Split type cylindrical roller bearing

Abstract

The invention discloses a split type cylindrical roller bearing, which has a double-row structure. Each row comprises an outer ring, a row of cylindrical rollers (04), a set of retainer and an inner ring, wherein the outer ring is formed by abutting two semi-outer rings (51), and the inner ring is formed by abutting two semi-inner rings (52). Flanges are arranged at two ends of the outer ring of each row towards the axle center direction and are used for limiting the axial position of the rollers. The two rows of the inner rings prop against each other, the two rows of the outer rings are separated via an outer annular space ring, and the outer space ring is formed by abutting two semi-outer space rings (53). A retaining ring is arranged at two ends of the inner ring of each row and formed by abutting two semi-retaining rings, the retainer is formed by buckling a retainer seat (06) and a retainer cover (16), and both the retainer seat (06) and the retainer cover (16) are formed by abutting two semi-circular frame bodies. The bearing is convenient to mount and dismount, is convenient and fast to mount, maintain and replace parts, and is adaptable to a main shaft with a shaft journal which is small in middle and large at two ends.

Description

technical field [0001] The present invention relates to a bearing, and more particularly, to a cylindrical roller bearing. Background technique [0002] In the prior art, for the assembly of the long shaft of the integral bearing, the entire shaft needs to be dismantled or padded to be assembled, especially when the adjacent parts are large, the installation is more inconvenient. For stepped shafts or multi-point supported shafts, for example, when the supporting part is not at the shaft end and the diameter of the supporting part is smaller than other parts, the integral bearing cannot be installed, resulting in a large disassembly and disassembly during maintenance, which is very inconvenient and not only prolongs the working cycle. It is long and labor intensive. Contents of the invention [0003] In view of the above problems, the present invention provides a bearing that is easy to assemble and disassemble, easy to maintain and can be assembled radially. It is suita...
