摘　　要：钻井泵的动力传递一般都由对心式曲柄连杆机构实现,曲柄连杆机构在高压条件下做变速运动,受力极其复杂。从活塞力、惯性力、摩擦力和力矩等方面对传动机构进行了受力分析,并给出了相关的计算公式。通过动力计算分析,确定了钻井泵动力端机构中的作用力、惯性力及惯性力矩,从而为钻井泵零部件强度、刚度及稳定性校核提供了理论依据。Generally drilling pump＇s power transmission is conducted by crank connecting rod which is working with variable movement under high pressure and has complex force at work. This paper analyzed transmission system＇s force, including piston force, inertia force, friction force, and moment of force. The related equations were provided. The force, inertia force and moment of inertia of drilling pump power end were determined through dynamic mechanics analysis, therefore it provided the theoretic reference for parts intensity, rigidity, and stability check.
