Description

2. 459 125 ringformade huvudytans bredd. Det kännetecknade draget enligt uppfinningen är således att huvudytan i princip bara är en smal ring vid ett flera gånger större basparti. Det breda baspartiet förmår även genom sin stora yta att under kort tid ta upp höga temperaturer. Fördelarna med föreliggande uppfinning är särskilt att vid genomgång av eldröret behåller styrbandet sin ursr ungs- form. 2. 459 125 annular width of the main surface. The characterized feature according to the invention is thus that the main surface is in principle only a narrow ring at a several times larger base portion. Due to its large surface area, the wide base section is also able to absorb high temperatures for a short time. The advantages of the present invention are in particular that when passing through the barrel, the guide belt retains its original shape.

Vidare motstår plaststyrbandet med sina utmärkta glidegen- skaper de uppkomna temperaturbelastningarna, emedan endast rela- tivt smala huvudeffekter av eldrörets dragbomprofil skäres in och deformeras. Plaststyrbandet med smalt huvud avleder värmen från deformeringsarbetet vid genomgången av eldröret till den stora foten eller basen. Slutligen innebär den stora foten eller basen ligt förbättrad kraftanpassning till granatkroppen. turavledninqen väsent Tempera- är dessutom viktig då granaten användes i trumeld- vapen, när granaten med plaststyrbandet kommer in i det heta pat- ronlagret.Furthermore, the plastic guide belt with its excellent sliding properties resists the resulting temperature loads, since only relatively narrow main effects of the barrel profile of the barrel are cut in and deformed. The plastic guide band with a narrow head dissipates the heat from the deformation work during the passage of the barrel to the large foot or base. Finally, the large foot or base means improved force adaptation to the grenade body. The temperature is also important when the grenade is used in drum firearms, when the grenade with the plastic guide band enters the hot cartridge bearing.

Enligt ett vidareutförande av uppfinningen kan plaststyrban- dets basparti förankras vid en baktill på granatkroppen anbringad metallisk skål till en drivspegel.According to a further embodiment of the invention, the base portion of the plastic guide band can be anchored to a metallic bowl mounted on the rear of the grenade body to a drive mirror.

Plaststyrmyfiets basparti kan förankras medelst i ringspåret utformade mellansteg eller medelst i ringspåret utformade radiella genomgångsöppningar.The base portion of the plastic guide sleeve can be anchored by means of intermediate steps designed in the ring groove or by means of radial passage openings designed in the ring groove.

Uppfinningen skall nedan närmare beskrivas med hänvisning till bifogad ritning, på vilken fig. 1 är ett snitt genom granatkroppen med st enligt uppfinningen; fig. yrband av plast 2 är ett snitt genom en granatkropp med en drivspegelvägg i form av en metallisk skäl; och fig. 3 är ett temperatur / tid-diagram med jämförelsekurvor för tidigare kända resp. uppfinningsenliga granatkroppar.The invention will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 is a section through the grenade body with st according to the invention; Fig. 2 diaphragm of plastic 2 is a section through a grenade body with a drive mirror wall in the form of a metallic recess; and Fig. 3 is a temperature / time diagram with comparison curves for previously known resp. grenade bodies according to the invention.

I bakpartiet på en granatkropps 1 mantel 2 är ett ringspâr 3 med relativt stor bredd anbringat. I ringspåret 3 är insatt ett styrband 4 av plast och med ett ringspràets bredd motsvarande bas- parti 5. Plaststyrbandets 4 ur ringspàrets 3 radiellt utskjutande huvudyta 6,är utformad väsentligt smalare än baspartiet 5. i exem- plet är baspartiet 5 mer än dubbelt så brett som huvudytan 6. kroppens 1 bakparti är tillslutet medelst en granatslutdel 7.In the rear part of a shell 2 of a grenade body 1, a ring groove 3 with a relatively large width is arranged. Inserted in the annular groove 3 is a guide belt 4 of plastic and with a width corresponding to the base portion of the annular groove 5. The plastic guide belt 4 of the radially projecting main surface 6 of the annular groove 3 is formed substantially narrower than the base portion 5. In the example, the base portion 5 is more than twice as wide as the main surface 6. the rear part of the body 1 is closed by means of a grenade closing part 7.

I fig.In FIG.

Granat- 2 är en drivspegelvägg i form av en metallisk skål 9 av t.ex. aluminium påförd på bakpariet till en granatkropp 8.Garnet-2 is a drive mirror wall in the form of a metallic bowl 9 of e.g. aluminum applied to the back of a garnet body 8.

Claims (4)

3. 459 125 Skälen 9 uppvisar radiellt utskjutande böjda steg 10, vilka för- löper ringformat på skålens 9 yttermantel. Skâlens 9 botten 11 bildar anliggningsyta 12 för det påmonterade plaststyrbandet 13. Även här är styrbandet 13 försett med ett väsentligt bredare bas- parti 14 än huvudytan 15. Diagrammet i fig. 3 visar för jämförelse tvâ kurvor 16, 17 på temperatur / tid-axeln avseende granatkroppar med plaststyr- band enligt uppfinningen och enligt känd teknik. Den nedre kurvan 16 motsvarar den normala förankringen 18 för den nedre granat- halvan 19, medan kurvar 17 visar den uppfinningsenliga förankringen 20 för den övre granathalvan 21. Såsom framgår och som bekräftas genom försök, fungerar granatkroppen med bredare basparti på plast- styrbandet även vid väsentligt högre temperaturer än vad som är fallet vid kända granatkroppar med plaststyrband. Kurvorna visar tydligt temperaturbelastningen i tidsenheter. Patentkrav:3. 459 125 The recesses 9 have radially projecting curved steps 10, which extend annularly on the outer jacket of the bowl 9. The bottom 11 of the shell 9 forms the abutment surface 12 for the mounted plastic guide belt 13. Here too the guide belt 13 is provided with a substantially wider base portion 14 than the main surface 15. The diagram in Fig. 3 shows for comparison two curves 16, 17 on the temperature / time axis. concerning grenade bodies with plastic guide straps according to the invention and according to known technology. The lower curve 16 corresponds to the normal anchorage 18 for the lower grenade half 19, while curves 17 show the inventive anchorage 20 for the upper grenade half 21. As can be seen and confirmed by experiments, the grenade body with a wider base portion on the plastic guide belt also works at significantly higher temperatures than is the case with known grenade bodies with plastic guide bands. The curves clearly show the temperature load in time units. Claims: 1.
