<p><P>PROBLEM TO BE SOLVED: To eliminate a bearing and a bush of high capacity by removing the point of force (pin) to which load of a connecting rod is applied in a transmission that converts oscillating motion of the connecting rod connected in an eccentric state to an input shaft into intermittent rotation of an output shaft via a one-way clutch. <P>SOLUTION: When the eccentric amount of an eccentric disk 17 with respect to an axis L1 of the input shaft 11 by a speed change actuator is changed, the oscillation angle of the connecting rod 18 is changed and the angle of reciprocating rotation of a driving member 22 is increased and decreased so that the speed change ratio between the input shaft 11 and the output shaft 12 can be changed. A guide shaft 22b of the driving member 22 is slidably engaged in a guide hole 18c of the connecting rod 18, so that the connecting rod 18 does not need to be connected to the driving member 22 via the pin which is the point of force, and the bearing and the bush of high capacity for supporting the load concentrated on the point of force is not required. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
