    摘要： The present invention is related to a fixing and actuating mechanism with a spiral ball channel which is designed as the square and trapezoidal screws or rectangular or particularly coiled springs in different shapes which are produced in the sensitivity that can work in the system to perform the function of converting rotational movement into linear movement similar to the relationship of a screw and square nut and is performing while eliminating the friction between the surfaces to add new functions that the like cannot perform.

    摘要： The actuator locking mechanism is a bi-directional secondary load path lock that operates under both compression and tension loads via a radial locking wedge and axial slide lock system. This locking mechanism is designed to effectively protect against structural disconnect after a primary load path failure occurs and to minimize the axial play in the engaged secondary load path. To avoid the dormancy of such a failure, the activated mechanism jams/stalls the actuator drive thereby alerting the aircrew and the maintenance crew of the fault condition and allowing safe continued flight and landing. This locking mechanism is impervious to relative deflection between the primary and secondary load path such that under a non-failed condition, the mechanism will not jam. A jam only occurs when axial displacement (tension or compression direction) is greater than a predetermined relative deflection. This axial displacement is eliminated by the slide locking system minimizing the axial play. The makeup of this radial locking design also features a cageless roller implementation which captures the rollers within the features of the V-shaped ramp design.

    摘要： A linear actuator using a screw mechanism is provided which can be made free from play and can operate in a smooth fashion without involving any unacceptably rigorous tolerance control. An external thread of a screw rod is in threading engagement with an internal thread of a nut member for converting a rotational movement of the nut member into a linear movement of the screw rod, and a localized region of relatively tight fit is provided in the threading engagement. In particular, when the nut member is made of a molded plastic member, the localized region of relatively tight fit can be easily formed by grinding or cutting a part of the molding core for molding the internal thread of the nut member.
