Sorry didnt get what aerodynamic shorouds are??
Secondly I understand what your saying about the sofisticated software to study drag. Could I use Solidworks CosmosFlow works and tr maybe a CFD analysis??
To GregLocock, thanks for that formula but how can i get power when i know the torque and...
Think of it like a centrifuge. It has a central shaft vertically downwards connected to some gears. The disc is spinning at 3000RPM, with test tubes, say four of them hanging downwards. Now when these tubes spin fast, due to centrifugal force they stretch outwards almost 90 degrees. I already...
Hi guys, im looking for a simple formula to calculate the aerodynmaic drag on a spinning disc. The disc is basically the rotor for a mechanical centrifuge where the test tubes are hanging downwards and experience drag at 3000RPM.
Any help would be very nice thanks
Quick question: I have a spwound spiral spring sitting on a shaft and when it unwinds it delivers 10.2Nm Torque input. This torque goes through gearing system and eventually rotates a disc at the top. Because the spring releases energy so fast the speed is not controlled. How can i control the...
Thanks for the reply and an informative brief on what considerations need to be considered. To be honest I dont know much about the information you gave but I hope the following helps.
Torque on input shaft which is 40mm dia is 10.2 Nm which is horizontal going into gearing system. Then output...
Thanks for that, what i gathered is that its too simple (the gear trains solution). What i would like to know is calculating Epicyclic Ratio of 1:1500. I looked on the net but couldnt even understand how its all done.
1) There is an input shaft horizontal 40mm dia with spiral spring mounted on...

Hi everyone im pretty new to the forum and just wanted to ask some q's about gear ratios and compound gear trains. I need to acheive an overall ratio of 1500:1 from the energy released by a spiral spring with 20 turns mounted on a 40mm dia shaft. Thickness of spring is 1.5mm with 30mm width. max...
