相对於主轴中心线的滚子中心位置对椭圆度、稜圆度、及表面光洁度的影响为了研究这个问题,将3616型滚子进行了初磨。工作磨輪的旋转速度V_k=30公尺/秒,鼓輪的倾斜角α=+4°,鼓輪迴转数n_σ=39转/分,磨削深度t=0.07公厘。当滚子中心在主轴由中心线上面的位置被大大地昇高时,椭圆度及稜圆度均减少了;这是由於滚子獲得了更大的稳定位置的缘故。滚子与磨輪及鼓輪相互接触,造成所谓支持稜柱體。在与磨輪相接触的点上,作用有切削力;在与鼓輪相接触的点上,作用有摩擦力。此二力组成一个角。被磨削滚子的中心愈高,则对造成滾子稳定支柱的条件愈有利。
Effect of roller center position relative to the centerline of the spindle on ovality, degree of roundness, and surface finish To study this problem, a 3616 roller was first ground. The working wheel rotation speed V_k = 30 m / s, drum inclination angle α = + 4 °, drum rotation n_σ = 39 rpm, grinding depth t = 0.07 mm. When the position of the roller center is greatly increased above the centerline of the spindle, the ovality and the degree of roundness are reduced; this is because the roller obtains a larger stable position. Rollers and drums come in contact with each other, creating a so-called support prism. In the point of contact with the grinding wheel, the role of cutting force; at the point of contact with the drum, the role of friction. The two forces form a corner. The higher the center of the roller to be ground, the more favorable the conditions for causing the roller to stabilize the strut.
