Definitions

  • Timing belt forms are usually steel tube rolls, which are straight on their circumference toothed and used as the inner core in the manufacture of timing belts, e.g. out Perbunan gum or plastic, needed.
  • the heated toothed belt material is pressed into the toothing of the toothed belt shape.
  • the toothing of the timing belt shapes thus forms the die of the toothed belt toothing.
  • timing belt shapes It is known to produce timing belt shapes by milling from cylindrical blanks. The requirements for the accuracy of tooth geometries of timing belts is increased enormously. Thus, the tooth surface should be as smooth as possible, i. if possible have no illustrations of existing in the timing belt shapes Fräsriefen. When milling timing belt shapes, it is therefore usually necessary to the surface retread the timing belt shape.
  • the dressing means at least one profile dressing with a profiled dressing area, wherein the profile of the dressing area the Counter profile of at least part of the desired peripheral profile of at least a grinding wheel and the treading element is a dressing hard body, for example, diamond, with an edge-like dressing area.
  • the device according to the invention allows a method for the production of Timing belt forms, in which by means of at least one rotating grinding wheel with a profiled circumference in the before-processing substantially cylindrical Circumference of a workpiece is a die of the desired toothed belt toothing is incorporated, wherein the circumferential profile of the profile of a complete tooth groove of desired timing belt shape corresponds.
  • the die for the timing belt is not milled but by grinding with specially profiled grinding wheels with a grinding movement parallel to the Longitudinal axis of the workpiece generated.
  • This can be a quality of Surface of the finished workpiece can be achieved, the aftertreatment unnecessary.
  • As a tooth groove the entire area from the head of a tooth becomes the head of the adjacent tooth understood. The grinding of two adjacent tooth grooves thus results in a complete tooth of the timing belt shape being generated, i. H. Also, the outer diameter of the timing belt shape is ground.
  • the toothed groove of the timing belt shape must be the shrinkage of the toothed belt material during cooling in the manufacturing process.
  • profiled grinding wheels also allows the finest in a simple way
  • z. B. a wavy sub-profile in Range of tooth flanks.
  • for. B. parallel to the toothed belt forming axis running channels are introduced into the profile.
  • Timing belt with such Subprofiles are disclosed in DE 199 08 672 C1.
  • the dressing is required due to the gradual wear of the grinding wheel.
  • the use of a profile dressing element with profiled dressing area has the advantage that a complex CNC control for the movement of other dressing means, such as Example of a dressing pin, not required because the profiled dressing area a fixed profile pretends.
  • a profile dressing element is therefore particularly useful if variations of the profile shape are not needed and high volumes with identical Vernierungsgeometrien are to produce.
  • the device according to the invention can also be designed so that the positioned at least one profile dressing relative to the workpiece holder and is adjustable that in the direction of the longitudinal center axis of the at least one clamped Tool looks at the projection of the profile of the dressing area a tool face the profile of the cross section of a grinding process aspired cut corresponds.
  • the rotating grinding wheel it is possible for the rotating grinding wheel to be single straight-line translational movement first to lead along the profile hard body and to achieve the desired Abraum of the peripheral profile of the grinding wheel and then perform the grinding process on the workpiece.
  • a Adjustment of the grinding wheel towards the longitudinal central axis of the workpiece radial direction is therefore no longer required for the grinding process.
  • the relative movement between grinding wheel and workpiece can be achieved by a movement the grinding wheel with respect to a machine frame or a movement of a Tool holder can be achieved.
  • Fig. 1 shows a grinding device with a machine frame 1, on which a horizontal movable grinding table 2 is attached.
  • the grinding table 2 carries a workpiece holder 3, in which the roller-shaped blank 4 for a toothed belt form between a Dividing unit 16 and an abutment 17 is clamped.
  • a rotary driver 5 the blank 4 can be controlled by means of a turntable 6 about a horizontal axis of rotation 7 to be turned around.
  • the axis of rotation 7 forms in the blank 4 at the same time the longitudinal central axis of the blank 4.
  • the workpiece holder 3 does not include a separate here presented high-precision direct measuring system, the exact rotational angle adjustment allowed.
  • Above the workpiece holder 3 is on a grinding wheel holder.
  • the grinding wheel holder 8 a grinding wheel 9 rotatably fixed.
  • the grinding wheel holder 8 is highly precise in vertical direction controlled movable.
  • To form a toothed belt shape from the blank 4 To obtain in the scope of the blank 4, the counter profile of Toothed belt teeth are incorporated, the toothing in the direction of Longitudinal axis of the blank 4 is rectilinear and constant.
  • the scope now forms viewed in cross-section, the die for the toothed belt toothing.
  • the grinding wheel 9 has on its circumference a profile 10, which in an enlarged Representation in Fig. 2 is visible.
  • the circumferential profile 10 of the grinding wheel 9 corresponds the desired profile of a Zahnnut the timing belt shape.
  • Timing belt shape is the blank 4 by means of the grinding table 2 at lowered Grinding wheel 9 so moved that the grinding wheel 9 over the entire length of the Blanks 4 in the blank 4, the die for a complete tooth of Timing belt cuts in. After that, the blank 4 is at a predetermined angle ⁇ turned and the next tooth matrix generated. At every grinding process will also the outside diameter of the blank 4 mitgeschliffen, so that in a finished Timing belt shape the entire surface is ground.
  • the circumferential profile 10 can the grinding wheel 9 with a dressing pin 11 before each grinding re-dressed become. This is done with the help of a CNC-controlled process.
  • the dressing pin 11 is for one with respect to the axis of rotation of the grinding wheel axialer as well as in radial Direction movable.
  • the dressing pin 11 still has a dressing pivot axis 12 substantially perpendicular to the axial and radial directions and through the Center of a round diamond 13 at the top of Abrichtstartes 11 runs. With equipped with such degrees of freedom, can with the dressing pen 11 almost every Any profile can be entered in the circumference of the grinding wheel 9. Especially it is possible to incorporate fine substructures in the circumferential profile 10.
  • the grinding wheel is constantly using a spray nozzle pair 14 (Fig.1) cleaned, the two flanks of the peripheral profile 10 sufficient reached evenly.
  • the Nozzle pair 15 is arranged in the immediate vicinity of the grinding papers 9.
  • Fig. 4 shows an alternative construction of a grinding device. Corresponding one another Parts in different figures are provided with the same reference numbers. Of the Blank 4a is shorter in Fig. 4 than in Fig. 1. The tool holder 3 has in its dividers 16 and 17 the same distance as in Fig. 1.
