Abstract
The invention discloses a spherical roller bearing with high self-aligning performance. The spherical roller bearing comprises an inner ring and an outer ring, wherein a roller path between the inner ring and the outer ring is partitioned into an inner-layer roller path and an outer-layer roller path by a middle spacing ring arranged between the inner ring and the outer ring, the double layers of roller paths are internally provided with rollers; the upper and bottom surfaces of the double layers of roller paths partitioned by the middle spacing ring are arc surfaces with fixed radians; the rollers are spherical rollers and are symmetrically arranged in the double layers of roller paths in two columns; the positions of the rollers are retained by a retainer; the two columns of rollers are respectively positioned by a boss formed between the two columns of rollers and the retaining surfaces on the two sides. The spherical roller bearing adopts the arrangement of the double layers of roller paths, the performance of the self-aligning roller bearing is greatly improved, the self-aligning angle is changed to be 2-5 degree, the bearing capability of the bearing is approximately increased by 60%; meanwhile, shallow grooves are formed in the boss and the retaining surfaces to form oil films, and thus the friction is alleviated and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to the bearing that mechanical field is used, specifically a kind of high aligning performance spheric roller bearing.
Background technique
Selfaligning roller bearing has two row rollers, mainly bears radial load, also can bear the thrust load of either direction simultaneously.Such bearing outer ring ball track is spheric, therefore its aligning performance is good, energy compensating coaxial degree error, have two row symmetric form spherical rollers, there is a shared spherical raceway outer ring simultaneously, inner ring have two with the tilt raceway of an angle of bearing axis, there is good aligning performance, when the stressed bending of axle or installation decentraction, bearing still can normally use, and aligning is different and different with bearing size series, and general allowed aligning angle is 1 ~ 2.5 degree.But because the aligning angle of its permission is less, and its bearing capacity also has certain restriction, cause its life-span when some needs the occasion of large bearing capacity and large aligning angle to use very low.
Summary of the invention
For solving the problem that existing selfaligning bearing aligning angle is little and bearing capacity is poor, the invention provides a kind of high aligning performance spheric roller bearing, the aligning angle of this bearing is 2 ~ 5 degree, its bearing capacity existing selfaligning bearing of comparing has improved 60% left and right, has greatly improved the performance of selfaligning bearing.
The present invention solves the problems of the technologies described above the technological scheme of employing to be: a kind of high aligning performance spheric roller bearing, comprise inner ring and outer ring, the centre circle being arranged between inner ring and outer ring is divided into inside and outside double-deck raceway by the raceway between inner ring and outer ring, in double-deck raceway, spherical roller is all set, the upper and lower surface of the described two-layer raceway being separated into by centre circle is the spherical that shape is consistent, described roller is spherical roller, and being divided into two row is symmetricly set in double-deck raceway, and keep its position by retainer, two row rollers are located by the boss between two row rollers and the maintenance face of both sides respectively.
Described outer ring is 2 ~ 5 ° with respect to the aligning angle of inner ring.
The surface of described boss and maintenance face is evenly equipped with shallow slot, and the bottom of shallow slot is all communicated with so that lubricant oil can enter shallow slot with the lower surface of double-deck raceway.
The position that described boss contacts with double-deck raceway lower surface with maintenance face is provided with eliminate roller point stresses and stores the groove of lubricant oil.
In the present invention, owing to playing the boss of positioning action and keeping the surface of face to be distributed with shallow slot, when roller rolls, can push the lubricant oil on double-deck raceway lower surface, thereby make lubricant oil be full of shallow slot then forms one deck oil film and reduces friction between roller and boss, maintenance face, wear prevention, the working life of having improved bearing.
Beneficial effect: the present invention adopts inside and outside double-deck raceway setting, and the performance of selfaligning roller bearing is greatly improved, aligning angle becomes 2 ~ 5 degree, and bearing capacity has improved 60% left and right; Meanwhile, thereby shallow slot is set on the surface of boss and maintenance face, form oil film, reduced friction, improved the working life of bearing.

Embodiment
As shown in the figure, a kind of high aligning performance spheric roller bearing, comprise inner ring 2 and outer ring 1, the centre circle 3 being arranged between inner ring 2 and outer ring 1 is divided into inside and outside double-deck raceway by the raceway between inner ring 2 and outer ring 1, in double-deck raceway, spherical roller 4 is all set, the upper and lower surface of the described two-layer raceway being separated into by centre circle 3 is the spherical that shape is consistent, described roller 4 is spherical roller, and being divided into two row is symmetricly set in double-deck raceway, and keep its position by retainer 5, two row rollers 4 are located by the maintenance face 7 of the boss 6 between two row rollers 4 and both sides respectively.
Described outer ring 1 is 2 ~ 5 ° with respect to the aligning angle of inner ring 2.
The surface of described boss 6 and maintenance face 7 is evenly equipped with shallow slot, thereby the bottom of shallow slot is all communicated with the lower surface of double-deck raceway, lubricant oil can enter shallow slot and form oil film.
The position that described boss 6 contacts with double-deck raceway lower surface with maintenance face 7 is provided with eliminate roller 4 point stresses and stores the groove 8 of lubricant oil.
