Abstract: A reinforcement object is reinforced without being carried out from a wind turbine power generation facility. A method of remodeling a wind turbine power generation facility includes: a carry-in step of carrying a reinforcement member into a hub through an opening portion which has a smaller dimension than a reinforcement object inside the wind turbine power generation facility and which brings into communication inside of the hub and outside of a front side of the wind turbine power generation facility, the reinforcement member having a smaller dimension than the opening portion; and a reinforcement step of processing the reinforcement object inside the hub, and reinforcing the reinforcement object by using the reinforcement member carried into the hub.

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.

Abstract: A starting method is provided for a rotating machine which includes a main shaft, a main bearing rotatably supporting the main shaft and a main bearing lubricant pump circulating lubricant through the main bearing. The starting method includes steps of: rotating the main shaft to raise a temperature of the main bearing in a state in which the main bearing lubricant pump is not operated; and operating the main bearing lubricant pump to start supplying the lubricant to the main bearing after the step of raising the temperature of the main bearing.

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.

Abstract: A planetary gear train is provided with a planetary gear and a planetary pin inserted into the planetary gear. The planetary gear includes: a gear member having teeth on the outer face and a through hole; an intermediate housing inserted into the through hole and having an insert hole into which the planetary pin is inserted; and a plurality of sliding bearing members jointed onto the insert hole of the intermediate housing. The plurality of sliding bearing members form a sliding bearing which sustains the planetary pin and the planetary gear to be rotatable with each other.

Abstract: A lubricant heating mechanism is provided with a tank accumulating therein lubricant; a lubricant pump; a heater provided in the tank to heat the lubricant; and a baffle plate at least partially covering the heater. The tank is provided with a suction port drawing out the lubricant from the tank to the lubricant pump. The baffle plate is provided to convect the heated lubricant toward the suction port.

Abstract: A wind turbine generator is provided in which damage to a rolling element due to running out of lubricant oil in a main bearing (10) can be reliably prevented even if a wind turbine idles during a power failure. In a wind turbine generator in which the main bearing (10) of a laterally disposed main shaft (6) has an oil supply port (14) and a drain port (15) for lubricant oil, and in which the lubricant oil supplied from an oil pump flows through the oil supply port (14) into the main bearing (10) and flows out through the drain port (15) to circulate, the drain port (15) is disposed above the center of a lower rolling element disposed in the main bearing (10).
