Flex coupling stress analysis
1 like333 views
A flexible coupling for torque transmission between misaligned shafts is proposed. Finite element stress analysis was used to estimate the life of a 0.2-0.3 inch coupling made of mild alloy steel with a 0.01 inch helical cut to manage shaft misalignment. The analysis applied torque loading and misalignment conditions to determine the stress loading and distortion over the expected range of service life.
