Definitions

• the present invention relates to a method and a device for journalling an 'around the horizon' (360° traversable) artillery gun.
• the purpose of the present invention is to offer a new method for constructing the traverse journalling for a gun system with a 360° traversable elevating mass.
• the journalling is so designed that it provides a very clean design externally that is self-supporting and designed to accumulate all the forces affecting the gun in an inner turret basket section, both while idle and during firing, which inner section is infinitely rotatable in an outer turret basket section.
• a hallmark of the present invention is thus a new type of turret journalling based on the fact that the complete elevating mass of the gun in question is mounted in a lower inner section in the form of an inner turret basket that has a truncated conical outer shape with its wider section facing upwards towards the gun and journalled for rotation via a ring-shaped slewing ring while the downwards facing lower, narrower section is journalled for rotation via another ring-shaped slewing ring.
• One or both of these turret basket sections that are concentric to each other around a common vertical axis are infinitely rotatable and may, if so desired, be made gas-tight.
• journalling of the inner section is designed so that the forces that affect it during firing are steered inwards towards the common vertical axis of the concentrically arranged inner and outer turret basket sections which is why the transmission of these forces between both the concentric turret basket sections is solely via the above mentioned slewing rings.
• the present invention is thus based on the fact that the forces at work while the gun is idle and during firing are concentrated to the inner turret basket section for immediate transmission to the outer turret basket section via the two concentric slewing rings of which the upper is the one with the larger diameter.
• the outer turret basket section can thus be used directly for mounting in, and attachment to, a vehicle body in an existing armoured vehicle in which the said section may be incorporated as an integral part of the vehicle chassis.
• a pre-condition is, naturally, that the chassis can support the weight of the complete turret construction and also assimilate the recoil forces arising during firing.
• the truncated conical shape of the turret basket sections also to a certain extent enables the design of the gun to be adapted to weapon carriers of various widths by adapting the mounting height/depth of the turret basket sections in the carrier.
• a third variant is that for fixed turret guns, such as for coastal defence or defence of airfields, it is possible to mount the turret basket directly in a pre-constructed concrete foundation or equivalent.
• Figure 1 shows a general illustration of the self-propelled gun vehicle, while Figure 2 shows a cross-section of the gun concept in Figure 1, and
• Figure 3 shows the gun concept in Figure 2 viewed from above, while
• Figure 4 is a smaller scale diagonal projection of the gun concept shown in
• the gun vehicle shown in Figure 1 comp ⁇ ses, in this example, a two-wheel tractor unit 1 that primarily contains the engine and crew space and whose wheels are designated 2 and 3 (the latter is not visible in the figure) and which via an articulated joint 4. which pivots to left and ⁇ ght but is ⁇ gid m other directions, is connected to a four-wheel gun unit 5 with a completely ⁇ gid chassis design and whose mam parts are the individually sprung d ⁇ ve wheels 6-9 (7 and 9 are not visible in the figure) driven by the engine in a freely elective manner, an outer turret basket section 23, and an armoured turret 10 incorporating the artillery gun 11.
• the wheels on the gun unit are also steerable to enhance the turning radius of the vehicle and to enable the large distance between the bogies necessitated by the location of the turret basket sections.
• the number of wheels on the tractor unit and gun unit may be four, six or eight depending on the vehicle selected. Tracked vehicles, of course, are also an option.
• the outer turret basket section is designated 23 as previously stated.
• the trunnion brackets 20 and 21 are preferably fitted with removable clamps for securing the trunnions 18 and 19. The complete gun is thereby easily disassembled forwards-upwards for servicing for example.
• the two turret basket sections concentrically arranged in each other have a mainly truncated conical shape with their larger diameters facing upwards.
• the inner turret basket section 22 is jouraalled for rotation in the outer turret basket section 23 via a large diameter upper slewing ring 24 and a smaller diameter lower slewing ring 25. Both these slewing rings thus enable the inner turret basket section to rotate through 360° in the outer turret basket section. Rotation may well be by means of a conventionally designed cogged slewing ring and an electric motor located in the inner turret basket section.
• the outer turret basket section is constructed sufficiently stably the latter can thus be used as an integral part of the chassis of the vehicle as illustrated in Figure 1, in which the other components are from a larger type of existing vehicle with articulated steering such as the articulated haulers used for forestry work and road and construction work.
• the armoured turret 10 needs to be mounted in the inner turret basket section 22 and the slewing rings 24 and 25 need to be able to assimilate both the axial and radial forces. It would be appropriate for them to be constituted of large ball or roller bearings.
