【Abstract】 The mathematical model of reliability design of sliding bearings of printing cylinder is provided and established.The calculation of anti abrasion(abnormal abrasion and normal abrasion)reliability is proceeded in the sliding bearings of printing cylinder by taking J2108 folio single color offset press for example.The regularity of reliability changes with time,and the method of improving the life of bearings by reforming their material are presented.The results are of practical guiding significance to the design and use of press.更多还原
