Embodiment Construction

[0048] figure 1 Shown is a bearing 10 having two bearing rings, an inner ring 12 and an outer ring 14 delimiting an annular space 16 in which rolling bodies 18 are housed, in this case Cylindrical rollers. The rollers 18 are adapted to roll on annular raceways 20, 22, which in this case are cylindrical raceways, and which are formed on the two bearing rings 12, 14, thereby allowing the Relative rotation between the rings 12 , 14 about the axis of rotation 100 of the bearing 10 . The rollers 18 are arranged in the annular volume 16 between the two bearing rings 12 , 14 without intervening guide cages, thus maximizing the number of rollers 18 . The bearing rings 12 , 14 do not have guide collars opposite the end faces 24 of the rollers, which allows maximizing the axial dimension of the rollers 18 .

[0049] The two bearing rings 12 , 14 are framed by two identical guide flanges 26 . Each of the guide flanges 26 is located at one axial end of the bearing 10 and is crimped to...

Abstract

A bearing (10) comprises two bearing collars (12, 14); a rolling body (18), which is stored in an annular space (16) between two bearing collars (12,14); and at least one annular flange (26), which isabutted to the first one of two bearing collars (12, 14) at the first axial end of the first one of two bearing collars (12, 14) in a crimping mode. The first flange comprises an annular edge (42), which stays on the edge of a crimping abutting groove (48) and has a slope (44); and a folded edge formed on the first of two bearing collars (12, 14) is folded on the slope.

Description

technical field [0001] The present invention relates to bearings, in particular to bearings equipped with a deflector allowing relative axial retention between an inner ring and an outer ring, and a method of manufacturing the bearing. [0002] More specifically, the invention relates to such a bearing intended to constitute a loom roller of a textile machine. Background technique [0003] In a known manner, a mechanical bearing comprises an inner ring and an outer ring, between which a bearing space is formed in which rolling bodies are arranged. For certain applications where axial space is highly restricted, the bearings are not fitted with collars to axially retain the rolling elements and center the bearing rings relative to each other via the rolling elements. [0004] In these cases it is known to use deflector plates to guide the outer ring relative to the inner ring and create a sealed barrier between the bearing space and the outside, preventing the intrusion of c...
