Abstract

Harmonic drives are power transmitting devices with high torque and precision. They are used in many applications for their advantage of providing high torque ratio and reduced backlash, thereby reducing the power loss in the drive. The primary objective of this project  is to modify the design of the harmonic dives by introducing harmonic teeth instead of existing straight teeth. The harmonic drives were modeled using SolidWorks. Three incremental loads are applied on a tooth of each harmonic drives and the stress developed on the tooth was found out using structural analysis in ANSYS. The results showed that the stress generated on the helical tooth of the flex spline was less compared with that of the stress developed on the straight tooth. There was an increase in the stress developed as the force acting on the tooth increased.
