Mechanical Project on Gearless Transmission

This is a Mechanical final year project work on Gearless Transmission which is a compact and portable equipment, which is skillful and is having something practice in the transmitting power at right angle with out any gears being manufactured. This project is the equipment useful to improve the quality of the gear being manufactured and can be made in less time. This project uses El-bow mechanism which is an ingenious link mechanism of slider and kinematic chain principle. This is also called as “gearless transmission mechanism” and is very useful for transmitting motion at right angles. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.



The Gearless transmission or El-bow mechanism is a device for transmitting motions at any fixed angle between the driving and driven shaft. The synthesis of this mechanism would reveal that it comprises of a number of pins would be between 3 to 8 the more the pins the smoother the operation. These pins slide inside hollow cylinders thus formatting a sliding pair.

Our mechanism has 3 such sliding pairs. These cylinders are placed in a Hollow pipe and are fastened at 120* to each other. This whole assembly is mounted on brackets wooden table. Power is supplied by an electric motor. The working of the mechanism is understood by the diagram. An unused form of transmission of power on shaft located at an angle.

The featured product has its widest application as an extension for a socket wrench. This report includes working principle, machine design, cost estimation etc. Use this Mechanical report for your reference and study work only.
