Title:
TRANSMISSION
Document Type and Number:
Japanese Patent JP2010025310
Kind Code:
A
Abstract:

To eliminate a pinion holder disposed in slide contact with a tooth top of a ring gear and a pinion so as to reduce frictional force, in a transmission in which an oscillating movement of a connecting rod eccentrically connected to an input shaft is converted into an intermittent rotation of an output shaft via a one-way clutch.

As the positions of two second pinions 26 are changed together with a carrier 16 by a gear shift actuator of a transmission mechanism, a ring gear 17a is guided by a first pinion 15 and the two second pinions 26, the eccentric quantity of an eccentric disk 17 is changed, a reciprocating stroke of a connecting rod 18 is changed, and a reciprocating rotation angle of a drive member 22 is increased/decreased, so that the gear ratio between an input shaft 11 and an output shaft 12 can be changed. Since the eccentric disk 17 is guided by the first pinion 15 and the two second pinions 26, which can eliminate the need for the pinion holder to guide in slide contact with the eccentric disk 17, reduce the frictional force, and enhance the transmission efficiency of the driving force.
