The motor shown in the figure supplies 16.5 kW at 1540 rpm at A. Shafts (1) and (2) are each solid 28 mm diameter shafts. Shaft (1) is made of an aluminum alloy [ G=26 GPa], and shaft (2) is made of bronze [ G=45 GPa]. The shaft lengths are L1=3.3m and L2=2.9m, respectively. Gear B has 56 teeth, and gear C has 97 teeth. The bearings shown permit free rotation of the shafts. Determine: the rotation angle of gear D with respect to flange A. [Answer φD/A = 0.314 rad]
The solid steel rotating shaft in the figure is supported at B and C, and is driven by a gear, not seen, which is linked to spur gear D which has a pitch diameter of 150 mm. The drive gear force F acts at a pressure angle of 20 degrees. The shaft transmits a torque to point A of Ta-350 N.m. The properties of machined steel shaft are Sy-420 MPa and Sut-560MPa. Use a safety factor of 2.5 and determine the minimum allowable diameter in section B and C. Assume sharp felt radii at the bearing shoulders to estimate the stress concentration factors.Explain.
The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600 rpm and is supported in rolling bearings at A and B. The applied forces are F1 = 1600 lbf and F2 = 640 lbf. A steady torque of 1600 lbf·in is being transmitted through the shaft between the points of application of the forces.
