Abstract


Heavy-duty electric wheel dump truck with its high efficiency, large volume, the economy is good and become million-ton annual production of more than open pit mine , a large water conservancy construction project the ideal means of transport . Although China has been able to produce heavy-duty electric wheel dump truck, but its rim reducer components rely entirely on foreign companies. The topic for the import of heavy-duty electric wheel dump truck rim ring gear reducer ring gear breakage during use, this problem , the use of its high-performance software ANSYS finite element analysis of the inner ring . Based on the special structure rim reducer , gear train their defaults were highlighted , and the main gear bearing capacity calculations performed . Using 3D modeling software Pro / E, the program (program) to establish a precise parametric model of involute cylindrical gears , simply by modifying the relevant parameters of the model can be obtained to meet the requirements to achieve a parametric model . And using Pro / E secondary development tool Pro / toolkit and C seamless connection , in Pro / E interface developed on the assembly model parameterization procedure assemblies database program , to facilitate different types of fixed axis gear train automatically generated and management. Focus were three ordinary gear meshing with the internal gear ring simultaneously ( three contact pairs ) when the finite element analysis, comparing gear train are set coefficients , three wheel fixed axis relative position changes , internal gear floating offset these three meshing of the gear case stress, comprehensive analysis of the ring gear with the internal splines of the sleeve causes the radial clearance larger floating inner ring offset affecting the internal gear tooth root stress increases the sensitivity factor. Since gear rim special structure, the internal gear is restricted radial mounting dimensions , so a different internal gear tooth width of the finite element analysis, when the tooth width is equal to 230mm, 54mm thickness equal to the rim , wheel edge strength to meet the conditions require .
