Rotary Looper roller circle distribution of bending moment and bending stress

a, 71.0MPa, 75.7MPa, stress amplitude were 81.75MPa, 62.6MPa, 57.0MPa, the stress amplitude increases with the bearing angle is reduced. However, with the bearing angle increases, to 180 from the supporting position. The stress amplitude increased significantly, leading to rolling circle between the two support locations increases the amount of fatigue damage, thus increasing the rolling ring bearing angle does not necessarily make a turn in the reduction of fatigue damage. Moreover, the R = Q / (2cosa) (R, said wheel rolling ring on the pressure) that, as a increases, rolling circle increases the pressure on the wheel. Wheel and axle care will also increase the amount of fatigue damage. To improve the support system 4, 2006 Lei Xianming. Xiao Yougang: looper roll rotary circle distribution of bending moment and bending stress. 23. Performance and prolong its life support system should be to minimize the amount of each component based on fatigue damage. So that all components of a considerable amount of fatigue damage. To do this,[link widoczny dla zalogowanych], should be supported through the optimization to find the best angle. Space is limited, rolling ring bearing angle optimization is not discussed here. Jing Zhou Qiang Lane l directly to the location. (') Figure 3, when the rolling ring bearing a fixed angle of the bending stress distribution curve of Fig. 3Bendingstressdistributionoftyreinc & seoffixedsupportingangle4 conclusion rolling ring bending stress occurs in a turn of six alternating towel. New Books amplitude alternating with the increase of bearing load, this cyclical alternating bending stress of constantly making rolling ring weaknesses in the strength of fatigue cracks. When the rolling ring bearing angle 2O. ~ 4O, the rolling ring the amount of stress amplitude with the support - hire static circumferential position (.) Figure 4, when the rolling ring bearing load for a fixed bending stress distribution curve Fig. 4Bendingstressdistributionoftyreincaseoffixedsupportingloads reduced bearing angle increases. However, with the bearing angle increases, rolling circle between the two bearing locations the stress amplitude increased. Rolling ring bearing lead position in both the amount of fatigue damage between the increase, and therefore 2O. 40. Between, there should be one of the best rolling ring bearing angle, the rolling store of the overall fatigue performance of the best.
