Hey Everybody..!

I am trying to make cyclodial gears, for a clock assembly..
so I need to generate cyclodial curve for that..


I have the following inputs:

No of Teeth on Pinion
No of Teeth on Wheel
Wheel Dia
Pinion Dia

what will be the procedure to design the pinion and wheel?
does anyone know ..what's the exact formulas and step one need to follow..??

I would really appreciate your help in this regard.
Thanks!
Amar

Hi Amar,

Just go thru' this URL....

=======================================
http://watchmaking.csparks.com/CycloidalGears/CycloidCalculator.html
=======================================

In this calculator, you need to enter 3 inputs :-
MODULE, No of WHEEL TEETH, No of PINION TEETH & you can get the following output results :-


Circular Pitch
Dedendum
Gear ratio
Addendum factor
Addendum
Addendum radius
Pitch diameter of wheel
Pitch diameter of pinion


ALL CALCULATIONS ARE AVAILABLE IN "ENGLISH" STANDARDS ONLY.

Bye.


PS : you can browse through Google website for all these search material, in future.

Regards
Vijayakanth.

involute are not used here bcoz...generally the wheels and pinions in clocks differ from the normal types of invoulte form, as the wheel and pinion is gearing up in clocks, whereas in gears box of a motor car (involute form) the reverse takes place, consequently a different tooth shape is required which is called cyclodial form, which helps to reduce the friction and improve the efficiency of the drive.


if anyone have the perfect answer (procedure) to design the cyclodial gears..plz reply me asap.

thanks!!!
Amar
