Abstract
A gear assembly for a square baling press. The gear assembly drives a ram arranged movably between end positions in a pressing channel of the square baling press and at least one additional working unit of the square baling press. The gear assembly comprises two side gears and at least one reduction gear that is downstream from the particular side gear and may be connected on the output side to a crankshaft on which the ram is mounted. At least one flywheel is interposed between the particular side gear and the reduction gear downstream thereof. At least one of the reduction gears comprises a shiftable overload clutch which is designed to brake the reduction gears downstream from the flywheels to a standstill when a mechanical overload occurs.
Claims18
A gear assembly for a square baling press configured to drive a ram positioned movably between end positions in a pressing channel of the square baling press and at least one additional working unit of the square baling press, the gear assembly comprising:
- two side gears;
- at least one reduction gear that is downstream from at least one of the two side gears and that is configured to connect on an output side to a crankshaft on which the ram is mounted;
- at least one flywheel positioned between the at least one of the two side gears and the at least one reduction gear downstream thereof;
- and
- at least one shiftable clutch device positioned between the at least one flywheel and the at least one reduction gear connected downstream thereof;
- wherein the at least one of the reduction gear comprises at least one shiftable overload clutch configured to brake the at least one reduction gear downstream from the at least one flywheel to a standstill responsive to a mechanical overload;
- and
- wherein the at least one shiftable clutch device is configured to be in a disengaged shift position during braking.
A gear assembly for a square baling press configured to drive a ram positioned movably between end positions in a pressing channel of the square baling press and at least one additional working unit of the square baling press, the gear assembly comprising:
- two side gears;
- at least one reduction gear that is downstream from at least one of the two side gears and that is configured to connect on an output side to a crankshaft on which the ram is mounted;
- at least one flywheel positioned between the at least one of the two side gears and the at least one reduction gear downstream thereof, wherein the at least one of the reduction gear comprises at least one shiftable overload clutch configured to brake the at least one reduction gear downstream from the at least one flywheel to a standstill responsive to a mechanical overload;
- and
- a control device configured to:
- automatically detect the mechanical overload;
- and
- responsive to automatically detecting the mechanical overload, actuate the at least one shiftable overload clutch to brake the at least one reduction gear downstream from the at least one flywheel.
A square baler comprising:
- a drivetrain comprising a gear assembly and configured to drive one or more working units of the square baler, and to drive a ram positioned movably between end positions in a pressing channel of the square baler;
- wherein the gear assembly comprises:
- two side gears;
- at least one reduction gear that is downstream from at least one of the two side gears and that is configured to connect on an output side to a crankshaft on which the ram is mounted;
- at least one flywheel positioned between the at least one of the two side gears and the at least one reduction gear downstream thereof;
- and
- at least one shiftable clutch device positioned between the at least one flywheel and the at least one reduction gear connected downstream thereof;
- wherein the at least one of the reduction gear comprises at least one shiftable overload clutch configured to brake the at least one reduction gear downstream from the at least one flywheel to a standstill responsive to a mechanical overload;
- and
- wherein the at least one shiftable clutch device is configured to be in a disengaged shift position during braking.
