In fact, the combination of tooth racks and gears into a transmission is a special method. The chain wheel's bar is like a stretched and stretched one, and this kind of transmission is not just a circular operation completed by itself, but a form of force transmission that can be achieved by running on the bar.

Compared to the composition of gears, their important characteristics are:

(1) Its tooth profile is straight, so all normals on it are in a parallel state. In the case of transmission, it operates as a straight line, with the same speed and orientation. All the tooth angles on it are the same, and the standard inclination angle of the straight line is 20 degrees.

(2) The square tooth profile on the same side of each tooth on it is relatively parallel, so whether it is on the indexing line or on the indexing line of the tooth top rack, the tooth thickness and groove width are the same, which is the reference line to ensure the size of each position.
