Abstract

The utility model relates to a rolling bearing. The utility model is mainly characterized in that the utility model is composed of an inner ring, an outer ring, a rolling body (a rolling ball or a roller) and a holder, wherein, the outer ring (or the inner ring) has a separate structure; the separate surfaces of the separate structure are fixedly and integrally connected through screw threads or a pin type screw bolt having a positioning function. The utility model effectively overcomes the disadvantage that when any part of a traditional integral rolling bearing is damaged, a new bearing needs replacing, and a bearing part can be repeatedly used by replacing a damaged part; the utility model has the advantages of energy saving, obvious maintenance cost reduction and bearing service life extension; in addition, the damage degree of the bearing can be visually observed in the process of maintenance, which is convenient for decision.

Description

A kind of rolling bearing

Technical field the utility model relates to a kind of rolling bearing.

Background technique when there is defective in concealment parts such as bearing a certain position, particularly rolling element (steel ball or roller) and retainer, is not easy to observe in traditional integrated type rolling bearing, can make the very fast damage of bearing like this in running; And when a certain position of bearing is damaged, can only solve by more renewing bearing, only be that the bearing that a position is damaged has just been scrapped, like this, not only cause the raising of user's maintenance expenses, also cause the waste of bearing material simultaneously.The utility model has proposed a kind of rolling bearing that can split at the shortcoming of traditional integrated type rolling bearing, has solved the defective that the integrated type rolling bearing exists.

Model utility content the utility model major character is to be made up of inner ring, outer ring, rolling element (ball or roller) and retainer, wherein outer ring (or inner ring) is the split-type structure, and be by screw thread or the pin formula bolt that has a positioning action that the affixed one-tenth of its fractionation face is whole.The utility model has effectively overcome any one position of traditional integrated type rolling bearing existence and has damaged the shortcoming that all must more renew bearing, by changing damaged location bearing parts can be reused.Have energy saving, significantly reduce maintenance expenses, prolong the bearing advantage in working life.And can in maintenance process, observe the damaged condition of bearing intuitively, convenient decision-making.

Be split as example with bearing outer ring below, in conjunction with the accompanying drawings the utility model made specific description:

Fig. 1 is the sectional drawing of citation form of the present utility model.

Fig. 2 is the side view of citation form of the present utility model.

Fig. 3 is the sectional drawing of the affixed form of thread type of the present utility model.

Fig. 4 is the side view of the affixed form of thread type of the present utility model.

Fig. 5 is the sectional drawing of the affixed form of pin formula of the present utility model.

Fig. 6 is the side view of the affixed form of pin formula of the present utility model.

In citation form Fig. 1, Fig. 2,1 is the outer ring, and 2 is inner ring, and 3 is ball, and 4 is retainer, and 5 are fractionation face.On outer ring (1), by fractionation face (5) with outer ring (1) dimidiation, any one assembly that splits rear bearing just respectively is integral, can change any one or a plurality of assembly in inner ring, outer ring, rolling element and the retainer, be integrated by the affixed bearing that makes that divides semi outer rings (1) then.

Bearing splits the affixed form of face affixed two kinds of the affixed and pin of screw thread.

Fig. 3, Fig. 4 are the affixed form figure of thread type: 1 is the outer ring, and 2 is inner ring, and 3 is ball, and 4 is retainer, and 5 is thread joint face, and 6 is locking key, and 7 are locking key locking double-screw bolt.In the affixed form of screw thread, by screwing of thread joint face (5), affixed with dividing outer ring (1) partly to carry out, the outer rim of (1) is provided with symmetrical 2 locking keys (6) in the outer ring then, prevents that screw thread is loosening when bearing irregular operating state.On locking key (6), 1-2 locking double-screw bolt (7) is set, in order to fixing, prevent that locking key (6) from moving at axial position.

Fig. 5, Fig. 6 are the affixed form figure of pin formula: 1 is the outer ring, and 2 is inner ring, and 3 is ball, and 4 is retainer, and 5 is the seam junction surface, and 6 is pin, and 7 is hexagon socket head cap screw.In the affixed form of pin formula, divide outer ring (1) partly to engage by seam junction surface (5), 2 pins (6) of symmetry are set in outer ring (1), be used for determining the position of branch semi outer rings (1).The end of pin (6) has a stop plush copper, prevents to rotate and axial displacement.The front end of pin (6) forms with hexagon socket head cap screw (7) and is threaded, and is affixed by the fastening outer ring (1) that makes of the two.

Claims

1, a kind of rolling bearing comprises the inner ring, outer ring, rolling element (ball or roller) and the retainer that fit together, it is characterized in that outer ring (or inner ring) is the split-type structure.

2, bearing according to claim 1 is characterized in that the affixed by the realization that is threaded of outer ring (or inner ring) split-type structure.

3,, it is characterized in that the outer rim (or inner edge of inner ring) of outer ring has locking groove, locking key, and fix by lock bolt according to claim 1,2 described bearings.

4, bearing according to claim 1 is characterized in that degree of lip-rounding formula till the split-type structure of outer ring (or inner ring).

5,, it is characterized in that the affixed of outer ring (or inner ring) split-type structure is to realize by the pin formula bolt that has positioning action according to claim 1,4 described bearings.
