<p>The crank device has a part (2), which can be rotated about an axis, and a crank part (1), the two parts being connected to one another by engagement similar to that in a bayonet catch. Two eccentrics (7, 10) are rotatably mounted in the crank part (1). Each eccentric has a pin (8, 11) eccentric to its axis of rotation, each pin engaging in an associated slot (9, 12) in the rotatable part (2). The crank part (1) can be adjusted relative to the rotatable part (2) by rotating the two eccentrics, it being possible to adjust both the angular position of the crank part and its radial position relative to the axis of rotation of the device. This enables adjustment of the angular position and of the lift of a pin (4) connected to the crank part (1).</p> |
