Abstract: Aiming at the self lubricating joint bearing Teflon (PTFE) liner adhesion, the model of GE100ET2RS/PTFE selflubricating spherical plain bearing was established by the ANSYS .The equivalent stress and the contact stress in outer ring, the inner ring, the liner and the curing process ring were obtained. The contact stresstemperature curve was also obtained.The effects of the structure of curing process ring and the curing temperature on the distribution of bearings equivalent stress and contact pressure were predicted.And the curing process ring structure optimization calculation depended the results of the peel strength experiment was carried on. The results indicate that the interference between curing process ring and outer ring and the curing temperature has great influence on the liners contact stress.The curing pressure is linearly proportional to PTFE liner peeling strength.The optimum interference between curing process ring and outer ring is 0.034mm,and the curing process rings optimum thickness is 14.236mm,and the optimized liners mean contact stress is increased form 0.6MPa to 1.3MPa. So the optimization scheme can effectively improve the PTFE liners bonding quality.
