Compacting machine
The present invention relates to a compacting machine comprising a shaft, an unbalanced mass and a drum, wherein the shaft is connected both to the unbalanced mass and to the drum and is adapted to transfer imbalance forces from the unbalanced mass to the drum, and further wherein the shaft is mounted in a plain bearing.
1. A compacting machine, comprising:
at least one shaft;
an unbalanced mass; and
a drum,
wherein said at least one shaft is connected to both the unbalanced mass and the drum and is adapted to transfer imbalance forces from said unbalanced mass to said drum,
wherein said at least one shaft has at least one exciter bearing, in which the unbalanced weight rotates during vibration operation, and that the at least one exciter bearing is a plain bearing.
2. The compacting machine according to claim 1 , wherein said plain bearing is adapted to absorb imbalance forces and driving forces.
3. The compacting machine according to claim 1 , wherein said compacting machine comprises a drive complying with the principal of a hydraulic geared engine, that said drive comprises a housing and a driving shaft and is adapted to transfer vibration to said drum and that said unbalanced mass forms part of said drive.
4. The compacting machine according to claim 3 , wherein said drive comprises a first gear wheel, a second gear wheel, a first shaft and a second shaft, that said first gear wheel is connected to said first shaft and said second gear wheel is connected to said second shaft, that said first gear wheel engages said second gear wheel, that said first shaft is connected to said driving shaft and the axis of said second shaft is not in alignment with the axis of said driving shaft.
5. The compacting machine according to claim 1 , wherein said drive, said at least one shaft and said plain bearing are combined to form a subassembly.
6. The compacting machine according to claim 3 , wherein said drive comprises a toothed clear system in communication with said plain bearing, such that oil used for said drive of said hydraulic geared engine passed on to said plain bearing for lubrication of the plain bearing.
7. The compacting machine according to claim 1 , wherein a space in which the plain bearing is disposed is capable of being completely filled with oil.
8. The compacting machine according to claim 1 , wherein a space in which said plain bearing is disposed comprises both an influent duct and an effluent duct, such that said plain bearing is adapted to be located in a flow of oil and heat from said plain bearing can be dissipated via said flow of oil.
9. The compacting machine according to claim 1 , wherein said compacting machine comprises two or more shafts of which the rotational speed and/or position can be regulated so as to set a direction of vibration.
10. The compacting machine according to claim 9 , wherein a detector and an indicator are provided, wherein said detector is adapted to detect the position and/or rotational speed of a shaft and to forward the acquired data to said indicator.
11. The compacting machine according to claim 10 , wherein software is provided, which is adapted to process the position and/or rotational speed detected by said detector and to control the drives in an appropriate manner.
