Claims

[Claims for Utility Model Registration] (1) An axially long first planetary gear and an axially short second planetary gear that mesh with each other are held by a common planetary carrier, and both planetary gears are separated into separate sun gears and ring gears. In a planetary gear transmission having a planetary gear train in mesh with each other, a sleeve cylinder shaft that pivotally supports the second planetary gear is extended in the axial direction so as to face a sun gear disposed radially inward of the planetary carrier. A pin-shaped rivet connected to the planetary carrier is inserted inside the bearing sleeve in the radial direction, and a boss portion of the planetary carrier is provided that covers the outside of the sleeve cylinder shaft in the radial direction. A first lubricating oil hole is formed in the portion where the lubricating oil hole is formed, a first circumferential passage continuous in the circumferential direction is provided between the boss portion and the sleeve cylindrical shaft, and the first circumferential passage is continuous with the first lubricating oil hole. A second lubricating oil hole is formed in the sleeve cylindrical shaft continuous with the passage, and a second circumferential passage is provided continuous in the circumferential direction between the sleeve cylindrical shaft and the rivet, continuous with the second lubricating oil hole. A lubricating device for a planetary gear transmission, characterized in that a third lubricating oil hole is formed to communicate between the second circumferential passage and the bearing portion of the second planetary gear. (2) The lubricating device for a planetary gear transmission according to claim 1, wherein the planetary carrier is of a split type connected by a pin-shaped rivet.
