EPICYCLIC GEAR TRAIN

[SRINIVASANIYER1]

I have

been trying to design an epicyclic gear train. though the assembly has mated, I am confused as to how to give the connections. I am sucessful in defining a gear connection between the sun and the planet. However I am not able to define a gear connection between the planet and the Annulus.

Hello,


you could follow this link:

I have explained it last year. I'll take a look into my old files and try to upload to files section. It looks that it should help some people.

yes,

files would be perfect. I have the same problem.
Designing gears and putting them together (working).
Result should work as a mechanism or an animation.

Strucky,


give me your email address and I will send you my assembly of planetary gear system.

Hello everybody,


I have problem to upload file, but hereis short explanation about my solution of planet mechanism.


1. Make "sub"assembly and define gear connection between central gear (sun) and planet.


2. Make a assembly of ring gear (annulus) and subassembly created before. Here you could define gear connection between planet and gear. If you have more planets, one gear connection is enough.


3. Define servo motor, but be sure that youdefine the right pin. You have to use pin of first subassembly.


My solutionincludeassembly and subassembly. Every time when I tried to makeone assembly I had problem with the central gear.


So, any comments are appreciate. If someone want to see my assy, please send me your e-mail adress.


Best regards,

Please send me your assembly. By the way if you suppress all the features in model tree your assembly size will become too small and can be easily emailed.

Thank you Jan21,


I shall try as per your instructions.

Hello everybody !!!

I have got it!!!!! attaching herewith a RAR file showing the joint connections and the gear connection. The gears have not been shown with teeth but as cylindrical surfaces but with gear connection. The sun, Planet and Annulus are 20, 50 and 120 teeth respectively. The gearing ratio as per the analysis run is 7, which matches with the theoretical calculation.

(Three cheers to me...)


Thanks Jan21. I have assembled them differently without making a subassembly. I have spaced them deliberately so that the Joint axes are clearly visible and I do not make a mistake in selecting the right axis.

Hi all.. If you are looking for video file of Willson Planetary gear-box, you can find it over here

This is assembly of Willson only for visual understanding of Planetary gear-box.This is not real gear-box.When I created this assembly I used mechanismgear connections..I can sent here more pictures orvideos If you want..

Hi,

I just found this - have been trying to create a epicyclic geartrain for a while now. Please Jan21, or anyone who has the assembly and is still registered here, could you send the planetary gear train (as shown on page 1) to me please?

Thank you in advance
