The objective of this paper is to design the shaft for maize seller and to analyze the structural behaviors on the shaft due to applied fluctuating torque, bending moment and shearing force on it. This paper discusses about the calculation parameters of shaft design and bearings selection for maize shelling machine produced in Aung-Paddy Thresher Industrial Zone at Mandalay. Weight of threshing drum (shelling cylinder), fan blades, pulley and bearings are exerted on the shaft which is constructed with gray cast iron. The shaft diameter is 25 mm and length is 942 mm. The rotating speed of shaft is 302 rpm at power supplied 1.1 kW. Solid Works software is used for modeling of shaft and analysis of the shaft is done by ANSYS software. The stress distribution on shaft is expressed by theoretically and numerically approach. The theoretical and numerical results data of maximum von-Mises stresses are 92.699 MPa and 87.659 MPa for gray cast iron. The percentage error is 5%. The yield strength of gray cast iron is 276 MPa. The theoretical and numerical results of maximum von-Mises stresses are not exceed the yield strength. Therefore, this design is satisfied.
