摘要： A drill chuck arrangement for connecting a drill bit to a spindle of a drilling machine comprises a spindle member threaded onto the spindle, and a jaw-actuating member mounted at least in part about the spindle member for concentric turning about the latter. A plurality of opposed clamping jaws are movable towards and away from each other in response to the aforementioned concentric turning. The spindle member has a radial bore which receives a portion of an actuating tool having beveled gear means. Upon turning the tool, the beveled gear meshes with a cooperating gear on the jaw-actuating member so as to turn the same relative to the spindle member, and thereby clamp or release a drill bit inserted in between the clamping jaws. A bushing is provided intermediate the spindle member and the jaw-actuating member to prevent binding between these members.

摘要： To reduce operating noise, and particularly the impact of sound pressure waves on the internal structure of the planing machine, the edges defining separating walls against which sound waves may impinge are inclined with respect to the axis of rotation of the cutter (16) or a theoretical line (46) parallel thereto, thereby extending the time of impact of individual pressure waves emanating from the cutter of incremental surface areas of the respective edges (26, 48, 50; 42, 52, 54; 30) to simultaneously attenuate the impact of the pressure waves and the timing of the impact.

摘要： An electronic control and regulating system for AC-operated appliances, especially universal motors and with symmetrical phase control. The control circuit includes among other things an inductive current-voltage converter 9, the primary side 8 of which is connected to the load current circuit and in which, in addition to the converter function, the inductivity of the secondary winding 10 is used and becomes a component of a resonant circuit 20 which is tuned approximately to the frequency of the AC voltage source. The feedback variable of the control system is formed by the resonant circuit voltage, i.e. the resonant circuit impedance, which depends not only on the magnitude of the load current but also on the phase angle of the load current. This quasi-resonance effect makes possible a direct influence of the trigger circuit which consists customarily of a trigger capacitor 13, a load resistor 11 and a trigger diode 15 and is possible without excessive use of additional circuit elements.

摘要： A hand tool machine, in particular a drill machine, has a feeler device for determining the diameter of a tool element to be used with the hand tool machine. For measuring the tool elements prior to insertion into the clamping element of the hand tool machine, a feeler device is provided which is arranged separately from the clamping element and is connected with an indicator. The diameter determined by the feeler device is administered to a control unit which is controlling the driving motor. The control unit can also receive in addition further information concerning the material to be treated by means of an input device. In view of the measuring value with regard to the diameter of the tool element and the administered information concerning the material, the optimum rotary speed for the tool element and consequently for the driving motor is determined and adjusted.

摘要： To prevent bounce of a hammer or plunger element coupled to an insertion blade of a stapling or nailing gun upon return of the plunger element to rest position by a spring (11), the plunger element (4) is in cup shape, sliding about a hollow cylinder (6) which is vented to ambient air (8) at one end, but closed at its other end by a flap-type check valve (9). Upon downward movement of the plunger element, for example under electromagnetic force of a solenoid (2), air can flow freely from the vent opening (8) into the hollow interior and through the then open check valve (9); upon return movement under force of a spring (11), the flap valve (9) will close, however, thus forming an air cushion or air damper and preventing rapid, uncontrolled return of the plunger element to rest position, due to an air throttling path (19) between the outside of the hollow cylinder and the inner surface of the plunger element (4), said air throttling path being defined by the operating clearance between the plunger (4) and the hollow cylinder (6). The hollow cylinder (6) may be constructed as a guide element, unitary with the valve, and made of plastic, the valve being secured by a living hinge to the remainder of the hollow cylinder.
摘要翻译：为了防止当弹簧（11）将柱塞元件返回到静止位置时，联接到装订或钉枪的插入刀片的锤或柱塞元件的弹跳，柱塞元件（4）处于杯状，中空圆筒（6），其在一端被排放到环境空气（8），但在其另一端通过翼片式止回阀（9）封闭。当柱塞元件向下移动时，例如在螺线管（2）的电磁力作用下，空气可以从通气孔（8）自由地流入中空的内部并通过打开的止回阀（9）。然而，在弹簧（11）的作用下的返回运动时，瓣阀（9）将闭合，从而形成气垫或空气阻尼器，并且防止柱塞元件由于空气节流而快速，不受控制地返回到静止位置在空心圆筒的外侧和柱塞元件（4）的内表面之间的路径（19），所述空气节流路径由柱塞（4）和中空圆柱体（6）之间的操作间隙限定。中空圆柱体（6）可以构造为与阀一体并且由塑料制成的引导元件，阀由活动铰链固定到中空圆柱体的其余部分。

摘要： To reduce noise and idling speed of electric motors, particularly series motors, the speed-torque characteristic of the motor is dropped with respect to the loaded speed-torque characteristic, by sensing no-load operation of the motor and deriving a sensed signal, the sensed signal being applied to controlled switches to abruptly change the effective voltage applied to the motor between values corresponding to the no-load speed-torque characteristic, or the load speed-torque characteristic and resulting in the desired speed, in dependence on the value of the sensed signal. Preferably, the operating condition of the motor is sensed by an inductive transducer, and a speed change is obtained by phase control, or half-wave rectification.

摘要： To detect if a tool bit, such as a drill, a saw blade, or the like, upon being worked into a wall, meets a metallic obstruction, such as a conduit, reinforcement rod, hydraulic pipe or the like, an alternating voltage, preferably between 2 and 20 kHz, is coupled through a coupling capacitor (9) to the tool bit, and current flow to the tool bit is detected by a current measurement stage (10; 31, 32) to disconnect energy to the drive motor (5), for example by disabling firing of a thyristor (15), or closing a valve of a compressed-air tool. The coupling capacitor should have a capacity small enough to provide high impedance to network power frequency, and to insure a substantial change in current being supplied to the tool bit holder, typically a chuck, if the tool bit meets a metallic object in the wall. The a-c supply circuit can be formed as part of a trigger circuit for the thyristor, by pulse-energizing a trigger diode (28) upon repetitive charge of a capacitor (26) through a charging network (22, 23, 24, 25).
摘要翻译：为了检测工具钻头（例如钻头，锯片等）在被加工成墙壁时是否遇到金属阻塞物，例如导管，加强杆，液压管等，交流电压，优选地在2和20kHz之间，通过耦合电容器（9）耦合到工具头，并且通过电流测量级（10; 31,32）检测到工具位的电流流动以将能量断开到驱动电动机 5），例如通过禁止烧制可控硅（15）或关闭压缩空气工具的阀。耦合电容应具有足够小的能力，以提供对网络功率频率的高阻抗，并且如果工具头与壁中的金属物体相遇，则确保将电流提供给工具头座（通常为卡盘）的实质变化。 a-c电源电路可以形成为用于晶闸管的触发电路的一部分，通过在电容器（26）经过充电网络（22,23,24,25）重复充电时，通过脉冲激励触发二极管（28）。
