• One of the major benefits of a band
brake is the simplicity of the design.
• a band brake assembly is easily
maintained and can work properly for a

• If drum is keptclean and free from rust
then break would work well.

19. A differential band brake is shown in Fig. 12.24(a). The width and
the thickness of the steel band are 100 mm and 3 mm respectively
and the maximum tensile stress in the band is 50 N/mm2. The
coeffi cient of friction between the friction lining and the brake
drum is 0.25.Calculate: (i) the tensions in the band; (ii) the
actuating force; and (iii) the torque capacity of the brake.Find out
whether the brake is self-locking.
