The Brake Drum Friction Apparatus (DN – 011) is a benchtop brake drum apparatus with single leading and trailing shoe. The apparatus provides drum torque and braking load applied by weight hangers and cords.
- An aluminum brake drum is secured to one end of a sturdy bench top mounted base.
- The drum has an external cord grooved and its inside face is machined to plain aluminum.
- A cord is wrapped around the perimeter of the brake drum and the free end of the cord runs over a pulley at the other end of the base and terminates with a load hanger.
- Torque is applied to the brake drum by using the calibrated weights set provided and the load hanger.
- Mounted inside the brake drum is a single brake shoe with its own pivot.
- A second cord connects to the brake shoe and again runs over a pulley and terminates at the load hanger.
- As the load is applied to the brake shoe so that friction force increases.
- Load must be added to the torque hanger, then try and rotate the brake drum at near constant speed.
- The sense of rotation of the torque determines whether the single brake shoe acts as a leading or trailing shoe.
- Direct comparison of tangential force and braking load is obtained and the coefficient of friction determined.
