For all the possible gear ratio in fractions of seconds calculate
Change gears are mostly from two pairs of gears assembled, or double gear ratio:
- Milling of gears with the gear hob, gear hobbing, (PFAUTER).
(Gears of diferential for additional rotation of the workpiece during manufacturing of helical gears)
- For gear profile grinding machines, (NILES)
- For gear tooth forming machine, (MAAG, LORENZ)
(change gears for rolling processes)
- Thread grinding machine:
(change gears for the pitch, screw).
|actual value-gear ratio: i=
desired value: (given), or
Arithmetic expression, Based on the machine data
Only decimal point "." is allowed, never comma ","
Largest/smallest number of teeth in the existing gear wheel set
desired preciseness (on, e.g. rounded to seven decimal figures):
rounded desired value = rounded actual value-gear ratio
e.g., For gear profile grinding machines, (NILES),the gear ratio for change gears of differential is expected
in accordance with the following expression:
e.g., For a gear
In the input field for desired gear ratio is value,
or an arithmetic expression, referring to SQL-language entered.
- Modul: m=2,5
- number of teeth: z=38
- Helix angle: ß=15°
desired gear ratio:
pi()/180=angle in rad
or, for Helix angle of ß=15°22`18":
