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 T of 1000 N 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 3200 N for bearing A and 2400 N for bearing B. The desired life for each bearing is 100 kh at a speed of 180 rev/min with a 90 percent reliability. The first iteration of the shaft design indicates approximate diameters of 30 mm at A and at B. Select suitable tapered roller bearings. B

The picture shows the rear swivel axle bearing design of a 4-wheel wagon. It is known that the speed of the wagon wheels is n = 37 rpm. The total radial load carried by the wagon is given as Fr= 16060 Newtons. In addition, due to road conditions, Fa axial load is applied to the wagon. If the axial load on the A bearing is 10% of the radial (vertical) load on this bearing, calculate the dynamic load number (C) of the bearing in the A bearing in Newtons for 18616 hours of life. fo*Fa/Co = 0.345 Pi=3.14
