Title (EN) IMPROVED ROLLER BEARING
(FR) PALIER A ROULEAUX AMELIORE
Abstract: front page image
(EN)Conventional recirculating roller bearings often do not travel precisely perpendicular to the axis of the race. This roller skewing raises the level of friction in the system. The present invention provides an improved recirculating roller bearing (10) and a roller element (12) therefor in which the end members (18) of the rollers (12) have an axial bore (20) within a portion of the cylindrical end member (18). The axial bore extends between 30% and 50% of the length, and between 20% and 30% of the diameter of the cylindrical end member (18). This configuration effectively neutralizes the effects of roller skewing by reducing the amount of corrective force needed to realign a roller into a straight rolling trajectory.
(FR)Souvent les paliers a rouleaux conventionnels ne se deplacent pas exactement perpendiculairement a l'axe de la course. Ce biais des rouleaux augmente le niveau de frottement dans le systeme. Cette realisation presente un palier a rouleaux ameliore (10) et un element de rouleau (12) dans lequel les organes d'extremite (18) des rouleaux (12) possedent un alesage axial (20) a l'interieur d'une partie de l'organe cylindrique d'extremite (18), L'alesage axial s'etend entre 30% et 50% de la longueur, et entre 20% et 30% du diametre de l'organe cylindrique d'extremite (18). Cette configuration neutralise efficacement les effets de biais des rouleaux en reduisant la force correction requise pour realigner un rouleau dans une trajectoire de roulements rectilignes.
