の潤滑構造。 In a two-stage planetary gear reduction device that decelerates and transmits the rotational force of a hydraulic motor to a rotated body, the planet located at the upper part of the second stage planetary gear rotatably supported by a second carrier fixed to a casing. A greasing hole that communicates with the bearing of the gear is bored in the support shaft, and an oil reservoir opening in the outer circumferential direction is formed in the supporting side wall of the carrier located on the opening side of the greasing hole. The lubricating oil splashed and dripped on the tooth surface by the rotation of the internal gear drilled in the rotating body is collected in the oil reservoir and then supplied to the bearing through the greasing hole. Characteristic lubrication structure of planetary gear reduction gear.
