齿轮 FZG 试验程序 第 3 部分：半流体齿轮润滑脂相对磨损承载能力和磨损特性的 FZG 试验方法 A/2,8/50

[中文适用范围]： 本文件规定了一种基于 FZG 四方试验机的试验方法，用于确定半流体齿轮润滑脂的相对承载能力，该承载能力由齿轮表面损伤（称为擦伤）定义。此方法可用于评估 NLGI 等级 0 至 000 的半流体齿轮润滑脂的擦伤承载能力潜力，通常用于封闭式齿轮传动的高应力齿轮。它只能应用于在 FZG 试验机的测试齿轮箱中提供足够润滑剂流量的润滑脂。注意：该测试方法在技术上等同于 DIN Fachbericht 74。 [外文原描述]： This document specifies a test method based on a FZG four-square test machine for determining the relative load-carrying capacity of semi-fluid gear greases defined by the gear surface damage known as scuffing. This method is useful for evaluating the scuffing load capacity potential of semi-fluid gear greases of NLGI classes 0 to 000, typically used with highly stressed gearing for enclosed gear drives. It can only be applied to greases giving a sufficient lubricant flow in the test gear box of the FZG test machine. NOTE The test method is technically equivalent to DIN Fachbericht 74.
