MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202631123832 A) filed by National Institute Of Technology Jamshedpur on October 15, 2026, for Lightweight Split Pulley System With Adjustable Curvature And Quick Engagement-Disengagement Mechanism For Belt Drives.
Inventors include Tahseen Alam; Ashok Kumar Mandal; and Amit Kumar.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention relates to a hybrid vibration isolation and modular belt-pulley system for mechanical power transmission. The system comprises a belt, a pulley assembly having a curved belt-contacting region configured to provide a relatively large effective curvature with reduced structural mass, a shaft, and a detachable engagement arrangement comprising interengaging mechanical teeth. The engagement arrangement facilitates engagement and disengagement of the pulley assembly with a shaft-mounted member, thereby simplifying installation, maintenance, and replacement. The engagement teeth may be arranged in substantially horizontal or vertical orientations. The system further comprises a hybrid vibration isolation arrangement incorporating passive and active vibration isolation mechanisms configured to attenuate vibrations generated during power transmission. The invention provides a modular pulley configuration intended to reduce unnecessary structural mass, facilitate pulley replacement, and improve vibration isolation and shock-absorbing characteristics in belt-driven mechanical transmission systems.
