摘要： A vehicle power transmitting device can include a clutch and an actuator. The actuator can include a coil spring, a plunger, and a rotating member. The coil spring can include a plurality of coils disposed about an axis. The plunger can include a body and a follower. The follower can be fixedly coupled to the body. The body can be disposed about the axis and coupled to the clutch to selectively activate the clutch. The follower can be received between adjacent ones of the coils. The rotating member can be rotatable about the axis and drivingly coupled to one of the coil spring and the plunger to rotate the one of the coil spring and the plunger about the axis. Rotation of the rotatable member can effect translation of the plunger, compression of the coil spring, or both translation of the plunger and compression of the coil spring.

摘要： A system and method for propelling a hose, including: a system housing and a tractor element disposed in the housing. The tractor element includes: a tractor housing with a through-bore; and a protrusion extending into the through-bore. The system includes: a hose assembly including a substantially helical coil disposed about a hose; and an actuator for rotating the tractor housing with respect to the system housing. The tractor element is fixed in the system housing with respect to axial movement; and the hose assembly can be disposed in the through-bore so that the protrusion contacts a portion of the coil. As the tractor housing is rotated in a rotational direction: the protrusion exerts a displacement force on the coil; and the hose assembly reacts to the displacement force by displacing in an axial direction.

摘要： A position sensing assembly includes a bearing element and a helically shaped rotational member used to drive a portion of a sensor assembly, such as a Digital Rotary Magnetic Encoder. Interaction between the bearing element and a helically shaped rotational member minimizes the presence of backlash in the position sensing assembly. Accordingly, as an actuator assembly drives both a control element, such as a flight control surface, and the position sensing assembly, the sensor assembly generates an output signal that accurately reflects the position of the control element.

摘要： A ball screw apparatus includes a cylindrical screw shaft having a spiral groove in an outside peripheral surface, a cylindrical ball nut surrounding the screw shaft and having a spiral groove in an inside peripheral surface, and a plurality of bearing balls rotatably interposed the two spiral grooves, which are aligned and spaced apart such that the bearing balls are free to rotate as the ball nut rotates about and moves along the screw shaft. One or more of the screw shaft and the ball nut may include a spiral wire coil and a coil shape retention device. The opposed peripheral surfaces of adjacent coils of each spiral wire coil form the walls of one of the spiral grooves. Each coil shape retention device prevents the associated spiral wire coil from changing shape when the ball nut moves spirally relative to the screw shaft.

摘要： A nut unit (20) for use in a ball screw drive comprises a sleeve-shaped nut body (10) that is made of an essentially rigid material and that has an axis (A) and an inner circumferential surface (14). A one-piece, channel-shaped, ball-guiding strip material helix (18) is arranged on the inner circumferential surface (14) of the nut body (10). The strip material helix (18) is mounted within a concavely-curved support groove (16) formed in the inner circumferential surface (14) of the nut body (10). The helix (18) has an external convexly-curved profile (46), which is embodied with external profile flank regions (46′) and an external profile crown region (46″). The helix (18) defines, by means of a curved internal profile (48) facing the axis (A), a ball channel with an internal profile base region (48″) and two internal profile flank regions (48′). The outer profile flank regions are essentially rigidly supported by the support profile of the support groove (16).

摘要： A variable pitch screw driver system includes a rotatable drive nut powered by a motor actuator. A base screw having a fixed pitch extends through the drive nut and is linearly translatable in response to rotation of the drive nut. The base screw carries a pin that follows a secondary helical screw. Linear translation of the base screw is altered by tracking of the pin along the helical screw such that rotation of the base screw is selectively effected simultaneously with rotation of the drive nut resulting in an effective variable pitch of the screw driver. Linear translation of the base screw effects linear translation of a piston at a variable rate.

摘要： In a feed screw device according to the present invention, a coil member is disposed on the outer periphery of a rotary shaft member. The coil member is formed of an elastic body such as a piece of piano wire. The coil member is mounted at least partially on the shaft member so as to have at least a portion remaining in a free state. The coil member is used to engage a nut placed on the outer periphery of the shaft member. When the shaft member is rotated, the coil member is also rotated together with the shaft member, so that the nut is moved in the axial direction of the feed screw. When the nut is brought into contact with a stopper by a driving force, the nut impactively strikes the stopper. However, since the coil member can be elastically deformed in the axial direction, the coil member is elastically deformed to absorb its impact. Also the "spring back" effect enabled by the deformable coil member serves as a contribution to the initiation of movement of the nut in the reverse direction. Thus, when the direction of the driving force is reversed, the nut can immediately be moved in the reverse direction by a slight driving force.

摘要： A motion conversion mechanism comprising a threaded shaft and a nut, is disclosed. The nut comprises a cylindrical body having the inner surface thereof formed with a groove corresponding to the thread of the threaded shaft. A string having a low friction property surface is fitted in the groove such that it partly projects from the inner peripheral surface of the cylindrical body. The projecting portion of the string constitutes a thread to be screwed with the thread of the threaded shaft.

摘要： A screw-nut screw coupling comprises a tubular element provided with an internal helical groove and an elongate member, formed by a preloaded spring having an external helical groove machined thereon. The tubular element is coupled to the elongate member by means of a number of balls mounted for rolling along an helical path defined by said helical grooves and forming a portion of an endless path for said balls to roll therealong. The tubular element is formed by at least two co-axial tubular sleeves rigidly connected to one another, one of said sleeves being arranged outside the other and being provided with groove means defining a portion of said endless path.
