The Art of Power in the Millimeter - Decoding the Philosophy of Threaded Connections in Heavy Equipment

In heavy equipment such as excavators and cranes, the torque control of screws directly determines the mechanical reliability. Too tight may cause the thread to break, while too loose may lead to loosening. This article will take the torque curve of the bolts of a certain brand of hydraulic cylinder as an example to analyze how to achieve a "combination of rigidity and flexibility" connection effect through scientific tightening processes.

The torque curve of the bolts of a certain brand of hydraulic cylinder shows that the optimal preload range is 70% to 80% of the yield strength. Through the dynamic torque control system, construction personnel can adjust the tightening parameters in real time to avoid overloading or underloading. In addition, the surface of the bolts is phosphated to reduce the coefficient of friction and ensure the linearity of the torque-preload relationship. This refined control enables heavy equipment to maintain stable performance even under extreme working conditions.
