Toothed Belt Transmissions: Coupling and Angular Stiffness

This lecture covers toothed belt transmissions, focusing on their use as coupling elements and the calculation of angular stiffness. It explains the advantages and disadvantages of toothed belt transmissions, emphasizing their low cost, high speeds, and low resolution. The instructor discusses the importance of prestressing the belt and varying its width for desired transmission stiffness. Additionally, the lecture delves into the calculation of the angular stiffness of a belt transmission, considering the belt as two springs. Practical aspects such as belt preload, mounting plates, and pulley diameters are also explored, highlighting the key factors to optimize the performance of toothed belt transmissions.
