摘要:
The present disclosure relates to a linear drive, including: an actuator unit with at least one actuator; two guide elements and a movement element, wherein the movement element is displaceable along both guide elements by a movement generated by the actuator unit as a result of a stick-slip effect. In order to allow a more accurate displacement of the movement element in a compact design of the linear drive, the movement element can be brought into engagement with each of the two guide elements by static friction in order to be displaced along the two guide elements as a result of the stick-slip effect.
