One-way clutch for use in a no-back clutch design

An actuator, comprising:

• an input shaft comprising a central shaft portion and a screw flange extending radially outwardly from the central shaft portion;
• an output shaft;
• a friction plate affixed to the output shaft;
• a one-way clutch comprising an inner diameter portion affixed to the central shaft portion, an outer diameter portion and a one-way clutch portion interposed between the inner and output diameter portions;
• and
• a bearing disposed between the screw flange and the outer diameter portion such that a compressive load path is formed from the screw flange, through the bearing and the outer diameter portion and to the friction plate and the output shaft,
• the one-way clutch portion being configured for free-wheeling during forward rotation of the input shaft to thereby permit rotation of the input shaft in the forward direction to be transmitted to the output shaft and for jamming during reverse rotation of the input shaft to create a drag event on the friction plate to thereby inhibit rotation of the input shaft in the reverse direction to be transmitted to the output shaft.

An actuator of an electric powered nacelle door opening system (PDOS) comprising a nacelle door of an aircraft engine, the actuator comprising:

• an input shaft comprising a central shaft portion and a screw flange extending radially outwardly from the central shaft portion;
• an output shaft coupled to the nacelle door;
• a friction plate affixed to the output shaft;
• a one-way clutch comprising an inner diameter portion affixed to the central shaft portion, an outer diameter portion and a one-way clutch portion interposed between the inner and output diameter portions;
• and
• a bearing disposed between the screw flange and the outer diameter portion such that a compressive load path is formed from the screw flange, through the bearing and the outer diameter portion and to the friction plate and the output shaft,
• the one-way clutch portion being configured for free-wheeling during forward rotation of the input shaft to thereby permit rotation of the input shaft in the forward direction to be transmitted to the output shaft and for jamming during reverse rotation of the input shaft to create a drag event on the friction plate to thereby inhibit rotation of the input shaft in the reverse direction to be transmitted to the output shaft.
