Abstract

Spur gear coupling is used to transfer torque and power from input shaft to output shaft. It is used in many applications such as automobile, aerospace, marine, industries etc. Transmission system consisting of gears and gear coupling are the major sources of vibrations. To reduce gear vibrations, method of phasing is used in this study. In this method input and output spur gear coupling sleeve are phased, in order to increase the number of teeth pairs in contact. Due to increased number of teeth pair in contact, mesh stiffness variation reduces. Mesh stiffness variation is a main contributor of production of internal excitation. It results in reduced amplitude of vibrations. The analytical study proved that maximum and minimum values of mesh stiffness for phased gear coupling are lower than non-phased gear coupling. This paper mainly focuses on experimentation of the proposed method. For this purpose experimental setup has been prepared and trials are taken to find the results with and without phasing of spur gear coupling. Experimental results show reduction in vibration parameter due to phasing arrangement of gear coupling sleeve. Maximum variation of vibration displacement and acceleration is observed between phased and non-phased arrangement at 1280 rpm speed and 3.5 Kg load.
