摘要: 车齿加工是一种适用于内齿、多联齿结构的高效高精展成加工方法,伴随新能源汽车的发展具有强大的市场竞争力。车齿刀作为车齿加工的重要工具之一,其结构参数直接决定刀具的切削性能与服役寿命。当前刀具的优化设计主要围绕刀齿前刀面以及螺旋角等结构参数基于传统齿轮刀具设计经验与有限元仿真分析开展。然而,车齿刀/工件的节圆尺寸直接决定刀齿切削刃与工件齿槽的具体啮合切削状态,对车齿刀的服役寿命产生影响。为此,以通用的圆柱型车齿刀为对象,采用切削微刃的分析方法对刀具/工件节圆尺寸对刀齿切削性能的影响从瞬时前角、非变形切削厚度、切削服役周期角度进行综合分析,为车齿刀的刀具寿命优化设计从节圆选择角度提供指导。

Abstract: Power skiving is a generating machining method suit to internal and multi-link gears with high efficiency and precision, which exhibits powerful market competitiveness with comply the development of new energy vehicles. As one important component of power skiving, the structural parameters of power skiving tool directly determines its cutting performance and work life. Nowadays, the optimization of skiving tools is focus on the teeth geometries like rake angle, oblique angle, and helix angle with combining traditional experience of gear cutting tools and finite element method based simulations. However, the pitch circle sizes of gear and skiving tool directly decide their meshing condition and produce importance effects on working life of cutting tools. Henceforth, taking the general cylindrical power skiving tool as research object, the influence of pitch circle size on working performance of cutting tool is analyzed by element cutting tool (ECT) method through evaluating the instantaneous rake angle and non-deform chip thickness and the cutting engaging period comprehensively, providing guidance of pitch circle size selection for power skiving tool optimal design of tool life.

Key words: power skiving, pitch circle size, optimization, ECT, cutting performance, tool life
