Abstract

The present invention provides a worm wheel worm rod lubricating oil composition and a preparation method thereof. The worm wheel worm rod lubricating oil composition comprises 45-75 wt% of poly[alpha]-olefin, 10-45 wt% of oil-soluble polyether, 0.1-5 wt% of an antioxidant, 0.01-0.5 wt% of a metal deactivator, 0.1-5 wt% of a corrosion inhibitor, 0.5-5 wt% of an extreme pressure anti-wear agent, and 0.0005-0.05 wt% of an anti-foaming agent. According to the present invention, the poly[alpha]-olefin and the oil-soluble polyether are adopted as the base oils, the antioxidant, the metal deactivator, the corrosion inhibitor, the extreme pressure anti-wear agent and the anti-foaming agent are adopted as the additives, and the contents of each component are controlled within the content range, such that the worm wheel worm rod lubricating oil composition has the good extreme pressure anti-wear property and the excellent oxidation stability; and the worm wheel worm rod lubricating oil composition further has characteristics of excellent corrosion resistance, excellent rust resistance, excellent shear stability, good oil-water separation property and good anti-foam property.

Description

technical field [0001] The invention belongs to the technical field of lubricating oils, and in particular relates to a worm gear lubricating oil composition and a preparation method thereof. Background technique [0002] Worm Gear Lubricant is a long life semi-fluid gear lubricant. The worm gear mechanism is often used to transmit the motion and power between the two staggered shafts, and has the following characteristics: (1) a large transmission ratio can be obtained, which is more compact than the staggered shaft helical gear mechanism; (2) the meshing teeth of the two wheels There is line contact between the surfaces, and its bearing capacity is much higher than that of the staggered shaft helical gear mechanism; (3) The worm drive is equivalent to a screw drive, which is a multi-tooth meshing drive, so the drive is stable and the noise is low; (4) It is self-locking: When the lead angle of the worm is less than the equivalent friction angle between the meshing gear te...
