Definitions

  • the present invention relates to a pneumatic Actuator with the features of the preamble of the claim 1.
  • Such an actuator is from the German Utility model G9014487.2 and known from the publication US-17-4167 897.
  • the output shaft with two end shields becomes actuators stored in the housing.
  • the end shields are made by the Inside, which forms the cylinder, in the housing used, and the shaft is also from the inside with external circlips or snap rings in their Fixed axial direction.
  • the assembly of the bearings and the Circlips from the working area of the cylinder a relatively difficult manual task, which causes undesirable costs.
  • the groove can be particularly simple in the manufacture of the Well be attached if it is a wraparound recessed groove.
  • a symmetrical arrangement which allows the use of two identical pistons, results when each piston has a total of two Toothing adjacent webs. It can also be provided that the work space in the area of Bearings of the shaft in each in a groove sealing rings made of rubber or a Plastic is sealed from the outside.
  • a particularly advantageous method for assembling a so far described actuator results if first the shaft is inserted into the bearings and then the piston or pistons in engagement with the shaft brought so that the shaft without further Fasteners fixed in the axial direction and is held in particular in the storage locations.
  • Figure 1 is a pneumatic according to the invention Actuator with a housing 1, one in the housing an axis 2 rotatably mounted shaft 3 and two Pneumatic pistons 4 and 5 illustrated.
  • the housing 1 forms a cylindrical bore 6 on its inside, in which the pistons 4 and 5 to form a work space are used sealingly.
  • the longitudinal axis of hole 6 is oriented perpendicular to the plane of the drawing in FIG.
  • the pistons 4 and 5 are in the illustration according to FIG. 1 cut in the area of their engagement with the shaft 3.
  • the pistons 4 and 5 each carry one Straight toothing in the manner of a rack 20, which engages with the toothing 12 of the shaft 3 stands.
  • the axial edges of the toothing 20 are adjacent each have a web 21 which is connected to the piston 4 or 5 is integrally formed and in the grooves 11 and 13th intervenes.
  • the housing 1 itself has one in the direction the through axis 2 through hole that the Center axis of the cylinder 6 in the middle and vertically cuts.
  • This bore forms bearing points 22 which the bearings 10 and 14 of the shaft 3 together one Plain bearing for the rotation of shaft 3 about axis 2 forms.
  • the interior is in the area of the bearing points 22 of the cylinder 6 to the atmosphere with not shown sealants, for example in the form of O-rings, sealed.
  • FIG. 2 shows the actuator according to FIG. 1 in one Cross section along the axis of the cylinder 6.
  • the axis 2 of the shaft 3 is in the illustration according to FIG. 2 oriented perpendicular to the Zeirchen plane. Same Components have the same reference numbers.
  • Figure 2 illustrates how the pistons 4 and 5 die Surround shaft 3 symmetrically, the pistons 4 and 5 carry Piston bottoms cooperating sealingly with the cylinder 6 30, where the rack-like area with the Toothing 20 connects.
  • the housing 1 itself is on the End faces of the cylinder bore 6 with plate-shaped Cylinder heads 31 closed.
  • the pistons 4, 5, the Limit cylinder bore 6 and the cylinder heads 31 a total of three work rooms 32, 33 and 34, of which the work rooms 32 and 34 pneumatically parallel are switched and the workspace 33 separately Pressure can be applied.
  • Corresponding connection bores for workrooms 32, 33 and 34 are with the Reference numbers 35, 36 and 37 marked.
  • this actuator is installed by first in the housing 1, more specifically, in the Through hole with the bearings 22, the shaft 3 in Direction of axis 2 is inserted until the position 1 is reached. Then the open Ends of the cylinder bore 6 ago a piston to each Inserted side of the shaft 3 so that the teeth 20 engage synchronously with the toothing 12. At the same time, they engage parallel to the toothing 12 extending webs 21 in the grooves 11, 13. The pistons 4, 5 are then symmetrical in the hole 6 pressed in, whereby the shaft 3 about its axis 2 is rotated, the teeth 12 and 20 into each other engage and slide the webs 21 into the grooves 11, 13. By the positive engagement of the webs 21 in the Grooves 11, 13 is the shaft in the direction of axis 2 fixed without the need for additional fasteners would. The cylinder 6 is now with the cylinder heads 31st sealed and the necessary pneumatic Connections provided.
  • the grooves be as in this Embodiment shown laterally to the Adjacent teeth 12 and pistons 4 and 5 each have two webs 21.
  • the axial guidance of the shaft 3 is then. in the Operation caused only by the flanks of the pistons.
