Spur Gears and Racks

Spur Gear: A standard engineering element used to connect shafts. In the case of identical teeth, it is used to transfer the current torque, in the case of different teeth, it implements a gear ratio. If a gear with a larger number of teeth is the driving gear and the smaller one is the driven, then the speed increases in proportion to their number of teeth, and the torque decreases. If we change the number of teeth on the axles, the effect will be the exact opposite compared to the previous state.

Rack: Rotary motions can be converted into linear motion with the help of racks.

Material selection: C45 steel, plastic PA6 + fiberglass (Polyamide) or plastic POM
