Definitions
- the present invention relates to a hydraulic milling machine for attachment to the Equipment of a construction or mining machine, with at least one Cutting roller, at least one flywheel for receiving kinetic Energy and at least one hydraulic motor for rotary Driving the cutting roller and the flywheel.
- Such hydraulic milling machines are versatile. So they become, among others for the demolition of structures, for the creation of ditches, for the drifting of roads or used in over and underground mining. For the respective The use of hydraulic milling machines in different performance classes and with offered suitable tooth fillings.
- a generic hydraulic tiller for attachment to the bucket equipment of a standard excavator is from the US 6,438,874.
- the router works in inhomogeneous material. This can be about in Boundary areas of different rock strata or during dismantling of reinforced concrete to be the case.
- the Tiller exposed to sudden loads, which their driving torque can exceed; In this case, threatens to block the router.
- the rotating cutting roller should be as high as possible Have moment of inertia. This gives the rotating cutting roller a high kinetic energy, which helps you to overcome resistance peaks is helpful.
- the installed drive power of the mill can thereby comparatively low.
- the aforementioned patent teaches, among other things, the moment of inertia of To increase cutting roller thereby that on its inside flywheel masses to be ordered.
- the disadvantage of this solution is that with the Moment of inertia of the cutting roller and the total mass of the hydraulic cutter disproportionately increases. This is in the present application example the usable working area of the mill is reduced because the stability of the mill Baggers must always be guaranteed even at full load.
- Object of the present invention is therefore to a hydraulic milling machine create their cutting roller moment of inertia in a favorable ratio to the total weight of the hydraulic cutter stands.
- the rated speed of the hydraulic motor is correct at which this achieved a good efficiency, not with the desired Speeds of the flywheel or the cutting roller match. Therefore, the Flywheel or the cutting roller generally not directly are driven. So is usually next to the first gear, which Cutting roller and flywheel connecting, another gear necessary which connects for example motor and cutting roller.
- the hydraulic milling machine proposes a development of the invention, both transmissions in a transmission integrate and so does the angular velocity of the hydraulic motor in fixed relationship to those of the cutting roller and the flywheel too put.
- the supporting structure of the hydraulic mill 0 forms a housing 1, in which the entire drive train is housed.
- Core of the powertrain forms Transmission 2, which has a drive 3 and two outputs 4, 5.
- the Drive 3 of the hydraulic cutter 0 via two hydraulic motors 6, which are arranged coaxially on a common motor shaft 7. Also on arranged this motor shaft 7 is a drive wheel. 8
- each of the neighboring wheels 9, 10 establishes a Stirnradzug which ends at one of the two outputs 4, 5 respectively.
- the first Output 4 is associated with a cutting roller 11, the second output 5 a Flywheel 12.
- the cutting roller 11 is composed of two half-shells 11 a, 11 b, the on both sides of the housing 1 on a common cutting roller axis thirteenth are arranged. On the outside of the half-shells 11a, 11b are located Teeth 14, their texture and geometrical position and alignment directed according to the intended use of the hydraulic cutter 0.
- the flywheel is composed of two sub-masses 12a, 12b, the on both sides of the transmission 2 on a common flywheel mass 15 are arranged.
- the flywheel mass axis 15 is with a toothing provided, which serves as flywheel output gear 17.
- the Stirnradzug starting from the left neighboring wheel 9 consists only of a tooth pairing between the first adjacent wheel 9 and a Cutting roller driven gear 16.
- the cutting roller driven gear 16 is central arranged on the cutting roller axis 13 and takes the drive torque of Hydraulic motors 6 for the cutting roller 11 against.
- the translation of the Getriebes 2 between the drive 3 and the output 4 of the cutting roller 11th is slightly less than one in this example.
- the engine speed is Accordingly, reduced in the direction of the cutting roller 11, the torque elevated.
- the translation between the drive 3 and the Downforce 5 of the flywheel 12 takes place via three stages, by the second Neighboring wheel 10 meshes with a pinion 18 on an intermediate shaft 19 and turn the wheel 20 of the intermediate shaft 19 with the flywheel output gear 17 is engaged.
- the transmission 2 By the transmission 2, the angular speeds of the cutting roller 11, the hydraulic motors 6 and the flywheel 12 to each other in a solid Ratio sets, it provides a direct connection between the cutting roller 11th and the flywheel 12 ago. If the rotating cutting roller 11 through a shock loaded from the outside, this is along the drive train along the gears 16, 9, 8, 10, 20, 17 further given in the flywheel 12 and absorbed by the kinetic energy stored there.
