摘要： A linear bearing with revolving roller elements has a carrier body on which a closed track is formed, the runner elements moving on this track, which comprises a load track, a return track, and two substantially U-shaped roller element deflection tracks. Lateral guide means are provided for the roller elements: the guide means have homogeneous lateral guide walls for the roller elements and are formed to be step-free and continuous over the length of the load track and over at least part of the adjacent deflection tracks.

摘要： A mechanical linear drive system for generating a defined linear movement of a driven force transfer element (16) has a spindle drive, the threaded spindle (7) of which is supported in a profiled tubular structure (1) of stable shape, closed off at the end by bearing flanges (9) and provided with a linear slit through which the force transfer element, drivingly coupled in the longitudinal direction of the tubular structure by the spindle nut (11) of the spindle drive, protrudes to the outside out of the tubular structure. To permit adaptation to conditions imposed by various kinds of use, the arrangement is such that the spindle nut is supported rotatably and axially immovably on the force transfer element, and that a drive means that is joined with the force transfer element is coupled with the spindle nut (11) via a gearing means (18, 19, 20) located on the force transfer element (16). This drive means, and a further drive means (10) that may be provided for driving the threaded spindle, makes it possible to generate the most varied kinds of linear movements. A plurality of spindle nuts can also be provided on the threaded spindle, or the threaded spindle can be divided into a plurality of spindle portions.

摘要： A linear motion transfer apparatus has a longitudinally slit elongated tubular structure (1) closed at its ends, in which a force accepting element (4) driven in the axial direction is guided in a longitudinally displaceable manner, and the longitudinal slit (10) of which is sealed off at both ends of the force accepting element by an inner flexible sealing element (27), which is guided underneath a force transfer element (11) protruding to the outside through the longitudinal slit and connected to the force accepting element (11), and with which a flexible covering element (30) is associated. The force transfer element (11) is longitudinally guided, by means of a ball-like guide element (17) partially encompassing the tubular structure (10), on at least two parallel guide tracks (16), which are disposed on both sides of the longitudinal slit (10) directly on the outside of the tubular structure (1). In order to prevent uneven loading, especially of the force accepting element, caused by tolerances, the arrangement is such that the force accepting element (4) is coupled to the guide element (17) at least one bearing (18) in such a manner that limited movement is permitted.

摘要： To provide for effective sealing of a movable piston in a cylinder formed with a longitudinal slit, a motion transfer element (9, 10, 11, 12) is coupled to the piston (5) extending through the slit (3) and shaped in form of a yoke (11) extending over and around the outer surfaces of the cylinder tube (1), to retain the portions of the tube separated by the slit. The slit is sealed in the region between sealed ends (4) of the cylinder and the piston heads (6, 7) of the piston by a pair of separable and re-engageable plastic strips (18, 27), the inner strip (18) being formed with a projecting headed ridge (26) fitting in a snap-in groove (30) defined by two legs (29) extending from the outer strip. Upon movement of the piston (5), a wedge-shaped separating element (36) separates the interengaged ridge-groove combination ahead of the movement, and a top pressing element (37) coupled to the yoke (11) re-seals the headed ridge (26) in the groove (30) at the trailing side to form sealed cylinder chambers (19, 20) and retain the cylinder chambers in sealed condition upon movement of the piston, and with it the yoke and the separating wedge. The strips may be made of plastic to permit resilient deflection and engagement of the ridge (26) in the groove (30).
