Abstract: A continuously variable transmission includes an input shaft and a shaft journal eccentrically connected thereto on which a transmission element is bearing supported, as well as an output shaft which is connected to the transmission element via a constant velocity joint. The transmission further includes a housing and a pulley accommodated in it having two axially displaceable pulley wheels spaced apart from each other and which are fixed in the housing in the direction of rotation, as well as an adjusting mechanism for varying the space between the two pulley wheels. The transmission element is located between the two pulley wheels and is formed by a ring that rolls down in the pulley on rotation of the input shaft.

Abstract: A mechanical transmission (1), comprising:—a first shaft (2)—a second shaft (3) wherein the first shaft and the second shaft are mutually connected via at least one push belt (8), which push belt (8) has a fixed position relative to the first and second shafts. The use of the push belt results in a play-free transmission, the transmission ratio of which can be easily modified.

Abstract: The invention relates to a mechanical transmission, which transmission includes guide members for realizing a rotational translating movement of a wheel which is connected to an output shaft and which makes contact with an endless belt of mutually abutting push links, which guide members are assembled from at least two linear guide tracks received mutually perpendicularly in the same plate and guide elements co-acting with the linear guide tracks, wherein guide elements are connected to the wheel for rotational translation and guide elements are rigidly connected to the frame whereby the plate is movable in linear manner relative to the frame and the wheel is displaceable in linear manner relative to the plate.

Abstract: The invention relates to a mechanical gearing. This comprises a frame, a first shaft mounted rotatably on the frame and carrying a pair of friction wheels which are disposed at a distance from each other and which have mutually facing friction surfaces together converging outward, a second shaft which is mounted on the frame parallel to but eccentrically relative to the first shaft and which carries a friction wheel which has an internal annular friction surface situated axially between the friction wheels of the first shaft, and a closed belt of mutually abutting push links. The belt forms on mutually opposite sides surfaces co-acting with the pair of friction wheels and on a radially outermost surface forms a surface co-acting with the single belt engaging wheel.
