Abstract

Almost all types of machine commonly used in the industry involve mechanical components and gear. In the meantime, the gear will provide vibration when the alignment occurs against the gear. Excessive gear could affect other components as high vibration level will lead to damage to a machine. Therefore, this study focuses on vibration analysis of two types of gear namely spur and helical gear caused by "misalignment" by using frequency spectrum. In addition, this study also focuses on the change in load applied to the gear. The load applied in this study was 0 Nm, 1.7 Nm and 3.4 Nm. The load imposed refer to Gunt Hamburg manual book. The central distance applied in the study was 0o, 30o, and -30o. Vibration is measured by using acceleration sensors located at two different locations to observe vibration tendency. The time taken for a machine operation for 20 minutes and the specified motor speed is 1800 rpm equivalent to 30 Hz. Each angle of gear misalignment and load applied combination will influence the vibration produced on the gear, the greater the load it, the higher the vibration value that occurs on the gear.
