Question 2 The shaft shown below is rotating at 650 rpm, and it receives 7.5 hp through a flexible coupling. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20 degrees and a helix angle of 15 degrees. The pitch diameter for the gear is 4.141 inches (De) and the Tangential (Wu), radial (W) and axial/thrust (W) are shown below on the drawing. The shaft is to be made...
In the figure below, a rotating shaft (for speed reducing gearbox) is subjected to radial forces at A= 400 lbr
In the figure below, a rotating shaft (for speed reducing gearbox) is subjected to radial forces at A= 400 lbr .and at C = 800 Ibr. These radial forces are caused by spur gears mounted to shaft (a result of the pressure angle of the teeth, 20 degrees) that mesh with 2 other spur gears, not shown. Also, The shaft transmits a constant torque of 11110 in-lbr (925 ft-lbr) due to the tangential force (Wt: transmitted load) at C of...
