Definitions

  • the present invention relates to a permanent shaft - hub connection, in particular for gear wheels on a gear shaft, each gear wheel being fastened on the shaft by means of a shrink fit, according to the preamble of patent claim 1.
  • Torque-transmitting shafts with gear wheels arranged on them are widely used in gear construction. There are a variety of options for fastening the gearwheels on the shaft. The types of this connection are divided into elementary shaft-hub connections and combined shaft-hub connections.
  • the form-fit elementary shaft-hub connections include the spline connection, the serration connection, the involute profile connection, the polygonal connection, the feather key connection and the pin connection.
  • the force-fit elementary shaft - hub connections include the press and shrink connection, the wedge connection, the clamping ring connection, the clamping disc connection and the star disc connection.
  • the integral elementary connections include the welded connection, the soldered connection and the adhesive connection.
  • the combined shaft - hub connections include a non-integral composite shaft - hub - Connections the press - knurled connection and the press point connection.
  • the non-material-integral shaft-hub connections include the press-adhesive connection, the press-press-solder connection and the press-weld connection.
  • soldered-welded connection is one of the integral cohesive shaft-hub connections.
  • a connection of a gearwheel with a rotating shaft for torque transmission by means of a shrink fit without an additional form-fitting component, be it a feather key, driving teeth or a pin (also called shrink fit) is used not only in gearboxes for motor vehicles, but in general in a variety of machines.
  • DE-A-198 50 383 describes a hydrodynamic retarder, which is arranged downstream of a transmission in a motor vehicle and which has a rotor arranged in a retarder housing, and a stator arranged in the retarder housing, which is arranged over a
  • Locking device is supported on the housing.
  • a measuring device for the retarder braking torque is provided on the housing, which is acted upon by the locking device, the measuring device being connected to a control device.
  • the measuring device on the retarder housing can be designed as a reaction cam that device directly applied or a stator projection in the housing, which is attached by means of a shrink fit.
  • DE-A-101 34 245 describes a transmission with an internal power distribution, which consists of a large gear wheel connected to an input shaft or to an output shaft, which is surrounded by a large number of pinions, the pinions of which mesh with it and that can be used both as a transmission and a reduction gear.
  • a shrink disk is provided to transmit the torques of the rotor shaft in a hollow gear shaft.
  • the gearbox is particularly suitable for driving generators through the rotors of wind turbines.
  • the object of the present invention is to create a permanent shaft-hub connection, in particular for the gearwheels on a transmission shaft, with which the torque transmission capability is considerably increased.
  • the invention therefore provides that gearwheels arranged directly next to one another on the shaft are designed such that they partially overlap and that the overlapping adjacent regions of the gearwheels are also connected to one another via a shrink fit.
  • the overlapping regions of the toothed wheels arranged next to one another are advantageously designed in a step-like manner.
  • the torque transmission capacity of the gears connected to one another by means of the shrink fit can be increased considerably, since the additional shrink fit connection between the gears leads to a radial reinforcement of the hub of one of the gears and thus reduces their expansion.
  • Another advantage of the configuration according to the invention is that the bending stiffness of the shaft is increased overall.
  • a gearwheel 2 On the shaft 1 of a gearbox, which is particularly but not exclusively a gearbox for a motor vehicle, a gearwheel 2 is arranged by means of a shrink fit 3, that is, firmly connected to it.
  • a second gear 4 which in the selected example is designed as a double gear, is arranged directly next to the gear 2 and is also fixedly connected to the shaft 1 via a shrink fit 5.
  • the gearwheels 2 and 4 are now designed in such a way that overlapping regions arise which are also connected to one another by means of a shrink fit 6. As can be seen from the figure, the overlapping regions are advantageously stepped.
  • the torque transmission capacity of the two gear wheels 2 and 4 can be significantly increased; the additionally provided shrink fit 6 firstly strengthens the hub of the gear 2 in the radial direction and thereby prevents or reduces its widening, as a result of which a portion of the shrink fit 3 is strengthened.
  • the two gears are coupled via the shrink fit 6, which contributes to increasing the torque transmission capacity.

Abstract

L'invention concerne une liaison arbre-moyeu durable notamment destinée à des roues dentées d'un arbre de transmission (1), chaque roue dentée étant fixée sur l'arbre au moyen d'un ajustage serré par retrait (3, 5). Des roues dentées (2, 4) directement voisines sont conçues de manière à se chevaucher partiellement, les zones voisines des roues dentées (2, 4) étant également reliées par l'intermédiaire d'un ajustage serré par retrait (6).
