7-25 A shaft is to be designed to support the spur pinion and helical gear shown in the figure on two bearings spaced 700 mm center-to-center. Bearing A is a cylindrical roller and is to take only radial load; bearingB is to take the thrust load of 900 N produced by the helical gear and its share of the radial load. The bearing at B can be a bal bearing. The radial loads of both gears are in the same...

(5) The gear reduction unit shown has a gear that is press fit onto a cylindrical sleeve that rotates around a stationary shaft. The helical gear transmits an axial thrust load of 300 Ibf as shown in the figure. Tangential and radial loads (not shown) are also transmitted through the gear, producing radial ground reaction forces at the bearings of 900 lbf for bearing A and 650 lbf for bearing B. The desired life for each bearing is 90 kh...

Consider the simplified transmision sample problem shown in Figure 1 below. In this figure, mating gears were shown to only exert tangential forces on each other. In reality, mating spur gear teeth will exert both tangential forces and radial forces2 due to the involute profile shape of the teeth (see Chapter 15, Figure 15.7). Let the diameters of gears B and D be 4.25 in while the diameters of gears A and C be 2.25 in. All other dimensions and...

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...
