Electromechanical actuator distal position stopping assembly

An electromechanical actuator (EMA) (200) is disclosed. The EMA (200) may comprise an EMA housing (202) having a distal stop (212) that extends radially inward towards a longitudinal axis of the EMA housing (202), a ball nut (204) extending axially within the EMA housing (202), and/or a ball screw (...

Beschreibung
Zusammenfassung:	An electromechanical actuator (EMA) (200) is disclosed. The EMA (200) may comprise an EMA housing (202) having a distal stop (212) that extends radially inward towards a longitudinal axis of the EMA housing (202), a ball nut (204) extending axially within the EMA housing (202), and/or a ball screw (206) extending axially within the ball nut (204). The ball nut (204) may translate axially in a distal direction in response to a rotation by the ball screw (206), and/or the ball nut (204) may be halted in the axially distal translation in response to contact with the distal stop (212). The distal stop (212) may be coupled to the EMA housing (202). The distal stop (212) may comprise a continuous annular structure. The EMA (200) may further comprise a seal (214) located radially inward of a portion of the distal stop (212), which may be in contact with said portion and the ball nut (204) and adapted to prevent debris from entering the EMA (200).
