specific Embodiment 1

[0043] like figure 1 As shown, it includes an outer ring 1 , an inner ring 2 , a roller 3 , a spacer rod 4 and a tightening ring group, and the tightening ring group includes a first tightening ring 5 and a second tightening ring 6 .

[0044] Part of the structure of outer ring 1 is as follows figure 2 As shown, the outer ring 1 is annular as a whole, and both axial ends of the outer ring 1 have flanges 11 that are folded radially inward. Outer raceway 12. The structure of inner ring 2 is as follows image 3 As shown, the inner ring 2 has a cylindrical shape, and its outer peripheral surface constitutes an inner raceway 21 that fits with the rollers 3 .

[0045] like Figure 4 As shown, the roller 3 is cylindrical, and the two axial ends of the roller 3 are provided with matching ring grooves for the roller hooping ring. Specifically, each matching ring groove for the roller hooping ring includes two ring grooves, one for the first roller The sub-ring grooves 31 and the ...

specific Embodiment 2

[0053] The specific embodiment 2 of the cylindrical roller bearing provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, both ends of the cylindrical roller bearing in the axial direction are provided with a hoop ring group. In this embodiment, only the clamping ring group is arranged in the middle of the cylindrical roller bearing.

specific Embodiment 3

[0054] The specific embodiment 3 of the cylindrical roller bearing provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the tightening ring group is composed of two tightening rings. In this embodiment, the tightening ring group includes three tightening rings, and two adjacent ones of the three tightening rings are wound in opposite directions.

Abstract

The invention belongs to the field of bearings, and particularly relates to a cylindrical roller bearing and an assembling method of the cylindrical roller bearing, rollers are arranged between an inner ring and an outer ring of the cylindrical roller bearing, a cylindrical isolation rod with the diameter smaller than that of the rollers is arranged between every two adjacent rollers so as to separate the two adjacent rollers, the cylindrical roller bearing further comprises a hooping ring set, and the hooping ring set is arranged between the inner ring and the outer ring of the cylindrical roller bearing. The hooping ring set comprises a first hooping ring and a second hooping ring, roller hooping ring matching ring grooves are formed in the rollers, the first hooping ring sequentially bypasses the rollers and the isolation rods alternately inside and outside, the second hooping ring and the first hooping ring are arranged in the axial direction of the rollers in a spaced mode, and the second hooping ring sequentially bypasses the rollers and the isolation rods inside and outside in the direction opposite to the first hooping ring. The first hooping ring and the second hooping ring are arranged in the hooping ring set so that the rollers and the isolation rods can be clamped between the first hooping ring and the second hooping ring, the cross section size of the roller hooping ring matched ring groove in the axial direction of the rollers is equal to or larger than that of the hooping ring set, the hooping rings hoop the rollers on the inner ring, and sliding friction is effectively reduced or even avoided.

Description

technical field [0001] The invention belongs to the field of bearings, in particular to a cylindrical roller bearing and an assembling method of the cylindrical roller bearing. Background technique [0002] The rollers of cylindrical roller bearings are cylindrical and are in linear contact with the inner and outer rings of the bearing, so that the cylindrical roller bearing has excellent radial load carrying capacity and is a key component commonly used in machinery with slewing mechanisms. [0003] Regarding the specific structure of the cylindrical roller bearing, for example, a cylindrical roller bearing and an installation method thereof disclosed in the Chinese Invention Patent Application with the application publication number CN114135572A and the application publication date of March 04, 2022, the cylindrical roller bearing includes The outer ring, the inner ring, the cage and a plurality of rolling elements, the inner diameter surface of the outer ring is processed...
