Serpentine spring coupling

as a flexible coupling is widely used in general machinery occasions.A novel serpentine spring coupling-the drum serpentine spring coupling is presented.Firstly

the mechanics modeling of the serpentine spring is built

and the statics analysis of the drum serpentine spring coupling is carried out by using the finite element simulation software-ANSYS 12.0Workbench.The results show that the maximum stress value of the drum serpentine spring coupling is smaller than of the latest arc-shaped serpentine spring coupling by the results of static analysis.Finally

the torsional stiffness impact factors of the drum serpentine spring coupling are attained by the torsional stiffness theoretical analysis.
