Abstract
The utility model relates to a contactless type sealing one-way thrust angular contact ball bearing. Both ends of an open type one-way thrust angle contact ball bearing are additionally provided with seal structures, and lubricating grease is sealed in the bearing. A seal groove is arranged on an outer ring (1), and an inner ring (2) is provided with a sealing blocking edge. Sealing rings (3), (4) are respectively fastened in the seal groove of the outer ring (1), a tiny radial gap is arranged between the sealing rings and the inner ring (2), and the contactless state is kept. The sealing ring (3), (4) are supported by a framework. Because both of the two ends are additionally provided with the seal structures, the lubricating grease is sealed in the bearing. The lubricating grease can not leak, and the utility model has the advantages of good sealing effect and low noise, and prevents dust, cutting fluid and other impurities from entering the inner part of the bearing, and the service life of the bearing is extended. The tiny radial gap is arranged between the sealing rings and the inner ring, and the contactless state is kept. Thus, the favorable sealing effect of the bearing in the process of rotation can be ensured, and the favorable high speed performance of the bearing can be ensured.
Description
Technical field:
The utility model relates to design bearing and manufacturing technology field, especially a kind of noncontact seal unilateral thrust angular contact ball bearing.
Background technique:
At present, the unilateral thrust angular contact ball bearing generally is used for the supporting of lathe ball-screw, and this bearing adopts the grease lubrication mode more, and because of lubricating grease thickness comparatively, film strength is higher, can bear bigger load, and does not run off.Because it is disposable lifelong lubricated that grease lubrication mostly is, and promptly when main frame assembles, to an amount of lubricating grease of the disposable adding of bearing, generally is no more than 1/2nd of bearing space, no longer adds lubricating grease in the main frame using process basically.Therefore, require the unilateral thrust angular contact ball bearing to want good seal, it is lubricated fully to guarantee that like this bearing obtains in whole using process, and stops dust, cutting fluid and other impurity to enter bearing inside.And existing unilateral thrust angular contact ball bearing is for the open bearing of sealing configuration, the inefficacy easy to wear of this bearing, and operating life is shorter.In addition, along with the development of High Speed Computerized Numerical Control Machine Tools, the also corresponding raising of the rotating speed of ball screw, corresponding bearing structure also should satisfy the demand of speed up.
Summary of the invention:
The deficiency that existing unilateral thrust angular contact ball bearing is easy to wear in order to overcome, the life-span is short, the utility model provides a kind of noncontact seal unilateral thrust angular contact ball bearing, and this bearing seal is effective, and noise is little, long working life, and suitable running up.
For achieving the above object, the utility model adopts following technological scheme:
This noncontact seal unilateral thrust angular contact ball bearing, sealing configuration has been set up at two ends at open type unilateral thrust angular contact ball bearing, has seal groove on the outer ring, and inner ring is provided with the sealing rib, two seal rings are fastened on respectively in the seal groove of outer ring, and keep contactless state with inner ring.
This noncontact seal unilateral thrust angular contact ball bearing, its seal ring can adopt rubber material, and the band skeleton supporting.
This noncontact seal unilateral thrust angular contact ball bearing, its rolling element can adopt silicon nitride ceramic material.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
Owing to increased sealing configuration at the bearing two ends, in bearing inside, lubricating grease does not run off with sealed in grease, and good sealing effect, noise are low, have stoped dust, cutting fluid and other impurity to enter bearing inside, has prolonged bearing working life.Small radial internal clearance is arranged between seal ring and the inner ring, keep contactless state, can guarantee like this has good sealing effect in the rotary course of bearing, can guarantee that again bearing has good high speed performance.
Description of drawings:
Fig. 1 is the structural representation of noncontact seal unilateral thrust angular contact ball bearing.
Among the figure: the 1-outer ring; The 2-inner ring; The 3-seal ring; The 4-seal ring; The 5-rolling element; The 6-retainer.
Specific embodiment:
As shown in fig. 1: sealing configuration has been set up at the two ends at open type unilateral thrust angular contact ball bearing, with sealed in grease in bearing inside.The outer ring has seal groove on (1), and inner ring (2) is provided with the sealing rib, and seal ring (3) and (4) are fastened on respectively in the seal groove of outer ring (1), and and inner ring (2) between small radial internal clearance is arranged, keep contactless state; Seal ring (3) and (4) are by skeleton supporting.
When bearing working, inner ring (2) drives rolling element (5) and the rotation of retainer (6) assembly, the outer ring keeps relative motionless with seal ring (3) and (4), seal ring (3) and (4) remain contactless state with inner ring (2) in the bearing rotary course, guarantee both to have kept good sealing effect, can guarantee that again bearing has good high speed performance with inner ring (2).
This bearing outer ring (1), inner ring (2) and rolling element (5) can adopt the manufacturing of high-quality Bearing Steel; Its rolling element (5) also can adopt silicon nitride ceramic material; Rubber material can be adopted in seal ring (3) and (4), and retainer (6) can adopt the engineering plastics manufacturing.
Claims (3)
1, a kind of noncontact seal unilateral thrust angular contact ball bearing, it is characterized in that: sealing configuration has been set up at the two ends at open type unilateral thrust angular contact ball bearing, the outer ring has seal groove on (1), inner ring (2) is provided with the sealing rib, two seal rings (3) and (4) are fastened on respectively in the seal groove of outer ring (1), and keep contactless state with inner ring (2).
2, noncontact seal unilateral thrust angular contact ball bearing as claimed in claim 1, it is characterized in that: rubber material can be adopted in seal ring (3) and (4), and the band skeleton supporting.
3, noncontact seal unilateral thrust angular contact ball bearing as claimed in claim 1, it is characterized in that: rolling element (5) can adopt silicon nitride ceramic material.
