  • An operative connection is, a pin which is arranged parallel offset to the axis of the second gear and which rotates about this axis when the second gear rotates - a piston with a piston rod which is connected to the pin such that in a Rotation of the second gear of the piston moves up and down, a balance weight that compensates for the mass forces of the reciprocating piston.
  • Such a compressor for a puncture set is e.g. from the German
  • the second gear includes a central circular hole with which it is rotatably mounted on a hollow shaft which is fixedly connected to the housing of the drive motor.
  • the balance weight includes an axis which is guided centrally through the hole in the second gear and through the housing-fixed hollow shaft and rotatably supported there.

  • the second gear has a plurality of positioning pins, with which the balance weight is positioned in a certain position to the second gear.
  • the known from the cited document compressor has a compact construction, since the second gear and the balance weight in the longitudinal direction of the compressor are arranged directly one behind the other.
  • the compressor has a complex structure.
  • it must be ensured that the second gear and the balance weight match each other, so that the balance weight can be positioned without play between the positioning pins of the second gear, as it could otherwise come to desired noise in the operation of the compressor.
  • the balance weight does not always optimally balance the mass forces of the piston.
  • the invention has for its object to provide a compressor for a tire puncture set, which has a low noise and with which the mass forces of the piston can be optimally balanced.

  • An advantage of the invention lies in the fact that between the second gear and the balance weight no clearance can exist, since the balance weight is an integral part of the second gear. Another advantage of the invention is the fact that the balance weight is securely fixed relative to the second gear in a certain position, so that the mass forces of the piston moving up and down can be optimally balanced. Another advantage of the invention is the fact that The compressor can be easily manufactured, since the second gear and the balance weight can consist of a single component and thus reduces the number of parts.
  • the pin and the axis of the second gear are part of the second gear and permanently connected thereto.
  • the second gear on a recess which is arranged in a ring around the axis.
  • the bearing of the axle, with which the second gear is supported formed as a ball bearing or roller bearings.
  • the second axis is formed as a hollow shaft and connected to the bearing of the axle such that the second gear is secured in the axial direction.
  • the advantage of this development is the fact that the axial securing of the second gear can be accommodated to save space in the hollow shaft.
  • the connection of the axle with the bearing by means of a screw which is inserted into the hollow axle, or by crimping of the hollow shaft.
  • the advantage of using a screw is the fact that it can be easily solved (eg to replace the gear).
  • the advantage of a flanging is the fact that no separate component is needed to make the connection.
  • the pin is designed as a hollow pin, with which the piston rod is connected such that the piston rod is secured in the axial direction.
  • connection is made by means of a screw which is inserted into the pin or by crimping the pin.
  • the second gear is formed as a pot with an outer pot and an inner pot, wherein in the outer pot, the balance weight is arranged - on the bottom of the inner pot, the axis is concentrically mounted on the bottom of the pot of the pin is arranged.
  • the advantage of this development is the fact that the second gear has a compact design and yet the balance weight, the axis and the pin can be incorporated to save space in the second gear.
  • the second gear is produced by casting.
  • the advantage of this development is the fact that the second gear in the casting process in large quantities can be easily and inexpensively.
  • Another advantage of this development is the fact that the second gear in the casting process are easily formed as a single component can.

  • the drive motor 4 of the compressor 2 drives a first gear 6, which is in engagement with a second gear 8.
  • the second gear 8 includes an axle 10 which is formed as a hollow axle.
  • the second gear 8 includes a pin 22 which is arranged offset parallel to the axis 10 of the second gear 8 and which rotates about the axis 10 when the second gear 8 is driven by the drive motor 4 and the first gear 6 and rotates.
  • the piston rod 24 of a piston 26 is connected such that upon rotation of the second gear 8, the piston 26 in the cylinder 28 of the housing-mounted attachment 12 moves up and down.
  • the pin 22 is exactly like the axis 10 part of the second gear 8 undetachably connected thereto.
  • the pin 22 is formed as a hollow pin, so that the piston 26 can be secured with its piston rod 24 in the axial direction against deduction.
  • the backup takes place in the illustrated embodiment by means of a screw 18 which is screwed into the hollow pin 22, wherein between the screw head and hollow shaft 22, a washer 20 which rests against the end face of the pin 22 and at the lower end of the piston rod 24.
  • the backup can also be done by crimping the end of the hollow pin, which faces away from the drive motor 4.
  • the compressor 2 includes a balance weight 30, which is an integral part of the second gear 8 and is inextricably linked thereto (see Fig. 2 closer). With the balance weight 30 are the Mass forces of the piston 26 moving up and down balanced. In the embodiment shown in Fig. 1, the balance weight 30 is accordingly at the lower end of the compressor, since the piston 26 is just at its top dead center.
  • FIGS 2a to 2c show the second gear 8 in different views.
  • a cross section through the second gear 8 is shown.
  • the second gear 8 consists of a pot 32, which is divided into an outer pot 34 and into an inner pot 36, which are arranged concentrically to one another.

  • the teeth 44 of the second gear 8 are arranged, which engage in the teeth of the first gear 6 (see Fig. 1).
  • the axis 10, the pin 22 and the balance weight is permanently connected to the second gear 8. This can be done in a simple manner by the second gear 8 is made with the said components in the casting process.
  • FIG. 2b shows a plan view of the pot as seen from the side of the axis 10.
  • FIG. 2b shows that the inner pot 36 of the pot 32 is subdivided into a plurality of segments 36.1 to 36.7, the balancing weight 30 being located in the segment 36.7.
  • Fig. 2c shows a plan view of the pot 32 from the side of the pin 22. Since the bottom 42 covers the entire base of the pot 32, in Fig. 2c only the bottom 42, the teeth 44 and the pin 22 can be seen.

Abstract

Compresseur (2) pour un kit de réparation de crevaison de pneu, qui comporte une seconde roue dentée (8) pourvue d'une partie saillante (22). Ladite partie saillante (22) se trouve en liaison fonctionnelle avec un piston (26) de manière telle que ce dernier opère un mouvement de va-et-vient en cas de mouvement de rotation de la seconde roue dentée (8). Les forces inertielles du piston (26) opérant un mouvement de va-et-vient sont compensées à l'aide d'un contrepoids (30) qui fait partie intégrante de la seconde roue dentée (8) et qui est fixé à demeure sur cette dernière.
