Title 30 mm automatic gun bursts of 3 for Ramming Mechanism Design

Abstract The topic of this paper is 30 mm3 repeating a mle design, specific design requirements for lost play is one of the institutions。 This topic to the project design as the research background, in combination with professional theoretical knowledge and practical experience, on the basis of design a new type of chain for losing play system, principle analysis was carried out on the new type for lost play mechanism and the structure design and in the 3 d software set up 3 d model, and the strength analysis was carried out on the main structure parts, guarantee the design feasibility。 

This paper for the lost play mechanism design in the current development status and introduced some, and on the principle and logic analysis。 On the analysis of the new type of 30 mm3 series automatic chariot gun, on the basis of working principle, design to adapt to the new 30 mm3 series automatic vehicles for transport agencies such as structure。 Eventually show that the proposed for lost play device can ensure the rapidness and drug loading, play for the research of new artillery for losing institutions accumulated some experience and advice。

Keywords: Mechanical design; automatic gun; for ramming apparatus; dynamic analysis
