Force Analysis Note that the magnitude and direction of the reaction forces acting on the shaft is a function of the crank angle. You can design the shaft as if the loadings on the shaft changes between 0 and the value corresponding to the maximum torque case. In reality, for the critical locations, you need to plot the bending moment with respect to the crank angle and angular position of the shaft and determine the critical position (crank angle and angular position) from the 3D plot. At the maximum torque position, 812-115, 013-7, 014-274, 015-86, and the sum of the punching and inertia forces acting on the ram, Fp, is 10 kN in the direction shown in Figure 4. The weight of the ram is supported by pneumatic supporting unit during up and down motion. The belt forces can be calculated from the equation, Fea, where f is the coefficient of F friction and a is the angle of wrap, shown in Figure 5.
