Embodiment Construction
[0008] like figure 1 As shown, a self-aligning tapered roller bearing with double outer rings includes an outer ring set, an inner ring and tapered rollers; the outer ring set includes a first outer ring 01 and a second outer ring 11 that are concentrically socketed. Wherein, the second outer ring 11 is located outside, its outer wall surface is a cylinder, and its inner wall surface is a spherical surface; the first outer ring 01 is located inside, and its outer wall surface is spherical to match the inner wall of the second outer ring 11; the first outer ring The inner wall of 01 is used as a raceway for tapered rollers. In addition, in a preferred manner, the bearing is a double-row tapered roller bearing, and the two rows of tapered rollers are arranged in a figure-eight shape on the cross-section of the axis intersection point in the bearing, and each row of tapered roller bearings is correspondingly provided with half of the first outer ring on the side , half of the se...

The invention discloses a dual-outer ring self-aligning conical roller bearing which comprises an outer ring set, an inner ring and a conical roller; the outer ring set comprises a first outer ring (01) and a second outer ring (11) nested with each other concentrically; the second outer ring (11) is arranged externally and the outer wall surface thereof is a cylindrical surface, and the inner wall surface is a spherical surface; the first outer ring (01) is arranged internally, the outer wall surface of the first outer ring is a spherical surface matched with the inner wall of the second outer ring (11); and the inner wall of the first outer ring (01) is used as the roller way for the conical roller. The invention realize the bearing automatic alignment and the rolling function of the roller body, effectively solves the deformation caused by bearing mounting error and greater bearing work temperature change, reduces the power loss due to sliding friction and improves the service life of the bearing.
Description
technical field [0001] The invention relates to a tapered roller bearing. Background technique [0002] The tapered roller bearings in the prior art do not have the self-aligning function, and cannot compensate the concentricity error caused by the installation and the deformation of the shaft, so the wear is serious, which affects the service life of the bearing. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned defects, and provide a tapered roller bearing that is easy to install and disassemble, and is equipped with a self-aligning unit, which can compensate the concentricity error caused by the installation and the deformation of the shaft. [0004] In order to achieve the above purpose, the present invention constructs a self-aligning tapered roller bearing with double outer rings, which includes an outer ring set, an inner ring and tapered rollers. The outer ring set includes a first outer ring 01 and a second out...
