Abstract

The utility model relates to a bearing, in particular to a bearing with threads on an inner ring and an outer ring. The bearing with the threads on the inner ring and the outer ring comprises the outer ring (2), a rolling body (3) and the inner ring (4), wherein the rolling body (3) is arranged between the outer ring (2) and the inner ring (4), external threads (1) are arranged on an external face of the bearing outer ring (2), and internal threads (5) are arranged on an internal face of the bearing inner ring (4). Due to the facts that the threads are respectively arranged on the outer ring and the inner ring, the bearing is connected with a bearing set through the external threads arranged on the outside of the outer ring and connected with a shaft through the internal threads arranged on the inside of the inner ring, then the inner ring and the outer ring of the bearing are fixed through a circular ring provided with externals threads outside and nuts. Thus, the bearing with the threads on the inner ring and the outer ring effectively solves the technical problem that connection is not firm in the prior art and achieves stable and firm connection of the bearing.

Description

A kind of Internal and external cycle has the bearing of screw thread

[technical field]

The utility model relates to a kind of bearing, especially relates to the bearing that a kind of Internal and external cycle has screw thread.

[background technique]

Commercially available bearing main body structure is outer ring, inner ring, rolling element and retainer at present, and bearing inner race and axle sleeve connect, and the outer ring exterior face of bearing is through interference fit coupling shaft bearing; Or groove and injection moulding nylon are set in the outer ring of bearing, realize the fixing of bearing by nylon; Because bearings mounted a lot of places need antiwhip higher, so the existing bearing structure is difficult to realize.

[summary of the invention]

In order to overcome the deficiency in the background technique; The utility model discloses a kind of Internal and external cycle and have the bearing of screw thread; Described Internal and external cycle has the bearing of screw thread, through the outside outside thread coupling shaft bearing in outer ring, the internal thread coupling shaft of inner ring inner face; Overcome existing technology effectively and connected unstable technical problem, realized the firm connection of bearing.

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

A kind of Internal and external cycle has the bearing of screw thread, comprises outer ring, rolling element and inner ring, and rolling element is arranged between outer ring and the inner ring, is provided with outside thread at the exterior face of bearing outer ring, is provided with internal thread in the inside face of bearing inner race.

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

The described Internal and external cycle of the utility model has the bearing of screw thread; Through outer ring and inner ring are provided with screw thread respectively; By the outside outside thread coupling shaft bearing in outer ring, the internal thread coupling shaft of inner ring inner face is then through having the inner ring and the outer ring of externally threaded annulus and nut rigid bearing with the outside; Overcome existing technology effectively and connected unstable technical problem, realized the firm connection of bearing.

[description of drawings]

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

Fig. 2 is that the A of Fig. 1 is to diagrammatic sketch;

Among the figure: 1, outside thread; 2, outer ring; 3, rolling element; 4, inner ring; 5, internal thread.

[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;

The bearing that has screw thread in conjunction with accompanying drawing 1, the Internal and external cycle described in 2; Comprise outer ring 2, rolling element 3 and inner ring 4; Rolling element 3 is arranged between outer ring 2 and the inner ring 4, is provided with outside thread 1 at the exterior face of bearing outer ring 2, is provided with internal thread 5 in the inside face of bearing inner race 4.

Implement the bearing that the described Internal and external cycle of the utility model has screw thread; 2 outer side surface is set to outside thread 1 in the outer ring; Be connected with bearing support by outside thread 1 with screw thread; Utilize threaded collar locking then, the internal thread 5 of inner ring 4 connects with the axial filament with screw thread and by nut check, guarantees the balance of bearing when running up.

Claims

1. an Internal and external cycle has the bearing of screw thread; Comprise outer ring (2), rolling element (3) and inner ring (4); Rolling element (3) is arranged between outer ring (2) and the inner ring (4); It is characterized in that: the exterior face at bearing outer ring (2) is provided with outside thread (1), is provided with internal thread (5) in the inside face of bearing inner race (4).
