GRIPPING DEVICE HAVING AN ACTUATOR THAT IS EQUIPPED WITH SHAPE MEMORY ELEMENTS

摘要

The invention relates to a gripping device comprising gripping element supports (50, 51) carrying gripping elements (1, 2). The gripping element supports and at least one actuator (60, 70) equipped with shape memory elements (81, 82) are mounted in a gripper housing (10) and the one or more actuators act upon at least one mobile gripping element support either directly or via at least one transmission, thereby displacing the one or more gripping elements between an open and a closed position. The inventive gripping device requires little space, has a reduced dead weight and can be opened and closed quickly when prompted and in an almost wear-free manner.
