Abstract
The utility model discloses a novel double-row angular contact ball bearing. The novel double-row angular contact ball bearing comprises an outer ring, an inner ring, a retainer and a steel ball, wherein the retainer is obliquely arranged, and an outer side of the retainer is higher than an inner side thereof; the height d of a flange of the bearing is equal to the diameter of the steel ball multiplying Kd/2, wherein Kd is a flange coefficient and is 0.6-0.75; a basic contact angle of the bearing is 40 degrees; an oil injection hole is formed in the outer ring. According to the novel double-row angular contact ball bearing, the deviation angle allowed by the running track of the steel ball is increased, the inclination of an axis of the inner ring of the bearing can be matched, and sharp wear between the steel ball and the flange is avoided, so that the service life of the bearing is prolonged.
Description
technical field:
The utility model relates to a kind of milling train two ends bearing, particularly relates to a kind of Novel double-row angular contact ball bearing.
background technique:
At present, roller-mill bearing is very general as thrust bearing with double-row angular contact bal bearing, and especially workroll bearing, generally selects four-line column roller bearing to bear radial load, and double-row angular contact bal bearing bears thrust load, does thrust bearing and uses.And double-row angular contact bal bearing structure generally has two kinds: 86000 types: two half inner rings; 156000 types: double semi outer rings; Size section is generally 100mm≤d≤440mm, and wrapping angle selects 40 ° substantially.
In actual production process, on work roll, conventionally can be applied in bending roller force, consistent to guarantee to roll the plate face thickness of plate.Bending roller force can make roll diameter of roller produce certain inclination, causes the run-off the straight of thrust bearing inner ring axis, produces and intersects with outer coil axis, and the track of steel ball running is also offset.In the time that instantaneous load increases, can cause steel ball running track to depart from raceway, reach the chamfering place of raceway and rib handing-over, steel ball and rib sharply wear and tear, and cause bearing heating, very fast locking, bearing is scrapped, and this phenomenon with very general in thrust bearing, has a strong impact on production and operation at roll.
model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, easy to use and avoid bearing steel ball running track to depart from the Novel double-row angular contact ball bearing of raceway.
The technical solution of the utility model is: a kind of Novel double-row angular contact ball bearing, contain outer ring, inner ring, retainer and steel ball, described retainer is obliquely installed, its outer side is higher than inner side edge, the rib height d=steel ball size × Kd/2 of bearing, wherein Kd represents rib coefficient, gets 0.6～0.75.
The basic wrapping angle of bearing is 40 °, on described outer ring, is provided with oil hole.The deviation angle α that steel ball running track allows is 3 °～10 °.
The beneficial effects of the utility model are:
1, the utility model has increased the deviation angle that steel ball running track allows, and can adapt to the inclination that bearing inner race axis occurs, and avoids steel ball and rib to produce sharply wearing and tearing, thereby has extended the working life of bearing.
2, the utility model retainer adopts and is obliquely installed, and its outer side, higher than inner side edge, can make the rib height of bearing increase, thereby effectively avoids steel ball derailing.
3, the utility model is reasonable in design, easy to use and the life-span is long, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing explanation:
Fig. 1 is the sectional view of Novel double-row angular contact ball bearing.
embodiment:
Embodiment: referring to Fig. 1, in figure, 1-outer ring, 2-inner ring, 3-retainer, 4-steel ball.
Novel double-row angular contact ball bearing contains outer ring 1, inner ring 2, retainer 3 and steel ball 4, and wherein: retainer 3 is obliquely installed, its outer side is higher than inner side edge, the rib height d=steel ball size × Kd/2 of bearing, and wherein Kd represents rib coefficient, gets 0.6～0.75.
The basic wrapping angle of bearing is 40 °, is provided with oil hole on outer ring, and Kd can choose 0.6,0.62,0.65,0.68,0.70,0.72 or 0.75 etc. as required.
The utility model has increased rib height (former design standard Kd gets 0.4～0.5), correspondingly increase the deviation angle α that steel ball running track allows, α is 3 °～10 °, can adapt to the inclination that bearing inner race axis occurs, avoid steel ball and rib to produce sharply wearing and tearing, thereby extended the working life of bearing.
The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction, and any simple modification that every foundation technical spirit of the present utility model is done, all still belongs in the scope of technical solutions of the utility model.
Claims (3)
1. a Novel double-row angular contact ball bearing, contains outer ring, inner ring, retainer and steel ball, it is characterized in that: described retainer is obliquely installed, its outer side is higher than inner side edge, the rib height d=steel ball size × Kd/2 of bearing, wherein Kd represents rib coefficient, gets 0.6～0.75.
2. Novel double-row angular contact ball bearing according to claim 1, is characterized in that: the basic wrapping angle of bearing is 40 °, on described outer ring, is provided with oil hole.
