Structural Multi-solution Optimization and Dynamics Analysis of The Main Roller Shaft of Bolt

Abstract

In order to Gatling gun's main roller shaft, it shows by using the force analysis. It shows the rotation speed of the main roller shaft is non-constant, it can be determined by the cam curve and the clearance fit between the main roller and the cam curve. The speed of the revolution and position of the main roller shaft was raised and dropped in the core hole. The main roller shaft is sometimes integrated with the bolt movement, but basically, it makes that the main roller only deforms itself, so the main roller shaft is a method for the Gatling cannon. The Gatling cannon needs the main roller shaft more than the Gatling gun. In Gatling cannon, the main roller shaft must be sure to exist. The main roller shaft and bolt body should be two components, not one component. This is the caliber greater than 20mm scheme, and not for the caliber less than 20mm design.
