Modification Design and Contact Property Analysis for Profiles of Archimedes Type Sprag Clutch
摘要
Abstract
Contact properties of Archimedes type sprag clutch (including Hertz stress,circumfer—ential stress and total deformation)were analyzed and compared with three-arc type sprag clutch on the basis of different initial inner wedge angle models.To improve the bearing capacity of Archimedes type sprag clutch,modification on sprag profile of Archimedes was conducted by increasing the initial inner wedge angle,and contact properties of clutch were analyzed after modification;The results show that contact stress is reduced and the critical torque is improved when increasing modification co—efficient.Moreover,the maximum modification coefficientμis obtained from self-locking condition a—nalysis.关键词
