Gears / Gear Racks

Gears and racks are types of gears. Gears are discs with teeth arranged, racks are plates with teeth arranged. Gears are used to transmit rotational power between gears, and the power ratio can be changed. Racks are used to convert the rotational power of gears into linear motion. Used in various general machines to transmit gear power. It is necessary to combine things that mesh according to the tooth width. In addition to gears that transmit power in the same direction, bevel gears can change the power transmission angle. Miter gears, bevel gears, etc. are examples of bevel gears.
