Description
Technical Field
The invention relates to the technical field of bearings, in particular to a large-aligning-angle wide-outer-ring aligning roller bearing.
Background
Currently, self-aligning roller bearings (also called spherical roller bearings) are mainly used in mechanical occasions where shaft misalignment exists, and the self-aligning performance of the self-aligning roller bearings allows a transmission shaft to slightly swing. The aligning angle of a conventional constant-width bearing is generally in the range of 0 to 2 degrees. When a larger aligning angle is needed, the width of the outer ring is increased to form a wide outer ring and narrow inner ring structure, and the aligning angle can reach more than 3 degrees to the maximum.
For example, patent CN 103790959A (a self-aligning roller bearing) discloses a wide-outer-ring self-aligning roller bearing with a self-aligning angle of 3 ° 42', and nylon material is used for the two retainers. The bearing is applied to a cement mixer speed reducer. Patent No. CN 101586621A (wide outer ring spherical roller bearing) discloses a wide outer ring self-aligning roller bearing of a strut welded retainer. The bearing is applied to chemical fiber equipment. Neither of the above patents disclose details of the assembly of the bearing. Actually, a big problem faced by the wide outer ring self-aligning roller bearing is that the conventional retainer of the bearing cannot be assembled inside the bearing. As the width of the outer race increases, its spherical raceway nadir (commonly referred to as the E-value) decreases, with the greater the increase in width, the smaller the E-value. Whereas the outer diameter of the cage of a normal design exceeds this value, resulting in the cage not going inside the bearing. From the above two patent diagrams, it can be seen that the outer diameter of the retainer is significantly higher than the E value of the outer ring, and the patent technology only proposes a solution that the outer ring can increase the aligning angle, but does not solve or ignore the bearing assembly problem.
In contrast, patent CN 109322912A (an easy-to-maintain split type anti-impact large-centering-angle self-aligning roller bearing) and patent CN 2619084Y (double-half-outer-ring spherical roller bearing) both adopt split outer ring structures, and at this time, the problem of small E value of the outer ring does not need to be considered, and the two half outer rings can be wrapped by the retainers from both sides to complete assembly. However, the bearing outer ring is split and then assembled by the technology, so that the manufacturing difficulty is increased, the integral spherical raceway of the outer ring is damaged, the contact stress of the raceway is the basis of the theoretical service life of the bearing (GB 6391), and the integrity of the bearing raceway is forbidden to be damaged in the bearing manufacturing process under the general condition.
In summary, the wide outer ring self-aligning roller bearing has defects in the prior art, the increase of the self-aligning angle and the assembly of the retainer have contradictions, and in order to solve the assembly problem, the outer ring is split to destroy the integrity of the raceway.

As shown in fig. 2, wherein a corresponds to a conventional bearing and B corresponds to a bearing defined by the present invention; it can be seen that after the conventional bearing outer ring is widened, the outer diameter of the retainer is obviously higher than the minimum diameter E value of the outer ring raceway, so that the retainer cannot be assembled into the bearing. The outer diameters of the two retainers and the inner spacer in the bearing are smaller than the E value, so that the assembly of the retainers can be completed on the premise of not damaging the outer ring, and the rear aligning angle of the outer ring is widenedαThe self-aligning angle of the embodiment of the invention can reach more than 5 degrees.
