    • 专利摘要:
    A spindle nut (12) is located in the wormgear (10), which is supported in a supporting body (1) such that it can move only rotationally, is guided such that it can move only in a translatory manner and is supported at both ends on the wormgear by means of spring arrangements (14, 15). A threaded drive spindle (3), coupled to the spindle nut (12), is guided on the supporting body (1) such that it can move only in a translatory manner and, between it and a control spindle (6), which is supported only in a movable manner, of a control element (5) connected to the supporting body (1), there is provided a buffer arrangement (3A, 4, 16, 17, 18) acting in a sprung force-fitting manner as a control force device. <IMAGE>

    Claims (8)
    [1]
    Claim
    1. An electric actuator with a sliding cascade for rectilinear movement of the executive link, comprising an electric motor, a housing, a worm gear, the worm of which is designed to be connected to an electric motor, a uterine nut connected to the worm wheel, and a sliding cascade made in the form of a lead screw fixed from rotation, the intermediate part connected to it, the connecting element, two coaxial thrust discs designed to interact with two pairs of stops, the first pair of which x is fixed on the connecting element, and the second on the intermediate part, and the distance from the axis of the connecting element to the first pair of stops is less than the distance to the second pair of stops, and the package of Belleville springs located between the stop discs, the actuator, including the rod, and the fifth emphasis restricting the stroke of the executive link, characterized in that, in order to increase reliability by providing the same clamping force of the executive link, it is equipped with a sixth emphasis designed to limit movement eniya lead screw, and turn the screw shaft is greater than the stroke actuator in the respective end position.
    [2]
    2. Drive pop. 1, characterized in that it is equipped with a seventh stop rigidly connected with the housing, designed to limit the movement of the screw in the opposite direction.
    [3]
    3. The drive according to paragraphs. 1 and 2, characterized in that it is provided with two additional springs located at the respective ends of the worm wheel and designed to tighten the master nut to the worm wheel, and the master nut is mounted in relation to the worm color with axial movement and fixed against rotation.
    [4]
    4. The drive on PP. 1-3, due to the fact that the intermediate part is made in the form of a glass, the drive is equipped with a pin fixed to the connecting element with a threaded hole, in which the rod with the corresponding thread is located, and the connecting element is placed in glass and fixed against rotation.
    [5]
    5. The drive according to paragraphs. 1-4, characterized in that the housing is made along the length of two parts forming a closed cavity designed to be filled with oil, in one part of the housing there are two seals for the corresponding ends of the worm, and in the second part there is a third seal designed for the journal connecting element.
    [6]
    6. The drive according to paragraphs. 1-5, characterized in that the seventh emphasis is mounted to move and lock along the axis of the screw.
    [7]
    7. The drive according to paragraphs. 1-6, characterized in that the seventh stop is made in the form of a screw, the drive is provided with a cover forming a closed cavity with a housing in which the screw is placed, and two channels are made in the housing connecting the closed cavity with the housing cavity.
    [8]
    8. The drive according to paragraphs. 1-7, characterized in that the sixth stop is formed by a part of the housing in which the journal of the connecting element is located.
