Definitions

  • the invention relates to a hand tool according to the preamble of claim 1.
  • a power tool is off DE 198 52 137 A known.
  • Eccentric grinding machines which have an electric motor arranged in a housing with an armature shaft pointing in the direction of a grinding disc.
  • the armature shaft is supported on the side facing the sanding pad via an anchor ball bearing in the housing of the eccentric sanding machine.
  • the armature shaft is pressed into a bearing seat of an eccentric sleeve and is rotatably connected thereto.
  • a sanding ball bearing is mounted on the eccentric sleeve, via which the sanding pad is mounted on the eccentric sleeve.
  • a fan of a fan is mounted on the eccentric sleeve in the region of the bearing seat of the armature shaft.
  • the invention relates to a power tool having a motor arranged in a housing with a motor shaft which is mounted on a arranged on a sanding pad side shaft bearing and which is rotatably connected in a bearing seat with an eccentric sleeve, wherein the eccentric sleeve in the axial Direction at least partially protrudes into the shaft bearing and the axial space of the shaft bearing is at least partially, advantageously completely, used for driving connection of the eccentric sleeve. It can be saved axial space and thus an advantageous low center of gravity and a particularly handy hand tool can be achieved. This has a particularly advantageous effect on hand-held power tools, which are guided with one hand by means of a grip formed on the housing.
  • the solution can be applied to various propulsion systems which appear meaningful to a person skilled in the art, such as, for example, pneumatically driven hand tool machines, etc.
  • the solution according to the invention is used particularly advantageously with electrically driven hand tool machines having an electric motor. Electric motors are usually larger and heavier than pneumatic motors, which has a particularly advantageous effect on electrically powered hand tool machines, the saving of axial space and the achievable low center of gravity.
  • a small distance between the shaft bearing and a sanding disc bearing connected to the eccentric sleeve can be achieved by the solution, advantageously a distance between 5 mm and 15 mm. Due to the small distance a favorable flow of forces can be achieved, and vibrations can be avoided.
  • the sanding pad bearing can be arranged in the eccentric sleeve or advantageously on the eccentric sleeve.
  • the flange can be secured in the housing part via various, the skilled person appears useful form-fitting, non-positive and / or material connections, for example via an adhesive connection, screw, latching connection etc.
  • the flange is attached via a press connection in the housing part, a simple and Fast assembly can be achieved and additional hardware can be saved.
  • the flange is fastened on the side facing away from the sanding pad of the shaft bearing in the housing part, whereby an advantageous space utilization can be achieved.
  • the eccentric sleeve is designed in one piece with a fan. Additional components, assembly costs, installation space and costs can be saved. However, it is also possible to attach a separate fan wheel on the eccentric sleeve, for example, to press.
  • the solution according to the invention can be used in all hand-held power tools that appear appropriate to the person skilled in the art, in particular in eccentric grinding machines, vibratory grinding machines, multi-grinding machines, etc.
  • FIG. 1 shows a partial section through an eccentric grinding machine which has an electric motor 12 with an armature shaft 14 arranged in a housing 10.
  • the armature shaft 14 is mounted on a arranged on a sanding pad 16 side facing shaft bearing 18 and is rotatably connected in a bearing seat 20 with an eccentric sleeve 22.
  • the shaft bearing 18 is formed by a ball bearing, but could also be designed as a sliding bearing.
  • the eccentric sleeve 22 protrudes in the axial direction 56 into the shaft bearing 18 or the armature shaft 14 is supported via the eccentric sleeve 22 in the shaft bearing 18 and the axial space of the shaft bearing 18 is fully utilized for the drive connection of the eccentric sleeve 22.
  • the eccentric sleeve 22 forms a bearing 46 for the shaft bearing 18 and a bearing 48 for the sanding plate bearing 24 and is integral with a fan 36 of a fan 32 running.
  • the shaft bearing 18 is supported in a housing part 30 via a flange 28 which surrounds this radially and is formed by a separate component (FIG. 3).
  • the flange 28 is secured via a press connection 34 in the housing part 30 of the fan 32, on the side facing away from the sanding pad 16 of the shaft bearing 18th
  • the shaft bearing 18 is pressed into the flange 28 (FIG. 2).
  • the shaft bearing 18 is on the side facing away from the sanding pad 16 on a collar 38 of the flange 28 to the plant and closes on the sanding pad 16 side facing flush with the flange 28 from.
  • the eccentric sleeve 22 is inserted into the shaft bearing 18 and the armature shaft 14 is pressed into the eccentric sleeve 22.
  • the eccentric sleeve 22 comes with its side facing away from the sanding pad 16 end face 58 on an integrally formed on the armature shaft 14 collar 44 to the plant.
  • the preassembled subassembly consisting of the eccentric sleeve 22, the shaft bearing 18, the flange 28 and the electric motor 12 with its armature shaft 14, are then pressed into a recess 42 of the housing part 30 with a ring plate 40 formed on the flange 28 or in the housing 10 mounted the eccentric grinding and thereby secured axially, radially and against rotation.
  • the sanding pad 16 which forms a preassembled assembly with the sanding pad bearing 24, is pushed onto the bearing 48 of the eccentric sleeve 22, the sanding pad bearing 24 resting on the sanding pad 16 facing away from an integrally formed on the eccentric sleeve 22 stop 50 comes to rest.
  • a hexagonal screw 52 is screwed into the eccentric sleeve 22, with which the grinding disk bearing 24 and the sanding pad 16 are attached to the eccentric sleeve 22 via a support ring 54.
