Design Fabrication and Testing of Gearbox for Fault Detection.

Abstract

This project work focused on the design and testing of gearbox for fault detection. Gearboxes are very important things in many industries applications. Thus the interest for their health monitoring is growing and effective diagnostic techniques and methodologies are the objective of previous studies. Here we are going to detect different types of fault which occurs in gearbox. There are mainly three types of fault occurs. These faults are slightly worn, medium worn, broken teeth. With the help of vibration study (due to gears fault) through oscilloscope we can design such kind of system which can detect what kind of fault a gearbox has. A multistage faulty gearbox is used in the present study. The test setup comprises of a multistage gearbox, driven by an induction motor and loaded by a generator or by a brake motor. The gearbox is an automotive transmission gearbox with five gears including back gear, such as 1st, 2nd, 3rd, 4th and back gears, under synchrony-meshed condition.
Here each gear will be tested under the constant load and constant speed (RPM) conditions.
