    摘要: A unit drive assembly (2) is used with postage meters (4) of the type which include a stationary base (6) and moveable print head (8). The base (6) and print head (8) are mechanically connected so that input information to the base (6) is mechanically transmitted to the print head (8). The assembly (2) includes one or more drive tracks (10) along which a series of balls (16) are positioned. A first portion (12) of the drive track (10) is carried by the base (6) while a second portion (14) is carried by the head (8). The first (12) and second (14) portions are aligned when the head (8) is in the home position; it is at this time a ball drive (28) carried by the base (6), moves the balls (16) along the track (10) discrete distances equal to one or more ball (16) diameters. The head (8) includes one or more print wheels (36) driven by the balls (16) positioned along the second portion (14) of the track (10) so that the distances the print wheels (36) rotate, which determines the value to be printed, depend upon the distances the balls (16) are driven along the tracks (10).

    摘要: A device is composed of relatively rotatable cylindrical components (1, 2) one of which has a groove forming a raceway or track (4) of part-helical form containing a set of balls (3) in contact with a plain surface of the other component. The raceway (4) wedges with the balls (3) to resist direct axial motion between the components (1, 2). Rotation of one component (1, 2) causes the balls (3) to move around the raceway (4) and be guided from the end to the start thereof under sufficient traction to cause linear motion of the other component (2, 1).

    摘要: Actionneur linéaire (1) comprenant un boîtier (6), un moteur (2) comprenant un stator avec des bobines (4), un système vis-écrou, et un rotor (5) supporté axialement et radialement côté moteur par un palier (11). Le palier comprend une bille (14) fixée rigidement au rotor, une cavité cylindrique (15) formée ou disposée dans le boîtier dans lequel la bille (14) est insérée. Une butée (17) est disposée dans la cavité en appui dans une direction axiale du rotor, contre la bille (14) en essentiellement un point.

    摘要: A shaft support (10), which supports both end portions of an elongated screw shaft (12) for use in moving a movable element, such as an arm of an industrial robot in a predetermined direction, is fixed to the upper surface of a base plate (14) via a gear box (30) which supports a driving motor (22) and the elongated screw shaft (12), and which contains reduction gears (24) therein, in such a manner that a projected area of the shaft support (10) on a plane perpendicular to the longitudinal direction of the elongated screw shaft (12) is reduced. When the gear box (30) is fixed to the base plate (14), a circular boss (32b), which is provided on the lower surface of the gear box (30) for use in positioning the gear box (30) in the plane of the base plate (14), and a bore (14a) provided in the base plate (14) are used. The vertical positioning of the gear box (30) is done by a positioning member (40) having a predetermined height.
