摘要: 本文创造了一种逼近加工法。金刚笔仅作很简单的运动,就能将砂轮修成各种曲线形状。采用最优化方法,在计算机上逼近工作曲线。当把锥面砂轮磨齿机的金刚笔移位后,只作一个直线运动,就可将砂轮修成双曲线,为磨制修形齿轮提供了一种新方法。在成形磨齿时,金刚笔仅作一个旋转运动即可将砂轮修成扁圆曲线,它与渐开线仅差几微米,从而可代替渐开线。此外,还可采用较小基圆产生的渐开线逼进齿轮渐开线,使修整器结构大为简化,从而创造出两种新的渐开线成形砂轮修整器。为高效、经济的大众化磨齿工艺开辟了新前景。

Abstract: This paper presents a new approximate machining method. The diamond moves very simply, but the grind wheel can be dressed into various curves. It is approximate to the required curve by means of optimization and with the help of a computer. On a conic grind wheel grinder, the grand whee can be dressed into hyperbolical curves with setting the diamond a certain displacement and performing only a straightline movement. It provides a new kind of grinding method of modified gears. For involute gear grinding, a dresser, whose diamond can true, a piece of degenerate circle on the grind wheel, moving along a circular arc only is developed now. The error between the curve and desired involute curve is limited to the degree of μm. Besides, also by using a piece of involute curve produced by a smaller base circle disk to replace a desired involute curve, in this paper two new formed gear grinding methods of involute gears are presented, and a new prospect of machining formed gear grinding high efficiently and more economically is shown as well.
