Lubricant for heavy-duty slide bearing

Abstract

A lubricating material for sliding bearings under heavy load conditions, which contains sodium-based grease and 8% to 12% of clean water; or contains sodium-based grease, 1% to 33% of additives and 12% to 30% of clean water water. That is to say, the lubricating material is a water-containing sodium-based lubricating grease containing 8% to 30% of clean water. The invention is a kind of lubricating material which basically has no pollution to the environment, has good lubricating effect, has heat balance effect on friction pairs and has low cost.

Description

Technical field [0001] The invention relates to a lubricating material, in particular to a lubricating material used for a heavy-duty sliding bearing of a thin plate rolling mill. Background technique [0002] In some occasions where rolling bearings are not suitable or too expensive to use, people choose sliding bearings. For example, most of the roll journals in small and medium-sized sheet rolling mills are supported by sliding bearings (specifically, an open sliding bearing with upper and lower bushings). However, this kind of sliding bearing works under heavy load conditions, so the lubrication of this kind of sliding bearing has become a problem that must be solved first. The current solution on the rolling mill is to mix graphite and asphalt together to make a colloidal lubricating block, and then place the lubricating block on the side of the sliding bearing and the roll journal so that the lubricating block is in full contact with the roll journal . During operation, the...

Problems solved by technology

Its main disadvantage is that when making the lubricating block, the asphalt needs to be melted first, and then the graphite can be mixed in; in order to ensure sufficient mixing, sometimes it is necessary to continuously stir

Therefore, the roll journals and their slide bearings still have to be lubricated with pitch graphite lubricating blocks
