It will be necessary to do the following: (a) Determine the magnitude of the torque in the shaft at all points (b) Compute the forces acting on the shaft at all powertransmitting elements (c) Compute the reactions at the bearings (d) Draw the complete load, shear, and bending moment diagrams

Chat NowShafts are designed on the basis of strength or rigidity or both. Design based on strength is to ensure that stress at any location of the shaft does not exceed the material yield stress. Design based on rigidity is to ensure that maximum deflection (because of bending) and maximum twist (due to torsion) of the shaft is within the allowable limits.

Chat NowA particular problem occurs when designs of gearbox, which may have been designed mainly for horizontal shaft orientation, are used with vertical shafts. A typical problem which can arise is that any debris or contaminants accumulate in the bottom, and result in wear of the bottom bearings.

Chat NowHigh-speed shafts require not only higher shaft stiff-ness but also stiff bearing supports, machine housings, etc. High-speed shafts must be carefully checked for static and dynamic unbalance and for first-and second-order critical speeds. The design of shafts in some cases, such as those for turbopumps, is dictated by shaft

Chat NowA vehicle's drive shaft--the rotating object located between the differentials and gear box--helps it switch from idle to drive; without it, a vehicle would never move. Usually, a drive shaft does not fail instantaneously, and deterioration happens over time. Accordingly, if drive shaft problems …
