Abstract
The utility model discloses a self-aligning roller bearing for vibration machinery, in particular to the self-aligning roller bearing which can bear huge vibration and impact loads and is applicable to various vibration machineries, which comprises an inner ring and an outer ring, wherein a holder is arranged between the inner ring and the outer ring, the holder is a single-leaf solid holder, axial pockets are evenly distributed on two sides, the pockets on two sides are crossly arranged, a roller is arranged in each pocket and is a waist drum shape spherical roller, the inner surface of the outer ring and an inner ring track which is corresponding to the roller are both spherical surfaces, and a circumferential boss is arranged in the middle of the outer side face of the holder. The self-aligning roller bearing is characterized in that the outer surface of the circumferential boss is the spherical surface and is slidingly engaged with the inner surface of the outer ring.
Description
Technical field
The utility model relates to a kind of roller bearing.Specifically, be the selfaligning roller bearing that can bear great vibrations and impact load, be applicable on the various vibrating machines.
Background technique
At present, the various roller bearings that mechanically use all are common roller bearings.This common roller bearing contains inner ring and outer ring, between inner ring and outer ring retainer is arranged, and this retainer is the monolithic entities retainer, and its both sides are evenly equipped with axial pocket hole, and cross-shaped layout between the pocket hole of both sides.In each pocket hole roller is arranged all, this roller is dolioform spherical roller.The internal surface of outer ring and be sphere with the corresponding inner ring raceway of roller.Be processed with circumferential boss in the middle of wherein the retainer inner side surface, be between the internal surface of this circumferential boss and inner ring internal surface and contact shape and be slidingly matched, guide retainer to move by inner ring.Because retainer directly contacts with vibrating bigger inner ring, retainer is very unstable between Internal and external cycle under the working state, makes retainer and roller damage easily.Therefore, the working life of this roller bearing is not long.
The model utility content
Problem to be solved in the utility model provides a kind of vibrating machine selfaligning roller bearing.This vibrating machine selfaligning roller bearing, long service life.
For addressing the above problem, take following scheme:
Vibrating machine of the present utility model comprises inner ring and outer ring with selfaligning roller bearing, between inner ring and outer ring retainer is arranged, and this retainer is the monolithic entities retainer, and its both sides are evenly equipped with axial pocket hole, and cross-shaped layout between the pocket hole of both sides.In each pocket hole roller is arranged all, this roller is dolioform spherical roller; The internal surface of outer ring and be sphere with the corresponding inner ring raceway of roller.Be characterized in having in the middle of the outer side surface of retainer circumferential boss, the outer surface of this circumferential boss be sphere and and inner surface between be and be slidingly matched.
Wherein, oilhole is arranged on the outer ring, this oilhole is corresponding with the circumferential boss on the retainer.
Raceway both sides at inner ring all are useful on the rib that blocks roller.
Take such scheme, have the following advantages:
Because the utility model is processed with circumferential boss in the middle of the outer side surface of its retainer, the outer surface of this circumferential boss be sphere and and inner surface between be and be slidingly matched, become tradition and be the outer ring guiding by inner ring guiding retainer, avoided direct contact the between retainer and inner ring, retainer and roller have been alleviated by the vibration in the external world, vibration and the acceleration that impulsive load is brought, make retainer highly stable between Internal and external cycle, thereby make retainer and roller not fragile, prolong the working life of bearing.
Owing to be processed with oilhole on the outer ring,, can guarantee that bearing is in good lubricating status all the time again by frequent interpolation lubricant oil.Like this, also can prolong the working life of bearing.
Description of drawings
Accompanying drawing is a vibrating machine of the present utility model selfaligning roller bearing structural representation.
Embodiment
As shown in drawings, vibrating machine of the present utility model contains inner ring 1 and outer ring 6 with selfaligning roller bearing, and 6 of inner ring 1 and outer rings are provided with retainer 3, and the raceway both sides of inner ring 1 all are processed with the rib that is used to block roller 2.
Said retainer 3 is the monolithic entities retainer, and its both sides are evenly equipped with axial pocket hole, and cross-shaped layout between the pocket hole of both sides.In each pocket hole roller 2 is installed all, this roller is dolioform spherical roller.The internal surface of outer ring 6 and be sphere with roller 2 corresponding inner ring 1 raceways.Be processed with circumferential boss 4 in the middle of the outer side surface of retainer 3, the outer round surface of this circumferential boss be sphere and and outer ring 6 internal surfaces between be and be slidingly matched, thereby guide retainer 3 motions by outer ring 6, avoided retainer 3 directly with vibrate bigger inner ring 1 and contact, so, alleviate roller 2, retainer 3 because vibration and the acceleration that extraneous vibration and impulsive load are brought reduced friction and impact between roller 2 and two raceways, prolonged the working life of bearing.
For ease of adding lubricant oil, on the axial neutral position of outer ring 6, be processed with oilhole 5, this oilhole is corresponding with the circumferential boss 4 on the retainer 3.
Claims (3)
1. the vibrating machine selfaligning roller bearing comprises inner ring (1) and outer ring (6), between inner ring (1) and outer ring (6) retainer (3) is arranged, and this retainer is the monolithic entities retainer, and its both sides are evenly equipped with axial pocket hole, and cross-shaped layout between the pocket hole of both sides; Roller (2) is all arranged in each pocket hole, and this roller is dolioform spherical roller; The internal surface of outer ring (6) and be sphere with corresponding inner ring (1) raceway of roller (2); It is characterized in that having in the middle of the outer side surface of retainer (3) circumferential boss (4), the outer surface of this circumferential boss be sphere and and outer ring (6) internal surface between be and be slidingly matched.
2. vibrating machine selfaligning roller bearing according to claim 1 is characterized in that on the outer ring (6) oilhole being arranged, and this oilhole is corresponding with the circumferential boss (4) on the retainer (3).
3. vibrating machine selfaligning roller bearing according to claim 1 and 2 is characterized in that the raceway both sides of inner ring (1) all are useful on the rib that blocks roller (2).
