A cross shaft type universal coupling for a front pinch roll of a rolling mill

Abstract

The utility model discloses a kind of cross shaft type universal coupling of front pinch roll of rolling mill, it is related to coupling technical field, the coupling includes flange, spline shaft, spline sleeve, universal joint, two the flange is connected with two shafts by bolt, two the flange end face is uniformly fixed with universal joint, wherein one the universal joint is fixed with spline shaft by bolt, another the universal joint is fixed with spline sleeve by bolt, the spline shaft and spline sleeve inner wall sliding connection are connected.The utility model is provided with end surface tooth on the flange end face, by the intermeshing of end surface tooth and shaft end face, the accurate positioning of flange and shaft is realized, the deviation of centering caused by vibration is greatly reduced;Meanwhile, the meshing structure of end surface tooth enhances the stability of torque transmission, reduces component wear, improves rolling mill operating stability, prolongs the overall service life of equipment.
