Abstract
788,963. Variable-speed gearing. BERT, M. D. A. Nov. 25, 1955 [Nov. 25, 1954; Nov. 26, 1954; Nov. 14, 1955], No. 33845/55. Class 80 (2). A variable-speed gear comprises a driving- shaft 2 with two expanding pulleys 3, 4, the inner cheeks 3<SP>1</SP>, 4<SP>1</SP> being fixed to the shaft and the outer cheeks 3<SP>2</SP>, 4<SP>2</SP> being secured to one another and axially movable. Driven pulleys 7, 8 are mounted on coaxial shafts 9, 10, the outer cheeks 7<SP>1</SP>, 8<SP>1</SP> being fixed to the shafts and the inner cheeks 7<SP>2</SP>, 8<SP>2</SP> being free on their shafts but axially movable together. The speeds of the driven shafts 9, 10 are varied inversely upon axial movement of a movable cheek. The driven shafts 9, 10 may each have a plurality of expanding pulleys belted to corresponding pulleys on the driving-shaft 2. In a modification the pulleys 7, 8 are connected respectively to the annulus and planet carrier of an epicyclic gear, the sun gear being fixed to a final driven shaft. In another modification the pulleys drive respectively a sun-gear and planet carrier of a bevel differential gear, the second sun gear being fixed to a final driven shaft.
