SMALL-SIZED CONTINUOUSLY VARIABLE TRANSMISSION

Japanese Patent JPS6141074

A

PURPOSE:To permit the continuously variable speed change with the simple constitution by axially supporting the shafts onto which a gear is fitted and the shafts onto which a sector gear meshed with the above-described gear is fitted between a pair of discs, keeping an interval, and supporting the sector gear by an eccentric body, permitting revolution displacement. CONSTITUTION:Onto a disc A fixed onto a driving shaft 1, a disc B is integrally connected through pins 11... in the state where both discs A and B are opposed, keeping an interval, and a gear 4 and a sector gear 5 are fitted onto three shafts 8 and 9 axially supported rotatably between the both discs A and B, and the both gears 4 and 5 are meshed with each other. A gear 3 is fitted onto the gear 4 through a roller clutch 12, and meshed with a gear integrally formed with an output shaft 2. A bearing 6 is axially supported at the pivot part of the sector gear 5, and engaged with the circular groove of an eccentric plate 7 continuously installed onto the disc B. The amount of eccentricity is varied by shifting the eccentric plate 7 in the vertical direction by a rod 10 fixed onto the eccentric plate 7, and continuously variable speed change is permitted.
