PURPOSE:To perform smooth lubrication to supporting shaft of a taper cone by forming a space, which is open to a longitudinal direction of the supporting shaft, on the major dia. side of the taper cone and boring an oil passage for lubrication between the space and the supporting shaft. CONSTITUTION:On the end face on the major dia. side of a taper cone 7, a space (B) for retaining lubricating oil which is open to a longitudinal direction of a supporting shaft 6 is provided, and an oil passage 7b for lubrication from the space (B) is bored in a gap between the supporting shaft 6 provided with a needle bearing 15 and the taper cone 7. For this non-stage change gear, the attitude of a case 1 is set so that a main shaft 3 can be approximately horizontal, lubricating oil is reserved inside the case 1 to the extent that the main shaft 3 is not subsided, and lubricating oil in the space (B) is supplied to the supporting shaft 6 via the oil passage 7b due to centrifugal force involved in the rotation of a carrier 5 during transmission. |
