  • Planetary gear train with thrust collar used as thrust bearing of planetary gear and wind turbine generator incorporating the same
    Patent number: 8932177
    Abstract: A planetary gear train is provided with: a carrier; a planetary gear; a planetary pin inserted into an insert hole provided through the planetary gear and coupled to the carrier to rotatably support the planetary gear; a thrust collar attached to a surface opposed to the planetary gear of the carrier so as to surround the planetary pin; and a pin for coupling the thrust collar to the carrier. The thrust collar has a first surface opposed to the carrier and a second surface opposed to the planetary gear, and has a first pin hole provided on the first surface so as not to reach the second surface. The carrier has a second pin hole on a surface opposed to the planetary gear. The thrust collar is attached to the carrier by inserting the pin into the first pin hole of the thrust collar and into the second pin hole of the carrier.

  • Planetary gear train with oiling system for supplying lubricant oil to bearing of planetary gear and wind turbine generator incorporating the same
    Patent number: 8636615
    Abstract: A planetary gear train is provided with: a planetary gear; a planetary pin for supporting the planetary gear; a carrier for supporting the planetary pin; and a housing for accommodating at least a portion of the carrier, the planetary gear and the planetary pin. The planetary gear is rotatable with respect to the planetary pin by a bearing. An oiling flow path for supplying lubricant oil to the bearing is formed inside the carrier. The carrier receives the lubricant oil into the oiling flow path from an oiling member stationarily fixed to the housing. The inlet for receiving the lubricant oil into the oiling flow path of the carrier from the oiling member is positioned inside the housing.
