One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.
The addition of three gears was facilitated by adding a "selectable one-way clutch" which can act either as a sprag clutch, freewheeling in one direction and locking up in the other, or freewheeling in both directions.
While this occurs, the intermediate turbine receives an ever increasing share of the energy from the pump, as the Low turbine moves faster and oil passes more freely through it. Eventually, the low turbine matches pump speed, and the low turbine freewheels on a one-way sprag clutch much like on a bicycle. At this point, the intermediate turbine ...
A one-way sprag clutch is built into the center of the upper sheave to allow the rotor system to continue to rotate in the event of engine failure, allowing the R22 to enter autorotation and land in a controlled manner. Because the main rotor has very little mass and inertia, autorotation in an R22 requires careful and proper execution to ...
The electronically controlled transmission is designed around a fully articulated Ravigneaux planetary gearset that is controlled by electronically timed application of several range-specific hydraulic clutches, in combination with mechanical one-way sprag clutches.
