The following figure shows two bearings supporting a
0.08×10^3-rpm shaft and gear. The bearing on the left carries a
4.07kN radial load and 0.32kN thrust load. The loading is
borderline between “light” and “moderate” impact. The required life
is 4000 hours with only 2% probability of failure. What is the
required bearing capacity in kN? Solve to 2 decimal spaces. An
error of 5% is allowed for. T4 Q3.PNG

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...

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.

(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...
