Abstract

The invention relates to the technical field of coal mining, and in particular relates to a lurking type composite solid lubrication cutting tooth component of a coal cutter and a lurking type composite solid lubrication cutting tooth component method. The component comprises a cutter tooth, a cutter tooth sleeve and a cutter tooth base, wherein the upper end of the cutter tooth is a tapered body; the lower end of the cutter tooth is formed into a cutter tooth handle by a cylindrical body; the cutter tooth sleeve is sleeved at a cutter tooth handle end of the cutter tooth; the cutter tooth sleeve is located and assembled inside the cutter tooth base; and a gap coaxial body is formed by the cutter tooth, the cutter tooth sleeve and the cutter tooth base. The component is characterized in that at least one gap surface of the cutter tooth and the cutter tooth sleeve and a gap surface of the cutter tooth sleeve and the cutter tooth base are provided with lurking pits; and a waterproof, dustproof and long-acting composite solid lubricant special for a GR cutter tooth is filled into the gap between the cutter tooth and the cutter tooth sleeve and inside the lurking pits. The invention provides the lurking type composite solid lubrication cutting tooth component of the coal cutter and the lurking type composite solid lubrication cutting tooth component method, so that the problems that the parts between the cutter tooth and the cutter tooth sleeve and between the cutter tooth sleeve and the cutter tooth base are severely abraded in the prior art are solved, and the service lives are short.

Description

technical field [0001] The invention relates to the technical field of shearers, in particular to a latent composite solid lubricating pick assembly and method for shearers. Background technique [0002] The coal shearer is a large and complex system that integrates machinery, electricity and hydraulics. The working environment is harsh. If it fails, it will lead to the interruption of the entire coal mining work and cause huge economic losses. With the development of the coal industry, coal mining With more and more functions of the machine, its own structure and composition are more and more complicated, so the reasons for the failure are also complicated. [0003] Shearer picks are involved in all coal mine or rock geological structure excavation processes. The pick is one of the vulnerable parts in coal mining and roadway excavation machinery, and it is the main tool for falling coal and crushing coal. Its performance directly affects the production capacity, power cons...
