Research and Application of a Thin Oil Internal Circulation Lubrication Drum Gear Coupling
Due to the problems such as frequent breaking of connecting rod,easy damage of supporting bearing,abnormal oil return of oil collecting cover and abnormal wear of the flat head jacket centering ring,the traditional thin oil external circulation lubrication drum gear coupling equipment has high failure rate and unsatisfactory use effect,which seriously affects the normal operation of rolling mill.This paper introduces a thin oil internal circulation drum gear coupling,optimizes some structure,innovates the oil inlet and return circuit,sets up the three-degree-of-freedom sealing device to realize lubrication oil circulation in the shaft body,which improves the lubrication effect of the drum gear tooth surface,reduces the contact wear,improves the running stability of the connecting shaft,and prolongs the service life of the drum gear coupling.
