Description of FRB750 Sprag Clutch as overrunning and backstop with a ball bearing supported
FRB clutch is a high speed, centrifugal throw-out (C/T) Sprag design, supported by sealed ball bearings. The C/T Sprags are designed to "lift-off" from the races during high speed inner race overrunning.
In this design, the center of mass of the Sprag is located so that when the inner race is overrunning, the centrifugal force of the Sprag overcomes the force of the energizing springs causing the Sprags to completely "pull away" from the races.
The advantage of using C/T Sprags is that, when overrunning at above the lift off speed, there is no contact between the Sprags and the races so there is no wear (for a longer operating life), no heat being generated (the clutch runs cooler), no Sprag drag so the resistance after run-in is lower. With sealed bearing this design is almost virtually maintenance free.
