In order to reach the aim of lightweight designing of the sprocket of aprilia rs 125 sport bike, the topology optimization methodology is introduced to optimize the sprocket. Firstly, the chain transmission part has been optimized and replaced with a new chain, the sprockets are resigned based on the new chain. Then the sprocket model is created in creo. Finally, the sprocket is optimized twice in ansys workbench and the final sprocket model’s total deformation and equivalent stress are checked, the values are all in the safe range. The results show that the optimized sprocket meets the working requirement. The topology optimization design enables sprocket reducing 27% of its mass. The lightweight design has been finished successfully.
