NEW CONCEPTUAL SOLUTIONS FOR ELASTIC COUPLINGS WITH HIGH CAPABILITY COMPENSATION OF MISALIGNMENTS

Abstract

The paper develops a problem of great interest in power transmissions, very widely applied in practice: the use of elastic couplings having an adequate level of torque transmission and a reasonable axial and angular misalignment capability based on elastic deformations of specific flexible elements. A characterization (discussion) of two elastic couplings characteristic for the area of compensative couplings is offered. An innovative principle of elastic coupling with reinforced flexible elements is proposed. The mechanical strength analysis for both elastic couplings (with spoked metallic membranes and reinforced elastic elements) in the case of existing axial and angular deviations is discussed also. It is revealed that the study of these couplings based on elastic deformations is of great theoretical and practical importance today.
