    摘要： A linear actuator (100) arranged to convert rotary motion to linear motion is disclosed. The linear actuator includes a linear shaft arrangement, having a first shaft portion (110) and a second shaft portion (130) and extends along a longitudinal axis (A) of the linear actuator. At least one of the first shaft portion and the second shaft portion of the linear shaft arrangement can be translated linearly along the longitudinal axis upon actuation. A first drive system has a first rotary component (106) extending at least partially around the longitudinal axis. A second drive system has a second rotary component (126) extending at least partially around the longitudinal axis at a different axial position to the first drive system. The linear actuator, when the first drive system fails, allows rotation of the second rotary component so that the second shaft portion moves relative to the first shaft portion.

    摘要： A drive arrangement in a pneumatic power tool includes a pneumatic motor with an output shaft, and a spindle for mounting a cutting element and which externally includes both a thread and an axial groove. A drive rotation of the spindle is driven by a drive gear that is engaged with the axial groove on the spindle and that is drivingly connected to the output shaft so as to rotate at a constant speed with respect to the output shaft. A feed gear is threaded upon the spindle and may be rotated with respect to the spindle in order to advance and retract the spindle. The feed gear is driven by one intermediate feed gear which is interchangeably drivingly connectable to the output shaft via a first and a second gear connection, respectively, so as to advance or retract the spindle.

    摘要： The linear actuator comprises an output shaft (4) having a pair of driven wheels (6, 8), one (8) being rotatable thereon in a fixed plane and having a drive nut (9) for an associated thread (11) on said output shaft and the other (6) being rotatably fixed (6A) to said output shaft, an input shaft (2) alongside the output shaft which is rotated by a suitable power source (3) and a drive wheel (5, 7) for each driven wheel rotatably fixed on said input shaft, the ratio between each drive and driven wheel set being chosen to rotate the driven wheels at different speeds in the same rotational direction to produce axial movement of said output shaft in a direction depending upon relative rotation of the driven wheels. In accordance with the invention the fixed driven wheel (6) and drive wheel (5) are meshing helical gear wheels, and a fail-safe arrangement is provided comprising a clutch (27, 29) between the drive wheels (5, 7) of the input shaft, a back-drive (9, 11) for said output shaft, and biasing means (22) for effecting a back-drive. In operation the meshing helical gears impart an axial force to engage the clutch only while power is supplied, the biasing means being operative to back-drive the output shaft to a fail-safe position when the power is terminated. The actuator can be readily modified to be operated by a remote operating vehicle (ROV) in undersea applications.

    摘要： Die Erfindung betrifft ein Werkzeugtreiberaggregat, insbesondere für den Antrieb von Transportwerkzeugen, umfassend ein Linearstellglied (12) mit einem in einem Gehäuse (18) gelagerten, eine Drehachse (D) festlegenden Aktuator (14), der durch eine erste Drehantriebseinrichtung (16, 20) angetrieben und relativ zu dieser in Axialrichtung verstellbar ist, wobei das Aggregat ferner eine zweite Drehantriebseinrichtung (24, 26, 28) aufweist, die derart auf den Aktuator (14) wirkt, dass die axiale Verstellung oder/und eine Drehung des Aktuators (14) relativ zu den beiden Drehantriebseinrichtungen (16, 20; 26, 28) abhängig von einer jeweiligen Drehzahl der beiden Drehantriebseinrichtungen (16, 20; 26, 28) einstellbar ist, und wobeidie zweite Drehantriebseinrichtung (26, 28) eine Welle (22) antreibt, welche mit dem Aktuator (14) in gemeinsame Drehung um die Drehachse (D) versetzt werden kann und gemeinsam relativ zu den beiden Drehantriebseinrichtungen (16, 20; 26, 28) axial verstellbar ist. Erfindungsgemäß ist dabei vorgesehen, dass das Aggregat zur Begrenzung der Drehung mechanische Anschlagmittel (52, 58) umfasst.
