Definitions

  • the present invention relates to the conjugate forms called "tooth entries" given to the teeth of fixed gears and sliding gears to facilitate their meshing.
  • the lateral faces of the teeth advantageously have suitable shapes so as to create, under the effect of the axial force of the sliding pinion, a tangential result which produces the necessary rotation.
  • These appropriate shapes of the side faces of the teeth are called “tooth inlets.”
  • teeth entries of various types and various types have been made. They can be classified into different genres:
  • Dhedrons the edge of which may be in the plane of the lateral face of the pinion or inclined relative to this plane.
  • Cylindrical or approximately conical shape whose generatrices are radial with respect to the pinion. Double domed, barrel-shaped.
  • the limits of the possibilities of these teeth inlets are easily determined by examining a schematic projection of the teeth inlets on a plane perpendicular to the axes of the pinions, as shown in FIG. 1: The examination of this projection shows in Indeed, as long as two median generators 10 and 10 'of the teeth inlets of one pinion cross two median generators 11 and 11' of the other pinion, there cannot be a gear.
  • the present invention relates to a new form of tooth entries, such that the possibility of gear is as perfect as possible, while obtaining, at the time of the gear, a contact between two generators and not only between two points. .
  • these teeth entries are defined by the following geometric construction: They have a conical shape, the axis of the cone not being radial with respect to the pinion (or even inclined with respect to the radial plane), but parallel to the axis of the pinion, the axes of the cones of said tooth inlets are found inside the pitch circle of each pinion, the distance between the axes of the cones of two adjacent teeth is identical for the two pinions, the angle at the top of the cones is the same for the two pinions, in addition, the radius of the circumference of the small face of the truncated cone is less than the offset of the axis of the cone relative to the original circle.
  • the contact, with the gear, is made according to a generator and not on a point of each tooth.
  • FIG. 1 schematically represents the projection of the median generatrices of the inputs of teeth previously known on a plane perpendicular to the axes of the pinions.
  • Figures 2a, 2b, 2c respectively show a perspective view, a front view and a side view of a tooth inlet according to the invention.
  • FIG. 3 shows, in radial section, the approach of two pinions provided with such teeth inlets, before the gear.
  • the tool determines, by a rotation of 180 °, a half-truncated cone towards the top of the tooth. The tool is then released towards the base of the tooth and thus connects the profile of the base of the tooth with the body of the pinion.
  • This execution can be carried out on machines of different types, either, for example, a milling machine to reproduce, or a specially designed machine, so that the conical cutter rotates around each tooth by 180 °.
