In an armature packet (1) for an electric motor, having a plurality of armature laminations (2, 3), in each of which a plurality of winding slots (4) for receiving an armature winding (5) are embodied, and the winding slots (4) of adjacent armature laminations (2, 3) are located in alignment with one another and form a conduit (6), a better positional fixation of the armature winding (5) is attained by providing that the winding slots (4), associated with one conduit (6), of different armature laminations (2, 3) have different geometries. The same is attained by providing that at least some of the winding slots (4) each have an influx conduit (11), each of which discharges into its region oriented toward the center of the armature packet (1).

A power tool brake mechanism, in particular a portable power tool brake mechanism, includes at least one mechanical brake unit that has at least one brake element mounted rotatably about a rotation axis and at least one actuating unit that has at least one movably mounted actuating element. The actuating unit is configured to activate and/or deactivate the brake unit. The power tool brake mechanism further includes at least one movement converting unit that has at least one movement converting element configured to convert a movement of the actuating element into a movement of a counter-brake element of the brake unit. The movement of the counter-brake element is at least in a direction that is different from a direction extending along the rotation axis of the brake element.
摘要:
A tool-handling device for an insert tool(14) equipped with an at least essentially disk-shaped hub (42), in particular for a hand guided angle grinder (32) or a hand-guided circular saw, having a drive shaft (16) and a drive device (12) equipped with at least one locking element(20) that is supported so that it is able to move in relation to a spring element (18) in order to fix the insert tool (14) in a form-locked manner in the circumference direction (50, 52).The drive shaft (16) has at least one form-locking element (100) formed onto it in a non-cutting manner in order to connect it in a form-locked manner in the circumference direction (50, 52) to a drive torque-transmitting mechanism of the drive device (12).
摘要:
The invention relates to a toothed wheel of a gear drive, particularly for electric hand machine tools, comprising a toothing and a damping element made of an elastic material, the element being disposed in a recess of the toothed wheel. The object of the invention is to improve the effectiveness and the operational safety of the damping element on a toothed wheel with little effort in order to increase the service life of the gear drive. The task is solved by the toothed wheel (1) having a recess (5) penetrating the toothing (2).
