Abstract
The invention discloses a driven wheel overrunning clutch device for a harvester. The device comprises a driven shaft, a driven chain wheel which is arranged on the driven shaft in a sleeved mode, a sliding sleeve which is arranged on the driven shaft and can make axial movement, and a stopping part which is placed on the side, far away from the sliding sleeve, of the driven chain wheel and used for preventing the driven chain wheel from sliding in the axial direction. A clutch structure is arranged between the driven chain wheel and the sliding sleeve. By the aid of the clutch structure, when the driven chain wheel rotates, the sliding sleeve and the driven chain wheel can be combined so as to drive the driven shaft to rotate; when the driven chain wheel stops rotating and the driven shaft rotates continuously and synchronously, the sliding sleeve can be separated from the driven chain wheel. The driven wheel overrunning clutch device for the harvester is simple in structure and easy to manufacture, lowers impact, prolongs the service life of a chain and guarantees efficient work of the harvester.
