Please take a 2-minute survey to help us know how we can offer more models like this! https://goo.gl/forms/MiyWYwno927Wb4TH2 Overrunning clutches, also known as freewheel clutches, are used in applications where torque is transmitted in only one direction. They have been traditionally used in vehicle transmissions, engine starters, agricultural equipment, helicopters, and bicycles. There are several variations of overrunning clutches, but the four main types include sprag clutches, roller or ball clutches, spring clutches, and ratchet and pawl clutches. The design most resembles the ratchet and pawl clutch, which was produced by the Compliant Mechanisms Research Group at Brigham Young University under the direction of Dr. Larry Howell. https://www.compliantmechanisms.byu.edu/ Advantages of using a compliant overrunning clutch include lower part count than alternative designs, easy assembly and maintenance, reduced part wear, low cost, simplicity, less lubrication required. Disadvantages include difficult manufacturing due to very thin segments, requires non-linear analysis methods, noisy when clutch teeth are passively rotating past compliant parts. https://youtu.be/KbHqf4kF5Wk
