In fact, the integration of rack and pinion into a conveyor is a unique approach. The teeth of the sprocket resemble a straightened, extended strip. This type of conveyance is no longer a simple circular movement by itself, but rather a form that allows the transfer of force through the strip.

In comparison to the composition of gears, its significant characteristics are:

(1) Its tooth profile is straight, so all the normals on it are in a parallel state. In the transmission process, it operates in a straight manner, maintaining consistent speed and direction. All the tooth shapes on it are identical, with a straight-line inclination angle of 20 degrees.

(2) Each tooth on the gear has a side square tooth profile that is relatively parallel, ensuring that the tooth thickness and slot width are the same, both on the pitch line and on the tooth rack's pitch line. This serves as the baseline for the size of each position.
