Mechanical load analysis and benchmarking of one-way clutches for e-bike drives
An overview of one-way clutches, used design principles and criteria for selection was prepared. The main problem while designing an e-bike drive using a sprag clutch was the assembly tolerances. Therefore, an analysis using the finite element method of two different type of clutches was conducted....

| Summary: | An overview of one-way clutches, used design principles and criteria for selection was prepared. The main problem while designing an e-bike drive using a sprag clutch was the assembly tolerances. Therefore, an analysis using the finite element method of two different type of clutches was conducted. In order to do these analyses, 3D model of sprag clutch and the ratchet and pawl clutch have been created. For each clutch type the calculations of the loads have been made, and used them to run the simulations. Once the simulations have been done, the deformation and the von Mises stress values have been checked to verify if the designs could bear the loads applied. After verifying the models, the materials, which the clutches should be made in order to bear the applied loads, are proposed. On the base of multiple criteria assessment ratchet and pawl clutch was selected as more appropriate |
