摘要：
The inventive utility model relates to agricultural engineering and can be used in the construction of mechanical transmission elements, in particular as part of the threshing drum drive as a driven variator. The technical result is achieved by the fact that the driven variator is mounted on the shaft of the threshing drum and connected to the leading variator by V-belt, including fixed and movable disks with coaxial hubs mutually spring-loaded due to the spring, while movable the disk is equipped with cams, two cams mounted on the fixed disk are introduced into the fixed disk, made in the form of interchangeable pads located at an angle of 180 degrees to each other relative to the axis of rotation of the driven variator, bushings made of polymeric materials and a guide axis, while the cams are fixed with pins and screws, the guide axis is bolted and forms a movable connection with the sleeve, providing synchronous rotation of the movable and fixed disks. The elements of the fixed and movable disks, a spring compressed by a cover that is fixed by a circlip on the hub of the fixed disc, form a block of discs that can rotate on the shaft of the threshing drum due to sliding bearings installed in the inner part of the hub of the fixed disc. rotation of the movable and fixed disks eliminates slipping and turning the belt； placing the guide axis on the big shoulder, ensuring the same clearance between the two teeth of the cam clutch and the cams, allows to reduce critically dangerous loads on the elements of the driven variator during operation and, thereby, increase the resource and increase the reliability of the design.Заявляемая полезная модель относится к сельскохозяйственному машиностроению и может быть использована в конструкциях элементов механических передач, в частности в составе привода молотильного барабана в качестве ведомого вариатора.Технический результат достигается тем, что в ведомый вариатор, установленный на валу молотильного барабана и связанный с вед
