一、润滑的作用机床上的许多零件,如车床的溜板导轨和床身导轨,轴和轴承套,相啮合的齿轮,丝杠和螺母等等;在开始作相对运动或运动中,它们的相互接触面之间产生摩擦。摩擦不但要消耗动力,而且会使零件表面磨损。还会使零件的温度升高。 First, the role of lubrication Many parts on the machine, such as lathe slide rails and bed rails, shaft and bearing sleeve, the meshing gear, screw and nut, etc .; in the beginning of relative movement or movement, their Friction between the contact surfaces. Friction not only consumes power, but also wear parts surface. It also raises the temperature of the part.
