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...
is the factor of safety guarding against damaging distortion? What is the factor of safety guard- ing against a fatigue failure? If the shaft turns out to be unsatisfactory, what would you rec- ommend to correct the problem? A shaft is to be designed to support the spur pinion and helical gear shown in th two bearings spaced 28 in center-to-center. Bearing A is a cylindrical roller and is to take only radial load; bearing B is to take the...
can you please explain how to calculate the axial load for each gear and supporting load for each bearing? thank you! Task 1: A shaft is to be designed to support the spur pinion and helical gear shown in the figure below on two bearings spaced 700 mm center-to-center. Bearing A is a cylindrical roller bearing and has to take only radial load; bearing B has to take the thrust load produced by the helical gear and its share of...
A straight-bevel gear mesh is utilized to transform the rotation about a horizontal shaft of a motor-driven pinion into rotation of an output gear about a vertical shaft as shown in Fig. 1. The pressure angle f = 20°. The pinion shaft rotates at 900 rpm. a. Both pinion and gear are Grade 2 steel through-hardened at 250 Brinell and are uncrowned. The quality number is 9 and the desired life is 30,000 hours with a 0.999 reliability. For a...
QUESTION 10 The shaft shown in the figure is driven by a gear at the right keyway, drives a fan at the left keyway, and is supported by two deep-groove ball bearings at locations A and B. The shaft is made from AISI 1045 cold-drawn steel. At steady-state speed, the gear transmits a radial load of 300 lbf and a tangential load of 700 lbf at a pitch diameter of 8 in. Assume that the weight and axial load of...

Question 2 The shaft shown below is rotating at 650 rpm, and it receives 7.5 hp through a flexible coupling. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20 degrees and a helix angle of 15 degrees. The pitch diameter for the gear is 4.141 inches (De) and the Tangential (Wu), radial (W) and axial/thrust (W) are shown below on the drawing. The shaft is to be made...
Figure below shows the load components acting on a helical gear mounted on a simply supported shaft. Bearing B takes thrust. A flexible coupling for transmitting torque attaches to the right end of the shaft. The left end is free. 1-Draw load, shear force, and bending moment diagrams for the shaft, in both the horizontal and vertical planes. 2- Identify the most critically loaded shaft cross section, and for this location determine the diameter theoretically required for infinite life. Assume...
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...
