1) Description of Rack Gear
A rack is a special type of gear, which is equivalent to a part of a gear with an infinitely large diameter.
It transforms the circular motion into a linear motion by unfolding the circumference into a straight line,
with teeth distributed along the straight line. Through meshing with the gear, it realizes the conversion
between linear motion and rotational motion.
2) Feature of Rack Gear
a) The structure is simple, consisting of a series of evenly spaced teeth, which is convenient for processing and manufacturing.
b) The linear motion trajectory is precise, ensuring the straightness of the movement.
c) It can be combined with gears of different tooth counts and module numbers, and has good versatility.
3) Advantage of Rack Gear
a) The transmission efficiency is high, and the energy loss is relatively small.
b) The movement is smooth, enabling uniform linear motion, reducing vibration and impact.
c) It can achieve linear motion with a large stroke, meeting the needs of different working scenarios.
4) Application of Rack Gear
It is widely used in the moving and lifting mechanisms of machine tools, such as milling machines and grinding machines,
to achieve precise linear feed motion; it is also used in the steering system of automobiles, converting the rotational motion of
the steering wheel into the linear motion of the steering wheels, ensuring precise vehicle steering.
