Design and Analysis of Gear Box Test Bench to Test Shift Performance and Leakage

Mechanical Engineering

Transmission is one of the critical and most important systems of an automobile and it largely affects the driving performance, safety and riding comfort of the vehicle. Gearbox is an important element in power transmission drives of most of the mechanical systems. Therefore, it is important to ensure the performance of gearbox prior to its usage in actual systems. The performance of gearbox should be tested to ensure the trouble free functioning of gearbox. There are various tests that should be performed on the gearbox to ensure its working performance which includes shift performance test, leak test and noise test. Gear shifting mechanism is link between driver and vehicle. The shift force is an essential criterion for the operating quality of gear shift. Gearbox noise is sometimes the dominating noise in commercial vehicles which has to be minimum. Leakage from gearbox is also one of critical problem. This work presents the design of a test bench for gear box to test a gearbox at the end of assembly line to check leakage, noise, gear shifting feeling and shift load in driving and dragging condition. This includes design of fixture for gearbox, clamping arrangement, gear shifting arrangement, design of oil dispensing, extraction and filtration unit. Also the FEA of fixture components has been carried out.
