 Help required with Cyclodial Gears.. Post Reply Forum
 Posted by: akc001 ® 03/22/2005, 16:39:13 Author Profile Mail author Edit 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 Diawhat 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

 Posted by: akc001 ® 03/29/2005, 09:11:38 Author Profile Mail author Edit 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!!!
