在精研凸度圆柱滚子时,鼓形导辊接触角γ_0是一个重要的工艺参数,它对滚子精研时的转动稳定性有较大影响。本文在建立滚子精研的运动及动力学模型的基础上,分析了γ_0对滚子转动特性的影响规律,认为γ_0存在一个临界值γ_(0max),为保证滚子稳定转动,必须满足γ_0<γ_(0max)。
In the study of convex cylindrical rollers, the drum guide roller contact angle γ_0 is an important process parameter, which has a greater impact on the rolling stability of the roller lapping. In this paper, based on the kinematics and dynamics model of roller lapping, the influence of γ_0 on the rolling characteristics of the roller is analyzed. It is considered that γ_0 has a critical value γ_ (0max). To ensure the stable rotation of the roller, γ_0 <γ_ (0max).
