Briefing
Detailed
divided into straight teeth rack and helical rack, which are paired with spur gear
and helical cylindrical gear respectively. Rack profile is straight line instead of
involute (for tooth face is plane), equivalent to cylindrical gear with infinite radius.
(1) because the rack tooth profile is straight, so the points on the tooth profile have
the same pressure angle, which is equal to the inclination angle of the tooth profile.
This angle is called the gear angle, and the standard value is 20 degrees.
(2) any straight line parallel to the top line of the tooth has the same tooth distance
and modulus.
(3) a line parallel to the top line and the tooth thickness equal to the width of the
alveolus is called the dividing line (middle line). It is the base line for calculating
the size of th size of the rack.
