Arrangement for adjusting rotational axis of rotatable element, has torsion element that is tightly abutted on pipe made of material with good thermal conductivity

摘要

The arrangement has strand-like torsion element (8) made of shape memory alloy, which is located in axis of rotation. The torsion element is tightly abutted on pipe (9) made of material with good thermal conductivity. An electrical heating element (10) such as positive temperature coefficient (PTC) resistor is mounted outside the pipe.
