MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621037583 A) filed by Walchand College Of Engineering; Mr. Amol Vasant Walvekar; and Prof. Dr. Sagar Ulhas Sapkal, Sangli, Maharashtra, on March 27, for 'two-shaft multistage gearbox with bearing-mounted integrated gear-pinion pairs eliminating intermediate shafts.'
Inventor(s) include Mr. Amol Vasant Walvekar; and Prof. Dr. Sagar Ulhas Sapkal.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "Two-Shaft Multistage Gearbox with Bearing-Mounted Integrated Gear- Pinion Pairs Eliminating Intermediate Shafts This invention describes a compact multistage gearbox comprising only two parallel shafts-an input shaft and an output shaft-configured to achieve multiple odd-numbered speed reduction stages without employing intermediate shafts. The system utilizes integrated gear-pinion pairs mounted on bearings, allowing relative rotation with respect to the supporting shaft without torque transmission. Only the input pinion is positively coupled to the input shaft, and only the output gear is positively coupled to the output shaft, while intermediate gear-pinion pairs perform sequential speed reduction and torque amplification. The gearbox significantly reduces size, weight, manufacturing tolerance requirements, and alignment complexity compared to conventional multistage gearboxes. The arrangement is scalable to any odd number of reduction stages such as three, five, seven, or more, making it suitable for space-constrained industrial applications requiring high torque output."
