Embodiment Construction

[0023] Such as figure 2 As described above, a spherical roller bearing based on a split cage in the present invention includes a bearing outer ring 1 and a bearing inner ring 2 arranged concentrically, and a bearing outer ring 1 and the bearing inner ring 2 are provided with Split cage.

[0024] Such as Figure 2 to Figure 8 As shown, the split cage is composed of the first cage 6 and the second cage 16; the first cage includes a ring-shaped first cage body 61, and the A plurality of first limiting blocks 62 on one side of the first cage body 61, a first pocket 63 is formed between two adjacent first limiting blocks 62, and the first pocket 63 Rolling body 4 is arranged inside.

[0025] Such as Figure 7 , Figure 8 As shown, the second cage includes a ring-shaped second cage body 161 that is the same size as the first cage body 61, and is uniformly arranged on one side of the second cage body 161 in a ring shape. A plurality of second limiting blocks 162 on the top, a ...

Abstract

The invention discloses a self-aligning roller bearing based on a split holder. The split holder is arranged between a bearing outer ring and a bearing inner ring and is combined by a first holder anda second holder; the first holder comprises a ring-shaped first holder body and a plurality of first limiting blocks which are annularly distributed on one side face of the first holder uniformly, and a first pocket hole is formed between two adjacent first limiting blocks; the second holder comprises a ring-shaped second holder body same in size as the first holder body and a plurality of secondlimiting blocks which are annularly distributed on one side face of the second holder uniformly, and a second pocket hole is formed between adjacent two second limiting blocks. The load subjected tothe self-aligning roller bearing is improved, the strength of the holder is improved, and the guiding effect is also improved.

Description

technical field [0001] The invention relates to the technical field of new type bearing product development, and more specifically relates to a cage of a self-aligning roller bearing that improves impact load. Background technique [0002] At present, the cage of the domestic conventional 241 series spherical roller bearing is integrated (for medium and large), and the design of the cage size is limited by the size of the outer ring. Such as figure 1 As shown, a conventional 241 series spherical roller bearing includes an outer ring 100 , an inner ring 200 , an integral cage 600 sandwiched between the outer ring and the inner ring, and rolling elements 400 installed on the integral cage 600 . [0003] Due to the special size of the 241 series, in order to meet the installation requirements, it is necessary to reduce the outer diameter of the cage from the theoretical design size; increase the outer and inner diameter of the outer ring; reduce the length of the rolling eleme...
