齿轮 FZG 试验程序 第 1 部分：油相对磨损承载能力的 FZG 试验方法 A/8,3/90

[中文适用范围]： 本文件规定了一种基于 FZG 四方试验机的测试方法，用于确定润滑油的相对承载能力，该承载能力由齿轮表面损伤（称为擦伤）定义。由于高表面压力和滑动速度导致的高表面温度可能导致润滑膜破裂。此测试方法可用于在规定的温度、高滑动速度和逐步增加的负载条件下评估此类润滑剂的破坏。注意此方法在技术上等同于 ASTM D 5182-19 和 CEC L-07-A-95。 [外文原描述]： This document specifies a test method based on a FZG four-square test machine to determine the relative load-carrying capacity of lubricating oils defined by the gear-surface damage known as scuffing. High surface temperatures due to high surface pressures and sliding velocities can initiate the breakdown of the lubricant films. This test method can be used to assess such lubricant breakdown under defined conditions of temperature, high sliding velocity and stepwise increased load. NOTE This method is technically equivalent to ASTM D 5182-19 and CEC L-07-A-95.
