Antifriction bearing for a weaving loom with lubricating cavity and weaving loom pulling system comprising such a bearing

Abstract

The invention relates to an antifriction bearing (30) of the roller (34) type for a pulling system for a weaving loom, comprising: an inner race (32) and an outer race (36) lying one on each side of the rollers (34) defining two raceways (321) and (361), two end plates (40, 42) secured to the inner race (32) and positioned respectively and axially close to each flank (34a, 34b) of the rollers (34), each end plate (40, 42) lying radially (Y) beyond the raceways (321, 361), the end plates (40, 42) and the inner race (32) being intended to be mounted between two lateral flanges (24a, 24b). At least one end plate (40, 42) has a shape defining at least one cavity (41, 43) adjoining all or part of a flank (34a, 34b) of the rollers (34) and able to accept a lubricant. The inner race (32) has two lateral shoulders (32a, 32b) each one defining an axial bearing surface (32e, 32f) for each flange (24a, 24b), and the width (11) of the inner race (32) with its lateral shoulders (32a, 32b) is substantially equal to the distance (12) separating the outermost axial faces of the end plates (40, 42).
