Definitions

  • the invention relates to an assembly of an engine-driven shaft and a boss connectable with it, of a part mountable on said shaft, in which, for establishing said connection, said shaft and said boss are provided with mutually adapted screw threads arranged on an outer and inner conical part, respectively, said screw thread having a trapezoidal cross-section.
  • the end position of engaging parts is determined in that the boss almost abuts a shoulder on the shaft.
  • the remaining small tolerance is eliminated by exerting a moment on the drilling rod, as a result of which the screw thread will be slightly deformed, so that the boss will come to lie against the shoulder of said shaft.
  • said known assembly is particularly suited for accomodating impact forces exerted on the shaft in its longitudinal direction.
  • the shaft will be subject to tensile forces and pressure forces so that certain threads of both screw threads will be loaded more strongly than other threads. This will adversely affect the strength of the connection.
  • impact forces will occur to a lesser degree than radial and tangential loads.
  • both screw threads of both parts and the parts themselves are designed such, that screwing said parts together can take place until one flank and top of one screw thread tightly abut a flank and a valley of the screw thread of said other part, in which both screw threads, having a cross-section substantially in the shape of an isosceles trapezium, have been designed such, that there is tolerance between the other flanks.
  • the cutter When applying the invention, on mounting the cutter, it can be slid across part of the conical end of the shaft so that it is centered in relation to said shaft, before it should be rotated. Thus, in sliding on the shaft, the cutter will almost automatically end up in the correct position in relation to the shaft.
  • the number of rotations to be performed by the cutter during mounting can be much smaller than in case of cylindrical screw thread.
  • the loosening moment is smaller than the moment that can be produced by the engine with a directio of rotation opposite to the normal direction of rotation. Then, the boss can be held and the engine can be rotated in said direction of rotation.
  • DE-659.079 can be referred to, from which it is known per se to provide conical parts of a shaft and a boss with screw thread, in which the shaft is not provided with a shoulder to be abutted by said boss.
  • a screw thread having a sawtooth cross-section is used, its planes square to the longitudinal axis serving for absorbing the impact forces exerted on the shaft. It will be clear, that the sharp angles of the teeth are susceptible to damage. This would be a disadvantage with employment with a cutter and cutter shaft particularly when the cutter is to be replaced under operating conditions.
  • EP-0273016 shows a connection between two pipes almost corresponding to the one disclosed in EP-0703396.
  • US Patents 4508375, 5498035, 4828295, 5360239 and DE Patent DE-207183 also relate to sealingly connecting pipes.
  • the sealing between the parts plays no role whatsoever, but the only aim is to obtain a best possible connection between said parts, as a consequence of which a large torque can be transferred.
  • Fig. 1 shows a cross-section across a part of the shaft and the boss before it is screwed onto said shaft.
  • the shaft is indicated by 1 and the threaded 2 conical part by 3.
  • the cutter 4 is provided with a boss 5 having a conical bore 6, in which screw thread 7 has been provided.
  • the screw thread 7 of the boss 5 will have to be adapted to the screw thread 2 of the shaft 1. This should be taken into account when replacing a cutter 4.
  • the invention relates both to the design of the shaft 1 and of the boss 5, which can be separate parts.
  • Fig. 2 shows the end of the cutter shaft 3 on which the screw thread 2 is provided. Seen in an axial plane, the apex ⁇ of the conical part 3 and of the outer plane 8 of the screw thread will be between 10° and 50°.
  • the cross-section of the screw thread is trapezoidal and the angle ⁇ enclosed by the flanks 9 and 10 of the scrw thread, seen in an axial plane, will be between 10° and 50°.
  • the top 13 of the screw thread 2 does not abut the valley 14 of the screw thread 7, but the top of the screw thread 7 abuts the valley of the screw thread 2.
