Abstract:

The application of frictionreducing and selfrepairing technology in the diesel locomotives of trains and in the diesel engines of ships shows that the appropriate application of the mentioned technology can result in significant economic efficiency, social efficiency and energyconservation and emissionreducing effect. In the paper, the stateofart of the metal frictionreducing and selfrepairing technology in China and abroad, as well as the necessity to study on the frictionreducing and selfrepairing technology for TBMs, is presented, and the application of frictionreducing and selfrepairing technology in TBMs is studied in terms of application items, application methods and application techniques. The study result shows that the application of the newlydeveloped metal frictionreducing and selfrepairing technology in the lubrication system of the gear box of the main bearing and in the reduction gearbox of the main drive of TBMs is safe, reliable and feasible. 

Key words: equipment management, frictionreducing and selfrepairing technology, TBM, energy conservation and emission reduction
