GEAR FORMULAS:
In order to draw a gearwheel, it is necessary to define the dimensions required. The following formulas are used to calculate the dimensions shown in the adjacent figure.
Do= Pitch diameter Do= M (Module). Z (Number of teeth) |
Dt=Base circle diameter Dt=Do.Cos20° |
Dü=Tooth thickness at tip Dü=Do+(2.M) |
Dd=Tooth thickness at base circle Dd=Do-2,33 . M |
Tooth thickness=t/2 t=Step t=M.π |
B=Tooth width B=10 . M |
