Definitions

  • the invention relates to a device for mounting a winding roller intended to facilitate the winding of the belts on an alternator pulley.
  • alternator At least one roller which presses the belt in the region of its passage on the pulley.
  • this roller roller is fixed to the cylinder block or to the cylinder head by a steel spacer; the spacer consists of a cylindrical sleeve carrying an end shoulder over which the hub of the roller is passed, provided with its rolling bearings, and which is fixed to the spacer by the head of a screw whose the threaded part passes through the hollow sleeve and is screwed into a threaded hole formed in the casing.
  • a problem related to this solution is the difficulty of finding an adequate location in the environment of the alternator for fixing the take-up roller, where it follows that the belt winding is not always optimized.
  • mounting the take-up roller represents an additional mounting operation which increases the time and overall cost of mounting the engine.
  • the object of the invention is to find a new solution for placing and fixing the alternator winding roller which eliminates the drawbacks mentioned.
  • the invention achieves its object by means of a winder roller spacer for an alternator fixed to an engine part by means of at least one fixing screw, the spacer consisting of a cylindrical axis carrying a terminal shoulder on which we come pass the hub of the take-up roller, fitted with its bearings. bearing, and that is just fixed to the spacer by a clamping means linked to the axis, the spacer being provided with means for fixing to a support linked to the motor, characterized in that said means for fixing to the support comprise a screw integral and coaxial with said axis supporting the winding roller, the screw being adapted to constitute the alternator fixing screw.
  • the alternator fixing screw crosses and clamps two fixing lugs provided on the alternator, as seen for example in document US 4835428 or US 4,849,665, and it is therefore at this location that is provided the screw spacer according to the invention, carrying the roller reel.
  • the cylindrical axis comprises a form of tightening of the spacer screw, for example hexagonal sections.
  • the cylindrical support axis of the take-up roller is hollow at its end and allows the screwing of a second screw then forming the means for tightening the hub of the take-up roller.
  • Other clamping means can be provided, such as keys.
  • FIG. 1 is a schematic sectional view of the device for fixing the winding roller on the spacer screw for fixing an alternator
  • FIG. 2 is a perspective view of said spacer screw.
  • Figure 1 schematically illustrates the lower part of an alternator
  • the screw 4 comprises a threaded tail 5, a guard flange 6, a cylindrical spacer or axis part 7, a flange 8 for the roller stop, a cylindrical bearing surface 15 and a hexagonal screw head 9.
  • the screw 4 is hollowed out, on the head side, by a tapped recess 10. This can accommodate the threaded shank 11 of a roller fixing screw 12, comprising a hexagonal head 13 and a guard flange 14.
  • the roller roller 20 comprises a hub disc 21 (with integrated bearings not shown) with central orifice 22 corresponding substantially to the diameter of the cylindrical seat 15 and making it possible to thread the roller 20 onto the end of the spacer screw 4, in abutment against the flange 8, and to block it by the flange 14 of the roller fixing screw 12.
