Abstract
Torque limiting device especially applicable to the drive train to cane chopping apparatus in a sugar cane harvester. Abutments associated with the friction members of a band type clutch abut when slip occurs and trip an over-centre device to release the drive. About 360.degree. of slip can occur before the device trips. The drive is re-engaged by reversing the drive thereto.
Claims9
A crop harvesting machine having drivable crop treatment apparatus characterized in that the drive to the crop treatment apparatus is transmitted through a torque-limiting device comprising first and second friction elements, a control mechanism operable to effect driving engagement of the friction elements and to effect release thereof whereby drive may be established and interrupted respectively between the friction elements and actuating means operably attached to the first and second friction elements for actuating the control mechanism to interrupt drive between the first and second friction elements in response to relative movement between the first and second friction elements in one direction.
