Contact Analysis for Beveloid Pinion and Rack Considering Axial Clearance Change by Huang Hongxin, Zhao Xingfu, Wang Zengqiang, Yu Guangbin

“…Aiming at the problems that clearance is difficult to modify and operation stability is poor of pinion and rack used in the large machine tool carrier feeding device，the beveloid pinion and rack which can modify clearance axially is proposed.The finite element analysis of the changes of variables such as static transmission error，uniform degree of contact stress，contact force are carried out when considering axial clearance changes.The results show that the influences of axial clearance changes to variables depend on torques directly，the influences when torque is 50 N<inline-formula><alternatives><math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M5"><mo>∙</mo></math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/931788f2-2a25-4c50-a1c8-d8848a15114f-M005.jpg"><?…”

SIMULATION AND EXPERIMENTAL STUDY ON THE STATIC STIFFNESS OF HIGH SPEED MOTORIZED SPINDLE by CUI FangYuan, LI Yan, YU JiaYi, TANG AoFei, LI PengYang, HAN LiLi

“…The static stiffness of the spindle is an important index to evaluate the static characteristics of the motorized spindle,which is essential to ensure the machining accuracy of precision CNC machine tools.Based on the calculation formulas of cutting force under typical conditions and those of radial stiffness of angular contact ball bearing,the axial deformation in front of the spindle,as well as the static stiffness in the specified condition,were obtained through the 3D finite element model of rotor-bearing system.The static stiffness test was performed on the experimental platform.By comparing the simulation results and the experimental results,the validity of the finite element model was indirectly verified.Based on the reliable finite element model,the variations of the static stiffness of the spindle with the preloads of the front and rear bearing groups were gained.…”
