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 EP-A-0 038 399 (published on October 28, 1981, prior art according to Art. 54.3 EPC).
- 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 by the influence of friction should be avoided and malfunctions caused by wear, especially at the clinker tip, but also in the housing guide of the control pin, should be prevented.
- a lead brake has been created for the transport gears of a respective feed shaft, in which friction and wear when engaging and disengaging the ratchet wheel no longer have any effects because the pawl by the two lever arms firmly connected to the movements of the Drive pinion engages and 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 pin and its guidance according to EP-A-0 038 399 are not required.
- a particularly favorable constructive design results in accordance with the features of claim 2 in that premature disengagement of the pawl from securing the ratchet wheel is prevented because a lever arm arranged on the pawl upon rotation of the drive pinion by sliding over a longer area of the control cam the pawl disengages the diameter D with a time delay.
- Each control curve 2 on the drive pinion 1 is a lever arm 14 with a sliding surface 16 and, corresponding to the control curve 3, a lever arm 13 with a sliding surface 15 is a pawl 4 with pawls tip 20 assigned.
- 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 offset in the axial direction 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 pawl is in the axial direction of the bearing 18, and in Figure 6, the laterally cranked lever arms are shown with the sliding surfaces 15 and 16 extending parallel to the pawl.
- 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 ratchet 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.
