摘要： A one-way clutch used in a wind power generation device integrally rotatably connects an input rotating body and an output rotating body to each other in a state in which a rotational speed of the input rotating body exceeds a rotational speed of the output rotating body, and breaks connection between the input rotating body and the output rotating body in a state in which the rotational speed of the input rotating body is lower than the rotational speed of the output rotating body. The input rotating body and the output rotating body are allowed to relatively move along an axial direction, and a maximum allowance of movement is set to be larger than variation of a distance along the axial direction between an input shaft and an output shaft caused by state change.

摘要： A one-way clutch includes: a plurality of engaging elements which restrict relative rotation toward the other side of a circumferential direction by engagement with an inner ring outer circumferential surface and an outer ring inner circumferential surface and which allows the relative rotation along the other side of the circumferential direction by releasing the engagement; and a ring-shaped cage which holds the engaging elements. In a clutch unit, a positioning member which is capable of contact a side surface of the cage in an axial direction and which positions the cage along the axial direction is provided between the one-way clutch and a rolling bearing.

摘要： A one-way clutch used in a wind turbine generator connects an input rotor with an output rotor so that the input rotor and the output rotor are rotatable together with each other when a main shaft rotates in a forward direction and rotation speed of the input rotor is higher than rotation speed of the output rotor, and disconnects the input rotor and the output rotor from each other when the rotation speed of the input rotor is lower than the rotation speed of the output rotor. Further, the wind turbine generator includes a second one-way clutch that permits transmission of force caused by the rotation of the main shaft, to the input rotor when the main shaft rotates in the forward direction, and restricts the rotation of the main shaft when the main shaft tries to rotate in a reverse direction.

摘要： A clutch unit includes a one-way clutch including a plurality of engaging elements which restrict relative rotation of an outside rotating body toward one side of a circumferential direction relative to an inside rotating body by engagement with the outside rotating body and which allow relative rotation toward the other side of the circumferential direction by releasing the engagement. An assembly method for this clutch unit includes: a first step of mounting an engaging member including the engaging elements to the inside rotating body; and a second step of mounting, after the first step, the outside rotating body to a radial outside of the engaging elements while the outside rotating body is rotated relative to the inside rotating body toward the other side of the circumferential direction.
