商业军事用途用汽车齿轮脂

[中文适用范围]： 本标准涵盖的齿轮润滑油超过美国石油学会（API）服务分类API GL-5，适用于高速度/冲击载荷和低速度/高扭矩条件下的双曲线型汽车齿轮装置。这些润滑油可能适用于其他齿轮应用，其中轴的相对位置和齿轮齿面接触类型涉及大量滑动接触。此类应用通常需要极压（EP）添加剂，以防止材料在负载齿轮齿面上的粘附和随后撕裂。这些润滑油不适用于蜗轮润滑。 附录A是本标准的强制性部分。附录A中包含的信息旨在证明符合本标准的要求，并列入由润滑油审查研究所（LRI）管理的合格产品清单（QPL）。附录A总结了关键资格要求。完整的资格要求和程序清单可以在性能审查研究所（PRI）网站www.p-r-i.org上的计划文件（PD4000）中找到，齿轮润滑油审查计划。 [外文原描述]： he gear lubricants covered by this standard exceed American Petroleum Institute (API) Service Classification API GL-5 and are intended for automotive units with the primary drive hypoid gears, operating under conditions of high-speed/shock load and low-speed/high-torque. These lubricants may be appropriate for other gear applications where the position of the shafts relative to each other and the type of gear flank contact involve a large percentage of sliding contact. Such applications typically require extreme pressure (EP) additives to prevent the adhesion and subsequent tearing away of material from the loaded gear flanks. These lubricants are not appropriate for the lubrication of worm gears.The information contained within is intended for the demonstration of compliance with the requirements of this standard and for listing on the Qualified Products List (QPL) administered by the Lubricant Review Institute (LRI). A complete listing of qualification submission requirements and procedures can be found in the Program Document PD4000, available on the Performance Review Institute (PRI) website, https://www.p-r-i.org/qpl/lubricant-review-institute.
