Problems solved by technology

When the gear oil circulates in the system, it cannot quickly break the oil and separate water in the gearbox; the emulsified gear oil will seriously affect the formation of the lubricating oil film, which will cause a certain degree of abrasion, corrosion and wear to the gear. Even severe welding

Abstract

The invention discloses a high water resistance type heavy load industrial gear oil, which comprises the following ingredients in percentage by mass: 90-94% of base oil and 10-6% of other additives. PIO (Poly Internal Olefin) and I-type base oil 500SN are combined to serve as the base oil. The high water resistance type heavy load industrial gear oil has the remarkable advantages that the comprehensive property is good, and the use requirements on various performance indexes are met. The gear oil has good thermal oxidation stability, extreme pressure property, abrasion resistance, anti-rust resistance, foam resistance and outstanding high-temperature demulsibility; the gear face abrasion and scratching or even sintering are effectively reduced, the gear transmission efficiency is improved, and the use requirements of industrial gears in extreme severe rugged environments such as high temperature, high humidity, dust, impact load and strong vibration are met. Products of the industrial gear oil can meet the performance requirements on the viscosity grades N150, N220 and N320 of the GB5903-2011 heavy load industrial gear oil.

Description

technical field [0001] The invention relates to a high water resistance heavy duty industrial gear oil. Background technique [0002] Gears are the main mechanical parts, widely used in mechanical transmission, connection and other mechanisms. Gears are the most important components in a power transmission. The motion and power between any two shafts can be transmitted by using the gear mechanism; at the same time, the gear has the characteristics of large transmission power range and high efficiency, so it is widely used in metallurgy, mining, electric power, hydraulic power, transportation, chemical industry, marine engineering, military industry, Ships and other machinery and equipment. [0003] Industrial gear oil is an important lubricating material to ensure the efficiency of gear transmission and prolong the service life of gears. In the gear mechanism, it mainly plays the role of preventing the wear of the tooth surface, taking away the heat generated by the frict...
