Abstract
A hand-held tool gear mechanism unit includes a drive gearwheel, an output gearwheel, and a connecting unit. The output gearwheel has a rotational axis spaced apart radially from a rotational axis of the drive gearwheel. The connecting unit is configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio. The connecting unit is configured to couple the drive gearwheel and the output gearwheel such that they can be moved relative to one another about a pivot axis.
Claims14
A hand-held tool gear mechanism unit, comprising:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- and
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio,
- wherein the connecting unit couples the drive gearwheel and the output gearwheel in such a way that the drive gearwheel and the output gearwheel are pivotable relative to one another about a pivot axis.
A hand-held tool, comprising:
- a hand-held tool gear mechanism unit, including:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- and
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio,
- wherein the connecting unit couples the drive gearwheel and the output gearwheel in such a way the drive gearwheel and the output gearwheel are pivotable relative to one another about a pivot axis.
The hand-held tool according to claim 13, further comprising a machine housing having an overall length of less than 180 mm.
A system comprising:
- a hand-held tool, including:
- a hand-held tool gear mechanism unit, including:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio;
- and
- a coupling apparatus configured to produce a connection to the hand-held tool,
- wherein the connecting unit couples the drive gearwheel and the output gearwheel in such a way the drive gearwheel and the output gearwheel are pivotable relative to one another about a pivot axis, and
- wherein the coupling apparatus is further configured so that the connection is terminable in response to an operator action.
