Abstract:
1. A transmission, comprising: a) a rotatable input member, which is rotated by a rotational power source; b) one or more rotatable masses, where said rotatable masses are sprockets; c) a shaft member with an eccentrically offset sprocket for each said rotatable mass, where said shaft member rotatably coupled to a casing, where said rotatable masses are rotatably coupled to said eccentrically offset sprockets by timing belts or timing chains where the centrifugal load of said rotatable masses are held by said timing belts or timing chains; d) said rotatable input member coupled to said rotatable masses by one or more linkages so that rotation of the input member causes said rotatable masses to rotate about said eccentric offset sprockets and said timing belts or said timing chains transfers said centrifugal loads of said rotatable masses to said eccentrically offset sprockets which generates an oscillating torque to said shaft member; e) first and second one-way clutches to convert the said oscillating torque to unidirectional torque are coupled between said casing, said shaft member and an output member, said first one-way clutch and said shaft member drive said output member in the output direction when said shaft member is rotating in the output direction, said second one-way clutch and said casing prevents said shaft member from rotating in the other direction.
