Stand on soapbox: I would suggest getting up to speed in visualizing things in the 2D plane. No matter what software package you use, the final result will be a drawing that will be in 2D and you will have to be able to read it. Don't let the solid modelling get you complacant or lazy in this regard. Step off soapbox. BTW...some of the best work I have ever seen was hand sketched and worked out from there.heman said:it just took me 1/2 hour in 3dsmax but Autocad in 2 hrs. i could make only part of that..I tried to use these software not for dimensioning but for my own purpose of seeing things.
It just doesn't work like that. If all you had to do was to put something into a program and then wait for the magic box to spit out that things were OK, then engineers would not be needed any longer. You have to do the analysis. You need to define what the key elements of this machine are and what criteria need to be fulfilled with it. Software and computers are tools that are no different than the pencil in your pocket. Treat them as such, not a panacea. Use that wonderful tool between your ears! Also, what do you mean by "which parts are required"? If something isn't necessary, whay include them in the design? Hey...how'd I get back up here...heman said:i thought that by using softwares i will be able to visualise that everything works correctly or not...Is there any way to judge that it will succeed...like knowing which parts are not required..any software which judges the mechanics of the system..
By the way which software is used mostly by engineers for doing such things..

If you need the speed that high, then all that's required is still much simpler than what you've shown. Two shafts side by side, linked with a 9:1 spur gear set will do it. Your crank handle turns the big gear, which then drives the one attached to the paddle shaft nine times faster. It will also take less input effort to achieve that speed, because there are fewer points at which mechanical losses will occur.

Hmmm... for some reason, it's appearing with some lines missing. That's weird, because it's correct on the Image Shack site.[/QUOTE]
Danger,,
That was the thing we initially had in mind i.e. initial diagram i posted on top shows that... but the problem with that design is that it gives input in horizontal plane but since the rotation in vertical plane is more preferable than in horizontal direction..just an engineering aspect,,thats why we finally had to attach the bevel gear...
