Design and Analysis of Stepped Shaft in Inclined Position

Shaft is an important machine element and is required to design with extreme accuracy of well-functioning of a machine. The shaft is generally acted upon by bending moment, torsion and axial force. A spindle is a short rotating shaft. Spindles are used in all machine tools such as the small drive shaft of a lathe or the spindle of a drilling machine. There is a requirement of some specific machines to have a spindle in inclined position. Determination of loads acting on shaft and angle of inclination of shaft is an important task during design. We have taken maximum shear stress theory into consideration. It also generates the diagrams for horizontal, vertical and resultant bending moments over the lengths of the shaft. In this paper we used “CREO PARAMETRIC� software for modeling and “ANSYS� for checking failure of a design. ANSYS is used extensively for checking the stresses in a component and deflection of shaft gives complete idea of displacement of component. It is accurate and also has a number of built in functions which makes it versatile. As different computer software are used shaft design becomes easy, fast and error free.
