A fluid power linear drive device comprises a housing tube on whose outer periphery an output drive slide can slide linearly. For this purpose on the outer periphery of the housing tube there are two guide face pairs each having two guide faces extending along the housing tube on the outer periphery of the housing and, in the axial is direction of a first transverse axis of the housing tube, opposite each other, which in the direction of a second transverse axis, perpendicular to the first transverse axis, are spaced apart. The guide faces, as considered in a cross section of the housing tube, are slanted in each case in relation to the first and second transverse axis, first bearing elements arranged on the output drive slide are engaging the guide faces of the one, first guide face pair, such first bearing elements being able to pivot in relation to a pivot axis extending in the longitudinal direction of the housing tube independently of each other in relation to the output drive slide, and the guide faces of the other, second guide face pair are engaged by second bearing elements arranged of the output drive slide, the transverse position of the second bearing elements assumed in the axial direction of the first transverse axis in relation to the output drive slide being able to be varied.

Fluid power linear drive device

A piston rod-less linear drive () has a housing () with a longitudinal slot () having a moving force coupling member extending through it. The outer slot opening () is provided with at least one covering band (), which is fixed at an attachment section () on a longitudinal side () of the outer slot opening (). The covering band ( )) furthermore has a pivoting covering section (), which is provided with detent means (), which render possible a releasable detent function in a covering position covering the outer slot opening. Actuating means kinematically coupled with the force coupling member may act on the covering band in order to cause the detent locking action.

Linear drive with no connecting rod

A piston-rod-less linear drive ( ) whose housing ( ) possesses a tube body ( ) with housing covers ( ) mounted at terminal sides. The tube body ( ) is provided with a longitudinal slot ( ) which is covered over by an internal and/or outer closure band ( and ). For securing the terminal band sections ( and ) and securing means ( ) are provided, which comprises a support body ( ) arranged on the respective terminal band section ( and ), such support body ( ) projecting laterally past the outline of the closure bands ( and ) and bearing independently from the housing cover ( ), provided on the same terminal side, on the associated terminal face ( ) of the tube body ( ).

Rodless linear drive

A piston rod-less linear drive whose housing is provided with a linear guide on which a guide slide runs. The guide slide is drivingly connected by way of a dog with a drive part within the housing. The dog extends through a longitudinal slot in the housing, such slot being so arranged that its plane extends obliquely in relation to a guide plane, which is defined by the longitudinal direction and the transverse direction of the linear guide. Furthermore, a housing is proposed which is particularly suitable for the linear drive.

Piston rod-less linear drive and a housing therefor

A drive and guide means for a load to be moved which comprises a rodless drive piston adapted to be driven by a pressure medium in a pressure medium cylinder, such piston having at least one force transmission part extending outward through a longitudinal slot in a wall of such cylinder. A flexible sealing tape for seals off the longitudinal slot on either side of the force transmission part. An anti-friction bearing arrangement serves to take up a load and/or to guide the piston, such anti-friction bearing arrangement being arranged in the housing of the pressure medium cylinder. An anti-friction bearing arrangement is arranged within the cylinder space of the pressure medium cylinder in or on the drive piston. This means that pressure medium cylinders with an extremely small cross section and an extremely simple structure may be produced economically.
