 2 between internal channel and outer channel; The opposite side projection of inner ring 3 is provided with attachment hole 4; The hole wall of said attachment hole 4 is unthreaded hole or tapped hole.

Implement the described inner ring of the utility model and have the bearing that connects the protrusion cover; The connection protrusion cover that the opposite side of inner ring 3 is set to give prominence to; The attachment hole 4 that projection is provided with is connected through pin or screw with axle, forms and is fixedly coupled form, has realized bearing inner race and the non-slip purpose of axle.
