Variable ratio power transmission

摘要: A variable ratio power transmission in the form of a gear box is described, which input and output shafts can be varied continuously between maximum minimum. The comprises first bevel wheel (40) rotatably mounted connection with U-shaped member (32) on axis (34). pivotable about (34) coupled to (44) via sprag clutch (36). Hence, pivoting movement direction results torque being applied (36) (44), whereas movements opposite has no effect rotation (44). second (50) also (38) operates reverse that An actuating (52) mechanically rotational coupling (63). Rotation (60) produces an orbital motion (63) turn oscillating By varying radius orbit angle through pivots varied, so transmitted wheels (44, 50) independently (52).
