摘要： A method for manufacturing a bevel gear member, comprises the steps of providing a bevel gear blank having a gearhead, forming gear teeth on the gearhead of the bevel gear blank by simultaneously cutting gear tooth top land, gear tooth side profile and a bottom land to form an unfinished bevel gear member using a face hobbing process, and machining at least one selected surface of the unfinished bevel gear member using the top lands of said gear teeth as a datum for centering the unfinished bevel gear member, thus forming a finished product. The method is applicable for manufacturing the bevel gear member both with shaft axially extending from the gearhead and without the shaft. The bevel gear members manufactured with this method exhibit reduced runout and require simpler, less expensive tooling.

摘要： This invention is directed to a method of using a two spindle Hurth-Module multi-spindle (or similar) cutting machine to accomplish face hobbing of hypoid and spiral bevel gear sets. A first cutter mounted on a first spindle would rough cut the gears and a second cutter mounted on a second spindle would finish the gears with both cutters using a face hobbing process. According to this process, multiple cutters are used for a single gear, but on a single machine, thereby reducing cutter wear, increasing cutter life, and raising production output of the multi-spindle machine by utilizing both spindles. In one embodiment, a fine pitch cutter is used to create the initial rough-cut of the gear, and a second coarse pitch cutter is used to create the finish cut of the gear.
摘要翻译： 本发明涉及一种使用双主轴Hurth-Module多轴（或类似）切割机来实现准双曲面和螺旋锥齿轮组的滚齿的方法。 安装在第一主轴上的第一个切割刀将粗略地切割齿轮，并且安装在第二主轴上的第二个切割器将利用两个切割器使用面滚齿工艺完成齿轮。 根据该方法，在单个齿轮上使用多个切割器，但是在单个机器上，通过利用两个主轴来减少刀具磨损，提高刀具寿命，并提高多主轴机床的生产输出。 在一个实施例中，使用细间距切割器来产生齿轮的初始粗切割，并且使用第二粗桨距切割器来产生齿轮的精切。

摘要： Induction hardening of heat treated gear teeth which includes the steps of rough and finish cutting the gear teeth, or alternatively cutting the gear teeth to their final configuration utilizing a one cut method, carburizing the gear and in particular, the gear teeth, slow cooling, or alternatively drawing back the gear so the gear teeth are not hard, and induction hardening the gear teeth heating only the surface of the gear teeth. This results in improved strength for the gear teeth as a result of increased residual compressive stresses therein. Induction heating of only the surface of the gear teeth results in an relatively low case depth in the root of the gear teeth. Since the residual compressive stresses increase as the case depth decreases, the fatigue life of such a gear will be improved as compared to gears produced using known prior art methods which utilize the case depth from the carburizing process which results in a relatively deeper case and, therefore, lower residual compressive stresses in the gear teeth and a less than desirable fatigue life.
摘要翻译： 热处理齿轮齿的感应硬化，其包括粗齿轮和切削齿轮齿的步骤，或者使用一种切割方法将齿轮齿切割成其最终结构，对齿轮进行渗碳，特别是齿轮齿缓慢冷却， 或者替代地将齿轮拉回，使得齿轮齿不硬，并且感应淬火齿轮齿加热齿轮齿的表面。 这导致齿轮齿的强度由于其中的残余压应力增加而增加。 只有齿轮齿表面的感应加热导致齿轮齿根部的相对低的深度。 由于残余压应力随壳深度的减小而增加，与使用已知现有技术方法制造的齿轮相比，这种齿轮的疲劳寿命将会得到改善，这些现有技术方法利用渗碳过程的情况深度，这导致了相对较深的情况， 因此齿轮齿中的较低的残余压应力和较不理想的疲劳寿命。
