摘要： An actuator includes M supports to support the rotary shaft, M being an integer equal to or more than 2; and M speed reducers. The Nth support out of the M supports is located at the opposite side of the moving body across the (N−1)th support, N being an integer which is equal to or more than 2 and equal to or less than M. The first speed reducer is connected to the moving body and the first support, receives a movement of the moving body in the axial direction as an input and drives the first support with a reduced drive force that is reduced from the input, and the Nth speed reducer is connected to the (N−1)th support and the Nth support, receives a movement of the (N−1)th support in the axial direction as an input and drives the Nth support with a reduced drive force.

摘要： A ball screw with support devices includes a nut base having two sides equipped with the support devices for preventing the screw from deflection. Two runner structures are provided near two ends of the screw. The runner structure includes a driving wheel and a driven wheel having different diameters and concentrically installed. The nut base is connected to the driving wheel via an active connecting element for driving the driving wheel to rotate. The driven wheel moves with the driving wheel and is connected to the support devices via passive connecting elements so that the support devices and the nut displace synchronously. By controlling a diameter ratio between the driving and driven wheels, the nut and the support devices displace with proportional speeds, thereby allowing the support devices to always stay at the two sides of the nut as designed and provide reliable support.

摘要： A drive cartridge comprises an actuating mechanism, in which a spindle can be guided in a hollow cylindrical drive element between two end positions at an axial distance from one another. The positions are defined by the axial length of the drive element. A dome-shaped casing surrounds the drive element in a non-rotatable and non-displaceable manner. The drive element has an external contour with an eccentric profile and the internal contour of the dome-shaped casing has a positive fit only in those areas of the drive element in which the permissible normal stress exceeds a predefined upper limit.

An inner ring of the supporting bearing is press fit onto the fitting portion via a predetermined interference. A steel spacer ring is fit onto the fitting portion from the outer side of the supporting bearing with the inner side of the inner ring abutted against the shoulder. A caulking portion is formed on the end of the fitting portion by plastically deforming the end of the fitting portion radially outward. The inner ring is axially immovably secured on the screw shaft by the caulking portion via, the spacer ring.

摘要： An improved method and apparatus are provided for constructing and operating a linear actuator, and equipment incorporating a linear actuator, by operatively connecting a pressure biasing pneumatic arrangement between the driving member and the driven member of a mechanical linear actuator for applying a unidirectional biasing force between the driving and driven members, along an axis of motion, regardless of the location or movement of the driving and driven elements with respect to one another along the axis of motion. The pneumatic biasing arrangement is also configured, connected and operated to reduce the force which must be exerted by the driving and driven members in extending and retracting the linear actuator. The pneumatic biasing arrangement may further be configured for preferentially aiding extension or retraction of the actuator.

摘要： A linear unit (1) comprising a profiled rail (2) along which a carriage (3) is arranged for sliding motion backwards and forwards by means of a reversible screw (4) which actuates the carriage and on either side of the carriage passes through a bore (7) in a screw support (8). A pull rod (24) displaces the screw support backwards and forwards along the profiled rail between to end stop positions, and the screw support serves as a support bearing carrying the screw between bearings (10) supporting the screw at its ends. A self-centering device for automatic centering of the screw in the screw support is formed with a self-centering element (11) mounted in the screw-support bore, said element slidingly abutting against the screw both when the screw is rotating in either one of its directions of rotation and when the screw support assumes its end stop positions. The pull rod kinetically interconnects the screw supports located on either side of the carriage, whereby as the carriage is displaced in a sliding motion in one direction it will abut against the screw support located on one side of the carriage for displacement of said screw support from one of its end stop positions to the other one while simultaneously, via the pull rod, bringing along in its movement the screw support located on the other side of the carriage, and reversely.
