Problems solved by technology

Mineral oil is easy to produce sludge except oxidation, pollutes and clogs equipment, also has the characteristics of oiliness, as the worm gear oil composition mentioned in the Chinese patent application CN1727458A, wherein added two kinds of oily agents with a total amount of 1.4% to Reach the corresponding oiliness, which makes the demulsibility of the composition worse (more than 20min), because the oily agent is a surfactant, too much added will affect the demulsibility of the oil
Oxidation stability is an important factor affecting the service life of worm gear oil, but people still do not pay enough attention to its oxidation resistance. Chinese patent application CN102051252A discloses an energy-saving worm gear oil formula, which only contains oily agents, extreme pressure Anti-wear agents, anti-corrosion agents, etc., and no antioxidants are added

preparation example Construction

[0054] The preparation method of the worm gear oil composition provided by the present invention includes: adding one or more polyether oil base oils into a container with stirring, and then adding the above-mentioned B component, C component, D component, E Component, F component, G component and optional H component are stirred at 20-60°C until uniform and transparent.

[0055] The present invention simulates the thermal oxidation stability test of the CRC L-60 gear bench in the laboratory by the oven oxidation experiment. No. steel test piece (45mm×25mm×2mm), then put the beaker in an oven, oxidize at a constant temperature of 150°C for 192h, then take out the steel piece, rinse with petroleum ether, observe the discoloration of the steel piece and the sediment at the bottom of the cup. Grade 0 is unchanged; Grade 1 is slightly discolored; Grade 2 is partially pale white; Grade 3 is mostly pale white; Grade 4 is gray, blue, yellow, or off-white; Grade 5 is partially gray-bl...

Abstract

The invention provides a worm gear oil composition and a preparation method of the worm gear oil composition. The worm gear oil composition comprises a combination of polyether oil base oil, a 2, 2, 4-trialkyl-1, 2-dihydroquinolines antioxidant and a metal passivator. The worm gear oil composition provided by the invention has outstanding oxidation stability, high-temperature detergency, extreme pressure antiwear property, viscosity-temperature performance, anti-foaming performance and high comprehensive performance; and in addition, the preparation method is simple and wide in applicable scope.

Description

technical field [0001] The invention relates to a worm gear oil composition, more precisely, a long-life and clean worm gear oil composition. Background technique [0002] A transmission is one of the types of gear transmission used to transmit power and motion between two axes that are staggered in space. Worm gear transmission has the characteristics of small size, large transmission speed ratio, stable operation, low noise, and large output torque of worm gear, so it has been widely used. Worm gear lubricating oil has a decisive influence on worm gear transmission. It can reduce friction, reduce wear, reduce temperature rise, and improve the efficiency and service life of worm gear transmission. [0003] Due to the large sliding between the tooth surfaces and the relatively long contact time of the teeth in the worm drive, the friction and wear are prominent. Generally, the oil is required to have a higher viscosity, a higher viscosity index, better oiliness, and contain...
