Definitions

  • the invention is directed to a hydraulically or pneumatically pressurizable Rotary actuator used in industry for swiveling Valve flaps, devices etc. is used, being on the piston rod a torque and a swivel angle is required.
  • the main components of such rotary drives are the piston rod, the Piston and the cylinder barrel. There are cylinder spaces on both sides of the piston, which are sealed against each other and to the outside. At reciprocal loading of the cylinder rooms with pressure medium the piston is moved in the longitudinal axis of the cylinder.
  • the piston has on its outside diameter and on its inside diameter counter-rotating steep threads, the inside with the piston rod and outside with an intermediate ring with the cylinder barrel are connected.
  • the invention has for its object to provide a rotary drive which can also be used for mechanical resetting when installing a spring assembly the size of the piston determined by the desired torque maintains.
  • the rotary drive is designated 1. This is connected to the valve flap 3 by screws 2.
  • the stem 4 of the valve flap is positively connected to the piston rod of the rotary drive by, for example, parallel keys.
  • the rotary movement of the piston rod is thus transmitted to the valve flap and brings it into an open or closed position.
  • the pressure medium is fed to the rotary drive alternately via connections 5 and 6 from a pressure generating system, not shown.
  • connection 5 and 6 are shown in section of the housing 12. Pressure medium is supplied to the piston chamber 7 of the piston 8 via the connection 5.
  • the piston chamber 9 is connected to the tank via a control, not shown.
  • the piston spaces 7 and 9 are against each other by the seals 22 and 23, and sealed to the outside by the seals 24, 25, 26 and 27.
  • the piston 8 moves in the direction of the housing cover 10 Change the pressure medium supply to port 6 and that Connecting the port 5 to the tank through the controller will Reverse piston movement.
  • the piston rod 16 is axially fixed by split insert rings 17 and 18 with the interposition of roller bearings 19 and 19a and performs a pure rotary movement when the piston 8 is axially displaced, whereby a certain torque is generated in accordance with the hydraulic pressure of the pressure medium.
  • This torque can be transmitted to the drive shaft of a wide variety of units using, for example, parallel keys.
  • the piston rod 16 is passed through the housing base 10 and is at its outer end e.g. provided with a square 16a.
  • the piston rod 16 By turning the square by hand using a lever the piston rod 16 can be rotated in an emergency. Also serves the square through a marking to indicate the position of the piston rod.
  • Fig . 3 shows a rotary drive with spring return of the piston.
  • Fig . 4 shows a rotary actuator with spring return according to the proposal of the invention.
  • the tube 20 is connected on the side facing away from the piston 8 to the auxiliary piston 28, which is provided with seals 29 and 30, via a thread.
  • the tube sleeve 35 is fixed by the locking ring 36 and takes over the leadership of the spring assembly 37.
  • the additional piston 38 is supported on the spring assembly 37, which has contact 39 with the auxiliary piston 28 via its extension 39 and the intermediate roller bearing 40.
  • the additional piston 38 is provided with the seal 41 and is longitudinally displaceable in the spring cylinder tube 31 against the force of the spring assembly 37. The displacement path is limited by the shoulder 42 in the spring cylinder tube 31.
  • the spring cylinder tube 31 is over the housing cover 32 with the seals 33 and 34 sealed to the outside.
  • the spring cylinder tube 31 is with the housing cover 32 via the thread 44 releasably connected.
