Special grease for worm and gear and preparation method thereof

Abstract

The invention relates to a special grease for worm and gear and a preparation method thereof. The grease is prepared by adding an extreme pressure anti-wear agent and antioxidant into high viscosity refined mineral oil as the base oil and a mixed soap as a thickening agent, and adding a special synthetic material. The production process of the special grease for worm and gear is as below: adding the base oil, an organic thickening agent, a tackifier B into a high-speed flow contactor by a predetermined weight proportion; conducting a saponification reaction at 100 DEG C-115 DEG C (simultaneous addition of part of the additive and reactants) for 1-2 hour; refining at the maximum temperature of 190-200 DEG C, and insulating for 60-90 min; transferring the reaction products to an intermediate tank for cyclic shear, and cooling to 120-150 DEG C; homogenizing; then cooling to 80-100 DEG C, adding an inorganic thickening agent, a tackifier A, the antioxidant, and the extreme pressure anti-wear agent; and then degassing, filtering and packaging. The special grease for worm and gear has the advantages of good adhesion, long service life, same life as equipment, good low temperature performance, high load carrying capacity, anti-friction properties and good pumpability.

Description

technical field [0001] The invention relates to the field of special lubricating grease for worm gears, in particular to a special lubricating grease for worm gears and a preparation method thereof. Background technique [0002] For the lubrication of the worm gear of the reducer, lubricating oil was mainly used in the past, and there are several disadvantages: [0003] 1. Due to the high temperature of the working environment, the viscosity of the oil decreases, and it is easy to leak, which not only pollutes the environment, but also causes waste. The worm gear and worm cannot achieve the effect of lubrication and protection, resulting in serious wear and tear of the worm gear, worm, and bearings, and premature scrapping. [0004] 2. The service life of the oil is short. Under the condition of high temperature and water, the oil will quickly emulsify, deteriorate, and spoil, which requires constant replacement of new oil; the cost of use will increase. [0005] In recent ...

Problems solved by technology

[0003] 1. Due to the high temperature of the working environment, the viscosity of the oil decreases, and it is easy to leak, which not only pollutes the environment, but also causes waste. The worm gear and worm cannot achieve the effect of lubrication and protection, resulting in serious wear and tear of the worm gear, worm, and bearings, and premature scrapping

[0004] 2. The service life of the oil is short. Under the condition of high temperature and water, the oil will quickly emulsify, deteriorate, and corrupt, which requires constant replacement of new oil; the cost of use will increase

However, with the development of the reducer industry, higher requirements are put forward for the reduction of worm gears, and the corresponding requirements for the quality of lubricating grease are very high. Meet the long service life of the equipment is not up to the requirements
