摘　　要：通过分析传力角与动颚摆动角、传力角与机构压力角、机架与肘板摩擦角的关系,推导复摆颚式破碎机主要传递运动部件——肘板作纯滚动无滑动的力学条件。结果表明,传力角与压力角互为余角,即α+δ=90°,肘板机构纯滚动而无滑动的条件是δ≤φ,保证肘板纯滚动而无滑动的条件与肘板的摆角无关。The mechanics condition of pure rolling without sliding of main part of driving movement of pendulum jaw crusher is ascertained by analysis of the relationship of the driving force angle with the pendulum angle of moving jaw and pressure angle of this mechanism, and friction angle between frame and toggle plate. The results show that the driving force angle and the pressure angle are complementary angle each other, i.e. α ＋ δ = 90°, the condition for pure rolling without sliding of toggle plate is δ≤ψ and independent of the pendulum angle of moving jaw.
