Question: need help getting reaction forces at bearings...

Question details

16.15. The helical gear reducer below is driven at 1000 rpm by a motor developing 15 kW. The teeth have helix angle 4-0.50 rad, and normal pressure angle φη:0.35 rad. Pitch diameters are 70 mm and 210 mm for pinion and gear. a) Calculate the torque at the input shaft, and calculate the 3 components of the gear-tooth force b) Make a sketch like the one in the figure except with the shafts separated vertically, and show all tooth force components acting on both gears. See next page cCalculate all support reactions at A, B, C, and D. For Shaft AB only, plot the bending moment diagrams for both views, find the locations of the largest bending moment, and the resultant moment 65 40 mm Load Rotation Motor 250 mm 140 mm

Shaft AB - Assume Bearing A takes the thrust (axial) load, draw the X-Y and Y-Z views of the shaft. Plot the bending moment diagrams for both views, find the locations of the largest bending moment, and the resultant moment. Pinion 40 mm te= 4092 N Fr- 1702 N a223S N Partial answers: Az 1900 N, Av-231 N, RA-1914 N, resultant M 268 N-m
