Design Approaches for Employing Enhanced Transmission Efficiency in over Head Cranes

The coupling is the device which is used to connect two shaft together at their ends for the purpose of transmitting the power or the torque. Further, the couplings are used to accommodate misalignment and also to compensate end movement in the system. Though the couplings are used in many area but this research is focusing on the use of coupling in Over Head Crane. Over the years, a variety of different approaches have been made to attain improvements in design of coupling tooth area whether it is crown one or straight one. Also the improvement is done in the area of misalignment compensation. Also the research have been done on the load carrying capacity of the coupling hub teeth and also on the rigidity of the coupling tooth. But here, this research have put attention on to increase the torque transmitting capacity of the coupling. To achieve the goal, here in this research there is no geometric modification done. As material selection is the part of designing, so by selecting proper and better material with good strength to weight ratio can attain the goal of better torque transmission. Here FEA is done on both coupling with existing material and modified material and from the FEA and theoretical results, it is found that the increase in torque transmission efficiency by choosing proper material is about 28.57%.
