| Belt conveyor occupies an important position in the development of domesticmaterial transportation, especially in the coal transportation industry, it is one of themost important transportation equipment. Belt conveyor is a machine that usingfrictional force to realize the continuous material transportation, drive roller is theimportant component parts of it, for a long time running, the surface of drive rollerwear and tear seriously, the coefficient of friction between the belt and the roller willreduce, this will result in skid occurred frequently, therefore exploring how toincrease frictional traction on the surface of drive roller is of great significance.In order to improve the transmission capacity of belt conveyor, from theperspective of increasing the friction coefficient of roller surface, this paper is usinga layer of rubber material covering on the surface of roller to increase frictiontraction, and based on the bionic tribology, design new rubber coating structures,Study wear resistance on the roller surface by the impact of these rubber material.This paper analyzes the theory of belt conveyor’s flexible friction drive, andobtains the mechanical characteristics of the surface of the drive roller. Then itanalyzes the reason for skid of the belt conveyor, and puts forward three methods ofincreasing traction of belt conveyor transmission device, which increasing thefriction coefficient is more practical and economical.Take diamond channeled rubber roller as the research object, using finiteelement software analysis to compare the stress and deformation of the ordinary steelsmooth roller with the rubber roller, and analyze the wear characteristics on surfaceof the roller. Based on the bionic non-smooth theory, using the bionic design methodto design several new rubber coating structures, which convex hulls’ structure andsize are different. Then it analyzes the main factors affecting wear resistance ofrubber coating, selects rubber coating’s three factor: material, structure and size, andin ANSYS, contrasts and analyzes finite element analysis results of contact model ofbionic rubber coating and cylinder shell, study the wear resistance effects of variousfactors on the rubber coating.Using the orthogonal experiment design method to seek a better wearability rubber coating’s the whole structure scheme. Take the bionic rubber coating modelas the research object, this paper arranges rubber coating friction performance test ofdifferent parameter combinations under the factors influencing rubber coating(material, structure, and size). Using variance analysis method to analyze the testdata results based on ANSYS, finally it is concluded that the primary and secondaryorder of factors affecting wear resistance of rubber coating, and determined theoptimal parameter combination plan of wear resistance of rubber coating. |
