Abstract

PURPOSE: To prevent the generation of the leak of lubricating oil, prevent the reduction of the rolling transmission power caused by the reduction of the traction coefficient and continue the stable power transmission by installing a heat radiation fin on the outer periphery of a housing into which a sun roller, planetary roller, and lubricating oil, etc. are accommodated.
CONSTITUTION: When power transmission is carried out from an input shaft 5 to an output shaft 13, the temperature of a housing 4 and the temperature of traction oil 15 rise. However, since heat radiation is carried out from a heat radiation fin 16, the remarkable rise of the temperature in the housing 4 and the temperature of the traction oil 15 are prevented. Accordingly, the remarkable increase of the air pressure in the housing 4 due to the remarkable rise of the temperature in the housing 4 is prevented, and the generation of oil leak caused by the increase of the air pressure is prevented. Further, the remarkable rise of the temperature of the traction oil 15 is prevented by the heat radiation of the heat radiation fin 16, and the remarkable reduction of the traction coefficient of the traction oil 12 is prevented.
