Abstract
Gearless transmission which is compact and portable equipment, which is skillful and is having something practice in the transmitting power at right angle without 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.
The real time study is carried out by applying a motor to one of the shafts supported on bearings. Motion analysis is performed by running the mechanism at 15 revolutions per minute; reaction forces and reaction moment are plotted against clock run of 5 seconds by using post processor.
Similar motion analysis is carried out at different higher revolutions per minute and peak values of forces and moments are taken from the plot and compared with allowable stress. Theoretical calculations are made to obtain allowable stress by making use of design data values. As a result, response of elbow rod and hub is investigated to find the permissible speed of mechanism. Further simulation is performed to verify the motion analysis results.
