Friction Clutches, Brakes, Belt Drives and Chain Drives topics include: Friction clutches, cone clutches, centrifugal clutches, brakes, block brakes, expanding brakes, belt drives and constructions, chain drives and its design. Friction clutches, brakes, belt drives, and chain drives are mechanical components that transmit power and motion.  Friction clutches: These clutches use friction between surfaces to transmit torque and power between two rotating shafts. The surfaces are lined with materials like cork or asbestos. Friction clutches are used in many applications, including... Show more
