Abstract

The invention relates to a holder for a cylindrical roller bearing and a cylindrical roller bearing. Specifically, the holder is equipped with two side rings opposite in the axial direction, and a plurality of beams connecting the two side rings. A pocket is disposed every two adjacent beams, each of the beams is equipped with at least one accommodating part, and the inside of the accommodating part has a dismountable insert, which protrudes into the pockets of both sides. According to the invention, the inserts and the grooves can realize detachable connection, and the extension length of the inserts into the pockets can be well controlled.

Description

technical field [0001] The invention relates to a bearing, in particular to a cage for a cylindrical roller bearing and the cylindrical roller bearing. Background technique [0002] In the prior art, a cylindrical roller bearing includes an inner ring, an outer ring surrounding the inner ring, a cage located between the inner ring and the outer ring, and cylindrical rollers located in the cage and spaced apart from each other. Among them, refer to figure 1 The cage 10 includes two axially opposite side rings 11 , a plurality of beams 12 connecting opposite sides of the rings 11 on both sides, and a pocket 13 is formed between two adjacent beams 12 . Pockets 13 are used for installing cylindrical rollers, and adjacent cylindrical rollers are separated by beams 12 . Two smaller protrusions 14 are arranged on the end face of the beam 12 opposite to the inner ring, the two protrusions 14 are spaced apart from each other in the axial direction, and the protrusions 14 slightly e...
