Publication number: 20090278361Abstract: When a rotation frequency of a rotary shaft 2 is not more than a predetermined value, a clutch 7 connects the gearing systems 6 and 8 with each other. Then, the rotation from the rotary shaft 2 is accelerated through the gearing system 6, clutch 7, and gearing system 8, and is transmitted to the rotary shaft 4. At this point, a freewheel clutch 5 disconnects the rotary shafts 2 and 4 from each other. On the other hand, when the rotation frequency of the rotary shaft 2 surpasses the predetermined value, the clutch 7 disconnects the gearing systems 6 and 8 from each other. Then, the rotation frequency of the rotary shaft 4 drops. When the rotation frequency of the rotary shaft 2 equals that of the rotary shaft 4, the freewheel clutch 5 connects the rotary shafts 2 and 4 with each other, thereby transmitting the rotation from the rotary shaft 2 as it is to the rotary shaft 4 via the freewheel clutch 5.Type: ApplicationFiled: October 11, 2006Publication date: November 12, 2009Applicant: SHINKO ELECTRIC CO., LTD.Inventors: Kazuo Okubo, Sumihiro Arima
