Key Terms
Te r m Definition
bearing calculation Calculates limiting value, dynamic and static load rating, dynamic and static
equivalent load, and fatigue life of bearing in revolutions and hours.
centerline Line in the center of a symmetrical object. When you create centerlines, you
specify the start and end points.
chamfer A beveled surface between two faces or surfaces.
dynamic calculation Calculation required for a revolving bearing. The result is the Adjusted Rating Life.
This is the life of the bearing associated with 90% reliability with contemporary,
commonly used material, and under conventional operating conditions. With the
number of revolutions you get the life in working hours.
dynamic dragging The act of determining the size of a standard part with the cursor while inserting
it into a side view. The standard part is displayed dynamically on the screen and
can be dragged to the next possible size and length. The values (sizes) are taken
from the Standard parts database.
shaft generator Tool to draw rotationally symmetric parts.
UCS User coordinate system. Designated by arrows that signify the XY coordinates.
Establishes a construction plane and simplifies location of 3D points. Provides
visual reference for positioning a surface.
