Definitions

  • the invention concerns the technology of the mechanisms for the motion transmission from an hydraulic motor to milling rotating tools, included in the international classification E01 c.
  • Figure 1 is a view of the extractable transmission shaft that transmits the torque from a central hydraulic motor with two milling side drums.
  • Figure 2 is a view of an extractable transmission shaft that transmits the torque from a central hydraulic motor to a single side milling drum.
  • Figures 1 and 2 highlight the simplicity of execution of the transmission shaft that is inserted and extracted with surprising simplicity just because its only function is to transmit the torque of the hydraulic central motor without bearing any other stress that milling drums are likely to encounter during heavy excavation operations.
  • Figure3 is a schematic section of the rotor of an hydraulic motor that can be applied to a frame structure of an operator machine. It can be noticed a central groove 2 where the grooved shaft, that transmits the torque of the hydraulic motor without suffering any milling related stress, is inserted and extracted.
  • Figure 4 is an axis section of a support for a milling drum. It can be noticed the central grooves of the drum in which can be inserted and extracted the grooved shaft that transmits to the milling drum only the torque of the hydraulic motor but it does not suffer the other stresses caused by the heavy milling conditions.
  • Figure 5 is an axis section of the side supports applied to the frame structure through the connecting bolts.
  • Figure 5 presents a case where in the axial grooves of the side drums and of the hydraulic central motor can be inserted and then extracted the grooved shaft that transmits the torque to the milling drums held by the supports bolted to the frame structure. It can be noticed that the grooved shaft it is not yet assembled or it has already been extracted.
  • Figure 6 presents a grooved shaft already inserted in the groove of the side drums and in the main groove of the hydraulic motor.
  • Figure 7 represents a version of the invention with a single side drum. It can be noticed that the grooved shaft it has not been inserted yet or it has been already extracted from the central groove.
  • Figure 8 represents the same version of figure 7 with the grooved shaft already inserted in the relative grooves.
  • Figure 9 schematizes an external view of the application of two side drums.
  • Figure 10 schematizes an external view of the application of a single drum.
  • Figure 11 is a three-dimensional representation of the application of two side drums.
  • Figure 12 schematizes a side view of the application of the milling machine at the edge of an operator arm of a machine.
  • FIG. 13 schematizes in perspective a milling head with two side drums. In the figures each single detail is marked as follows:
  • 1 is a grooved shaft that can be inserted and extracted in the groove rotor of an hydraulic motor.
  • 3 is the inner groove of the hub of a milling drum.
  • 5 is a support that is bolted to a frame central structure.
  • 11 is a partially grooved shaft for the version with a single side drum.
  • the extraordinary resistance of the device object of the present invention is of course obtained by the characteristic separation of two kinds of stresses. Only the torsion stresses for the transmission of the motor torque of the hydraulic motor are absorbed by the grooved shaft inserted in the central rotor while the other stresses are absorbed by the frame structure through the bolted side supports.
  • the invention of course allows for several variations of practical realization as far as the dimensioning and the structural proportioning are concerned and for the technological choices of the material for the realization of the details. All the milling machines having a central transmission shaft, grooved and extractable, with the characteristics as fundamentally illustrated, described and hereinafter claimed, will be held as being part of protection sphere of the present invention.

Abstract

Cette invention concerne une fraiseuse hydraulique pour pelles hydrauliques caractérisée en ce que l'arbre d'entraînement (1) assurant la transmission de couple entre le rotor à arbre cannelé (2) du moteur hydraulique central et le tambours de maintien (4) de la tête de fraisage est soumis uniquement aux efforts de torsion du fait que toutes les autres contraintes dynamiques qui s'exercent sur les tambours sont amorties par les supports (5) fixés sur la structure.
