Description

7309278-s 2 Uppfinningens uppgift är därför att skaffa en drivgördel, som har de kända fördelarna men även är så utformad, att den kan motstå höga gastryck på projektilkroppen. Denna uppgift löses enligt uppfin- ningen så att projektilen är utformad såsom anges i patentkravets kännetecknande del. ' En utföringsform av uppfinningen beskrives nedan under hänvis- ning till bifogade ritning, som visar ett längdsnitt genom projektilen. 7309278-s 2 The object of the invention is therefore to provide a propulsion belt which has the known advantages but is also designed so that it can withstand high gas pressures on the projectile body. This task is solved according to the invention so that the projectile is designed as stated in the characterizing part of the claim. An embodiment of the invention is described below with reference to the accompanying drawing, which shows a longitudinal section through the projectile.

Drivgördeln 1 är delad i flera segment, som så länge som projektilens icke visade styranordning ännu befinner sig i eldröret genom i axiell riktning verkande medbringare 4 i form av gängor eller spår är fast förbundna med projektilkroppen. Segmenten ar utvändigt sammanhållna av ett ringformigt band 5. Gördelns akterända är väsentligen utformad som en kon 1d med en avsats 1e intill projektilkroppen 2, och en avsats 1f vid periferin, vilka bildar mot projektilen vinkelräta ringytor. På dessa ytor är en tätningsskiva 7a fäst med skruvar 10 i gördeln 1, men den kan dessutom fästas med klister eller fästas enbart med klistret. Vid hopsättning med skruv bör man företrädesvis förstärka fasthållningen genom att lägga en underläggsskiva 11 under skruvskal- larna. Inom uppfinningens ram är det tänkbart att göra skivan 7a och bandet 5 i ett stycke.The drive belt 1 is divided into several segments, which as long as the projector's device (not shown) are still in the barrel by axially moving carriers 4 in the form of threads or grooves are fixedly connected to the projectile body. The segments are externally held together by an annular band 5. The aft end of the belt is substantially formed as a cone 1d with a ledge 1e adjacent the projectile body 2, and a ledge 1f at the periphery, which form perpendicular annular surfaces towards the projectile. On these surfaces a sealing plate 7a is fastened with screws 10 in the belt 1, but it can also be fastened with glue or fastened only with the glue. When assembling with a screw, the holding should preferably be strengthened by placing a washer 11 under the screw shells. Within the scope of the invention, it is conceivable to make the disc 7a and the belt 5 in one piece.

Projektilen arbetar enligt följande. - Det vid avfyringen uppstående gastrycket kan uppdelas i en axial- och en radialkraft. Radialkraften åstadkommer att gördeln 1 hålles fast vid projektilen, varigenom en pålitlig överföring av kraften till projektilen äger rum. gl Alla i dessa handlingar uppenbarade uppgifter och kännemärken, särskilt den visade konstruktiva utformningen förutsättas, i den mån de är nya.i förhållande till teknikens_ståndpunkt, som väsentliga för uppfinningen.-The projectile works as follows. - The gas pressure generated during firing can be divided into an axial and a radial force. The radial force causes the belt 1 to be held to the projectile, whereby a reliable transfer of the force to the projectile takes place. gl All the details and features disclosed in these documents, in particular the constructive design shown, are presupposed, in so far as they are new in relation to the state of the art, as essential to the invention.
