Chapter 11, Problem 32P

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 bearings against the shaft at O as RO = −387j + 467k lbf, and at B as RB = 3l6j − 1615k lbf. Specify the bearings required, using an application factor of 1.2, a desired life of 40 kh, and a combined reliability goal of 0.95, assuming distribution data from manufacturer 2 in Table 11-6.

Problem 4. A 16-tooth 240 Bhn steel spur pinion having a pressure angle of 20° and rotating at 720 rev/min drives a 28-tooth 240 Bhn steel gear having a 2.5 -in face and a diametral pitch of 5 teeth/in. Find the factor of safety of this drive based on bending strength if 17.5 hp is transmitted. Use Ko=Ks=1, Km=1.6 and Qv=7.
A gear-reduction unit uses the countershaft depicted in the figure. Find the two bearing reactions.The bearings are to be angular-contact ball bearings, having a desired life of 60 kh when used at 330 rev/min. Use 1.2 for the application factor and a reliability goal for the bearing pair of 0.92
Question 1: The figure shows a 16T 20° straight bevel pinion driving a 32T gear, and the location of the bearing centerlines. Pinion shaft a receives 2.5 hp at 248 rev/min. Determine the bearing reactions at A and B if A is to take both radial and thrust loads. On-Screen Keyboard Esc 1 3. 4 5 6.
