Claims

[Scope of utility model registration request]

(1) A sun roller, an outer ring that surrounds the sun roller in its axial direction and is disposed on a concentric axis with the sun roller, and is fitted into an annular space between the sun roller and the outer ring and makes rolling contact with the outer peripheral surface of the sun roller. A planetary roller that
A carrier that is connected to a drive shaft disposed on a concentric axis with the sun roller and a roller support that makes sliding contact with the outer peripheral surface of the planetary roller, and that transmits rotational drive of the driveshaft to the planetary roller via the roller support. The traction mechanism is arranged on a two-stage concentric shaft, and the first stage sun roller and the last stage carrier are connected, and an axial oil supply path is provided at the radial center of the drive shaft of each stage sun roller and carrier. An oil supply pipe with an oil injection port formed at the tip is inserted into the oil supply path of the first-stage carrier with the oil injection port facing the final stage side, and the driving force generated by the rotational drive of the first-stage carrier is terminated. In a planetary roller type transmission in which oil is transmitted through the sun rollers of the first stage and is supplied into the oil supply path of the first stage, the oil is injected from the oil injection port into the oil supply path by the rotational drive of the first stage. A planetary d-ra type transmission, characterized in that the oil supply pipe extends into a connecting portion between a sun roller in the first stage and a carrier in the final stage, and oil is injected into an oil supply path of the connecting portion.

(2) Oil discharge port in the middle of the oil supply pipe
The planetary roller type transmission according to claim 1, which is a registered utility model, and is characterized in that the oil is discharged from the oil discharge port into the oil supply path of the first stage sun roller.
