Definitions

  • a well-known well-known component is that the locking elements and the driving elements are made in the form of splined and free spacers, as a result of the fact that there is a short circuit in them.
  • a well-known well-known feature of the condi- tion is that the cylindrical roller comes into the depths of shallow depth, and this increases the wear part of the vehicle.
  • the proposed downloadable pneumatic shock absorber is operated on by the way that the transmission elements of the rotating momentum are executed in the form of discharges. With this, the length of the segments is shorter than the total length of the opening and the final section, performed in part of the larger longer period and the larger is the longer maximum

  • Part 13 of the larger diameter of the adapter is connected to a stage 8 of the larger diameter of the unit and has an external 14 and an external interior of 15 mm.
  • Adequate phases 9 are associated with a part of 14 in part 13 of the larger diameter of the adapter.

  • the adapter of the pneumatic device is inserted into the unit 1, and, in addition to this, the holder of the drill case 3 is placed in the central unit of 10 units.
  • the lock elements 1 1 combine with the adjacent sections 5, and the drill compartment is entered into the adapter for the unit. With this, the lock elements 1 1 are interchanged with interchangeable phases 7. They produce a drill hole in front of her axle. With this, the locking elements 1 1 can be combined with an integral part 6 (the length of the integral part 6 is less than the length of the part 5), and the elements of the transmission part 12 can be used for The owner of the drill is entering the unit in front of the unit.
  • Torque transmitting elements 12 are included in the optional advanced stages 9 and they prevent the transmission of the momentum of the drive from the pneumatic drive.

Abstract

Cette invention se rapporte au domaine des outils à percussion et concerne notamment des structures d'outils et de colonnes de forage. Ce marteau pneumatique immergé comprend un corps dans lequel se trouve un piston-percuteur, ainsi qu'un trépan comportant une tige étagée. La surface externe de l'étage de moindre diamètre comporte des gorges longitudinales et transversales destinées à des éléments de verrouillage, tandis que la surface externe de l'étage de grand diamètre comporte des gorges longitudinales complémentaires et un raccord en deux parties comportant une ouverture centrale. Les éléments de verrouillage et les éléments de transmission de moment rotatif peuvent, par exemple, se présenter sous forme de rouleaux. La partie du raccord possédant le plus grand diamètre est reliée à l'étage de grand diamètre et possède, sur sa surface interne, des gorges non traversantes dans lesquelles viennent se loger les rouleaux cylindriques. Ce dispositif permet de réduire l'usure et de prévenir la rupture du raccord et du trépan, ceci grâce à un allégement des charges mécaniques qui s'exercent lors du fonctionnement du marteau pneumatique immergé.
