Simple Question ?
Dear Mr. S. Ganesh,
please, could you clarify the intent of your post? Apart from being myself grateful for John's efforts, a quick search on the internet + evtlly some phone calls would have given you a first & substantial answer to the question. So, pls, what is the bulk handling systems background to your request?
Regards

It May Be A Very Wild And Mad Idea.
Thank you Mr.John Gateley for the link.
Dear Mr.Ronald,
You would have seen in encoders, weigh feeders, dozing conveyors thin hoses are used to connect drive and driven shafts. Hose clips are fixed to hold the hoses strongly on the shafts. Those hoses are thin and shorter for length.
I was wondering, if the same concept can be increased to bigger KW power and length ?
Presently very long shafts and knuckle joints are used. Cardon shafts (yoke and spline arrangements with knuckle joints) for vibrating equipments are being used. Would it be possible to replace them, by a hose arrangement ? Please imagine a very strong hose having flange joints on both ends to connect drive and driven machines. It will take care of both power transmission as well as with stand axial and radial vibrations.
It may or may not work. I know that it may be a very, very, wild and mad idea.
Or would this concept have been developed and successfully running somewhere ?
If anyone has come across, such application, please share your experience.
Thanks a lot & many regards, ■
Fifa Gets Inv0lved.
Now the goalposts get moved from proprietary tyre/torus couplings to a new concept of a short mining hose.
Mining hose is not as flexible as some people imagine but when it is it buckles. That is why the originally mentioned torus coupling was invented. Even then there are length limitations, as defined in the link above. To increase the spacing distance you might be able to use a number of couplings in series. This would divide the angular misalignment accordingly but there would be considerable wind up.
Cardan joints do not match the input and output velocities unless the shafts are absolutely parallel. This condition is practically impossible to achieve and the joints shake to destruction accordingly. Rzeppa joints have been universal for passenger car service since the late '50s and it amazes me that there has been no peer pressure to rate these constant velocity joints for truck etc. use. Then we could all use a satisfactory coupling and you wouldn't have to worry about protecting staff from rubber bullet shrapnel. ■

Hose Will Incur Lot Of Losses
Dear Mr. Ganesh,
Hose can surely serve a purpose but being flexible in nature, it will incure heavy losses in terms of torque and also the inconsistency in torque delivery. Since positive drives is a solution you may refer Fenner gear coupling or Fenner tyre coupling. ■
Re: Tyre Couplings Or Similar To Them
Hello,
In order to uphold the guarantee and warranty of the coupling, it is advisable to go by what the supplier says. The data from particular manufacturer will be in context of his design, and obviously there could be some difference in the data from manufacturers. In this situation, choosing some larger value will enable you to have more flexibilty in selecting the final supplier.

Tyre Couplings or Similar to Them
Dear experts,
What could be the maximum distance between the drive and driven flanges in a tyre coupling (or similar to such concepts ) ?
