In the overrunning clutch shown in the illustration, if "A" was rotating faster than "B", the clutch is considered to be __________. See illustration MO-0034.
• How an overrunning (one-way) clutch works when one member turns faster than the other • The difference between driving and driven members in the illustration (A vs B) • What it means mechanically when the rollers/balls are wedged versus when they can roll freely
• Look at the direction of rotation arrows for A and B. If A rotates faster than B in the same direction, would the balls/rollers be wedged tightly or allowed to move freely? • In a one-way clutch, when the outer member overruns the inner member, does torque get transmitted or is the unit freewheeling? • Which of the answer choices describes a normal operating condition of an overrunning clutch, and which describe damage or failure?
• Decide which part (A or B) is intended to be the driving member when torque is transmitted • Visualize where the balls would move if A speeds up relative to B: toward the narrow (wedging) side of the pockets or the wide (free) side • Eliminate choices that describe damage conditions rather than a normal, reversible operating state of this clutch
