driving spring การใช้

• The Bendix system places the starter drive pinion on a helical drive spring.
• The lock frame was retracted by recoil action during automatic firing and is forced forward by the driving springs.
• The driving spring then forces the piston rearward, which reverses the action and returns the bolt to battery ."
• The driving spring assemblies held the lock frame against the carrier dog until the carrier was released by carrier catch which was pivoted by the incoming round.
• The recoiling mechanism of the gun included the tube and tube extension, recuperator piston and piston rod, lock frame assembly, driving spring assemblies, and the breechblock assembly.
• As the huge pendulum below the Clock rocks the Chronophage as he steps round the great escapewheel, each backward and forward movement is used by sprag clutches to wind up the drive spring.
• Early M60s also had driving spring guides and operating rods that were too thin and gas pistons that were too narrow behind the piston head ( part of an attempt to save weight ), leading to problems with breakage.
• Changes included increasing the weapon's rate of fire to 1, 100 rounds / min, eliminating the buttstock, adding a spade-type grip to the rear of receiver, moving the main drive spring under the barrel and most importantly  changing the feed system.
• A slight delay in primer function, and the gun reverts to a simple blowback without the benefit of a massive bolt and stiffer driving spring to soften the recoil impact . [ . . . ] The exacting requirements in design and construction of gun and ammunition reduce this type almost to the point of academic interest only ."
