An oil-supply system in liquid lubrication system was designed based on harmonic prin-ciple.The basic structure and oil- supply mechanism were analyzed.The elastomer was one of the main parts.The deformation and particle vibration of the elastomer were as the key factors for oil supplying.The theoretical modes were founded on deformation curve and particle vibration trail of the elastomer.The elastomeric deformation was calculated and analyzed utilizing the finite element soft-ware.And the simulation analysis was done for the oil flowing from storage chamber to friction sur-faces.The calculation results show that：the radial （bending）deformation of elastomer is emerged under the working load;and the particle vibration is occurred along the radial and circumference direc-tions;the deformation and vibration make the oil flow to friction surfaces from the oil cavity through holes.So the oil supply mode in view of the harmonic principle can be achieved.The effectiveness of this oil supply mode was verified.
