摘要: 基于弧齿锥齿轮的数控加工原理,根据产形轮和工件齿轮之间的展成运动,建立了可用于确定数控加工相关参数的弧齿锥齿轮齿面的数控展成数学模型,并论述了切齿加工需要满足的接触条件,在此,基础上提出弧齿锥齿轮数控加工的轨迹规划方法,进而将该方法应用于自主研制的弧齿锥齿轮数控锐齿机中.对所提出的展成模型和轨迹规划方法的应用实例研究表明,该轨迹规划方法切实可行、有效,可用于弧齿锥齿轮的数控切齿加工控制.

Abstract:

On the basis of the principle of NC machining for the spiral bevel gear and according to the generating motion between the generating gear and the work gear , a mathematical model of the generating motion of the spiral bevel gear tooth surface is proposed to determine the parameters of NC machining. The contact conditions of the gear cutting are then discussed , and the trajectory planning method of the spiral bevel gear in NC machining is presented and implemented to control the gear cutting on the self-developed NC milling machine for the spiral bevel gear. Experimental results show that the proposed trajectory planning method is feasible and effective in the control of NC machining for the spiral bevel gear.
