Calculating Clutch Power Transmission at Speed

Click For Summary

Discussion Overview

The discussion revolves around calculating the power transmitted by a centrifugal clutch at a specific rotational speed, given a coefficient of friction between the clutch shoes and drum. Participants are exploring the necessary formulas and concepts related to clutch power transmission.

Discussion Character

  • Technical explanation
  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant asks how to calculate the power transmitted by a clutch at a particular speed, noting a lack of references in their textbook.
  • Another participant mentions they only have references for disc or conical clutches and questions if these are applicable.
  • A third participant offers help with various types of clutches, including disc, conical, multi-plate, and centrifugal clutches.
  • A later reply specifies the problem involves a centrifugal clutch and provides specific values for speed and coefficient of friction, seeking guidance on the appropriate formula.
  • One participant suggests calculating the torque transmitted due to the frictional force and then using that torque along with the speed to find the power, although they do not have a reference book at hand.
  • Another participant expresses uncertainty about how the coefficient of friction fits into the calculation process.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific formula to use for calculating power transmission, and there is ongoing uncertainty regarding the role of the coefficient of friction in the calculations.

Contextual Notes

Participants have not provided specific assumptions or definitions, and there are unresolved mathematical steps regarding the calculation process.

Hi
How do i calculate the power transmitted by a clutch at a particular speed with a coefficient of friction between the shoes and drum?
I can't find any reference in my textbook.:confused:

Cheers

I can't say that I have any other references than those for disc or conical clutches. Do either of these meet your criteria?
 
I can add to Fred's offer of help with disc, conical, multi-plate and centrifugal clutches...

Thank you :-)

The problem involves a centrifugal clutch

The question is..

Determine the power transmittedby the clutchwhen speed of rotation is600rev/min. Co-efficient of friction is 0.3.

I have values for force and radius, i just don't know what formula to use or how to calculate the power :cry:

Cheers

Without having a book in front of me, I would venture that you calculate the torque that is transmitted due to the frictional force and then use the torque and speed to calculate the power.
 
Coef of friction

Yes i thought that would be the way but, where does the coefficient of friction fit in?
