Abstract
The invention discloses a self-aligning roller bearing, which comprises a bearing outer ring, a bearing inner ring and a retainer, wherein the retainer is positioned between the bearing outer ring and the bearing inner ring, a plurality of rollers are arranged on the retainer in a rotating manner, two symmetrical adjusting grooves are formed in the bearing outer ring, adjusting bolts are connected in the adjusting grooves in a threaded manner, two retainers are arranged between the bearing outer ring and the bearing inner ring, a gap is formed between the two retainers, and an adjusting piece is arranged between the two retainers. According to the self-aligning roller bearing, the adjusting bolt rotates to downwards extrude the adjusting piece, so that the left side end and the right side end of the adjusting piece push the retainer, the roller can keep good clearance fit with the roller path, the clearance between the roller and the roller path is reduced, a good attaching effect can be kept between the roller and the roller path, and the use stability of the self-aligning roller bearing is better ensured.
Description
Technical Field
The invention relates to the technical field of bearings, in particular to a self-aligning roller bearing.
Background
The self-aligning roller bearing is provided with double rows of rollers, the outer ring is provided with a common spherical raceway, the inner ring is provided with two raceways and inclines to form an angle relative to the axis of the bearing, and the self-aligning roller bearing is suitable for occasions with installation errors or angle errors caused by shaft deflection; and in the process of the rotation of the roller pin, certain abrasion can be caused to the inner walls of the outer ring and the inner ring of the bearing, so that the roller and the roller path are easily loosened to influence the use stability of the bearing.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a self-aligning roller bearing.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides an aligning roller bearing, includes bearing inner race, bearing inner race and holder, the holder is located between bearing inner race and the bearing inner race, it has a plurality of rollers to rotate on the holder, set up two adjustment tanks of symmetry on the bearing inner race, adjustment tank female connection has adjusting bolt, holder between bearing inner race and the bearing inner race is two, and has the clearance between two holders, two the regulating part has been placed between the holder.
Preferably, the adjusting piece is of a rhombic design in side section, is of an annular design, and is made of an integrally formed metal sheet.
Preferably, the bearing outer ring and the bearing inner ring are provided with raceways corresponding to the rollers.
Preferably, the adjusting bolt is inserted into a position between the two holders and is located on the adjusting member.
Preferably, one end of each of the two cages close to each other slides between the bearing outer ring and the bearing inner ring.
Compared with the prior art, the invention has the following advantages: the adjusting bolt rotates to downwards extrude the adjusting piece, so that the left side end and the right side end of the adjusting piece push the retainer, the roller can keep good clearance fit with the raceway, the clearance between the roller and the raceway is reduced, a good attaching effect can be kept between the roller and the raceway, and the use stability of the self-aligning roller bearing is better ensured; the retainer of two rows of rollers is divided into two parts, so that the matching effect of the rollers, the bearing outer ring and the bearing inner ring is more convenient to adjust, and meanwhile, the adjusting bolt is positioned in the adjusting groove, so that the installation of the bearing outer ring is not influenced.
Drawings
Fig. 1 is a cross-sectional view of a self-aligning roller bearing according to the present invention;
fig. 2 is a side view of a self-aligning roller bearing according to the present invention.
In the figure: 1 bearing outer ring, 2 bearing inner ring, 3 retainer, 4 rollers, 5 adjusting grooves, 6 adjusting bolts and 7 adjusting parts.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-2, a self-aligning roller bearing, including bearing inner race 1, bearing inner race 2 and holder 3, holder 3 is located between bearing inner race 1 and the bearing inner race 2, it has a plurality of rollers 4 to rotate on the holder 3, set up two adjustment tank 5 of symmetry on the bearing inner race 1, 5 threaded connection of adjustment tank has adjusting bolt 6, holder 3 between bearing inner race 1 and the bearing inner race 2 is two, and there is the clearance between two holders 3, adjusting part 7 has been placed between two holders 3, through dividing into two with integrative holder 3 of tradition, make the position of roller 4 more be convenient for adjust, thereby make cooperation bearing inner race 1 and bearing inner race 2 that roller 4 can be better, guarantee its good laminating nature, make the bearing use more stable.
Furthermore, the side section of the adjusting piece 7 is designed in a diamond shape, the adjusting piece 7 is designed in an annular shape, the adjusting piece 7 is made of an integrally formed metal sheet, and the adjusting piece 7 has a certain elastic deformation function and is convenient for adjusting the retainer 3 and the roller 4. The bearing outer ring 1 and the bearing inner ring 2 are provided with raceways corresponding to the rollers 4. The adjusting bolt 6 penetrates into a position between the two holding frames 3 and is positioned on the adjusting piece 7, and the adjusting bolt 6 is used for extruding the adjusting piece 7 to deform the adjusting piece 7. One end of each of the two retainers 3, which is close to each other, slides between the bearing outer ring 1 and the bearing inner ring 2, so that the left end and the right end of the adjusting piece 7 can push the retainers 3 to perform certain adjustment.
When the roller 4 is loose in use, the adjusting bolt 6 rotates to extrude the adjusting piece 7 downwards, so that the left side end and the right side end of the adjusting piece 7 push the retainer 3, the roller 4 can keep good clearance fit with the roller path, the clearance between the roller 4 and the roller path is reduced, and the use stability of the self-aligning roller bearing is better ensured.
