Abstract
The utility model provides a backing bearing comprising an outer bearing ring, an inner bearing ring and rollers, wherein the rollers are mounted between the outer bearing ring and the inner bearing ring, and are provided with dual holders; an inner circumferential surface of the outer bearing ring is provided with raceways for the rollers to roll, and stack rings on both sides thereof; both sides of end faces of the inner bearing ring are respectively provided with check rings which are provided with sealing ring grooves; the stack rings are arranged in the sealing ring grooves and in a clearance fit with the sealing ring grooves; and both sides of inner holes of the dual holders are provided as inverted tapered surfaces. The backing bearing is novel and ingenious in structural design, and improves assembly convenience and reliability and effectiveness of a seal structure.
Description
Technical field
The utility model relates to a kind of bearing, specifically a kind of multiple rollers cold calender and straightening machine back lining bearing.
Background technique
Back lining bearing is widely used on multiple rollers cold calender and the leveller equipment, is mainly used in the high precision rolling of steel and non-ferrous metal steel band, also can be used for other purposes, such as roller-type straightening machine or bender etc.Back lining bearing is the thick especially rolling bearing in outer ring, and being installed on the static axle with pattern in groups during use becomes back-up roll.Pressure on the work roll is delivered to back lining bearing and is sent to frame by the saddle system by intermediate roll.The structural type of back lining bearing has multiple, and according to the difference of structural type, back lining bearing can bear higher radial load, also can bear simultaneously by adjacent mechanism and be delivered to thrust load on the frame.
The main structure pattern of back lining bearing is biserial or three-row cylindrical roller bearing, is with retainer or is not with the full roller of retainer, and inner ring has one or multi-channel circular groove and several oilholes.For the double-row cylindrical roller back lining bearing that three ribs are arranged with the retainer outer ring, roller is guided by two brass retainers, and this structure is in assembly process, and rib is opened the circular groove of an assembling roller outside the outer ring of being everlasting, so that assembling.
How present back lining bearing is not with seal arrangement, and this structure causes the waste of lubricant grease on the one hand, because the leakage of lubricant grease might cause the pollution to rolled steel strip, affects quality of product on the other hand.Particularly the outer ring has the rib place of fitting recess, easily causes unbalanced stress to peel off, and also is unfavorable for the storage of grease.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of to prevent effectively that dust from entering in the bearing, saves simultaneously lubricant grease, back lining bearing easy to assembly.
The technical solution of the utility model is: comprise bearing outer ring, bearing inner race, roller; Roller is loaded between bearing outer ring, the bearing inner race; Roller is provided with two retainers; The inner peripheral surface of bearing outer ring is provided with the raceway that rolls for roller; Folded ring all is equipped with in bearing outer ring inner peripheral surface both sides; Bearing inner race end face both sides respectively are provided with a back-up ring; Back-up ring is provided with closure gasket groove; Folded ring places closure gasket groove; Folded ring is Spielpassung with closure gasket groove.
The inner peripheral surface both sides of described bearing outer ring are provided with left rib, right rib, and the centre is provided with centre rib; Left rib, right rib, centre rib are parallel to each other; Be rolling left of rolling for roller between left rib and the centre rib; Right raceway for rolling for roller between right rib and the centre rib; Two row rollers are loaded on respectively and roll left, right raceway.
Described left rib is provided with left folded ring; Described right rib is provided with right folded ring.
Described bearing inner race endoporus is provided with annular oil groove, oilhole.
Described annular oil groove is one, and oilhole is three.
The two ends of the endoporus of described pair of retainer are inverted cone surface.
The external diameter of described back-up ring is less than the internal diameter of bearing outer ring, greater than the external diameter of bearing inner race.
The beneficial effects of the utility model are: increased folded ring in the outside closure gasket groove of bearing two ends back-up ring, because folded ring outer rim contacts with the rib at bearing outer ring two ends, the annular groove in folded ring endoporus and the back-up ring outside leaves the gap.The configuration of back-up ring, closure gasket groove and folded ring has formed labyrinth sealing at the bearing two ends, can prevent effectively that dust from entering bearing inside, has guaranteed precision and the working life of bearing.On the other hand, can effectively stop the loss of lubricant grease in the bearing, improve lubrication effect.The inverted cone surface that the endoporus two ends of two retainers arrange can effectively make things convenient for the assembling of roller, needn't open at the rib of bearing outer ring the circular groove of assembling roller, has guaranteed the integrity of the rib of bearing outer ring.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, bearing outer ring, 2, left rib, 3, centre rib, 4, bearing inner race, 5, roller, 6, two retainer, 7, back-up ring, 8, closure gasket groove, 9, folded ring.
Embodiment
Among Fig. 1, the utility model comprises bearing outer ring 1, left rib 2, centre rib 3, right rib, bearing inner race 4, roller 5, two retainer 6, back-up ring 7, closure gasket groove 8, folded ring 9.Bearing outer ring 1 two ends are provided with left rib 2, right rib, and the middle part is provided with centre rib 3; Bearing inner race 4 endoporus are provided with one annular oil groove and three oilholes; Be provided with roller 5 between bearing outer ring 1 and the bearing inner race 4, roller 5 is provided with two retainers 6, the two ends of bearing inner race 4 end face both sides and roller 5 are provided with back-up ring 7, back-up ring 7 outer rims are established closure gasket groove 8, be provided with folded ring 9 in the closure gasket groove 8 of back-up ring 7 outer rims, the outer rim of folded ring 9 contacts with the left rib 2 at bearing outer ring 1 two ends, right rib, and the closure gasket groove 8 of folded ring 9 endoporus and back-up ring 7 outer rims leaves the gap; The endoporus two ends of two retainers 6 are inverted cone surface.
The closure gasket groove 8 that back-up ring 7 outer rims arrange and folded ring 9, formed labyrinth sealing at the bearing two ends, can prevent effectively that dust from entering in the bearing on the one hand, prolong the working life of bearing, can effectively preserve lubricant grease in bearing on the other hand, reduce the leakage of lubricant grease, improve the lubrication effect of bearing.The endoporus two ends of two retainers 6 are made as inverted cone surface, are conducive to the assembling of roller 5, have guaranteed the integrity of bearing outer ring two ends ribs.
The utility model structural design novelty is ingenious, total has guaranteed bearing in the situation of profile size constancy, has increased the effectively reliable of the facility of assembling and sealing configuration.
