Definitions

  • the invention relates to a device (according to the preamble of claim 1) for driving a moving grate cooler.
  • the construction of the drive is such that a variable-speed electric motor via a gear and a chain drive sets a heavy eccentric shaft in rotary motion, which reciprocates the grating axis of the moving grate with two connecting rods.
  • the force is branched on the high torque side in the crankshaft, which requires a high level of design and manufacturing effort.
  • the invention is therefore based on the object of designing a device of the type required in the preamble of claim 1 in such a way that the construction and manufacturing outlay is substantially reduced.
  • the power split on the Low-torque side is provided between the electric motor and the reduction gear, the heavy and expensive eccentric shaft that was previously required for the power branching on the high-torque side is eliminated.
  • the device for driving a moving grate cooler shown in FIG. 1 contains a speed-controllable electric motor 1, preferably a three-phase standard motor with frequency converter 2 and external fan 3.
  • the reduction gear system is formed by two standard slip-on gear 4, 5, the input side via a thin shaft 6 (in a protective tube 7) and torsionally rigid elastic couplings 8,9, z. B. membrane couplings are interconnected.
  • a shaft 10 or 11 with turned crank pin is inserted into the output-side bushes of the two slip-on gear 4 and 5.
  • the shafts 10, 11 drive push rods 12, 13 which are connected to a drive axle 14 which is firmly clamped in a swing frame 15.
  • the oscillating frame 15 is guided relative to the cooler housing 18 by means of guide rollers 16, 17 during its lifting movement (stroke s).
  • the power split on the low-torque side is thus provided between the electric motor 1 and the reduction gear system formed by the slip-on gears 4 and 5.
  • a coupling half of the coupling 9 is fastened on the shaft 6 by means of a shrink disk.
  • the shaft 6 is expediently divided.
  • Fig. 2 illustrates an embodiment in which the shaft 6 ⁇ is simply divided, the two shaft parts 6 ⁇ a, 6 ⁇ b are connected to one another via a torsionally rigid coupling 19.
  • a bearing 20 is generally required for the shaft 6 ⁇ .
  • the protective tube 7 ⁇ is designed so that it also forms a protective box for the coupling 19 and the bearing 20.
  • normal spur gears are shown in the variant of FIG. 2 instead of the slip-on gear.
  • the shaft 6 ⁇ is divided into two places.
  • the three-part connecting shaft therefore consists of the shaft parts 6 ⁇ a, 6 ⁇ b and 6 ⁇ c, which ver ver via couplings 21, 22 are bound.
  • Two bearings 23, 24 serve to support the shaft 6 ⁇ .
  • the protective tube 7 ⁇ forms protective boxes for the couplings 21, 22 and the bearings 23, 24.
  • Another variant not shown in the drawing, consists in the use of a through shaft guided in three bearings for power branching.
  • the push rods 12, 13 can be made in one or more parts in all embodiments.
  • the bearing heads can already be mounted in the workshop on the crank pins of the shafts 10, 11.
  • the slip-on gear 4 and 5 are preferably designed as multi-stage spur gear and provided with torque supports 25, 26.
  • a further clutch 27 is present between the electric motor 1 and the shaft 6.
