欣德利球面蜗杆
Examples
- The process has an advanced principle . the involute hourglass worm drive can realize the design machining of gear form and direction , and the internal meshing honing gear has high efficiency . this process has all merits mentioned above , and also has the advantages of quality stability , high productivity for rude and finish machining
该工艺原理先进，它集有利于实现齿形、齿向设计加工的渐开面环面蜗杆传动与高效的内啮合珩齿的优点与一体，对齿轮的粗、精加工都有质量稳定、生产效率高的优点。 - On the condition of “ many - head ” and “ small drive ratio ” ， the plane double enveloping hourglass worm can not settle the problem of undercutting and sharpening simultaneously . it has devoted to a new type hourglass worm _ sphere double enveloping hourglass worm . the coordinate system is established according to the frock . the meshing equation and the tooth equation of worm and gear have been developed and the distribution of contact line on gear tooth is analyzed . to evaluate the meshing quality ， four meshing quality indexes and five original parameters are put forward . through mass programming computing ， the relations between meshing quality and original parameters are derived and depicted by graphs
考虑到平面二次包络环面蜗杆传动在多头小传动比条件下根切与齿顶变尖的矛盾很难同时解决且啮合性能较差，介绍了一种新型环面蜗杆传动? ?球面二次包络环面蜗杆传动.在研究过程中，根据工装建立了坐标系，根据一二包过程的运动关系推得了啮合方程和蜗杆与蜗轮的齿面方程，分析了蜗轮齿面上的接触线分布.为了评价啮合性能，提出了4项性能指标和5项原始参数，通过大量编程计算得到了啮合性能指标与原始参数之间的关系，并以图表直观的表示 - With the increasingly extensive application of the planar enveloping hourglass worm gearing , it becomes more important to rapid detection and high precision of the manufacture error . the surface of the planar enveloping worm gearing is complicate , and current domestic and international examination concerning its form generally is recur to the general three dimension measure apparatus or the special measure apparatus according to " the type of assemble " principle designed
由于平面包络环面蜗杆齿面比较复杂，其齿形、齿距、齿厚各不相等，因而关于它的制造误差检测也比较复杂。目前国内外关于其形面的检测一般是借助于通用三坐标测量机或按“装配式”检测原理（即测量状态与加工状态一致的原理）设计专用量仪进行的，一直没有十分成熟的专门产品问世。
