11-32 The figure shown is a geared countershaft with an overhanging pinion at C. Select an angular- contact ball bearing from Table 11-2 for mounting at O and an 02-series cylindrical roller bearing from Table 11-3 for mounting at B. The force on gear A is FA-600 lbf, and the shaft is to run at a speed of 420 rev/min. Solution of the statics problem gives force of bear- ings against the shaft at O as Ro--387] 467k lbf, and...
The figure is a schematic drawing of a countershaft that supports two V-belt pulleys. Thecounterchae rpm and the bearings are to have manufacturer 2 in Table 11-6 The belt tension on the loose side of pulley runs at 2000 alife of 80 kh at a combined reliability of 0.98, assuming distribution data from A is f % of the tension on the tight side. GIVEN: W L andf- 19 a) Select deep-groove bearings from Table 11-2 for use at O...
Shown in the figure is a gear driven squeeze roll which mates with an idler roll (not shown). The roll is designed to exert a normal force of 30 lb/in of roll length and a pull of 24 lb/in on the material being processed. The roll speed is 300 rev/min and an L10 life of 30 kh is desired. Use an application factor for poor bearing seals and commercial gearing. Select a pair of radial contact 6300-series medium, deep groove...

tables that would help u Q-4 An 02-series single-row deep-groove ball bearing with a 30-mm bore (see Tables 11-1 and 11-2 for specifications) is loaded with a 2-kN axial load and a 5-KN radial load. The inner ring rotates at 400 rev/min. (a) Determine the equivalent radial load that will be experienced by this particular bearing. [15 pts.] (6) Determine the predicted life (in revolutions) that this bearing could be expected to give in this application with a 99 percent...
PROBLEM 2 and 3 (journal bearing) A gear-reduction unit uses the countershaft depicted in the figurel. The reactions at bearing positions and C, are shown in figure 2. Note that only bearing position take the axial load. The bearing at position is to be angular-contact ball bearings, having a desired life of 50 kh when used at 300 rev/min. Use 1.2 for the application factor and a reliability goal for the bearing pair of 0.96, assuming distribution data from manufacturer...

Can somone show me how to do the 1st problem? Need to find the LS and SS for the fit and the LH and SH for the hole. Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...
