Abstract

The clearance appears in crankshaft pin and connecting rod bushing by manufacturing tolerance or wear of components is the most important factor that influences the dynamic performance and reliability of reciprocating pumps. In this paper, a parametric dynamic model of the crank-connecting rod mechanism of reciprocating pumps considering the crankshaft–bushing clearance is proposed based on the multibody dynamics theory. By simulation, the dynamic response of the mechanism with and without clearance is obtained and discussed. It is observed that the free flight motion between the pin and bushing occurs followed by the impact and rebound phenomenon when the mechanism moves from discharging period into sucking period. The simulation result of the joint force can be used for the strength and stiffness checking of the crankshaft.
