Abstract

加工螺旋弧面包络蜗杆刀盘、应用现代计算机技术综合齿轮设计软件、蜗杆一蜗轮副设计软件的技术要求,通过2维平面设计编程出蜗轮齿形轨迹图形、转化修形成弧面齿形符合设计要求的各种规格、模数、螺旋角要求的齿形轨迹图形程序,采用数控设备加工出近似于拉齿螺旋弧面蜗轮齿形组合式刀具;通过制齿设备加工、径向以多齿逐一进给啮合导向、消除制齿设备传动链、轴向间隙,高效实现导成、分度及螺旋升角零啮合、加工出螺旋弧面包络蜗杆(3-6)齿包络啮合),可广泛应用于普通设备上、加工单头或多头螺旋弧面包络蜗杆。
The invention discloses a cutter for machining a spiral arc face enveloping worm. The modern computer technology is applied, and the technical requirements of gear design software and worm-gear pair design software are combined, tooth form track graph programs with various specification, module and spiral angle requirements and with worm gear tooth form track graphs and transformed and form-trimmed arc face tooth forms conforming to design requirements are programmed through a two-dimensional plane, and a numerical control device is used for machining a tooth form combined type cutter similar to a gear broaching spiral arc face worm gear tooth shape. Due to machining of a tooth manufacturing device, radial one-by-one feeding, meshing and guiding of multiple teeth and removing of a transmission chain and axial gaps of the tooth manufacturing device, guiding, indexing and lead angle zero meshing are achieved efficiently, spiral arc face enveloping worm (3-6) teeth are machined and are meshed in an enveloping mode, and the cutter can be widely applied to a common device for machining single-head or multi-head spiral arc face enveloping worms.
