V-BELT CVT TRANSMISSION Russian patent published in 2022 - IPC F16H9/06 F16H55/56 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. Variable speed V-belt transmission consists of a belt, driven and driving pulleys, each of which contains synchronously rotating fixed and movable disks with coaxial hubs, where the movable disks with their hubs are able to move relative to the stationary disks with their hubs along the axis of rotation. In the driven pulley, the movable disk is spring-loaded relative to the fixed one and is equipped with three cams. Fixed and movable disks with hubs, spring, three cams and two plain bearings installed in the inner part of the fixed disk hub form a disk block. In the drive pulley, by means of a hydraulic cylinder, the position of the movable disk is adjusted relative to the fixed one, the hub of which and the hydraulic cylinder are fixed on the drive shaft. Splined guides and sliding bushings are introduced into the hub, installed between the hubs of the movable and fixed disks from the composition of the driving and driven pulleys. In the driven pulley, the disk block is configured to rotate on the hub with a casing installed on it and a drive pulley of the threshing drum, which includes a cam clutch, and the hub is mounted on the counter drive shaft, while the casing with the hub of the movable disk forms a closed cavity in the lubricant.

EFFECT: increased resource and increased reliability of the structure.
