Abstract

Rodamiento lineal con un carro (1b, 1c, 46) guía, que está apoyado sobre bolas (3, 45) en un carril (2, 41) guía y puede desplazarse a lo largo de éste, estando sujetadas las bolas (3, 45) en las piezas (9, 9a, 9b, 47) guía, que están fijadas de manera desmontable al carro (1b, 1c, 46) guía y están dispuestas en los lados longitudinales del carril (2, 41) guía dotados de pistas (50), con lo que las piezas (9, 9a, 9b, 47) guía para cada circulación de bolas sin fin contienen una pista (51) para bolas (3, 45) de soporte, un canal (13, 23, 32, 48) de retorno para bolas (3, 45) de retorno y dos canales (19) de desvío que unen una con otra las zonas de las bolas (3, 45) de soporte y de retorno, y el canal (13, 23, 32, 48) de retorno integrado en la pieza (9, 9a, 9b, 47) guía presenta, en cada caso, una abertura (49) que se extiende a lo largo de toda su longitud, cuya medida en anchura es menor que el diámetro de las bolas (3, 45) empleadas, con lo que la abertura (49) también se extiende sobretoda la longitud del canal (19) de desvío correspondiente, con lo que los canales (19) de desvío y el canal (13, 23, 32, 48) de retorno presentan, en sus lados longitudinales opuestos a la abertura (49), un suelo (53) cerrado que interviene en el guiado de las bolas (3, 45) y, en la zona de desvío y retroceso para las bolas (3) en la pieza (9a, 9b) guía, está formada la abertura por un estrechamiento (26) de los canales (23), la cual se encarga del guiado y de la retención de las bolas, con lo que en la zona de una pista (36) de soporte de la pieza (9a, 9b, 47) guía tiene lugar la retención, en cada caso, por medio de una brida (18a) de retención separada de un contorno (38) de retención, que está separada del contorno (38) de retención, caracterizado porque la separación es menor que el diámetro de las bolas (3).
