Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus consistent with certain aspects of the invention, as detailed in the appended claims.

In order to solve the problems that the existing subdivision self-aligning roller bearing has many component parts, high processing cost, easy dislocation during installation, short service life and the like, the embodiment designs a new structure for replacement in the installation size space of the original bearing. Referring to fig. 1 and 2, the divided self-aligning roller bearing is composed of an upper bearing division body 1 and a lower bearing division body 2 which are butted up and down, wherein, referring to fig. 3, the upper bearing division body 1 includes: the inner ring upper part of a body 11, holder upper part of a body 12 and outer ring upper part of a body 13 that set gradually from inside to outside, lower part bearing components of a body 2 corresponds with upper part bearing components of a body 1 structure, include: the inner ring lower part 21, the holder lower part 22 and the outer ring lower part 23 are arranged from inside to outside in sequence, the inner ring upper part 11, the holder upper part 12 and the outer ring upper part 13 in the upper bearing part 1 are correspondingly butted with the inner ring lower part 21, the holder lower part 22 and the outer ring lower part 23 in the lower bearing part 2 one by one, and the butt joint port between the inner ring upper part 11 and the inner ring lower part 21, the butt joint port between the holder upper part 12 and the holder lower part 22 and the butt joint port between the outer ring upper part 13 and the outer ring lower part 23 are all V-shaped ports.
