Abstract

The invention provides an ashless antiwear oil film bearing lubricant composition, which comprises: (A) at least a highly refined mineral oil with high viscosity index; (B) at least an emulsifier; (C) at least an anti-foaming agent; (D) at least an ashless phosphorus-containing antiwear additive; (E) at least an anti-oxidant; and (F) at least a metal passivator. The above lubricant component has excellent demulsibility, filterability, anti-foaming property, air release property, abrasion resistance and oxidation resistance, passes through FAG FE-8 bearing wear experiments, SKFEMCOR bearing corrosion experiments and FLENDER anti-foaming experiments, and is suitable for lubricating various bearings and industrial gears, especially lubricating highspeed wire rod oil film bearings.

Description

(1) Technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition used in an oil film bearing system, and belongs to the technical field of lubricating oil and lubricating oil additives. (2) Background technology [0002] It is inevitable that industrial water will enter the lubrication system during the use of anti-wear oil film bearing oil. Therefore, it is required that the anti-wear type oil film bearing oil not only has good anti-wear and filterability in the presence of water, but also must be able to quickly separate the water in the oil in a static state to ensure the water content in the lubricating oil. Do not exceed the standard. Due to the above special requirements for the use of anti-wear oil film bearing oils, it is difficult for domestic lubricating oil research and development and production institutions to break through the above technical bottlenecks, and anti-wear oil film bearing oils have ...
