| Involute |
|
The curve
formed by the path of a point on a straight line as the line unwinds
along the circumference of a circle. This curve is generally used
as the profile of gear teeth.
Therefore, if a circular disc was placed on a drawing board, an involute
curve would be scribed by the end of a taut line if it was unwound
from the disc. The disc represents what is known as the base circle
because this is the circle from which the involute tooth curves are
derived. |
