Abstract: Actuator assembly includes a housing assembly, a ball screw, a ball nut, and a lock. The ball screw is rotationally mounted on and extends from the housing assembly, is coupled to receive an actuator drive torque, and is configured, upon receipt thereof, to rotate. The ball nut is rotationally supported on the ball screw and is configured, in response to rotation of the ball screw, to translate thereon between a stowed position and a deployed position. The lock is disposed at least partially within the housing assembly and is configured to move between a lock position and an unlock position. The lock prevents the ball nut from translating out of the stowed position when the lock is in the lock position and the ball nut is in the stowed position.

Abstract: Variable bleed valve systems thereof including a stop mechanism with a self-lubricating follower nut assembly are provided. Self-lubricating follower nut assembly includes a follower nut and a pair of grease reservoirs. Follower nut has a recess at each of a first end and a second end and a groove extending between the first and second ends. A grease reservoir is disposed within each recess. Each grease reservoir has an outlet opening substantially aligned with a corresponding end of the groove. Each grease reservoir is compressible to expel lubricating grease into the groove upon compression. The self-lubricating follower nut assembly is configured to translate along a hollow screw between opposed end stops disposed within a housing of the stop mechanism. Each grease reservoir is compressed each time the self-lubricating follower nut assembly impacts an end stop of the opposed end stops.

Abstract translation: 提供了可变放气阀系统，其包括具有自润滑从动螺母组件的止动机构。 自润滑跟随螺母组件包括从动螺母和一对油脂储存器。 从动螺母在第一端和第二端各自具有凹部，在第一和第二端之间延伸有凹槽。 在每个凹槽内设置油脂储存器。 每个油脂储存器具有基本上与槽的对应端对齐的出口开口。 每个油脂储存器可压缩，以便在压缩时将润滑油脂排出到凹槽中。 自润滑从动螺母组件构造成沿着设置在止动机构的壳体内的相对的端部止动块之间的中空螺钉平移。 每次自润滑跟随螺母组件撞击相对的端部挡块的端部挡块时，每个油脂储存器都会被压缩。

Abstract: Actuator assembly includes a housing assembly, a ball screw, a ball nut, and a lock. The ball screw is rotationally mounted on and extends from the housing assembly, is coupled to receive an actuator drive torque, and is configured, upon receipt thereof, to rotate. The ball nut is rotationally supported on the ball screw and is configured, in response to rotation of the ball screw, to translate thereon between a stowed position and a deployed position. The lock is disposed at least partially within the housing assembly and is configured to move between a lock position and an unlock position. The lock prevents the ball nut from translating out of the stowed position when the lock is in the lock position and the ball nut is in the stowed position.
