FIELD: agricultural engineering.
SUBSTANCE: drive mechanism has wedge-shaped sheave with hub on cylinder shaft. Hub is composed of two concentric parts positioned for rotation one relative to another. Upper part of hub makes part of sheave and has semi-circular slots arranged on generatrices of receptacle opening. Inner part of hub is attached axially on threshing cylinder shaft and is embraced with closed elliptical slot of semi-circular section. Spherical members are placed in closed elliptical slot to mate with hub outer part. Rotation of two parts of hub one with respect to another enables stabilized process and light-duty operation of engine.
EFFECT: increased efficiency and enhanced reliability in operation.
