Definitions

  • the invention relates to a rotary-lifting device which is sufficient to implement a wide range of kinematic movements.
  • such devices are known as so-called energy converters for alternating swivel-thrust movements, with the linear drive unit being coupled to a swivel motor that works on the screw or cam drive principle, the swivel movement of which is in the range from 90 ° to 720 °.
  • Swivel-stroke combinations of this type limit the rotary movement of the piston rod and in this way limit the area of application.
  • This limitation is due to the principle of operation of the rotor, so that the application always fails when the rotating movement is required.
  • the object of the invention is to eliminate the disadvantages of the prior art and to develop a rotary / lifting device which controls units can, which must control any spatial point within the path coordinates of the system in the working and operating process, the device being easy to manufacture in terms of production technology. It should have a reduced size and a low control and regulation effort, the wear and failure susceptibility should go to zero.
  • the device ensures the control of any desired spatial point within the path coordinates of the coupled units, the spatial point depending on the volume flows of the linear motor and rotating rotor can be controlled as often as desired and is therefore independent of the angle of rotation.
  • the manufacture of the device is technically simple with a reduced size.
  • the control of the arbitrary room points is effected by means of a small expenditure on control and regulation technology, the wear and the susceptibility to malfunction being very low. Every position in the room is reached even under load.
  • the device ensures that the drive shaft of the rotor, which is in operative connection with the device, rotates axially without load.
  • the double-acting hydraulic linear motor 1 consists of an outer cylinder 4, to which an inlet line 5 and an outlet line 6, a left-hand bore 7 and a right-hand bore 8 are assigned, with a pressure medium 9 in a left-hand cylinder space - 10 and located in a -right cylinder chamber 11.
  • a piston rod guide 12 is provided with piston rod guide rings 13, with seals 14 and with a scraper 15 in order to ensure a safe mounting and sealing of a piston rod 16.
  • the piston rod guide 12 is connected to the outer cylinder 4 via the thread 17 and is centered in position via a snug fit 18.
  • the seal 19 inserted into the fit 18 guarantees the seal in the inner outer cylinder 4.
  • Piston guide rings 21 are provided for transmitting the large radial loads to a piston 20.
  • the piston 20 carries a piston seal 22, which prevents the pressure medium 9 from flowing over the inside diameter of the outer cylinder 4 into the respective pressure-free cylinder chamber 10 or cylinder chamber 11.
  • the piston 20 is connected to the piston rod 16 via the feather keys 23 and at the same time via the coupling element 3 to the drive shaft 24 of the endlessly rotating rotor 2.
  • the drive shaft 24 is provided with drive keys 25 which are fastened on the drive shaft 24 with vertical screws 26.
  • the drive keys 25 for the drive shaft 24 are arranged offset from the keys 23 by 45 °. In order to keep the piston 20 in a stable position on the piston rod 16 - in the event of the action of axial forces on the piston 20 - shaft locking rings 27 are provided.
  • the positive connection of the piston 20 enables shock-free storage, since the pressure medium 9 penetrates into the gaps between the deviations in fit and in this way enables a smooth transmission of force.
  • a sealing bush 28 is required, in which the seal 29 is located.
  • the sealing bush 28 is connected to the screw 30 with the Piston 20 connected and transmits, in connection with the shaft locking ring 27, the axial forces generated when pressurized.
  • the coupling element 3 slides over the drive keys 25 and transmits the torque generated by the endlessly rotating rotor 2 to the keys 23, so that the piston rod 16 is set in rotation.
  • the endlessly rotating rotor 2 consists of a right outer housing 32 and a left outer housing 33; both are connected to each other by the screw elements 34.
  • a supply line 35 and a discharge line 36 are arranged in the right outer housing 32.
  • a fluid 43 which is supplied or discharged is guided via upper bores 44 and lower bores 45 into a piston chamber 46, where the pressure energy is converted into a rotating movement.
  • the central bore 47 provided in the drive shaft 24 serves for the pressure-free return of the fluid 43, which reaches a cavity 48 of the piston rod 16 when the piston rod 16 is extended.
  • An output pin 49 of the piston rod 16 can have different embodiments for the connection of the implement. (Square; parallel key; serration; spline ect).
  • the sealing rings 50 ensure the sealing of the piston chamber 46 via the end face of the cam carrier 37.
  • Another binding element 51 is integrated in the left outer housing 33 and the right outer housing 32.
  • the double-acting hydraulic linear motor 1 and the endlessly rotating rotor 2 are sealed off from one another by the outer sealing ring 52.
  • the function of the rotary-lifting device is characterized in that the drive shaft 24 of an endlessly rotating rotor 2 is positively connected to the piston 20 of a double-acting hydraulic linear motor 1 via the coupling element 13, which makes it possible for the linear Movement of the piston 20 to overlay a rotating movement.
  • the piston 20 is connected in half its length via a positive connection by means of a key 32 to the piston rod 16 and the other half of the piston is also positively connected by means of drive keys 25 and coupling elements 13 to the drive shaft 24 of the endlessly rotating rotor 2.
  • the drive shaft 24 enables coupling over the length of the stroke of this positive connection, whereby the transmission of the torque along the stroke of the linear unit is ensured.
  • the piston 20 is connected to the piston rod 16 via the form-fitting coupling element 3, the piston 20 can deflect radially within the scope of its fit values, as a result of which a floating bearing is achieved.
  • the pressure medium 9 is stored between the sliding surfaces of the positive connection and forms an elastic buffer which acts to the advantage of sealing and power transmission.
  • shaft locking rings 27 are provided which prevent the piston 20 from being pushed off the piston rod 16.
  • the endlessly rotating rotor 2 is connected via the binding element 51 to the outer cylinder 4 of the double-acting hydraulic linear motor 1 in a seal-proof manner by means of an outer sealing ring 52.
  • piston guide rings 21 are provided which are arranged in the piston 20.
  • a thrust washer 53 ensures that the piston rod 16 remains rotatable under load even in the end position.
  • seal packages 14; 15; 22 installed, which prevent the unwanted outflow, in the form of external and internal leakages, and the ingress of dirt.
  • the rotary / lifting device can be fastened with a flange 54 provided on the outer cylinder 4 of the double-acting hydraulic linear motor 1.
  • a flange 54 provided on the outer cylinder 4 of the double-acting hydraulic linear motor 1.
  • other designs are also possible (foot mounting, flange on the rotor).
