    Abstract: A power tool transmission device includes a base, a switch portion, a vibration member, a press portion, a transmission shaft and a casing. When the projections press the position plates, bosses on the position plates engage ribs formed outside the outer ring so as to limit the rotation of the outer ring and when the first gear and the second gear are intermittently disengaged with each other, a vibration effect is provided to the transmission shaft.

    Abstract: Method for the open-loop and closed-loop control of a power tool, in particular a chipping hammer, having a drive, a control device, a sensor device, a transmission device and a handle apparatus, wherein the handle apparatus contains a lever element with a signal transmitter, said lever element being pivotable relative to the sensor device. The method includes: sensing a first and second position of the signal transmitter by the sensor device; determining an acceleration of the signal transmitter from the first position to the second position by the control device; setting a first rotational speed for the drive by the control device for the output of a first impact energy value of the transmission device when the determined acceleration reaches a first predetermined threshold value or setting a second rotational speed for the drive by the control device for the output of a second impact energy value of the transmission device when the determined acceleration reaches a second predetermined threshold value. A handle apparatus on a power tool, in particular a chipping hammer, is also provided.

    Abstract: A hammer drill (100) comprises an electric motor (110), a piston (127) as a driving member and a controller (199) which controls and drives the electric motor (110). The piston (127) is reciprocated by rotation of the electric motor (110) and thereby a hammer bit (119) is driven in its longitudinal direction. The hammer bit (119) is moved forward in response to a forward movement stroke of the piston (127) and thereby a hammering operation is performed by the hammer bit (119). The controller (199) sets a duty ratio of a driving pulse signal which drives the electric motor (110) in the forward movement stroke of the piston (127) to be larger in order to prevent a reduction of a rotation speed of the electric motor (110) due to a load applied on the electric motor (110) during the forward movement stroke of the piston (127).

    Abstract translation: 锤钻（100）包括电动机（110），作为驱动构件的活塞（127）和控制和驱动电动机（110）的控制器（199）。 活塞（127）通过电动机（110）的旋转而往复运动，从而使锤头（119）在其长度方向上被驱动。 响应于活塞（127）的向前移动行程，锤钻头（119）向前移动，从而通过锤钻头（119）执行锤击操作。 控制器（199）将活塞（127）的前进行程中驱动电动机（110）的驱动脉冲信号的占空比设定得较大，以防止电动机的转速降低 （110）在活塞（127）的向前移动行程期间由于施加在电动机（110）上的负载而产生。

    Abstract: A drill includes a housing with a motor coupled to an output spindle via a transmission. A mode collar can be rotatably mounted on the housing for movement that corresponds to different modes of operation. The mode collar can be coupled to an electronic switch to operate a movable member thereof. The coupling can include a switch housing including a slide member, an actuation spring member and a return spring member. The mode collar can have a cam surface and a cam follower in the form of a shift pin that moves the slide member, causing actuation of the switch. The actuation spring member provides a biasing force that is sufficient to overcome a biasing force of a switch spring member to move the movable member into the actuated position. The mode collar can also enable and disable contact between a fixed hammer member and a movable hammer member mounted around the output spindle.

    Abstract: A percussion mechanism for a repetitively hammering hand power tool in the form of a rotary hammer has a striker movable axially forward and backward in a guide barrel and imparting impacts directly and without any intermediate parts to an end section of a tool bit that is insertable into the hand power tool, a device that exerts pressure on the striker, by which the striker is capable of being set into a forward motion in the direction of the tool bit, a blocking element, with which the striker is blockable in its forward motion, and the striking frequency of the striker is adjustable by controlling the blocking time of the blocking element, so that the striking frequency of the striker depends on how long the blocking element blocks the forward motion of the striker.
