Abstract

Un cojinete de rodillos que incluye una cantidad de rodillos (6) provistos entre dos pistas (3, 5) y en contacto con las mismas, con lo cual los rodillosy las pistas presentan perfiles de sección longitudinal con sustancialmente el mismo radio de curvatura (R), siendo el radio de curvatura (R) mayor que ladistancia entre la pista exterior y el eje del cojinete, medida perpendicularmente contra la pista, con lo cual los rodillos (6) sonaxialmente móviles entre las pista sin obstrucciones debidas a limitaciones axiales en las pistas, de modo de permitir una desalineación relativa y unadesplazabilidad axial, de las pistas, las cuales están delimitadas solamente por el apretujamiento radial de los rodillos situados entre las pistas, siendola relación entre el radio de curvatura (R) del perfil de los rodillos y la longitud de los rodillos (Ia), inferior a 20 (R/Ia < 20).A roller bearing that includes a number of rollers (6) provided between and in contact with two tracks (3, 5), whereby the rollers and tracks have longitudinal section profiles with substantially the same radius of curvature (R ), the radius of curvature (R) being greater than the distance between the outer race and the bearing axis, measured perpendicularly against the race, with which the rollers (6) are axially mobile between the races without obstructions due to axial limitations in the tracks, in order to allow a relative misalignment and axial displacement, of the tracks, which are delimited only by the radial squeezing of the rollers located between the tracks, being the relationship between the radius of curvature (R) of the profile of the rollers and the length of the rollers (Ia), less than 20 (R / Ia <20).
