WebA gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. WebMar 9, 2024 · Finally you can cut this geometry from the gear's basic body. Since you have the involute it is possible to play around with profile shift, which just means to use different areas of the involute. Here is a positive profile shift x=0,5: Here is a negative profile shift x=-0,5: And here the overview to show the differences:
