Calculating Shafts
In this tutorial, you use the shaft generator in AutoCAD
®
Mechanical to perform a calculation
on an existing shaft, and apply various loads to a supported shaft. Then you insert the results
into a drawing.
Key Terms
DefinitionTerm
A curve representing the vertical displacement of different points
along the member subjected to a load.
deflection line
The moment of all forces that act on the member to the left of a
section (a point along the member where bending moment needs
to be calculated) taken about the horizontal axis of the section.
bending mo-
ment
Safety to endurance or fracture under repetitive cycles of loads.fatigue factor
A support that prevents translation as well as rotation about all axes.fixed support
Any of several arrangements in a machine, especially toothed wheels,
that allow power to be passed from one part to another to control
the power, speed, or the direction of movement.
gear
The forces and moments that act on a part.load
A support that prevents translation as well as rotation about all axes.movable support
A change of cross section, such as an undercut, groove, hole or
shoulder. A notch leads to higher stress in the part. The flux of the
stress is interrupted or redirected.
