Breaking pot
The breaker pot (also known as the shear plate ) is a mechanical overload protection device that breaks when a defined force is exceeded and thus protects the machine and workpiece from damage. The operating principle thus corresponds to that of a predetermined breaking point .
The component consists of an inner plate and an outer, axially offset ring. Shear stress results when a force is applied . When the permissible shear stress is exceeded, the plate is axially sheared from the outer ring and pressed into the ring. This is used, for example, in screw presses in the ram joint under the ball socket .
