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...

Figure Q1 shows a gear train consists of four spur gears A, B, C and D to be designed for a specific
mechanism. The power transmitted by gear A is 5 kW at rotational speed of 720 rpm
counterclockwise direction. Number of teeth (N) for gears A,B,C and D are respectively 20, 50,
30 and 60. The module and pressure angle of the gears are respectively 4 mm and 20o

(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...
