Abstract

A cage for a cylindrical roller bearing and a cylindrical roller bearing, wherein the cage includes two axially opposite side rings, a plurality of beams connecting the two side rings, and a gap between two adjacent beams The pocket hole is provided with at least one receiving part in the beam, and a detachable insert is provided in the receiving part, and the insert protrudes into the pocket holes on both sides. The insert and the groove of the present invention can realize detachable connection, and can better control the extension length of the insert into the pocket hole.

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...
