avoiding coupling failure considerations in design jaw couplings are considered failsafe because, even if the spider fails, the jaws of the two hubs interlock, allowing continued power transmission. in contrast, an ham coupling with a similar failure mode of its center disc will disengage and not allow continued power transmission. avoiding coupling failure considerations in design jaw couplings are considered failsafe because, even if the spider fails, the jaws of the two hubs interlock, allowing continued power transmission. in contrast, an ham coupling with a similar failure mode of its center disc will disengage and not allow continued power transmission. analysis of common failures and causes of cone crusher 1.cracking sound when breaking ore. main reason: the working mechanism of the cone crusher is composed of a crushing cone with a liner and an adjusting ring. a layer of zinc alloy is cast between the cone of the crushing cone and its liner, and between the liner and the adjusting ring. jaw pain could be sign of serious heart condition symptoms jul 23, 2008 · pain in the jaw or teeth could indicate a heart condition or higher risk for heart attack. learn about this symptom and how it relates to heart health.
