<P>PROBLEM TO BE SOLVED: To provide a power generation device that effectively prevents smearing from occurring in a roller bearing for supporting an output shaft of a speed increasing gear. <P>SOLUTION: This wind power generation device 1 includes: an input rotating body 5 arranged to be integrally rotated on the output shaft 35 of a speed increasing gear 3; an output rotating body 6 arranged to be integrally rotated on a drive shaft 41 of a power generator 4; and a one-way clutch 7 arranged between the input rotating body 5 and the output rotating body 6. The one-way clutch 7 connects the input rotating body 5 to the output rotating body 6 to be integrally rotated with each other while the rotating speed of the input rotating body 5 exceeds that of the output rotating body 6, and disconnects the input rotating body 5 from the output rotating body 6 while the rotating speed of the input rotating body 5 falls below that of the output rotating body 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
