Embodiment Construction

[0054] exist Figure 1 to Figure 3 In , the actuator separator embodying the first embodiment is generally indicated by the numeral 10 . like Figure 1 to Figure 3 As shown, the example actuator decoupler 10 includes an example sleeve member 12 , an example housing member 14 , an example cam plate 16 , an example cam plate cover 18 , and an example coupling pin 20 . The example actuator decoupler 10 is configured to at least partially selectively couple a power source (not shown) and a load receiver (not shown), as explained further below. Thus, in the coupled state, the actuator disconnect 10 is used to engage the drive part 30A (ie, the power source and associated components) with the driven part 30B (see Image 6 and Figure 22 ) so that they are fixed relative to each other in at least one of rotational or angular and longitudinal or axial directions, and, in the disengaged state, the actuator separator 10 is used to connect the driven part 30B with the driving part 30A ...

Abstract

The invention relates to a jam tolerant actuator decoupler, and discloses an actuator decoupler for selectively coupling and decoupling a driving part and a driven part of an actuation system is disclosed. The driving part can be coupled to the actuator decoupler, and the actuator decoupler can be coupled to the driven part via at least one coupling pin. In a selectively coupled state, the driven part can be at least one of rotationally and longitudinally fixed to the actuator decoupler and, thereby, the driving part. The actuator decoupler can be decoupled from the driven part through the use of a preloaded energy mechanism configured to disengage the at least one coupling pin from the driven part 30B. Thereby, the actuator may be responsive to a jam in the actuation system to selectively decouple the driven part from the actuator decoupler and the driving part so that the driven part has freedom to translate at least one of rotationally and longitudinally.

Description

technical field [0001] The present invention relates to jam tolerant actuator separators. Background technique [0002] Actuators are widely used in many industries to control the movement of various components. Some actuators are configured to transfer rotational energy between components to ultimately effect movement of a surface or component. Similarly, some actuators are configured to transfer linear properties between components to ultimately effect movement of surfaces or components. Additionally, some actuators are configured to transfer both rotational and linear energy between components to ultimately effect movement of a surface or component. [0003] Some actuator applications require reliable, trouble-free or fail-safe mechanical or electromechanical actuators. More specifically, many applications require actuators that include a mechanism that limits the input force during a fault condition, such as when a component of the actuation system in which the actuat...
