Abstract
A hydraulic milling machine for excavators characterized by the fact that the driving shaft (1) for the transmission of the torque from the grooved rotor (2) of the central hydraulic motor to the milled tool holding drums (4) is subject only to the torsion stress since all the other dynamic stresses on the drums are dumped on the supports (5) fixed on the frame structure.
Description
- The present invention concerns the technology of the mechanisms for the motion transmission from a hydraulic motor to milling rotating tools.
- Employment of a hydraulic motor to activate rotating operating tools and in particular in milling machines that operate on stony compact materials is known. The known equipment, besides transmitting the necessary torque to operate the heavy milling operations, must also bear the bending stress and shocks caused by the rapid impact of the tools against the rocky walls and surfaces. The bending stress is increased by the fact that the milling drums are assembled overhanging on the motor shaft in order to perform penetrations in the rocky walls.
- Such operational needs have demonstrated that the motor shaft is often not able to bear for long the combined effect of the heavy stresses during the milling operations. The problem to be solved is to increase the overall resistance and the life of the transmission components.
- Accordingly, it is a general object of the invention to provide an optimal solution for the problems that still affect this field of technology.
- A specific object of the present invention is to provide a hydraulic milling machine for excavators that has smaller dimensions, is more economic to operate and is more convenient during maintenance operations than other known machines.
- Another object of the invention is to provide a hydraulic milling machine for excavators comprising supports (5) fixed onto a frame structure (7), at least one milling drum (4) supported by the supports (5) and by bearing (10), and a hydraulic motor (12) mounted on the frame structure (7). The hydraulic motor (12) further comprises a rotor (2) with a grooved shaft (1) driven by the hydraulic motor such that the grooved shaft (1) is directly connected to the milling drum (4) and the grooved shaft (1) directly drives the milling drum (4). The motor is subjected only to the torsion stress since all other dynamic stresses on the drums are dumped on the supports (5).
- Another more specific object is to provide a hydraulic milling machine where the grooved shaft (1) directly drives the milling drum (4) by means of axial grooves (11) having axial grooves compatible with the grooved shaft. The shaft may be partially grooved for the invention embodiment with a single side drum or may have grooves the same axial length of the grooved shaft for the invention embodiment with two milling side drums.
- Another more specific object is to provide a hydraulic milling machine for excavators where the grooved shaft (1) can be readily inserted and extracted from the rotor (2) of the hydraulic motor.

- FIG. 1 is a view of the extractable transmission shaft that transmits the torque from a central hydraulic motor with two milling side drums.
- FIG. 2 is a view of an extractable transmission shaft that transmits the torque from a central hydraulic motor to a single side milling drum.
- FIGS. 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.
- FIG. 3 is a schematic section of the rotor of a hydraulic motor that can be applied to a frame structure of an operator machine. As seen in the figure, a
central groove 2 is present where the grooved shaft, that transmits the torque of the hydraulic motor without suffering any milling related stress, is inserted and extracted. - FIG. 4 is a cross section of a support for a milling drum. As seen in the figure, the grooved shaft can be inserted and extracted from the central grooves of the drum. The grooved shaft 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 the central grooves of the drum.
