Traction type transmission
First Claim
1. A traction type transmission characterized in that a planetary roller mechanism is constituted by a sun roller, a plurality of planetary rollers disposed equidistantly around said sun rollers and exterior rings disposed outside said plurality of planetary rollers;
- said sun roller is coupled to a high speed shaft while either said exterior rings or planetary shafts supporting said planetary rollers are connected to a low speed shaft;
each of said planetary rollers is divided concentrically into a roller portion on the side of said planetary shaft and a ring portion on the outer peripheral side with a gap between them;
said ring portion is pushed strongly to the outer periphery of said sun roller in the presence of an oil; and
two right and left slope surfaces of the inner periphery of said exterior ring is strongly pressed to both shoulder portions of the outer periphery of said ring portion in the presence of the oil, respectively.

Abstract
A traction type transmission characterized in that a planetary roller mechanism is constituted by a sun roller, a plurality of planetary rollers disposed equidistantly around the sun roller and an exterior ring disposed outside the planetary rollers, the sun roller is connected to a high speed shaft while either the exterior ring or the planetary shafts of the planetary rollers are connected to a low speed shaft through a rotary member; the planetary rollers are strongly pressed to the outer periphery of the sun roller in the presence of an oil and two slope surfaces of the inner periphery of the exterior ring are strongly pressed to both shoulder portions of the outer periphery of these planetary rollers in the presence of an oil, respectively.
