- an "axial chip removal” is to be understood as a production method in which a chip removal takes place at least substantially and advantageously exclusively by means of a translatory relative movement in at least one axial direction between a component, in particular the torque transmission means, and a tool, wherein preferably The drive bearing is preferably, together with a wobble drive, for converting a rotational movement of a shaft, such as an intermediate shaft, into a reciprocating motion to a generation, or at least no substantial relative rotational movement between the torque transmitting means and the chip removal tool provided an axial impact pulse.
- the torque transmission means is formed integrally with the drive bearing, whereby additional components, space, assembly costs and costs can be advantageously saved.
- integrally formed is here to be understood in particular integrally formed and / or that the drive bearing and the torque transmitting means form a single unit, which is made of one piece.
- an advantageous torque transmission with a simultaneous storage of the torque transmitting means on an axle or a shaft, such as an intermediate shaft of the transmission device can be achieved if the transmission contour is arranged on a radially outwardly directed surface of the torque transmission means.
- the torque-transmitting contour it is also conceivable to arrange the torque-transmitting contour on a radially inwardly directed surface and / or on an end face of the torque-transmitting means.
- the transmission contour has at least two transmission elements which are arranged uniformly spaced in a circumferential direction of the torque transmission means, whereby in particular a uniform force transmission or a uniform transmission of the torque from another component to the torque transmission means can be.
- the hand tool machine comprises a gear element on which the torque transmission means is rotatably mounted, cost-effective and component-saving mounting on an already existing component, the gear element, required for functioning of the gear device can be achieved.
- the transmission element is preferably formed by an axle and / or particularly advantageously by a shaft, such as an intermediate shaft.
- the torque transmission means have at least one punching free recess, whereby a structurally simple production can be achieved by means of a stamping process.
- the punching clearance is particularly advantageously arranged on a side of the torque transmission means facing the drive bearing.
- FIG. 1 shows an inventive, formed by a hammer drill hand tool in a side view
- Fig. 2 shows a transmission device of the power tool in a side view
- Fig. 3 shows a drive bearing of the transmission device in a
- FIG. 1 shows a hand-held power tool 10 formed by a hammer drill.
- the hand tool 10 comprises a housing 34 and in a front area a tool holder 36 for receiving a tool.
- the handheld power tool 10 comprises a main handle 38 for actuating the hand tool 10 and for transmitting power from an operator to the hand tool 10.
- the hand tool 10 has a drive unit 40 formed by an electric motor for generating a torque .
- the torque of the drive unit 40 which is formed by a drive torque, is transmitted via a transmission device 12 of the handheld power tool to a pneumatic percussion mechanism 42, which is shown only partially for the sake of clarity, and / or to a rotating output means formed by a hammer tube 44 (FIG ).
- FIG. 2 shows a partial region of the handheld power tool 10 with the transmission device 12.
- the transmission device 12 comprises a gear formed by an intermediate shaft 46.
- transmission element 28 via which the torque of the drive unit 40 is transmitted to the striking mechanism 42 and the hammer tube 44 during operation of the power tool 10.
- a drive bearing 14 and a gear unit 48 of the transmission device 12 are mounted on the intermediate shaft 46.
- the drive bearing 14 converts a rotational movement of the intermediate shaft 46 into an axial movement for generating a shock pulse and transmits this movement to the striking mechanism 42.
- the gear unit 48 serves to transmit the torque from the intermediate shaft 46 to the hammer tube 44 or on a rotatably connected to the hammer tube gear 50th
- the drive bearing 14 For transmission of the torque to the drive bearing 14, the drive bearing 14 has a torque transmission means 16 with a transmission contour 18.
- the drive bearing 14 and the torque transmitting means 16 are integrally formed and rotatably supported on the intermediate shaft 46.
- the torque transmitting means 16 is arranged along the power flow direction 56 of the intermediate shaft 46 at a driven-side end 62 of the drive bearing 14.
- the drive bearing 14 also has a bearing sleeve 52 and a wobble finger 54, wherein the wobble finger 54 is mounted on the bearing sleeve 52. When the bearing sleeve 52 rotates about one axis of rotation 78 of the intermediate shaft 46, the wobble finger 54 leads along the axis of rotation
- the transfer contour 18 of the torque transmitting means 16 has four transmission elements 22, 24, 64, 66 disposed on a radially outward surface 20 of the torque transmitting means 16.
- the transfer contour 18 of the torque transmitting means 16 is made by a punching process with an axial chip removal.
- the torque transmission means 16 in a drive bearing 14 facing side 32 on a punching recess 30.
- the punching free recess 30 has a smaller diameter 70 than a root diameter 68 of the torque transmission means 16 (FIGS. 3 and 4).
- the torque of the intermediate shaft 46 is transmitted in the operation of the manual power tool 10 via a torque transmission means 72 of the intermediate shaft 46 to the torque transmitting means 16 of the drive bearing 14 to the drive bearing 14.
- the torque transmission means 72 of the intermediate shaft 46 has an identical transmission contour 74 as the transmission contour 18 of the torque transmission means 16 of the drive bearing 14.
- the torque transmission means 72 of the intermediate shaft 46 in the power flow direction 56 after the torque transmission means 16 of the drive bearing 14 rotatably on the intermediate shaft 46 is arranged ( Figures 2 and 3).
- a transmission sleeve 76 is slidably supported along the force flow direction 56 or counter to the force flow direction 56 (FIG. 2).
- the transmission sleeve 76 an inner contour, not shown, which corresponds to the transmission contours 18, 74 of the two torque transmission means 16, 72.
- the transmission sleeve 76 is displaced by an operator of the power tool 10 by means of an actuating element, not shown, against the force flow direction 56, the transmission sleeve 76 is in a further switching position with an exclusive overlap with the torque transmission means 16 of the drive bearing 14 and a torque transmission from the intermediate shaft 46 the drive bearing 14 and a torque transmission between the two torque transmission means 16, 72 is interrupted.
