Q-1 The shaft shown in figure below, supported by and turns in the bearings A and B. The dimensions of the shaft are a = 120 mm and b = 30 mm. The forces on the bevel (conical) gear attached to the shaft are Wt = 4500 N, Wr = 2500 N, and Wa = 1000 N. The gear forces act at a radius R = 100 mm from the shaft axis. Determine the loads applied to the bearings (FrA...
The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20". The shaft transmits a torque to point A of TA = 340 N.m. The shaft is machined from steel with Sy= 420 MPa and Sut = 560 MPa. The fatigue...
please solve with details Question#1140Marksl The shaft shown in the figure is rotating at 650 rpm and it receives 5592.75 W through a flexible coupling at its right end. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20° and a helix angle of 15o. The pitch diameter for the gear is 105.1814 mm (4.141 in). A spacer is used to position the gear relative to bearing C. The...
