Problems solved by technology

First of all, the choice of viscosity should be appropriate: the viscosity of the oil is increased, and it is easy to form an oil film, but the viscosity of the oil is too high, which increases energy consumption, is not conducive to heat dissipation, and is easy to increase the temperature of the bearing pad; the extreme pressure performance of the oil is improved, and the bearing capacity of the bearing pad is increased.

Abstract

Compared with the prior art, the invention provides a lubricating oil composition for a supporting roller large bearing shell of a rotary kiln. The composition comprises the following components in percentages by mass: 5-10% of poly alpha-olefine, 65-79% of brightening oil, 15-25% of a thickener, 0.1-5.0% of an anti-oxidant, 0.01-0.5% of a metal deactivator, 0.1-5.0% of a corrosion inhibitor, 0.5-5.0% of an anti-wear reagent at extreme pressure, and 0.0005-0.05% of anti-foaming agent. The lubricating oil composition for the supporting roller large bearing shell of the rotary kiln has the performances of good abrasion resistance, oxidation resistance, emulsion resistance, corrosion resistance, extreme pressure resistance, high temperature resistance, etc. The lubricating oil composition has a high viscosity coefficient index, so that an oil film of a certain thickness can be formed during normal working of the supporting roller bearing shell, direct contact friction between a supporting roller bearing and a shell is avoided, the supporting roller bearing and the lining shell are effectively protected, and the probability of high temperature at the supporting roller bearing shell is reduced.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a lubricating oil composition for a rotary kiln support wheel and a large tile and a preparation method thereof. Background technique [0002] Rotary kiln equipment is the key equipment in the production process of cement enterprises, known as the "heart" of cement plants. As the supporting point of the rotary kiln, the supporting roller bears three major loads: heat load, material load and kiln self-weight. Due to the relatively poor working conditions of the rotary kiln supporting wheel bearing bush, such as high ambient temperature and heavy load, it is easy to be mixed with dust and water. If the bearing pad of the supporting wheel of the rotary kiln is poorly lubricated, it will cause heating of the bearing pad, wire drawing (the wire drawing is a serious damage to the shaft surface to form streaks), clinging and even overturning of the bearing pad, whic...
