For a project I am doing I need to increase out put speed to 515 rpm from 1rpm with no more than a 20% decrease in torque, I need help I have been trying a lot of things and can't figure it out.

I am working on a project that is using a pto generator and I need as far as I can figure 240 flbs of torque for continual use under a full load however I am limited with my power source to roughly about 500 flbs and due to the input I could possibly get up to 5 rpms I wish I could tell you more however my hands are tied with other specificsCWatters said:You can't do that with just a gearbox. As others have said if you step up the rpm by a factor of 515 you will step down the torque by the same factor. This is due to conservation of energy (law of physics).
There is another potential problem.. Any friction in the bearings of the output shaft is seen at the input shaft but magnified 515 times. This makes frequently makes high ratio step up gearboxes impractical.
Perhaps if you explain why you need such a step up we can figure out another way. Is this anything to do with hand cranked generators?

Ok yes I do thank you all for the helpCWatters said:So your power source is..
500 flbs at 5 rpm which is about 0.5 HP (355W)
Your load requires...
240 flbs at 515 rpm which is about 23 HP (17,500W)
See the impossibility of the problem?
What is the formula you used to figure this outCWatters said:So your power source is..

Output speed is the rate at which a system or process produces results. It is important because a higher output speed can lead to increased efficiency and productivity.
Some ways to increase output speed include optimizing processes, implementing automation, improving equipment or technology, and streamlining workflows.
Output speed can be measured by tracking the number of units or tasks completed within a given time frame. Other metrics such as cycle time or lead time can also be used to measure output speed.
In some cases, increasing output speed may lead to a decrease in quality or accuracy. It is important to carefully consider the trade-offs and potential consequences before implementing any changes to increase output speed.
No, there are limitations to how much output speed can be increased. Factors such as resources, technology, and human capabilities may place a cap on the potential output speed. It is important to find a balance between efficiency and sustainability.
