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
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...

A gear reduction unit uses the countershaft shown in the figure. The solid steel shaft is simply supported by bearings at points O and C. Gear A receives power from another gear with the transmitted force FA applied at the 200 pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force Fa at the pressure angle shown. 0 350 mm 225 ma Gear A 500-mm dia Gear B 200 mm...

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...

2.The shaft shown in the figure is driven by a gear at the right keyways, drive a fan at eh left keyways, and supported by two deep grove ball bearings. The shaft is made of AISI 1020 cold- drawn steel. At steady state speed, the gear transmits a radial load of 230 Ibf and a tangential load of 633 Ibf at pitch diameter of 8 inch. Determine fatigue factor of safety at any potentially critical locations using the DE-Gerber failure...

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...
