Definitions

  • the invention relates to a rotary power head to the head Driving a drill pipe of a drill with one from a hydraulic motor via a clutch driven reduction gear, the housing of the Hydromotor to one arranged in the area of the clutch Housing bell and the housing bell to the housing of the Reduction gear is flanged.
  • the invention is therefore based on the object Power turret of the type mentioned so far develop that he is significantly lower in operation Noises developed so far.
  • the solution to this problem according to the invention consists in that the coupling as an elastic coupling with elastic Torque transmission elements is formed and the Bell housing made of two elastically connected Bell rings is built.
  • the invention is based on the knowledge that the elastic connection of the rotating parts of the hydraulic motor / reduction gear by no means sufficient to make a remarkable Reduction of noise emissions during operation too to reach. Surprisingly, however, this works if in Combination with the housing of the hydraulic motor and that Reduction gear housing from its rigid connection solved and via an elastic connection of the divided bell housing can be connected to each other. In practice it has been shown that such Power turret surprisingly runs significantly quieter and can therefore be used anywhere without any problems.
  • Embodiment made the arrangement so that the elastic coupling is a claw coupling, between the Steal the elastic torque transmission elements are arranged.
  • These elastic torque transmission elements are preferably made of polyurethane with a Hardness between 89 and 95 Shore-A, especially 92 Shore-A.
  • the training is in detail preferably such that the two bell rings at their mutually facing ends with each other parallel connecting flanges are provided under Intermediate layer of an elastic damping ring elastic are interconnected.
  • the connecting flanges can be easily directed inwards so that none Enlarged diameter of the bell housing results.
  • the elastic damping ring and the elastic Damping ring elements made of acrylonitrile butadiene rubber with a hardness between 79 and 85 Shore-A, in particular 82 Shore-A.
  • the power turret shown in the figures is used for driving a drill pipe of a drilling device at the head end. This requires a detailed one Description not, because the structure and functionality in the Experts are well known.
  • the power turret points a only partially shown hydraulic motor 1, the drives a reduction gear 3 via a clutch 2.
  • the housing 4 of the hydraulic motor 1 is on a bell housing 5, which is arranged in the area of the coupling 2, flanged, while the bell 5 in turn on the Housing 6 of the reduction gear 3 is flanged.
  • FIGS. 1 and 3 From a comparative view of FIGS. 1 and 3 recognizes one that the clutch 2 as an elastic claw coupling with elastic torque transmission elements 7 is trained.
  • the two parts of the clutch 2 with claws 8 extending in the axial direction provided, which alternately interlock. Between neighboring claws are the elastic torque transmission elements 7 arranged, which has an inner ring 9th are interconnected.
  • the inner ring 9 with the Torque transmission elements 7 consists of polyurethane with a hardness of 92 Shore-A.
  • FIGS. 1 and 2 the bell housing two bell rings 10, 11 elastically connected to one another is constructed.
  • the two bell rings 10, 11 are on theirs mutually facing ends with perpendicular to the longitudinal axis, connecting flanges 12 parallel to one another, which are directed inwards and with the interposition of a elastic damping ring 13 elastically connected to each other are.
  • the two connecting flanges 12 by evenly distributed over the circumference arranged screws 14 connected together. This Screws 14 are through recesses 15 in the one connecting flange 12 and the damping ring 13 in threaded holes 16 of the other connecting flange 12 screwed.
