Definitions
- the invention relates to an electric hand tool for rotating tools Safety clutch, which in critical operating conditions the much rotational energy separating electric motor from the rest of the power transmission chain, in particular with a hammer drill.
- Electric hand tools such as rotary hammers are usually made by a rapidly rotating one and thereby conveys a lot of rotational energy storing via its moment of inertia Electric motor driven.
- the drive energy decay sufficiently quickly or the power transmission chain between the rotational energy storing electric motor and the tool can be separated sufficiently quickly. at Electric hand tools of greater power sound the drive energy without additional measures not going off fast enough.
- clutches are interposed, which in are known in many different ways.
- to Power transmission in the engaged state mostly serve radially outside of the two Coupling coaxial shafts arranged coupling means, which have static friction mediated by the contact force cause a frictional connection.
- the Slip clutch according to EP694706 can be rotated radially outside by two coaxially interlocking hollow shafts arranged around non-positive coupling means, which slide along each other when an adjustable static friction is exceeded.
- the object of the invention is to implement a safety coupling directly on the high-speed rotor shaft, advantageously only a small axial extension the height is due to the integration of the safety coupling.
- Another aspect consists in actively braking the rotor.
- the safety clutch is a slip-free one in normal operation Co-rotating and guaranteeing free rotation of both shafts in critical operating conditions, formed between the rotor shaft and the pinion shaft.
- the rotor shaft engages axially into a, coaxially rotatably mounted on this, pinion shaft, this inner bearing is advantageously designed as a plain bearing, which is further advantageously with a central ball centered with respect to the common axis of rotation and with sufficiently long axial Sliding surfaces for tilt-free takeover of those picked up by the pinion Transverse forces is provided.
- the safety clutch is advantageously designed as an electromagnetic clutch, at which the, in each case at least in the radially outer side of the mutually facing end faces made of ferromagnetic material, rotor disc rotatably on the pinion shaft and the armature disk is arranged in a rotationally fixed manner on the rotor shaft and in normal operation by means of a, advantageously arranged in the radially outer on the housing, current-carrying magnetic coil generates magnetic flux against a spring force axially pulled against each other and with respect to the rotational movement against each other be positively connected.
- the most non-ferromagnetic Bearing plate of the housing mounted hollow cylindrical magnet coil which in turn for Coupling of the magnetic flux usually with respect to three free sides of the Rotor disk is surrounded, inside the outer bearing of the pinion and the rotor shaft, whereby a nesting of this outer bearing of the pinion and the rotor shaft, the armature disk and the solenoid coil are formed in a narrow axial area and thus only a small axial extension of the overall height through the integration of the Safety clutch is due.
- the armature disk which is designed as a cup-shaped clutch cover, further advantageously has facing, axial counter surface of the armature plate in the radially outer region Friction lining, which mediates in critical operating conditions, via the spring force axially biased by the electromagnetic clutch inside the armature plate Spring comes into frictional contact with the rotating armature disk and thus over the electric motor brakes the armature disk to a standstill and thereby its high rotational energy dissipated.
- the solenoid can be attached to the end shield of the housing and together with the The rotor disk and the pinion shaft are preassembled. This will be in a next one Work step the rotor shaft together with the armature disk and also as dust protection serving housing cover inserted.
- Fig. 1 shows a schematically marked in its entirety Electric hand tool 1 an electric motor 2 in a housing 3, the first one Gear stage of a gear driving pinion 4 and one, between this and the Electric motor 2 arranged, safety clutch 5.
- Safety clutch 5 advantageously designed as an electromagnetic clutch with a Magnetic coil 6, with an aborting clutch disk designated as a rotor disk 7 and a driving clutch disk designated as armature disk 8.
- the Hollow cylindrical magnet coil 6 includes a radial outer bearing 9 with the Pinion 4 integrally connected pinion shaft 10, the inside of which on the part of the side opposite the pinion 4 is connected in a rotationally fixed manner to the electric motor 2 Receives rotor shaft 11 and coaxially rotatable in an inner bearing 12, which as Plain bearing designed with a centering ball and with sufficiently long axial Sliding surfaces for tilt-free takeover of those picked up by the pinion 4 Transverse forces is provided.
- an inner bearing 12 as Plain bearing designed with a centering ball and with sufficiently long axial Sliding surfaces for tilt-free takeover of those picked up by the pinion 4 Transverse forces is provided.
- the outer bearing 9 arranged in the axial engagement area are both the rotor shaft 11 and, mediated via the inner bearing 12, the Pinion shaft 10 rotatably mounted in the housing 3, one with respect to the electric motor 2 opposite rotor bearing 13 absorbs the transverse forces.
- the rotor disk 7 or the armature disk 8 is surrounded inside External bearing 9 of the pinion shaft 10 and the rotor shaft 11, whereby a Nesting of this outer bearing 9 of the pinion shaft 10 and the rotor shaft 11, the rotor disk 7 and the magnet coil 6 in a narrowly defined axial area arises.
- the Rotor shaft 11 with the armature disk 8 and that designed as a clutch cover Counter surface 16 is in the magnet coil 6 fastened to the end shield 14 of the housing 3 as well as in the inner bearing 12 of the pinion shaft 10 and the rotor disk 7 attached thereto insertable in the direction of the end shield 14.
