Design and experimental analysis of tooth impact test rig for spur gear

Mechanical Engineering

This project is about the design and analysis of a prototype of tooth impact test rig for spur gear. The test rig was fabricated and analysis was conducted to study its’ limitation and capabilities. The design of the rig is analyzed to ensure that there will be no problem occurring during the test and reliable data can be obtained. From the result of the analysis, the maximum amount of load that can be applied, the factor of safety of the machine, the stresses on the test rig parts were determined. This is important in the design consideration of the test rig. The materials used for the fabrication of the test rig were also discussed and analyzed. Static analysis of spur gear will be perform using ANSYS 19 workbench. Modeling of test rig and spur gear will be design using CATIA V5R20 software. Based from the results, there were limitations found from the initial design and the test rig design needs to be improved in order for the test rig to operate properly. Experimental study using strain gage to determine the strain at the gear tooth can be conducted with the availability of this test rig.
