The gearbox is one of the important industrial rotating equipment. Generally, high reliability and availability are crucial issues for this equipment. vibration condition monitoring (VCM) is a very good and useful technique for detecting the faults of the gearboxes. In this paper, a test rig design and development are explained. Some considerations including easy assembling and disassembling, the possibility of locating various faults, and the possibility of applying different operating conditions are taken into account. After manufacturing the test rig, an experiment scenario is planned and run. Two conditions, including assembling a couple of healthy gear and pinion, and assembling a chipped pinion and a healthy gear, are planned for the test. The results of vibration measurement for both scenarios are recorded. Using the time domain analysis as well as the frequency domain analysis, recorded vibrations in the two mentioned health conditions are compared. Results show that the designed and constructed test rig satisfies the initial aim of the design.
