Abstract

PURPOSE: To reduce the stress concentration in a captioned device by using at least one roller made of elastic materials among sun, planet, and inner rollers, and giving a crowing deformation to a thin cylinder part of the roller in contact with other rollers when the roller is pushed on both sides.
CONSTITUTION: The rotational power of an input shaft 1 is transmitted to an inner roller 9 or an output shaft 3 via a sun roller 2 and a planet roller 7. For example, when the inner roller 9 is made of elastic materials, the inner roller 9 consists of a thick cylinder part 9b and a thin disk part 9c on both sides, and a thin cylinder part 9a'. The backside 9e' of the thin cylinder part 9a' is provided with a smooth circular-arc-shaped vertical section with a radius of curvature R and the finish of grinding. Consequently, even if pushing forces are given to the inner roller 9' from on both sides, the stress concentration is not given to the backside 9e', and the roller 9' is prevented from damages. The finish of grinding, furthermore, serves to reduce the stress concentration.
