  • an additional housing is provided which has openings to the gear chamber and covers the mouth of the connecting channel on the gear box side.
  • the hand tool according to the invention with the characterizing features of claim 1 has the advantage that the entry of lubricant into the connecting channel is prevented by the centrifugal forces generated during the rotation of the rotary element.
  • the connecting channel in particular the bore, which connects the transmission space to the atmosphere and / or the engine compartment, enables pressure to be reduced in the transmission space in a simple and inexpensive manner.
  • a motor-operated rotary hammer 1 is shown schematically, which is designed and works as described in detail in DE-A-33 29 005 and DE-A-40 00 822, to which expressly for the purpose the disclosure and to avoid unnecessary repetition.
  • the hammer drill 1 contains in a housing 2 an electric motor 3, a gear 4, a striking mechanism 5 designed as an air cushion percussion mechanism and one Tool holder 6 into which a tool 7 suitable for the respective application can be inserted.
  • the motor 3 has a pinion 8, which is always in engagement with an outer ring gear 9 of a clutch gear 10, which is part of a sleeve 30.
  • the gear wheel 10 has a toothing 11 on its end face.
  • the clutch gear 10 is supported in the wobble hub 29.
  • An intermediate shaft 17 runs inside the wobble hub 29 and sleeve 30.
  • a needle bearing 16 is pressed into the clutch gear 10, the clutch gear 10 and the intermediate shaft 17 being relatively displaceable in the region of the needle bearing 16.
  • the intermediate shaft 17 has a thickened central part 18, on the right side facing the clutch gear 10 of which a counter toothing 19 is arranged, which forms a clutch 11/19 with the toothing 11.
  • the left end of the intermediate shaft 17 is axially displaceably mounted in a needle bearing 22 seated in the housing 2.
  • a ball bearing 23 is pressed onto the middle part 18 following the longitudinal toothing 20, on the outer ring 24 of which a switching element 25 engages for the axial displacement of the intermediate shaft 17.
  • an engine compartment 31 is formed, in which the electric motor 3 is contained, and on the side adjoining on the left in FIG. 1, a transmission compartment 32, in which the transmission 4, the striking mechanism 5 and the other elements already explained are included.
  • the housing part 13 separates the engine compartment 31 from the gear compartment 32.
  • the pinion 8 extends through the Housing part 13 into the gear chamber 32 and is mounted within the housing part 13 by means of a ball bearing 26.
  • the ball bearing 26, as is not particularly emphasized, has sealing disks on both sides and, on the side facing the transmission space 32, also has a centrifugal disk 27 which is connected in a rotationally fixed manner to the inner ring of the ball bearing 26.
  • the ball bearing 26 is held with a sliding fit in the housing part 13, an O-ring 54 being arranged between the outer ring and the housing part 13.
  • This design of the ball bearing 26 with double-sided sealing disks, centrifugal disk 27 and O-ring 54 is intended to promote a seal of the gear chamber 32 to the engine compartment 31 in this area.
  • An O-ring 33 serves for further sealing.
  • the rotary hammer 1 has a pressure compensation device 34, which is shown in detail in particular in FIG. 2 and is explained in more detail below with reference to this.
  • the pressure compensation device 34 enables a reduction in the pressure generated in operation in the gear chamber 32 and thus pressure compensation.
  • heat develops during operation of the rotary hammer 1, especially in the gear chamber 32, in particular when the rotary hammer 1 operates in impact mode. Due to the heating in the gear chamber 32, a considerable excess pressure develops, which can be reduced by means of the pressure compensation device 34, and this advantageously with no loss of lubricant within the gear chamber 32.
  • the pressure compensation device 34 advantageously connects the gear chamber 32 to the engine compartment 31 and carries out a pressure compensation of the gear compartment 32 to the engine compartment 31.
  • the pressure compensation device 34 has at least one connecting channel 35 between the gear chamber 32 and the engine compartment 31.
  • Part of the pressure compensation device 34, in particular the connecting channel 35, is at least one bore 36 contained in the housing part 13, which ends at one end 37 in the gear chamber 32 and at the other end 38 in the engine compartment 31 and advantageously parallel to the axis of the pinion 8 through the Housing part 13 runs through.
  • the housing part 13 has in the area of the sleeve 30 with the coupling gear 10 at the end, the compression spring 12 and the intermediate shaft 17 a protrusion 28, for example a pin, which projects towards the gear chamber 32, which is an integral part of the housing part 13 and through which the at least one bore 36 runs , whose end 37 on the gearbox space ends in the region of the end face 39 of this projection 28.
  • a protrusion 28 for example a pin, which projects towards the gear chamber 32, which is an integral part of the housing part 13 and through which the at least one bore 36 runs , whose end 37 on the gearbox space ends in the region of the end face 39 of this projection 28.
  • gear chamber 32 can be vented to the outside, to the atmosphere.
  • a channel 36 ' which is only indicated by dashed lines, a hole in the housing part 13, which leads to the outside, possibly through the housing 2 or in some other way.
  • the channel 36 ′ adjoins the bore section of the bore 36 running to the left in FIG. 2.
  • the pressure compensation device 34 also has in the gear chamber 32 a continuously rotating rotary element 40, by means of which lubricant located in the gear chamber 32 can be thrown radially outwards as a result of centrifugal force.
  • the rotary element 40 is driven by means of the sleeve 30 of the transmission 4, which sleeve is constantly driven by the pinion 8, namely via the compression spring 12, the ends of which engage the sleeve 30 on the one hand and on the rotary element 40 on the other hand in a force-fitting and / or positive manner.
  • the compression spring 12 is e.g. with its last turn held non-positively and / or positively in a bore 41 of the sleeve 30, e.g.
  • the rotary element 40 is continuously driven via the sleeve 30, which is constantly driven by the pinion 8, and the compression spring 12, which is thus driven continuously in a rotating manner, both in the drilling working position and in the percussion drilling and chiseling working position of the rotary hammer 1.
  • the rotary element 40 is located thus always in rotation.
  • the rotary element 40 is spatially upstream of the end 37 of the connecting channel 35, in particular the bore 36, which opens out into the gear chamber 32, the rotary element 40 being able to cover this end 37 in the radial direction.
  • the rotation element 40 is formed from an approximately hat-shaped cover cap 42 which has an end wall 43, an adjoining, approximately cylindrical jacket 44 and an annular flange 45 adjoining the jacket 44.
  • the cover cap 42 engages over the projection 28 of the housing part 13 in the first embodiment with both an axial and a radial distance.
  • the end wall 43 radially covers the end 37 of the bore 36.
  • the cap 42 contains at least one passage 46, for example a bore, in the end wall 43. Dashed lines in FIG. 2 indicate that the cover cap 42 may additionally or instead also include a passage 47 in its jacket 44. Via the respective passage 46, 47, the gear chamber 32 communicates with the interior 48, which is enclosed by the cover cap 42, and via the interior 48 with the end 37 of the connecting channel 35, in particular the bore 36, opening out therein.
  • the considerable overpressure that forms during operation due to heating in the gear chamber 32 can be reduced through the passage 46, 47, the interior 48 and the bore 36 to the atmosphere or to the engine compartment 31, at the same time avoiding the lubricant contained in the gear chamber 32, in particular grease, can escape from the gear chamber 32 in this way and reach the atmosphere or the engine compartment 31, for example. It is thus achieved with simple means and in a cost-effective manner, a reliable sealing of the gear chamber 32 with simultaneous venting, wherein leakage of lubricant, in particular grease, and thus any loss of lubricant is avoided.
  • the rotary element 40 is part of the axial bearing 14, via which the compression spring 12 of the sleeve 30 is axially supported and rotatably supported with the right end in FIG. 2 on the housing part 13.
  • the axial bearing 14 is designed as a roller bearing, in particular a ball bearing. It contains 49 bearing bodies 50 in a bearing cage, e.g. in the form of balls.
  • the axial bearing 14 is supported on the housing part 13 by means of a bearing ring 51 on which the bearing bodies 50 run.
  • the rotary element 40 in particular the cover cap 42, forms a bearing surface 52 on the axial ring surface of the ring flange 45 facing the bearing bodies 50, which bearing surface essentially corresponds to that of the bearing ring 51 and on which the bearing bodies 50 run.
  • the rotary element 40 is instead formed from a disk.
  • the second exemplary embodiment differs from the first with regard to the design of the axial bearing 114, which is designed as a plain bearing in the second exemplary embodiment.
  • the axial bearing 114 has a sliding disc 160, which is axially supported on the housing part 113 via a sealing element 161.
  • the rotary element 140 in particular in the form of the cover cap 142, is axially supported and supported on the sliding disk 160 by the bearing surface 152 provided on the ring flange 145.
  • a sliding sleeve 162 is arranged, which is integral with the sliding washer 160 and centers the cover cap 142 on the projection 128.
  • the sliding disc 160 is pressed onto the projection 128 and the sealing element 161. As shown in FIG. 3, the bore 136, which connects the gear chamber 132 to the atmosphere or to the engine compartment 131, can be reduced to the smallest possible passage cross section in the region of the projection 128 and the centering sleeve 162.
  • the rotating element 140 has at least one radial or tangential groove 163 in the area of the bearing surface 152, which opens radially or tangentially outwards into the gear chamber 132. Furthermore, in the area of the bearing surface 152, the rotary element 140 has a centrifugal device 164 on its circumference, which is formed, for example, from an axially projecting, annular skirt 165.
  • the apron 165 is designed as a truncated cone ring, the inner surface 166 of which widens approximately in the shape of a truncated cone in the axial direction directed towards the housing part 113. Due to the groove 163 and the centrifugal device 164, the sealing and centrifugal effect is further increased.
  • the groove 163 serves as a return groove for any lubricant from the interior 148 radially outward back into the gear chamber 132.
  • the end face of the end wall 143 always remains free of lubricant, in particular grease, due to the centrifugal force during the rotation of the rotary element 140 .
  • lubricant contrary to expectations, pass through a passage 146, 147 in penetrate the interior 148, the lubricant is thrown outwards due to the rotation against the inner surface of the jacket 144, along which the lubricant travels to the axial bearing 114, in particular to the sliding disk 160.
  • the lubricant can then reach the outside radially via the at least one groove 163 and is thrown out and back into the gear chamber 132 via the approximately angular skirt 165. In this case, too, the lubricant penetrating into the interior 148 cannot get into the bore 136.
  • the configuration of the axial bearing 114 as a plain bearing in the second exemplary embodiment in FIG. 3 is even simpler and even more economical than the first exemplary embodiment.
  • the right end of the compression spring 112 is held on a shoulder 167 of larger diameter, the shoulder 167 being e.g. has radially directed driving surface 168 against which the end 169 of the spring 112 can bear in a form-fitting manner, so that the rotatingly driven spring 112 positively entrains and drives the rotary element 140 in one direction of rotation via this end 169 and the driving surface 168.
  • the right end of the compression spring 112 can also be clamped and thus non-positively connected to the rotary element 140 such that the continuously driven compression spring 112 drives the rotary element 140.
