Nyíróerket

Nyíróerket is a Hungarian term that translates roughly to "shear pin" or "shear bolt." It refers to a type of fastener designed to break or shear under a specific load or torque. This intentional failure mechanism is employed as a safety device or a method of load limitation in various mechanical systems.

The primary function of a nyíróerket is to protect more expensive or critical components from damage caused by overloads. When excessive force is applied, the nyíróerket will shear, interrupting the power transmission or movement and preventing a catastrophic failure. Once the cause of the overload has been identified and rectified, the sheared nyíróerket is replaced, and the system can resume operation.

Examples of where nyíróerket might be found include agricultural machinery, such as PTO (power take-off) shafts on tractors, where they protect the gearbox from sudden shocks or blockages. They can also be used in conveyor systems, pumps, and other equipment where unexpected resistance might occur. The design and material of the nyíróerket are carefully chosen to ensure it shears at the desired load level, providing reliable protection without being so weak that it fails under normal operating conditions. The replacement of a nyíróerket is a common maintenance procedure in many industries.
