Useful knowledge to the understanding: concepts and determinants for cylindrical **gears** Data entry**Geometry of involute gears** - tec-scienceOct 31, 2018 · Introduction. In mechanical engineering, the **involute** is used almost exclusively as a tooth form for **gears**.Such **gears** are called **involute gears**.The use of **involute** toothing is due on the one hand to the favorable meshing (engagement of two gearwheels). On the other hand, **involute gears** can be manufactured cost-effectively due to the relatively simple tool geometry.**Involute Curve** - an overview | ScienceDirect TopicsAn **involute curve** can be constructed by tracing the end of a cord unwound from the periphery of a circular disk (see Figure **10**.65).The contour of the **involute curve** is governed only by the diameter of the disk from which it is developed. As there is no limit to the length of an **involute curve**, in practice, the best portion to meet working conditions has to be chosen.
