Fastening device and method, as well as device for generating percussions

A method for fastening a first object on a second object, comprising a) providing the second object with a recess, b) inserting into the recess a sleeve with comprising a first load application means for the first object, the sleeve also comprising an abutment for an outer surface of the second object, and a passage, wherein the passage comprises an insertion section that lies adjacent to the first load application means and an expansion section, c) inserting an arbor into the insertion section, wherein the expansion section comprises a contraction that is smaller than the outside dimensions of the arbor, and d) driving the arbor into the expansion section such that the region of the sleeve inserted into the recess is expanded against the recess.

A device for generating percussions on a fastening element, comprising a supporting means for supporting the device on a housing of a drill in a rotationally rigid fashion, a power take-off means for tapping a rotational movement of a rotatively driven drill chuck of the drill, a striking element for transmitting percussions to the fastening element, and a striking mechanism for converting a rotational movement of the power take-off means into a linear movement of the striking element.
