Given: A winch will be operated by a worm- worm gear set, as schematically shown below. The worm will be powered by an electric motor that rotates at 1,725 rpm. The expected speed of the worm gear is between 30 and 35 rpm. The peak torque requirement for the winch is about 4,100 lbf-in, the operating ambient temperature is 120 °F, and the average output power doesn't have to exceed 0.7 hp. The winch drum radius is 6 in, and the winch operates 7 to 8 hours a day. Find: DRAW A FREE BODY DIAGRAM OF THE SHAFT HOLDING THE WORM GEAR and explain your reasoning for what you drew. Must be legible. Then draw shear, bending, and torque diagrams for the shaft holding the worm gear and show the calculations for how you got to those diagrams. Must be legible. base base coup- ling worm bearings shaft bearings motor worm gear coupling rope wir dru winch drum hook Front view Side view 区
