Definitions

  • the invention relates to a method for rotationally fixed connection at least one component arranged on a shaft with the shaft, in which the component with play on the shaft threaded and in this in a certain position is held, whereupon by means of a hollow shaft moving mandrel with a larger diameter than the light Width of the wave this until reaching a desired Holding force for the component is expanded on the shaft and a device that can be used here.
  • the object of the invention was therefore a simple one Specify the process by which reaching through Widening a hollow shaft aimed at holding force Component can be monitored on the shaft.
  • the invention takes advantage of that on the shaft lined up component the expansion of the shaft by the prevents the mandrel from moving or from expanding opposed at least additional resistance. thats why to expand the shaft in the area of a lined up Component or to displace material from this area a greater force is required than to expand the shaft in areas not equipped with components. This bigger one force required to expand also moves the Dornes through the wave in this area greater resistance opposite.
  • the pushing or pulling force to move the mandrel through the hollow shaft depends on a variety of parameters ab, but it is also a function of the force to Widening the wave.
  • the invention therefore monitors the achievement of a minimum thrust or traction to move the mandrel through the hollow Wave and closes from this to the applied force Widening the wave and thus reaching the target Holding force of one pushed onto the shaft Component.
  • the invention does not attempt to calculate to achieve a desired holding force of a component on the shaft required thrust or Tensile force and determines this empirically in advance with one or several test runs on test workpieces.
  • a device claim describes the characteristics of a device, by means of which the method according to the invention are carried out can.
  • the mandrel can be pushed through the shaft but it is preferred to pull it.
  • cams 2 On a hollow shaft 1, three cams 2 are lined up and through Mounts not shown in the intended position held along the shaft and at an angle to the shaft. The In the initial state, cams 2 have joining play 3 to the shaft, that lining up allowed. The end of shaft 1 lies against it a fixed stop 4.
  • a piston-shaped mandrel 5 is attached to a pull rod 6, whose annular groove 7 at its end facing away from the mandrel via pawls 8 a driving head 9 with the piston rod 10 of a hydraulic Working element 11 can be coupled.
  • the outer diameter of the mandrel 5 is at least that Joining game 3 between the shaft 1 and the cams 2 larger than that clear width of the hollow shaft 1.
  • the mandrel 5 goes with a cone 12 from the pull rod 6 to its outer diameter.
  • the mandrel 5 has already been so far through the hollow shaft 1 pulled and has it expanding so far deformed that not only the joining game 3 between the first Cam 2 canceled, but also an interference fit between the shaft and Cam has been produced with such a high surface pressure that the cam with the necessary for its proper function Holding force is attached to the shaft.
  • the other cams 2 are also attached in this way.
  • the parameters play 3 difference between Outside diameter of mandrel 5 and clear width of the hollow shaft 1, modulus of elasticity of the material of the shaft 1 and the cams 2, and The required holding force of the cams on the shaft must, of course be coordinated.
  • mandrels or a stepped mandrel are used in succession be, whose or its diameter in the same or preferably decreasing levels to the final dimension.
  • outer contours of the individual mandrels or steps can be different his.
  • the shaft 1 By expanding the shaft 1 it becomes circular, smooth Bores of the cams 2 frictional connection achieved.
  • the cam 2 has a profile, for example in the form of a toothing have, the material displaced by the mandrel 5 Shaft 1 pressed into this profile and there is a positive connection achieved with much higher holding force.
  • the Profiling should be very coarse, e.g. wavy and the mandrel 5 can have an appropriate profile, so that Material of the shaft pressed specifically into the valleys of the profiling can be.
  • the pulling force required depends on several factors such as Wall thickness of the hollow shaft 1, stiffness of the material of the Wave, slope of the cone 12 on the mandrel 5, train speed of the Dornes et al. It is obvious that the resistance of the hollow shaft against widening and thus the pulling force on the Places will increase significantly where a cam 2 on the The shaft sits because this cam prevents the shaft from expanding.
  • the increase in traction at these points can be detected and serve as an indicator of whether the desired permanent seat of the Cam has been reached.
  • a force measuring element for example in the form of, can be on the driver head 9 a strain gauge 13 may be attached, which is the exerted Takes tensile force and forwards it to a comparison device 14.
  • a linear scale 15 on the driving head 9 articulated by one also with the comparison device 14 connected sensor 16 is scanned.
  • the required holding force a cam 2 on the hollow shaft 1 required traction and the locations along the hollow wave are determined at which this Tractive force must occur. These values can be compared to the comparison device 14 are abandoned. She then compares in the following Operations, whether the specified values are reached and emits an error signal if it is not. This can occur, for example, if the bore of a cam 2 oversize has, the wall thickness of the hollow shaft may only on the point in question is too small, a cam not at the intended place is sitting or missing, etc.
