Design a centrifugal clutch for a belt drive from a shunt wound dc motor. The clutch is to be incorporated in the motor pulley and full spring control is required. The following data are specified. | Power $(25 \%$ over load to be allowed $)$ | $=15 \mathrm{kw}$ | | :--- | :--- | | Speed | $=720 \mathrm{rpm}$ | Engagement to begin at $75 \%$ of running speed | Number of shoes | $=4$ | | :--- | :--- | | Outside diameter of Pulley | $=35 \mathrm{~cm}$ | | Inside diameter of pulley rim | $=32.5 \mathrm{~cm}$ | | Width of pulley | $=25 \mathrm{~cm}$ | | Spring type | = flat, rectangular section | Initial clearance between friction surfaces, when linings were new $\quad=1.6 \mathrm{~mm}$
Explanation
The centrifugal clutch is designed to engage at a speed of 75% of the running speed. The power transmitted by the clutch is calculated based on the centrifugal force acting on each shoe and the spring force. The spring constant is calculated based on the equilibrium condition. The power transmitted by the clutch is calculated based on the torque transmitted by the clutch.
