A stepless transmission of the non-friction type is provided using intermeshing non-circular gears. The transmission is made up of a number of angular velocity modulators each having first, second, and third shafts. Each shaft carries a non-circular gear thereon which meshes with the gear of a succeeding shaft. The angular velocity ratio omega of the third shaft of each modulator relative to the first shaft depends on the pitch curve of the intermeshing non-circular gears and on the position of the third shaft relative to the position of the first and second shafts. By changing the position of the third shaft the angular velocity ratio omega of the modulator can be steplessly varied. The output of the third shafts of each modulator are combined onto a common shaft by one the clutches to provide a continuous output. The position of the third shafts, and thus the overall ratio of the transmission, may be controlled automatically by a spring. |
