Definitions

  • the invention relates to a vibration generator for in particular vibrating stations of, for example, stone molding machines with at least one of a motor Drive that can be rotated, an inner unbalanced mass and an unbalanced mass comprising an outer unbalanced mass, whereby the stepless unbalance adjustment inner unbalanced mass and the outer unbalanced mass relative are rotatable to each other.
  • Known vibration generator for vibrating stations from Stone molding machines have two adjacent, a total of one unbalance body assigned to a vibrating table four unbalanced masses (two inner and two outer unbalanced masses).
  • the four unbalanced masses are stored separately and via four three-phase motors, with regard to their Rotation speed electronically controlled and coupled over it.
  • For relative adjustment an inner unbalance mass against one steep unbalanced spindles are used, a stepless unbalance adjustment and so an amplitude change of the generated directional To be able to make vibrations.
  • Vibration generator of the type mentioned at the beginning create with which the unbalance adjustment safely and precisely is to be carried out, but overall less expensive builds and takes up less space.
  • the vibration generator excels in solving this task of the type mentioned in that the inner unbalanced mass and the outer unbalanced mass each via one of a motorized central drive unit in Drive movements of displaceable endless drive bodies can be driven are and at least one endless drive body Adjusting member is assigned to this endless drive body for the relative rotation of the inner unbalance mass and / or the outer unbalanced mass of one of its drive movements overlaid additional movement granted.
  • the vibration generator according to the invention is only still a motorized central drive unit necessary, the endless drive body, preferably toothed belt, the drives the inner and outer unbalanced mass.
  • the motorized central drive unit two Outputs with drive gears so that the endless drive body without the need for more elaborate electronic control means with exactly matching Speed must be driven.
  • the inner and outer unbalance mass the unbalance adjustment can be carried out by the additional movement of an endless drive body or by opposing additional movements of both endless drive bodies the otherwise in the same direction and with the same Speed rotating inner unbalance mass and outer unbalanced mass rotated relative to each other will.
  • the total parts required including the drive means are conventional Vibration generators significantly reduced, resulting in the total production costs of the vibration generator and thus also one equipped with such a vibration generator Stone molding machine are significantly reduced. Nevertheless, the vibrator works extremely well reliable and is particularly in training, in which both the inner and the outer unbalance mass perform an additional rotary movement, clearly faster with regard to the unbalance to be set regulate.
  • the space requirement of the vibration generator is also extremely positively influenced, so that for example the entire vibration generator with its drive and all necessary parts compact and central below a vibrating table in a vibrating station Stone molding machine is to be installed.
  • the two endless drive means are from this central motor drive unit preferably driven in opposite directions, but via deflection wheels and Overlap or underlap of gears guided in such a way that associated internal and external unbalanced masses rotate in the same direction and adjacent to it Vibration generator arranged or provided imbalance body rotate in opposite directions.
  • the motor Central drive unit now moved in one direction, an endless drive body experiences a direction of its drive movement rectified additional movement, the other drive bodies, however, one to its drive movement direction oppositely oriented additional movement. This automatically leads to a superimposed angle adjustment both the inner and outer unbalance mass.
  • the internal unbalance mass and the are expedient outer unbalance mass as in known vibration generators formed such that the outer unbalanced mass the inner Unbalance mass can spread.
  • the inner unbalance mass with the outer Unbalanced mass combs it is also possible that e.g. the inner unbalance mass with the outer Unbalanced mass combs.
  • the one illustrated schematically in Figs. 1 and 2 Stone molding machine has a base board 1 on which concrete products getting produced.
  • the underlay board 1 lies on a vibrating table 2, whose vertical vibrations are generated by the vibrating stations 3.
  • the Vibrating station 3 with a vibration generator central drive motor 4 that move horizontally is.
  • the drive motor 4 has both Sides on the continuous drive shaft toothed belt wheels, where the two timing belts 4.1 (Endless drive body) over pulleys 4.2 and through Overlap / underlap of the gears performed in this way are that the two timing belts rotate in opposite directions.
  • the Arrows 5 in FIGS. 4 and 5 show this through the Rotation of the motor shaft produced opposite belt movements to generate the vibrations.
  • the toothed belts 4.1 loop around the toothed pulleys 6 so that the four unbalances 7, 8, 9 and 10 despite the opposite Drive movements of the toothed belt 4.1 for the vibrations have the correct direction of rotation.
  • the unbalance 7 and 8 rotate in the same direction, likewise the unbalance 9 and 10. Overall, the directions of rotation of the unbalances are 7 and 8 on the one hand and the unbalances 9 and 10 on the other hand exactly opposite to each other.
  • the displacement of the drive motor 4 can for example done by a gear motor 15, the crank 16 and the connecting rod 17 moves the snowmobile 18.
  • a gear motor 15 can be a gear motor 15, the crank 16 and the connecting rod 17 moves the snowmobile 18.
  • a hydraulic cylinder or a other suitable element can be used.
