CUSCINETTO LINEARE CON GUIDA A C A PISTE CONTRAPPOSTE DI CUI UNA PISTA CON SUPERFICIE A PORZIONE DI CILINDRO

摘要

PROBLEM TO BE SOLVED: To enable smooth movement of a slider even when the rail is not accurately parallelly arranged. SOLUTION: Two inner orbits 16, 20 opposed to each other are formed on a linear rail having a C-shaped section. A slider has at least three rollers 14a, 14b, 14c which are in alternative contact with the orbits. Outer peripheral surfaces of the rollers 14a, 14b, 14c have semi-circular arch form. The orbit 16 has a V-shaped section, and is composed of angularity formed two surfaces 16a, 16b. The orbit 20 has an arcuate section, having a larger radius than that of the semi-circular arch of the roller.
