Calculating Spring Force for a Multi Plate Clutch

AI Thread Summary
To calculate the spring force required for a multi-plate clutch with four frictional surfaces, the internal diameter is 120mm and the external diameter is 200mm, with a coefficient of friction of 0.3. The goal is to transmit 20KW of power at 1440 RPM under uniform pressure conditions. Initial calculations suggest a spring force of 1381.597N, while another method indicates a required force of 1841N after converting power to torque. The discrepancy in results highlights the importance of verifying calculations and assumptions in clutch design. Accurate calculations are crucial for ensuring effective clutch performance.

A multi plate clutch has 4 frictional surfaces, imternal diameter 120mm and external diameter 200mm. The coefficent of friction is 0.3

What spring force will be required to transmit 20KW of power at 1440 RPM if the clutch is under uniform pressure conditions?

Using constant wear therory R1 + R2 / 2

I have managed to reach an answer of 1381.597N or 1.381KN (Can anyone confirm please?)

Thanks,
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
