本文分析了摩擦阻力和相互接触作用对凸轮-链轮机构动力学特性的影响。建立了凸轮-链轮接触的动力学模型。选择的结果，该模型的数值模拟的情况下，在接触区有油润滑和无油润滑。已经观察到伴随凸轮-齿盘接触动力学的各种现象，例如，凸轮轴旋转的全局方向的变化、这些旋转的局部振荡、摩擦随凸轮轴纵向振动频率的变化。我们确认，凸轮轴纵向振动幅度的增加会导致挺柱转速的增加，而其降低到较小的值会导致挺柱旋转停止。
In this paper, the influence of friction resistance and mutual contact interaction on dynamical properties of the cam-tappet mechanism is analyzed. A dynamical model of the cam-tappet contact has been developed. Chosen results of numerical simulations of this model are presented for cases with and without oil lubrication in contact zones. Various phenomena accompanying the cam-tappet contact dynamics have been observed, e.g., change of the global direction of tappet rotation, local oscillation of these revolutions, changes of friction in function of frequency of the camshaft longitudinal vibrations. We confirm, that the growing amplitude of camshaft longitudinal vibration causes an increase in the tappet rotational speed, whereas its reducing to small values leads to stopping the tappet rotation.
