| Abstract: | Within the range of small and very small sliding velocities that are typical of applications such as clutch mechanisms, guideways of machine-tools, hydraulic or electric drives for robots, and continuous-indexing mechanisms, the phenomenon of ‘stick-slip’ occurs. By taking into consideration the dependence of kinetic friction force on sliding velocity during the slip period, three critical velocities of movement stability are revealed. One of the important ways for reducing the amplitude of the phenomenon is by designing lubricating grooves of optimum geometry brought about by oil viscosity and surface tension. |
