Definitions

  • the present invention relates to a rotating device for load-handling equipment, in particular felling gripper for timber harvesting, with a rotating unit of stator, rotor and rotary drive, a rotary feedthrough with a co-rotating with the rotor first part and a fixed second part and sealed channel connections between the two parts for the passage of fluid such as pressure oil and / or electrical lines for supplying work equipment such as grippers, saws and shears, and optionally a braking or blocking device for temporarily locking the rotor relative to the stator.
  • fluid such as pressure oil and / or electrical lines
  • work equipment such as grippers, saws and shears
  • a braking or blocking device for temporarily locking the rotor relative to the stator.
  • Such a rotating device is known, for example, from EP 0 809 735 B1.
  • this rotating device of the co-rotating with the rotor part of the rotary feedthrough is formed in a separate component, while the fixed part of the rotary feedthrough is provided in the stator.
  • the stator in this known rotating device fluid channels, which open into a central recess in the stator, in which engages the co-rotating part of the rotary feedthrough.
  • the fluid channels formed in the stator are in fluid communication with the channels of the part of the rotary union which rotates with the rotor, irrespective of its rotational position.
  • the invention has for its object to provide a rotating device of the type mentioned, which is more flexible.
  • the rotary device should be easy to adapt to different needs in terms of type and number of rotary unions.
  • the rotary feedthrough including the fixed part is formed in a separate from the stator and rotor component, which is inserted into a central recess in the rotary unit.
  • the rotary feedthrough can basically be varied as desired, without the rotary unit or other components of the rotating device must be changed.
  • rotating devices with only two hydraulic passages passed through can be combined with the same rotating unit as rotating devices with four, six or more guided channels.
  • a passage of electrical lines, in particular power supply lines for implements to provide as an alternative.
  • Basic elements, namely in particular rotary units can be prefabricated and then combined with appropriate rotary feedthroughs according to customer requirements if required.
  • a part of the rotary feedthrough is designed as a cylinder and the other part as a patch on the cylinder sleeve.
  • This is constructively advantageous and allows in a relatively simple manner the provision of a different number of guided channels. For this it is only necessary to increase or decrease the length of the cylinder and the sleeve accordingly.
  • the rotating second part of the rotary feedthrough is designed as a cylinder and the fixed first part as a sleeve. This has proved to be structurally advantageous.
  • the ports for the supply and discharge of the hydraulic can be arranged distributed to and from the rotary feedthrough over the entire circumference of the fixed second part. The distribution can be adapted to the particular needs of the associated machine.
  • the co-rotating first part of the rotary feedthrough is in particular rotatably connected in particular with the rotor, while the fixed second part must be fixed to the stator only against rotation.
  • the fixed second part of the rotary feedthrough can only be fixed axially relative to the first part and, moreover, can be mounted in a floating manner. During operation voltages can be reduced.
  • the braking device is formed in a further separate component.
  • the braking device can optionally be provided or not provided.
  • the braking device comprises, in particular, a first part, which is connected in a rotationally fixed manner to the stator, and a second part, which is non-rotatably connected to the rotor. This also results in a relatively simple structure.
  • the first part and the second part of the braking device each have lamellae which are mutually engageable to prevent rotation of the two parts.
  • Such multi-disc brakes have proven to be safe and effective in operation.
  • the first part and the second part of the braking device each have a sprocket or partial sprocket, which are mutually engageable to prevent rotation of the two parts. Even such a positive fixing of the two parts against each other has been found to be advantageous in operation. Here particularly large forces can be absorbed.
  • the braking device is mounted radially on the outside of the rotary unit.
  • the first part of the rotating device comprises a ring, which is shrunk onto the stator.
  • the rotary drive of the rotary device according to the invention is preferably designed as a hydraulically operated radial piston drive. This results in connection with the features of the invention space advantages.
  • the supply and removal of the hydraulic oil for the drive can also be done via the rotary feedthrough, in particular via its rotating part. This is particularly advantageous in connection with a flat distributor.
  • Fig. 1 shows a section through a rotating device according to the invention.
  • the rotary device shown in FIG. 1 comprises a rotary unit 1 with a stator 2, a rotor 3 and a rotary drive 4.
  • the rotary drive 4 is designed as a known hydraulic radial piston drive having a plurality of piston elements arranged radially in the stator 2 with respect to the rotational axis I.
  • Cylinder arrangements 5 The cylinders 6 of the piston-cylinder arrangements 5 are each formed by a circular cylindrical cross-section recess 6 in the stator 2, in which a piston 7 is displaceably guided in the radial direction.
  • a piston pressure chamber 9 is formed in each case.
  • a compression spring 10 is arranged in each case, which is supported on the one hand at the bottom 8 of the recess 6 and on the other hand on the piston 7.
  • a roller-shaped rolling body 11 is provided in each case, which is rotatably mounted on the piston 7 about an axis II parallel to the axis II.
  • a cam track 12 which is provided on the rotor 3 opposite the piston 7.
  • the distance of the cam track 12 from the rotation axis I changes cyclically around the rotation axis I between a maximum distance in which the piston 7 is extended, and a minimum distance in which the piston 7 is retracted.
  • Stator 2 and rotor 3 each have a stepped, central passage opening 15, 16.
  • a cylinder 17 is inserted from the rotor side and from the stator side a sleeve 18 which surrounds the cylinder 17 on the outside.
  • the cylinder 17 forms the first part of a rotary feedthrough, and the sleeve 18 forms a second part.
  • the first part 17 of the rotary feedthrough has a on the rotor side on this projecting portion 19 which is widened in circumference relative to the located within the passage openings 15, 16 located portion 20 in the periphery.
  • the first part 17 of the rotary feedthrough force and positively fixed to the rotor 3.
  • the first part 17 of the rotary feedthrough further has axial channels 23, which open partly on the one hand in the stator 2 facing away from the end face 24 of the enlarged portion 19 and the other part via radial channels 25 in the outer periphery 26.
  • the sleeve 18 is formed with its inner circumference fit exactly to the outer circumference of the cylinder portion 29. Opposite to the radial channels 27, the sleeve 18 is provided on its inner side 30 with annular grooves 31. These are connected via radial channels 32 with hydraulic connections 33 in connection.
  • the sleeve 18 has two hydraulic ports 34 which are each connected via a radial passage 35, each with an axial passage 36.
  • the axial channels 36 open in the stator 2 facing end face 37 of the sleeve 18.
  • These mouths 38 opposite axial channels 39 are arranged in the stator, which are connected to radial channels 40 which open on the inner peripheral side 41 of the stator 2 in annular grooves 42.
  • Radial channels 43 which are connected via axial channels 44 with further radial channels 45, which in turn are opposite annular grooves 46 in the inner peripheral side 14a of the distributor 14, are arranged in radial direction in the section 20 of the cylinder 17.
  • These annular grooves 46 communicate with channels 47 of the distributor 14 and permit the supply and removal of hydraulic oil through the distributor 14 in the piston chambers 10 of the piston-cylinder units fifth
  • the sleeve 18 is inserted into a shoulder 48 in the stator 2. Via a plate 49 and screws 50 which are arranged on the stator-side end face 24 'of the cylinder 17, the sleeve 18 is fixed axially.
  • the hydraulic channel 36 can then also be provided in the cylinder 17 so that the hydraulic oil is not first passed over the stator (2).
  • the rotor 3 is rotatably mounted relative to the stator 2 via cross rollers 51.
  • bearings 52 between the stator 2 and rotor 3 and between the cylinder 17 and sleeve 18 of the rotary feedthrough are provided. All hydraulic channels are sealed against each other by means of seals 53.
  • a brake ring 55 is shrunk.
  • a retaining ring 56 which surrounds the rotor 3.
  • slats 57 are arranged rotationally fixed, which are arranged in alternation with fins 58.
  • the fins 58 are in turn rotatably connected via a ring 59 and screws 60 with the rotor 3.
  • An annular piston 62 which compresses the lamellae 57 and 58 and thereby prevents the lamellae 57, 58 from rotating relative to one another, is loaded over the disk springs 61 which are supported in the ring 55.
  • the piston 62 can be acted upon by drive pressure oil via a channel (not illustrated here) against the pressure direction of the plate springs 61.
  • the plate springs 61 are compressed and the slats 57, 58 detached from each other. That is, with pending drive pressure, the multi-disc brake is released and the drive pressure oil can rotate the rotor 3 relative to the stator 2.
  • the illustrated rotary device thus comprises a rotary feedthrough 17, 18 which is formed in a separate from the stator 2 and rotor 3 component, which is inserted into a central recess 15, 16 in the rotary unit 1.
  • the rotary feedthrough 17, 18 can be replaced without problems against another rotary feedthrough, for example, has fewer channels guided through or at the terminals 34 are arranged differently. Also, in addition or alternatively, an electrical feedthrough be provided in the rotary feedthrough. The remaining components of the rotating device according to the invention remain unchanged.
  • the brake device 55 to 62 can also be omitted.
  • the rotating device can thus be used with or without braking device, without the other components have to be changed for this purpose.
  • the rotary unit 1 can be used completely alone, that is, without rotary feedthrough 17, 18 and without braking device 55 to 62.
