| Abstract: | The computation problems of pitches and stresses of the broken-sc-rew locking mechanism with variable pitches are solved by using the finite-element analysis.In accordance with the characteristics of step-by-step vanishing of clearances between gears, and with elastic bound-ary canditions, the successive loading method and the iteration method for treating the boundary conditions are put forward.SAP5 program is used for computation.The comparison between the analysis of numeri-cal example and experimental results show the satisfactory agreement,which proves the reliability of these methods. |
