Definitions

  • the invention relates to a drilling and / or chisel device with a striking mechanism a wobble pin of a wobble mechanism is driven.
  • a drilling and chiseling device is known, the striking mechanism and whose tool spindle is driven by an electric drive motor.
  • a wobble mechanism is arranged between the drive motor and the striking mechanism, that consists of a gear shaft with two bearings, one on the gear shaft non-rotatably arranged hub body, one arranged on the hub body, compared to this freely rotatable swash ring with a wobble pin and one with the drive motor cooperating, non-rotatably connected to the gear shaft Drive pinion.
  • the non-rotatable connection of the hub body and the Drive pinion opposite the gear shaft is used on the hub body and the drive pinion arranged internal spline, which in an external spline the gear shaft engages.
  • The serves as the rotary drive for the tool spindle Output sprocket external spline toothing of the gear shaft, which rotates in a engages gear connected to the tool spindle.
  • the spline gears are manufactured on processing machines whose high Hourly rates negatively affect the manufacturing costs of the gear shaft, the bearing body and the drive pinion. Because of this high manufacturing cost, this can known drilling and / or chiseling device cannot be produced economically.
  • the invention has for its object to provide a drilling and / or chisel device, its striking mechanism and tool spindle drive are simple and easy to assemble as well as being economically producible.
  • the object is achieved in that for actuating the wobble pin an integral countershaft is provided which has a groove for one Swash ring having wobble pin, at least one drive pinion and on both sides of the Groove has one bearing each.
  • the countershaft according to the invention in which the raceway and the drive pinion are in one piece arranged on it is simple in its construction, economical to manufacture and can be installed quickly and safely in the drilling and / or chiseling device.
  • the two Bearing points are spaced apart and act with corresponding ones in the housing of the drilling and / or chiseling device arranged storage areas together.
  • the countershaft has the groove on one, essentially one spherical bearing body forming outer contour.
  • the groove runs inclined to the longitudinal axis of the countershaft and is used to accommodate, for example Balls protruding into another groove on the inside of a swash ring.
  • On the wobble ring is the wobble pin projecting radially from the wobble ring.
  • the first is expediently located at a first, free end of the countershaft Bearing arranged.
  • This freely accessible bearing point can be used in a plain bearing be pressed into a corresponding storage area of the housing.
  • the diameter of the bearing corresponds to the inside diameter of the plain bearing.
  • This first bearing point can be from the opposite of the drilling direction, free end of the countershaft be formed.
  • the drive pinion is arranged between the first bearing point and the raceway. The The drive pinion is thus located in the area of the first, free end of the countershaft.
  • the one transferred from the countershaft to the striking mechanism via the wobble pin Drive movement creates loads that are perpendicular to the longitudinal extension on the Counter shaft act.
  • a good storage or support of the countershaft is achieved by preferably between the second, free end of the countershaft and the groove is arranged the second bearing point.
  • the drive pinion of which preferably has a larger effective diameter has as the output pinion, a tool spindle can be driven in this way that the speed of the tool spindle is lower than the speed of the drive motor.
  • the drilling and chiseling device shown in FIGS. 1 and 2 has a housing 1 a handle 6 in an end region of the housing opposite the drilling direction 1, an operating switch 7 arranged in the handle 6, one from the handle 6 protruding electric cable 8 and one with a tool spindle 23 in connection standing tool holder 9 in an end region of the drilling direction Housing 1 on.
  • the tool holder 9 is a drilling or chisel tool, not shown used.
  • the housing 1 consists of a counter to the drilling direction to the tool holder 9 adjoining gear housing 2 and one to the Gear housing 2 connecting motor housing 3 together.
  • an electric drive motor 4 is arranged, which is connected to the actuation switch 7 can be switched on.
  • the wobble mechanism 25 shown in particular in FIG. 2 is composed of a countershaft 11 with two bearings 19, 20, a drive pinion 10, one on the countershaft 11 arranged groove 15, a wobble ring 13, one on the wobble ring 13 arranged groove 16, a plurality of balls 14 and one arranged on the swash ring 13 Swashpin 12 together.
  • the swash ring 13 is on the balls 14 with respect to the countershaft 11 in the circumferential direction rotatably mounted.
  • the balls 14 partially protrude into the inclined to the longitudinal axis of the countershaft 11, arranged on the outer contour of the countershaft 11, circumferential groove 15, and partially in the on the inner contour of the Swash ring 13 arranged groove 16.
  • the drive pinion 10 acts with a toothing the drive shaft 5 of the drive motor 4 together.
  • free end is the first bearing 19, which is is supported on a first bearing region 17 of the housing 1 via a slide bearing 26.
  • An output pinion is located on a free end of the countershaft 11 facing the drilling direction 21 arranged in a rotatably connected to a tool spindle 23 Gear 22 engages.
  • the second bearing 20 is arranged, which is a ball bearing 27 is supported on a second bearing area 18 of the housing 1.
  • the striking mechanism 28 is composed of a cylinder 29 and an axially displaceable in the cylinder 29 Percussion piston 30 together.
  • the cylinder 29 is in one of the drilling directions opposite end area closed.
  • a movement joint 31 arranged with a pivot pin 32 which is perpendicular to the longitudinal extent of the pivot pin 32 extending bore.
  • the grips into this hole Swash pin 12 of the swash ring 13 a longitudinally displaceable.
  • the cylinder 29 is secured against rotation with the wobble pin 12 coupled.
