Title The design about simple dual-feeder of machine-gun
Abstract
Dual-feeder technology is widely used in modern middle-caliber gun .It is driven by a unique mechanism, to make one gun select the chains of two kind of bullets. With the development of in-depth principle, to achieve dual-feeder have different methods. But now more mature dual-feeders can be found, they are usually more complex structure, a large weight, only suitable as a vehicle weapons. The author, researching the main dual-feeders for structure, try to simplify institutions and use the traditional machine-gun design theory with the help of computer-aided design and several important parameters of the mechanism are calculated. Several main basis of the completion of the design comes from experience and assumptions, so this article focuses on methods and theories
Keywords： simple dual-feeders CAD traditional feeders
