Design Of Freewheel Coupling

Generator is a machine in which mechanical energy is converted to electrical energy. Generators are made in a wide range of sizes, from very small machines with a few watts of power output to very large central-station generators providing 1000 MW or more [1]. Within a generator set, there is a radiator connected to the engine, by means of coupling. Commonly, fixed couplings are used which could create a damaging high torsional effect. The objective of this project is to design and develop a freewheel coupling that can overcome the problems mentioned. The scope of study includes designing the new coupling, the fabrications and the improvement of the existed coupling used. There are many works that need to be carried out especially in designing and fabricating. It involves researches, software skills especially AUTOCAD, purchasing raw material, skills on using related machines for fabrication part and many more. At the end of the project, a prototype of a new design of coupling should be made. All the information that related to the design and anything involved during the process to complete the project will be compiled in a final report. This project will benefit the most to the packager since it can reduce the cost since they do not have to import the coupling from oversea. Because of that, they can propose lower price of a generator set in their bidding process. The other option is they still can maintain the same price, then the packager can gain more profit in their project. It will also benefit the end user or the clients since they can buy a generator set not only with lower price, but also with improved design which overcome the problem stated above.
