Definitions

  • the invention relates to a belt feeder of an automatic barrel weapon according to the preamble of claim 1.
  • Such a belt feeder is known from DE-OS 30 15 130.
  • this belt feeder provides a forward brake of the feed shaft gearwheels, which jerkily limits the rotation of the respective feed shaft gearwheel at the end of the belt by engaging the pawl.
  • a control pin which is under spring pressure and is axially displaceable in the housing by the control curve of the drive pinion, is provided.
  • the object of the invention is to avoid the disadvantages mentioned.
  • the impairment of the cadence due to friction influences should be avoided and malfunctions caused by wear, especially at the clinker tip, but also in the housing guide of the control pin.
  • a feed brake has been created for the transport gears of a respective feed shaft, in which friction and wear when the ratchet wheel is engaged and disengaged no longer have any effects because the pawl detects the movements of the by means of the two lever arms firmly connected to it
  • Drive pinion engages or disengages directly into the ratchet gaps of the ratchet wheel by simultaneously retracting and extending the two control cams incorporated on the drive sprocket in a forced sequence without any significant frictional influences.
  • the use of a pen and its guidance according to DE-OS 30 15 130 are not required.
  • a particularly favorable design results in accordance with the features of claim 2 in that a premature disengagement of the pawl is prevented from ensuring the ratchet wheel, because a lever arm arranged on the pawl when the An is turned back pinion disengages the pawl with a time delay by sliding on a longer area of the control cam with the diameter D.
  • Each control curve 2 on the drive pinion 1 is assigned a lever arm 14 with a sliding surface 16 and, in accordance with the control curve 3, a lever arm 13 with a sliding surface 15 and a pawl 4 with a pawl tip 20.
  • the pawls 4 are rotatably supported in their bearing 18 on the fixed bearing shaft 8. Teeth 23 are arranged on the drive pinion 1 on the end face for coupling and uncoupling.
  • Figure 2 shows that lever 13 with sliding surface 15 is engaged in the cam 3, while pawl tip 20 (Fig. 5) of the pawl 4 is disengaged from a pawl surface and lever 14 with sliding surface 16 has left the cam 2.
  • the axially displaceable driving clutch 22 with counter pinion 21 and teeth 24 is mounted within the feed shaft 5.
  • Figure 3 shows the bearing of the shaft 8, which carries the pawls 4 one behind the other, in the housing cover 9, which is covered at the rear by an end plate 10. So that the pawls can be mounted one behind the other on a bearing shaft 8, the ratchet wheels are axially offset on the feed shafts.
  • the lever arms 13 and 14, which alternately engage in the control cams 2 and 3 (FIG. 1), are shorter in the left pawl than in the right one because of the storage arranged one behind the other.
  • FIG. 4 shows the control cams 2 and 3 of the drive pinion 1 necessary for controlling the pawl, curve 2 having a longer sliding area 19 on the circumference with diameter D than curve 3.
  • FIGS. 5 and 6 The pawl 4 with the lever arms 13 and 14 arranged on it can be seen in FIGS. 5 and 6.
  • the drive pinion 1 is thus firmly connected to the feed shaft 5 of the belt conveyor only in such a way that it is carried along in the belt feed direction of rotation, while in the opposite direction due to the arrangement of the two pinions 1, 21 and the clutch 22 by the force of the return spring independently the rotation of the feed shaft 5 is rotatable.
  • the pinion and the blade wheel each have 7 teeth. A cartridge is therefore rotated by 1/7 of 360 ° to feed a cartridge. Of course, a different number of teeth can also be selected.
