Abstract

The invention belongs to the technical field of self-lubricating material, specifically to a gasket for bearing of end joint of self-lubricating pole and preparation method thereof. The gasket for bearing of end joint of self-lubricating pole is prepared by the following raw materials based on parts by weight: 95-110 parts of terpolymer of co-poly-nylon, nylon MXD-10 and nylon 66, 5-6 parts of molybdenum disulfide, 1.5-4 parts of graphite, 2-4 parts of calcium stearate, 2-3 parts of zinc stearate and 5-6 parts of butyl stearate. The gasket for bearing of end joint of self-lubricating pole, which is prepared by breaking the nylon spherical molecular structure into piece-shaped molecular structure, is advantaged by good toughness, abrasive resistance, corrosion resistance and self-lubrication and high hardness. In addition, the gasket has good mobility. The gasket can ensure uniform injection molding, and suitable gap between the gasket and the inner ring of the bearing of the end joint of self-lubricating pole, and effectively prevent influence from expansion on heating and contraction on cooling.

Description

technical field [0001] The invention relates to the technical field of self-lubricating materials, in particular to a liner for a self-lubricating rod end joint bearing and a preparation method thereof. Background technique [0002] Nylon (polyamide) has a regular molecular structure, high crystallinity and good comprehensive mechanical properties. Its outstanding features are good toughness, wear resistance and self-lubricating properties. It is one of the engineering plastics commonly used in the manufacture of mechanical parts. Traditional Nylon is the gasket material used in self-lubricating rod ends. As a gasket material for self-lubricating rod end joint bearings, nylon has the following disadvantages during use: poor fluidity, long molding cycle, high shrinkage rate, especially during injection molding, due to thermal expansion and contraction, it is easy to cause injection molded nylon Therefore, the coefficient of friction of the self-lubricating rod end joint ...
