Do you know the classification of gear and rack

The gear rack is usually used together with the slide rail, and its use has played a very important role. Do you know the classification of gear rack? The following is for you to answer:

Its classification can be divided according to tooth shape, tooth line shape, gear shape, tooth surface, manufacturing method, etc; They also have other classifications, such as:

* According to tooth shape, they are classified as: tooth height, deflection, force angle, tooth profile curve, etc

* According to the shape of tooth line, the gears are classified as gear, curve, herringbone, helical gear, etc

* According to the shape, the gears are: rack, bevel gear, cylindrical, worm-worm gear, non-circular gear, etc

* Classified according to the surface: internal gear and external gear

* Classified by manufacturing methods: cutting, casting, rolling, sintering, etc

* The main categories of rack are: straight rack and diagonal rack

Note:

* The tooth root circle is larger than the top circle of the internal gear tooth, while the tooth root circle is smaller than the top circle of the external gear tooth

* It is not allowed to use with straight cylindrical gear and helical cylindrical gear

* is a straight rack tooth profile, not an involute tooth profile. For the tooth surface, it is planar, which is equivalent to the radius of the indexing circle of the quality-based large cylindrical gear
