Document Type and Number:
WIPO Patent Application WO/2005/033553
Kind Code:
A1
Abstract:
A transmission simplified in structure and mechanism and reduced in weight and size, wherein a first rotating shaft (13) to which a first speed change rotating ring (5) is fixed on a same axis and a second rotating shaft (14) to which a second speed change rotating ring (6) is fixed on a same axis are disposed parallel with each other, a support shaft (17) is extendedly disposed between the first speed change rotating ring (5) and the second speed change rotating ring (6), and intermediate transmission rings (16) rotatable and movable in the longitudinal direction of the support shaft (17) are installed on the support shaft (17). The intermediate transmission rings (16) are allowed to abut on the side peripheral face (9) of the first speed change rotating ring (5) and the side peripheral surface (10) of the speed change rotating ring (6) and move along the longitudinal direction of the support shaft (17) in a contact state. The first rotating shaft (13) is rotated by a power device (19), the rotational speed thereof is changed, and the rotation thereof can be transmitted to the second rotating shaft (14).
