Design Worm Gearing Of Remotely Operated Vehicle Under Uncertainty

In remotely operated vehicle (ROV), worm gearing is usually used to transfer movement and power between two staggered axes. In the design process of worm gearing, complex gear face and the exist of uncertainty make its design and modeling so difficult will affect its reliability. In this paper, a reliability-based design (RBD) method is proposed for worm gearing of remotely operated vehicle under two types uncertainties, and the first-order reliability method (FORM) is used to calculate the reliability of worm gearing. Finally, an engineering example is used to illustrate the effectiveness of the reliability design method for worm gearing of remotely operated vehicle.
