Abstract
A piston pin hole friction and wear test and torque measurement device in power machinery field, comprising a driving system, a torque measurement system, a loading system, a temperature control system, an oil supply system and a central controller. The driving system simulates the oscillation of the connecting rod. The loading system simulates the time-varying cylinder pressure load. The oil supply system and the oil channels of the connecting rod, bushing, and piston pin simulate the oil supply state. The torque measurement system comprises a total friction torque measurement device and a small head bushing hole friction torque measurement device, and measures the friction torque at the piston pin seat hole and the piston pin small head hole in real time. The temperature control system simulates the thermal load. The present application carries out tests based on actual components and realizes real-time measurement of friction torques.
