Problems solved by technology

Although lubricating grease has a variety of excellent characteristics, it is widely used in the transmission and sliding parts of various heavy-duty machinery. Ordinary lubricating grease can play a good anti-wear effect under normal working conditions, but under heavy load, high temperature, high speed, Under special conditions such as corrosive media, the performance will deteriorate sharply, and further improvement is needed

Embodiment Construction

[0021] This embodiment includes 15 kinds of composite greases for heavy-duty bearings composed of different weight percentages of lithium-based grease, microcarbon spheres, and nanoparticles, respectively labeled 1#, 2#...15#, each The weight percentage of lithium-based grease corresponding to the heavy-duty bearing composite grease, the total weight percentage of microcarbon spheres and nanoparticles, and the weight ratio of microcarbon spheres and nanoparticles are shown in Table 1 below.

[0022]

[0023] The nanoparticles are any one of nano molybdenum disulfide, nano aluminum oxide, nano zinc oxide, nano magnesium oxide, nano tungsten disulfide, nano calcium sulfate or any combination thereof, and the diameter of the micro carbon sphere is 400-1500nm. The microcarbon spheres are prepared by hydrothermal method using glucose as raw material. The preparation method is as follows: 6.3-12.6 parts by weight of glucose powder is weighed, dissolved in 50-100 parts by weight of...

Abstract

The invention relates to the field of lubricating grease, in particular to composite lubricating grease for a heavy load bearing and a preparation method thereof. The composite lubricating grease is prepared from the following ingredients in percentage by weight: 99.2 to 99.8 percent of lithium-based lubricating grease and 0.2 to 0.8 percent of micro carbon spheres and nanometer particles. The micro carbon spheres and nanometer particles are uniformly distributed in the lithium-based lubricating grease by using ethanol as carriers. Compared with the existing ordinary lithium-based lubricating grease, the composite lubricating grease prepared after the ethanol evaporation has the advantage that the improvement is realized in aspects of friction heating, friction mark area and the like.

Description

technical field [0001] The invention relates to the field of lubricating grease, in particular to a composite lubricating grease for heavy-duty bearings and a preparation method thereof. Background technique [0002] Bearings are the basic components of large-scale equipment, reflecting the country's manufacturing capacity and manufacturing level, and are an important basic guarantee for major equipment. In addition to factors such as reasonable design, high-performance materials and high-precision processing, manufacturing and installation, the quality of rolling bearings also plays a vital role in the lubricant used. [0003] Grease is a semi-solid or semi-fluid product, a dispersion system formed by thickening base oil with a thickener, and has unique rheological properties. Although lubricating grease has a variety of excellent characteristics, it is widely used in the transmission and sliding parts of various heavy-duty machinery. Ordinary lubricating grease can play a...
