Definitions

  • the invention relates to a pressure-actuated working cylinder with a driver driven by a piston via a flexible tension element according to the preamble of claim 1.
  • Such a cylinder is known from DE-OS 28 30 058.
  • This known working cylinder has guide plates attached to the cylinder housing, each for a deflection device having a deflection element for the tension element.
  • the deflecting elements are designed as deflecting rollers, the deflecting rollers being arranged in the region of the ends of the cylinder housing.
  • Each deflection roller is arranged on an axis that runs transversely to the longitudinal axis of the cylinder housing and serves as a support for the deflection roller, which is slidably mounted in a slot-shaped recess of this guide plate that runs parallel to the longitudinal axis of the guide plate in the longitudinal direction of the slot-shaped recess.
  • Spring-loaded means are provided, which are supported on the guide plate and load the axis in the direction away from the cylinder, so that the tension element is always kept under tension.
  • the invention has for its object to provide a pressure-actuated working cylinder of the type mentioned, which is compact in its construction and in which a safe guidance of the deflection device and thus the tension element is guaranteed.
  • the invention offers in particular the advantage of being able to form the working cylinder in a space-saving manner by the arrangement of supports for the deflecting elements which are slidably guided in a further housing bore additionally provided in the cylinder housing.
  • each carrier is at least partially designed as a tubular body, into which a spring that acts on the carrier from the cylinder housing extends. This measure considerably reduces the space required for a spring with a large axial extension.
  • an anti-rotation device for the carrier and thus also for the deflection roller is achieved without an additional anti-rotation device having to be provided for this purpose.
  • This anti-rotation device ensures that the tension element is guided securely by means of the deflection element.
  • an anti-rotation device can be achieved by providing a groove running in the longitudinal direction of the housing bore in the wall defining the housing bore, into which a projection provided on the carrier engages.
  • a common housing bore can be provided for both supports, which is divided into two coaxial housing bore parts by an insert.
  • a pressure-actuated working cylinder is shown with a driver driven by a piston via a bendable tension element.
  • the working cylinder has a profile tube serving as a cylinder housing (1), with a tube in the longitudinal direction axis of the cylinder housing (1) extending first housing bore (34).
  • the first housing bore (34) can have a circular cross section, but also a cross section that deviates from the circular shape, for example an oval cross section.
  • a piston (31) is arranged so as to be displaceable and sealed by means of sealing rings (30) and (32).
  • the cross-sectional shape of the piston (31) naturally corresponds to the cross-sectional shape of the first housing bore (34).
  • the first housing bore (34) is closed at both ends by a first cover (2) and a second cover (27).
  • the piston (31) divides the cylinder space into a first working chamber (33) and a second working chamber (29).
  • the first working chamber (33) is connected via a pressure medium connection (35) and the second working chamber (29) is connected via a second pressure medium connection (28) to a valve device, not shown, via which the two working chambers (33) and (29) optionally with one Pressure medium source or with the atmosphere or with a return line.
  • first cover (2) there is a passage with a sealing element (3) and in the second cover (27) there is another passage with a sealing element (26) through which a pulling element (25) connected to the piston (31) seals the front of the cylinder is led out.
  • a first guide (12) is provided in or on the cylinder housing (1) for a driver (14) guided in the longitudinal direction of the cylinder housing (1).
  • the cylinder housing (1) has a further guide, which is formed in each case by a further housing bore (13) or (16) of the cylinder housing (1), which runs in the direction of the longitudinal axis of the cylinder housing (1).
  • the two other housing bores (13, 16) have a rectangular cross section.
  • the two further housing bores (13) and (16) are formed by a bore penetrating the cylinder housing (1) in the longitudinal direction, which is divided into the two housing bores (13) and (16) by an insert (15) arranged in this bore is.
  • One housing bore (13) is referred to below as the first bore section (13) and the other housing bore (16) is referred to below as the second bore section (16).
  • the further guide is arranged in the area between the first housing bore (34) and the first guide (12) provided in or on the cylinder housing (1) for the driver (14), which is also connected to the tension element (25).
  • the longitudinal axis of the first housing bore (34), the longitudinal axis of the further guide (13, 16) and the longitudinal axis of the first guide (12) for the driver (14) run parallel to one another and parallel to the longitudinal axis of the cylinder housing (1).
  • a first support (11, 7) for a first roller (8) serving as a deflecting element for the tension element (25) is arranged in the first bore section (13) of the further guide so as to be displaceable in the direction of the longitudinal axis of the second housing bore (13, 16).
  • a second support (17, 21) for a Deflection element for the tension element (25) serving second roller (22) slidably arranged in the direction of the longitudinal axis of the second housing bore (13, 16).
  • the first carrier (11, 7) and the second carrier (17, 21) also have a rectangular cross section.
  • Each support (11, 7) or (17, 21) with associated deflection element (roller 8 and roller 22) forms a deflection device (11, 7, 8) or (17, 21, 22).
  • the two supports (11, 7) and (17, 21) are designed as tubular bodies (11) and (17) and each have a fork-shaped part on their end region protruding from the associated bore section (13) or (16) (7) or (21).
  • the fork-shaped part (7) of the first carrier (11, 7) has an axis (9) running transversely to the longitudinal axis of the first carrier (11, 7), on which the first roller (8) is rotatably mounted.
  • the fork-shaped part (21) of the second carrier (17, 21) also has an axis (23) which runs transversely to the longitudinal axis of the second carrier (17, 21) and on which the second roller (22) is rotatably mounted.
  • a first spring (4) is arranged in the tubular body (11) of the first carrier (11, 7), the axial extent of which is greater than the axial extent of the tubular body (11) of the first carrier (11, 7).
  • the first spring (4) is supported at one end on the insert (15) in the further housing bore (13, 16) and acts on the other end against a wall (6) delimiting the tubular body, to which the fork-shaped part ( 7) of the first carrier (11, 7).
  • a second spring (18) is arranged in the tubular body (17) of the second carrier (17, 21), the axial extension of which is greater than the axial extension of the tubular body (17) of the second carrier (17, 21).
  • the second spring (18) is supported with one end on the insert (15) in the further housing bore (13, 16) and acts with its other end on a wall (20) delimiting the tubular body, to which the fork-shaped part ( 21) of the second carrier (17, 21).
  • the force of the first spring (4) loads the first carrier (11, 7) carrying the first roller (8) in the direction of the longitudinal axis of the cylinder housing (1) in the direction away from the cylinder housing (1).
  • the force of the second spring (18) loads the second carrier (17, 21) carrying the second roller (22) in the direction of the longitudinal axis of the cylinder housing (1) in the direction away from the cylinder housing (1).
  • the first carrier (11, 7) has a stop (5) on its outer lateral surface, which stops when the first carrier (11, 7) moves in the direction of the cylinder housing (1) can be brought into abutment on the associated end face of the cylinder housing (1), thus limiting the stroke of the first carrier (11, 7) in the direction of the cylinder housing (1).
  • the second carrier has a stop (19) on its outer lateral surface outside the further housing bore (13, 16), which stops when the second carrier (17, 21) moves in the direction of the cylinder housing (1) on the associated end face of the cylinder housing (1) can be brought into contact and thus limits the stroke of the second carrier (17, 21) in the direction of the cylinder housing (1).
  • a first cap-like cover (10) and a second cap-like cover (24) are attached, which enclose the supports provided with the rollers (8) and (22) together with the cylinder housing (1) and so protect these components from contamination.
  • the traction element (25) partially wrapping around the rollers (8) or (22) and the stops (5) or (19) on the supports (11, 7) and (17, 21) limit the stroke of the rollers (8 ) or (22) supporting beams (11, 7) or (17, 21) in the direction away from the cylinder housing (1) or in the direction of the cylinder housing (1).
  • FIG. 2 shows the cylinder housing (1) with the first housing bore (34) with piston (31), the first bore section (13) with the tubular body (11) of the first carrier (11, 7) and the driver (14) shown in section along the line AA according to Fig.1. From this figure it can be clearly seen that the first housing bore (34), the further housing bores (13, 16) serving as a further guide and the driver (14) are arranged one above the other on a common vertical axis.
  • the further housing bores (13, 16) can be designed as a single through-bore which has an insert (15) serving as a support for both springs (4) and (18) or also two inserts, each insert then having a spring (4th ) or (18) is assigned. It is of course also conceivable to omit the insert (15) so that the two further housing bores (13) and (16) together form a housing bore and thus only a single spring is to be provided, which is arranged such that its ends face away from each other the mutually facing sides of the two carriers (11, 7) and (17, 21) from the end faces of the cylinder housing (1) away.
  • two individual bores designed in the manner of a blind bore can also be provided for the supports.
  • an insert can be dispensed with, since the bottom of each blind bore would serve as spring support for the associated spring (4) or (18).
  • the bore or the bores can have a circular cross section, but also any cross section deviating from the circular shape. If a cross section is chosen that deviates from the circular shape, an additional anti-rotation lock for the supports (11, 7) and (17, 21) is unnecessary.
  • the further housing bore (13, 16) or the Further housing bores for the supports (11, 7) and (17, 21) can also be arranged in the cylinder housing (1) in a slightly oblique manner with respect to the longitudinal axis of the cylinder housing (1).
  • each carrier that carries the roller can be configured cranked.
  • Each support carrying a role can at least partially consist of a tubular body which can serve to receive the associated tension spring for supports with a role.
  • the carrier can also consist of solid material, so that the spring acts on the end face of the carrier facing the further housing bore.
  • each carrier is designed so that it is securely guided in the associated further housing bore.
  • the carrier is designed such that it is adapted to the cross-sectional shape of the further housing bore.
  • Additional stops (5) and (19) to be arranged on the carriers (11, 7) and (17, 21) can be dispensed with if the length of the carriers (11, 7) or (17, 21) is dimensioned in this way that the supports (11, 7) or (17, 21) come into contact with their end faces in the further housing bores (13, 16) on the insert (15) or on the inserts or on the bottom of the blind bores, if the carrier or carriers (11, 7) or (17, 21) have a predeterminable stroke in the direction of the cylinder housing (1).
  • Each spring (4) or (18) itself can also serve as a stop if it is in a fully compressed state (turn to turn) or if the spring is designed to be very strong.
  • the force acting on the tension element (25) pushes the first carrier (11, 7) into the further housing bore (13, 16) against the force of the spring (4), namely until the stop (5) of the first carrier (11, 7) comes to rest on the associated end face of the cylinder housing (1).
  • the force of the second spring (18) acting on the second carrier (17, 21) displaces the second carrier (17, 21) away from the associated end face of the cylinder housing (1), the stop (19) moving away from this end face of the cylinder housing (1) triggers.
  • the tension element (25) is held tensioned in the area between the driver (14), the second roller (22) and the piston (31) via the second roller (22) connected to the second carrier (17, 21).
