摘要: Provided is a striking tool which is capable of switching between operating modes while preventing excessive reaction torque from acting on a tool body. The striking tool comprises a tool body (103); a motor (111) housed in the tool body (103); striking action drive mechanisms (113, 115) which are driven by the motor (111) and strike a tool bit (119); a rotational drive mechanism (117) which is driven by the motor (111) and causes the tool bit (119) to rotate; an operating mode switching member (171) which switches between a first operating mode wherein the tool bit (119) performs the striking operation and a second operating mode wherein the tool bit (119) performs rotational operation at a minimum; and a clutch (134) which transmits and cuts off torque between the motor (111) and the rotational drive mechanism (117). The clutch (134) is configured such that, if the first operating mode is selected, a switch is made to a torque cut-off state wherein torque transmission between the motor (111) and the rotational drive mechanism (117) is cut off, if the second operating mode is selected, a switch is made to a torque transmission state wherein torque is transmitted between the motor (111) and the rotational drive mechanism (117), and that, in a state wherein the switch to the torque transmission state is made, torque transmission between the motor (111) and the rotational drive mechanism (117) is cut off in response to the occurrence of a predetermined load when carrying out a machining operation.

摘要: Die Handwerkzeugmaschine (1) hat einen Werkzeughalter (2) zum Haltern eines Werkzeuges, einen Elektromotor (6), eine Welle (16), die den Werkzeughalter (2) und den Elektromotor ( 6) verbindet und eine Schutzeinrichtung (14) zum Stoppen des Werkzeughalters (2) bei einer unbeherrschten Situation. Die Schutzeinrichtung ( 14) beinhaltet einen Sensor (33) zum Erkennen der unbeherrschten Situation, eine schaltbare Stromquelle (31) und eine normal-schließende Magnetbremse (15). Die schaltbare Stromquelle (31) gibt ansprechend auf Signale des Sensors (33) einen von Null verschiedenen ersten Strom (I1) bei Nicht-Erkennen einer unbeherrschten Situation aus; die Stromquelle (31) gibt keinen oder einen von dem ersten Strom (I1) verschiedenen zweiten Strom (I2) bei Erkennen einer unbeherrschten Situation aus. Die normal-schließende Magnetbremse (15), greift an die Welle (16) an. Die normal-schließende Magnetbremse (15) übt bestromt mit dem ersten Strom (I1) kein Drehmoment auf die Welle ( 16) aus. Die normal-schließende Magnetbremse (15) übt unbestromt oder bestromt mit dem zweiten Strom (I2) ein der Drehbewegung der Welle (16) entgegenwirkendes Drehmoment aus.
