摘要:
Eine längs einer Schlagachse zumindest teilweise schlagende und drehende Handwerkzeugmaschine mit einem bezüglich einer vibrierenden Schlagwerksbaugruppe vibrationsentkoppelten Führungshandgriff mit einem Motorschalter (5) zur Motorsteuerung, dem zur Arretierung ein Arretierschalter (7) zugeordnet ist, der in einem Schaltbereich (X) versetzbar ist, und in der Schlagwerksbaugruppe (2) ein Betriebsmodiwahlschalter (3) angeordnet ist, der ein Schaltgestänge (9) versetzt, wobei das Schaltgestänge (9) einen Anschlag (10) aufweist, der in einem drehenden Betriebsmode in den Schaltbereich (X) hineinragt.
摘要:
A power drill with percussive drilling, drilling and screwing functions has a gear mechanism for transmitting the driving movement of a driving unit to a tool spindle (4). Also provided are two latching elements (16, 17), which in the percussive drilling position are in latching engagement and in the drilling or screwing position are disengaged. A mode setting device (7) has a rotatable supporting ring (8) and a pressure ring (9), which is coupled with the supporting ring (8) for rotation therewith and in the screwing position is held axially movably on the gear casing (3).

A handle assembly for a power tool is disclosed. The handle assembly has a handle (84), a metal strip (82) for releasably mounting the handle assembly to the housing of a power tool, and a fastening mechanism (80, 100, 104) for tightening and loosening the metal strip on the housing of the power tool. Vibration dampers (124, 126) are located between the handle and the fastening mechanism to damp vibrations transmitted from the fastening mechanism to the handle. Limited rotation of the handle relative to the metal strip is possibly, but rotation beyond predetermined limits causes the fastening mechanism to tighten and/or loosen the metal strip on the housing.

摘要:
A drill (10) includes a housing (14) and a motor (20) coupled to an output member (152) by a transmission (22). The transmission (22) can selectively couple the output member (152) to an output spindle (40) through a low speed output gear (120) or a high speed output gear (122) for rotating the output spindle (40) at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch (178) that limits the speed of the motor (20). A rotatably fixed hammer member (102) and a rotatable hammer member (100) can be mounted around the output spindle (40). A mode collar (26) can be rotatably mounted on the housing (14) and around the output member (40) for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission (22) operates in the high speed mode.
摘要:
A multi-mode drill including a transmission (22) to transfer torque from an output member of a motor (20) to an output spindle (40). A transmission housing encloses the transmission (22) in an interior cavity formed by a gear case shell (149) and a cover plate (150). The cover plate (150) can be coupled to the outer shell (149) via screws. A static shift rod (144) can be supported at one end by the cover plate (150). A shift bracket (132) can be mounted on the shift rod (144) and biased to a mode position by a biasing member (148) exerting a force between the shift bracket (132) and the cover plate (150). A shift pin (92) can be supported adjacent one end by the cover plate (150) and biased to a mode position by a biasing member (148) exerting a force between the shift pin (92) and the cover plate (150). A spindle biasing member can bias the output spindle (40) against the cover plate (150). The shift pin (92) can actuate an electronic switch (178). A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.
