Abstract

1341665 Friction gearing FUJIKOSHI KK 15 May 1972 [18 May 1971] 22671/72 Heading F2Q A planetary friction drive comprises a sun roller consisting of two wheels 16 freely slidable axially on a shaft 17, planetary rollers each consisting of a cylindrical surface 14, adapted to contact a fixed ring 12, and inclined end portions 15 adapted to contact the surfaces of sun roller wheels 16, the planetary rollers being mounted in a carrier secured to a shaft 23, and a torque responsive cam mechanism for pressing the sun rollers axially into engagement with the planetary rollers. The cam mechanism comprises balls 29, Fig. 4, located between cam plates disposed between the ends of the wheels 16 and spring-pressed discs 27.
