摘要： The performance of a worm assembly seal is improved by (1) the use of a hardened steel worm with a bronze worm gear; (2) the use of a hardened steel worm and a bronze worm gear with a tribological coating on one or both of the worm thread or spiral and the gear teeth; 3) the use of a hardened steel worm and a bronze worm gear with a tribological coating on one or both of the input or output shaft or shaft sleeves; or (4) the use of a hardened steel worm with a bronze worm gear with a tribological coating applied to the worm thread, the gear teeth, the input and output shafts or shaft sleeves, or combinations thereof. In each of the three approaches, the worm, worm gear, and input and output shafts or shaft sleeves can have surface finishing treatments. Additionally, in each of the three approaches, carbon or carbon/nitrogen concentration gradients can be added to the worm. As can be appreciated, each approach builds on the prior approach to further improve seal performance, thereby reducing seal leakage and extending seal life.
摘要翻译：通过（1）使用具有青铜蜗轮的硬化钢蜗杆来改善蜗杆组件密封件的性能; （2）使用硬化钢蜗杆和青铜蜗轮，在蜗杆螺纹或螺旋和齿轮齿之一或两者上具有摩擦学涂层; 3）在输入轴或输出轴或轴套中的一个或两个上使用硬化钢蜗杆和具有摩擦学涂层的青铜蜗轮; 或（4）使用具有青铜蜗轮的硬化钢蜗杆，其具有施加到蜗杆螺纹，齿轮齿，输入轴和输出轴或轴套的摩擦学涂层或其组合。在三种方法中的每种方法中，蜗杆，蜗轮以及输入和输出轴或轴套都可以进行表面处理。另外，在三种方法中的每种方法中，可以将碳或碳/氮浓度梯度加入到蠕虫中。可以理解，每种方法都建立在先前的方法上，以进一步提高密封性能，从而减少密封泄漏并延长密封寿命。

摘要： A process for improving the durability of a differential, where the differential has a pinion shaft and a pinion, the pinion shaft having a surface that contacts the surface of the inner diameter of the pinion. The process comprises bonding to the surface of the pinion shaft or the pinion or both, in the region of the interface between the pinion shaft and pinion, a coating having both a lower coefficient of friction and higher seizure resistance than that of the substance of the pinion shaft when in contact with the substance of the pinion.

摘要： The ability of a worm assembly to resist adhesive and/or abrasive wear, hertzian contact fatigue, and bending fatigue are enhanced by selecting a worm shaft produced from a hardened steel which will maintain the tooth geometry of the worm tooth during service; selecting a worm gear made from a work-hardening metal (such as austenitic steel, a microalloyed steel, wrought steel, compacted metal powder, or cast iron); imparting a finish to the worm and/or worm gear and/or applying a tribological coating containing metal carbides dispersed in an amorphous hydrocarbon or silicon matrix to the worm and/or worm gear.
