A crank device or crank drive is disclosed which has a crankshaft, into which a variable first force can be introduced by way of a transmission element over a variable first lever spacing. Here, the first variable force has a predefined profile and/or predefined change. A profile of the first variable lever spacing is designed in a manner which is dependent on the predefined profile of the first variable force in such a way that an effect of change in the first variable force on the crankshaft is at least partially compensated for. The compensation is provided over a rotational range of the crankshaft, which is preferably less than one revolution of the crankshaft.
