摘要： A yaw drive method of a wind power generation apparatus, in which a second gear engaged with a first gear attached to one of tower or a wind power generation unit supported to the upper end of the tower so as to be capable of yawing and supported to a tower or to the upper end of the tower is rotated by a drive motor attached to the other of the tower or the wind power generation unit for yawing the wind power generation unit. A drive energy, which is supplied to the drive motor for a predetermined time from when the supply of the drive energy to the drive motor begins to start, is made to be smaller than the drive energy supplied to the drive motor in a common yawing.

摘要： When the load acting on a fluid motor (25) increases, a changeover valve (61) starts to be changed over toward a low-speed position L, but at this time an additional pilot fluid whose pressure is determined by the amount of fluid flowing into or out of a second passage (68) through first and second notches functions as a pressure regulator for a spool (65), and lowers the pressure within the second passage (68) without lowering the pressure within a high pressure-side main circuit (28), thereby tilting a swash plate (26) from a position of high-speed rotation to a position of low-speed rotation.

摘要： A speed reducer and a yaw drive apparatus for a wind power generation apparatus, where the speed reducer has high efficiency and a short axial length, and suitable for the yaw drive apparatus. The speed reducer has three stages for speed reduction. The total reduction gear ratio of a first stage speed reducing portion 10 and a second speed reducing portion 20 is set to 1/6 to 1/60, and a third stage speed reducing portion 30 is constructed from an eccentric oscillating-type speed reduction mechanism having an internal gear member 32, external gears 34, crankshafts 35, and a carrier 37. The reduction gear ratio of the eccentric oscillating-type speed reduction mechanism is set to 1/50 to 1/140, and the total reduction gear ratio of the speed reducer is set to 1/1000 to 1/3000. A yaw drive method and the yaw drive apparatus can reduce noise, and the yaw drive apparatus is inexpensive and reduced in size.

摘要： Axial positions of two driven external gears 66 making up each of a plurality of paired-gear groups 67 with respect to an input shaft 62 are made identical, and a different paired-gear group 67 is arranged by being offset in the axial direction of the input shaft 62. Therefore, only two driven external gears 66 making up the paired-gear group 67 are present at an identical axial position of the input shaft 62. Consequently, even if the diameters of these driven external gears 66 are made large up to the very limit, these driven external gears 66 do not interfere with each other. Accordingly, it is possible to readily enlarge the reduction ratio based on the driving and driven external gears 65 and 66.
摘要翻译：构成多个成对齿轮组67中的每一个的两个从动外齿轮66相对于输入轴62的轴向位置相同，并且不同的一对齿轮组67沿轴向方向偏移输入轴62.因此，只有两个构成成对齿轮组67的从动外齿轮66存在于输入轴62的相同的轴向位置。因此，即使这些从动外齿轮66的直径大到这些被驱动的外部齿轮66不是相互干扰的极限。因此，可以容易地根据驱动和驱动的外齿轮65和66放大减速比。
