Definitions
- the invention relates to a hydraulic unit according to the preamble of claim 1 and a device for fastening a hydraulic unit with a Additional unit according to the preamble of claim 14 (see e.g. EP-A-0 305 785).
- Hydraulic units in particular hydraulic motors of known type for driving for additional units, e.g. Grabs, excavators and other equipment, are known.
- these hydraulic units have a housing designed as a stator and a housing designed as a flange shaft Rotor on. Between the housing and a shaft section of the rotor are displacement elements which, when acted upon by a hydraulic fluid pressurize the rotor to rotate, and corresponding Bearings bearing axial and radial loads are provided.
- On a flange section is integrally formed on the shaft section of the rotor, whose diameter is larger than the diameter of the housing and on which the housing is slidably supported when the rotor rotates.
- The is called the rotor with the shaft section and the flange section is as Flanged shaft designed.
- the flange section In the area of the flange section, which Extending beyond the outer circumference of the housing are circumferential holes formed by which fasteners for appropriate fastening of additional units are provided. Because of the relatively large The diameter of the flange section of the flange shaft is the axial one The loads to which the hydraulic unit is exposed during use are limited.
- the shaft section is the flange shaft by in each case one end facing the housing and the flange section the inclined roller bearing arranged at the end.
- the bearings mentioned must be relatively large become, which leads to an enlargement of the drive unit.
- it is necessary to use other accessories such as larger masses, which consequently have a higher tensile load cause the hydraulic unit to use another hydraulic unit, which is able to withstand these higher axial loads to take up their correspondingly large-sized bearings.
- the hydraulic unit according to the invention has a rotor, a stator, which forms the housing, and displacement elements, which between Rotor and housing are arranged and which one accordingly below Pressurized hydraulic fluid is supplied to the rotor of the hydraulic unit to rotate.
- a bearing that absorbs axial and radial forces.
- the rotor is with a shaft section and a flange section as a flange shaft trained, which is used to attach additional units.
- the diameter the flange section is larger than the housing diameter, so that the flange section protruding beyond the outer circumference of the housing forms an area through which fasteners can be passed, which serve to attach an additional unit to the hydraulic unit.
- a support ring can be detachably connected to the flange shaft, which is with an inner shoulder on an outer shoulder on the housing supports to form a sliding area.
- This support ring is by means of Fasten with the flange section of the additional unit Flanged shaft and the additional unit connected. That is the support ring rotates together with the rotor.
- the housing has an outer shoulder and the support ring has an inner shoulder and both shoulders work together, the axial load by the additional unit not only from the flange section of the rotor, but also taken up by the housing itself. Those that slide together with the rotor when the support ring rotates Surfaces thus form a sliding area, which of the recording of axial loads as well as radial loads.
- a major advantage of such a support ring is that a hydraulic unit according to the invention due to the axial loads the force distribution in the flange section of the flange shaft and in the Housing can be increased. Furthermore, it is through the inner shoulder on the support ring and the outer shoulder on the housing possible, on the arranged flange-side end of the shaft section of the flange shaft Completely dispense with the inclined roller bearing. This leads to another Simplification of the construction of such new hydraulic units.

- the support ring runs with at least slidably around an inner surface on an outer surface of the housing. According to this embodiment is supported when rotating the rotor Mounted support ring at least part of the inner surface, which the The outer circumference of the housing faces, sliding around the housing. It is also according to another preferred embodiment possible that an O-ring between the inner surface and the outer surface is arranged.
- the flange section has the flange shaft on its side facing the housing an annular step on which the housing with an essentially congruent shape Sliding supports.
- This additional ring step in the area of Flange section of the flange shaft is used to bear radial loads on the hydraulic unit connected to an additional unit, which e.g. by lateral impact on obstacles, walls, etc. may occur.
- a seal acting O-ring can be provided. Such an O-ring prevents hydraulic fluid, with which the hydraulic unit is driven, from the interface, i.e. emerges from the sliding area of the housing at the flange section.
- the outer diameter of the Support ring substantially equal to the outer diameter of the flange section the flange shaft, so that the outer surface of the support ring in is substantially flush with the outer surface of the flange portion.
- the entire support ring is preferably made from a plain bearing material, which can preferably also be self-lubricating.

- the sliding area there can either be a separate sliding bearing to be lubricated be provided. or it can according to the embodiment listed above the support ring consist entirely of sliding material.
- a check valve is preferably arranged in the lubricant line. Such a check valve prevents the immediate hydraulic unit with the displacement elements and the bearing from being damaged in the event of pressure surges which may occur during operation.
- the storage of the Shaft section only at its end region projecting into the housing an axial and radial load bearing.
- the support ring is sufficiently large Has inner shoulder, which is dimensioned with a sufficiently large
- the outer shoulder of the housing interacts, and if the Flange section of the flange shaft has an annular step. This can both the support ring and the flange section of the flange shaft itself absorb increased radial and axial loads, so that the Flange section facing bearings of the shaft section of the flange shaft can be dispensed with.
- the device which the attachment of a hydraulic unit with an additional unit, one Support ring, which forms with a rotor of the hydraulic unit Flange shaft is releasably attachable and includes an inner shoulder, the Inner shoulder with formation of a sliding area on an outer shoulder of the Housing is supported.
- the hydraulic unit is in particular a hydraulic motor, and the additional unit is in particular a gripper.
- a major advantage of this support ring according to the invention is that both increased axial and radial loads not only in the Flange section of the flange shaft, but also in that Housing can be initiated.
- its connectable axial load and its radial load that can be absorbed during operation can be increased without the Hydraulic unit must be replaced even with these increased loads.
- the inner shoulder of the support ring and the outer shoulder inclined to each other, the angle of inclination to a substantially extending radially to the longitudinal axis of the shaft section of the flange shaft Level for the inner shoulder and the outer shoulder essentially is equal to. This inclined arrangement of the inner shoulder and the Outer shoulder can withstand both axial and radial loads Support ring are introduced into the housing of the hydraulic unit.
