Definitions
- the present invention relates to a centrifuge for cleaning a liquid, in particular the lubricating oil of an internal combustion engine, with a housing, with at least one housing-side bearing means and a rotor rotatably mounted thereon, which is formed at least in two parts and an inner part serving for the storage and a dirt collection in a dirt collecting portion serving a dirt collecting portion, wherein for the purpose of maintenance of the centrifuge, the waste collecting part is detachable from the inner part.
- Centrifuges of the aforementioned type have been known in principle for many decades and are used in various applications, an application being the cleaning of the lubricating oil of internal combustion engines. Especially in this and in many other applications, the centrifuge is a machine component that is both possible to produce inexpensive and on the other hand should have a good efficiency with high durability.
- the rotor of the centrifuge is mounted by means of two such bearings on the housing-side bearing means. If a bearing is designed as a sliding bearing, at least one separately manufactured bearing sleeve must be installed in the centrifuge, this bearing sleeve either on the housing side bearing means or in the rotor installed, for example, up or pressed must be.
- two slide bearing sleeves are to be installed, in which case a first slide bearing sleeve is then applied to the housing-side bearing means and a second slide bearing sleeve is to be installed in the rotor.
- the two plain bearing sleeves then together form the plain bearing. Since usually two plain bearings are used, in extreme cases, a total of four bearing sleeves must be manufactured separately and then mounted. If rolling bearings are used as an alternative, they must also be manufactured and installed separately. Obviously, the parts required to form the bearings give rise to a relatively high production and assembly effort, which has a noticeable effect on the overall manufacturing costs of the centrifuge.
- That the inner part is an integral part of a second bearing material and has one or more second sliding bearing surfaces
- the rotor is mounted rotatably directly on the housing-side bearing means, in other words without the interposition of sliding bearing sleeves or bearings or other separate bearing components.
- Slide bearing sleeves or roller bearings or the like separate bearing components are no longer needed in the centrifuge according to the invention for the storage of the rotor.
- This also eliminates the costs associated with the manufacture and assembly of the bearing sleeves or bearings or the like separate bearing components, which saves time and costs in the manufacture of the centrifuge.
- high efficiency and a long service life of the centrifuge are ensured because, due to the use of suitable bearing materials which form mutually bearing-compatible plain bearing material pairings, low bearing friction with low bearing wear is achieved even without separate bearing components.
- the centrifuge according to the invention advantageously the tolerance chains are smaller, resulting in particular to an improved balancing and thus to a higher rotational speed of the centrifuge with the same drive power.
- the dirt trap part is connected to the inner part to the rotor and the waste collecting part for its disposal or cleaning of the inner part with the whereabouts of the inner part on the housing side storage means separable.
- the dirt collecting part can be removed together with the dirt collected therein during maintenance of the centrifuge from the housing and replaced by a fresh dirt catching part, while the inner part remains permanently in the centrifuge.
- the storage of the rotor is thus charged in the maintenance process in any way or exposed to a risk of contamination.
- the use of a more expensive material for the inner part is justified because it is not replaced during maintenance of the centrifuge, but remains permanently in the centrifuge.
- the inner part of the rotor is designed as a drive part with at least one radially outwardly pointing nozzle arm with at least one recoil nozzle.
- the inner part is expediently a life-time component of the centrifuge, which for this reason is already made of a suitably durable material in order to ensure the necessary durability.
- the dirt-catching part of the rotor is designed as a drive part with at least one recoil nozzle.
- the inner part is expediently a lifetime component of the centrifuge, which also here the advantages stated in the preceding paragraph can be achieved.
- new replacement nozzles are used with each replacement of the dirt trap part.
- the inner part is expediently a casting-produced part of the second bearing material.
- the invention further preferably proposes that an axis projecting into the inner part or passing through the inner part is arranged in the housing, forming the housing-side bearing means, and that the inner part comprises a central tubular body which surrounds the axis.
- the axis forming the housing-side bearing means is a rotary or rotary-milling part of the first bearing material.
- the axis can thus be completely manufactured and processed in automatic processing machines, which allows a more cost-effective production in large quantities.
- the housing-side bearing means forming the axis on its outer circumference and on the other hand, the central tube Body are surface-treated on its inner circumference in at least one area to at least a direct mutual bearing fit.
- the bearing of the rotor on the housing side bearing means for.
- the axis instead, with the number and the arrangement of the areas of direct mutual bearing fit according to the boundary conditions of the particular application of the centrifuge, such.
- mass of the rotor and / or externally acting on the centrifuge mechanical loads, such as vibrations of an internal combustion engine or shocks from a moving vehicle.
- two axially spaced apart from each other in the rotor areas of immediate mutual bearing fit are provided and that in other areas of the outer periphery of the housing-side bearing means forming the axis and the inner circumference of the central tubular body have radial distance from each other.
- the areas of direct mutual bearing fit are expediently carried out so that they are on the one hand as large as necessary to ensure adequate durability, and on the other hand, they are as small as possible to keep the processing costs low and the smoothest possible mounting of the rotor to achieve.
- a first region of the immediate mutual bearing fit is also provided at or near a first axial end of the rotor and a second region of the immediate mutual bearing fit is provided at or near a second axial end of the rotor.
- the greatest possible distance of the areas of the immediate mutual bearing fit ensures a relatively low Load of the individual storage areas under given external conditions, which contributes to a good durability of the centrifuge.
- bearing materials are metallic materials or plastic materials or plastic-metal composites.
- first bearing material preferably be a steel and for the second bearing material to be a supereutectic aluminum-silicon alloy or a bronze or a bronze alloy.
- the housing-side bearing means is then expediently made of steel and can be made inexpensively from a semi-finished by machining.
- the aluminum-silicon alloy or bronze or bronze alloy can be processed conveniently in die casting and is therefore expediently used for a casting production of the rotor or its inner part or its central tubular body.
- the plastic-metal composite materials are plastics with metal particles embedded therein. These composites combine light weight with good storage properties and good durability.

- both the pivot bearing and the thrust bearing carried only sliding, for which simple and inexpensive elements are used.
- the dirt-trapping part of the rotor preferably consists partly or entirely of plastic.
- plastic for the dirt trap part of the rotor leads to a lower overall weight of the rotor and also allows an advantageous easy disposal of dirt-loaded part after maintenance of the centrifuge, because with a suitable selection of the plastic, the waste collection part is completely thermally recoverable.
- the housing-side bearing means is hollow over at least part of its axial length and that in the channel thus formed in the interior of the housing-side bearing means a minimum - pressure valve is arranged, the liquid flow through the centrifuge until it exceeds a Minimum fluid pressure releases.
- the minimum pressure valve is space-saving in a easily loadable with a higher fluid pressure part of the centrifuge, namely housed in the housing side, stable storage means.

- the upper end of the axle 12 is formed by an upper axle end piece 12 'which is screwed to the remaining axle 12 and which in turn is centered with its upper end in a centering recess 16 on the underside of the cover 15.
- a freely upwardly projecting axis 12 can be used, which experiences no centering support on the lid 15.
- the rotor 10 of the centrifuge 1 here consists of two parts, namely an inner part 2 and a waste collecting part 3.
- the inner part 2 consists essentially of a central tubular body 20 which is arranged concentrically to the axis 12 and surrounds it. From a lower region of the tubular body 20, two nozzle arms 21 extend in the radial direction obliquely outwards and downwards, opposite one another. At the radially outer end of each nozzle arm 21, a respective recoil nozzle 22 for driving the rotor 10 is arranged by means of a liquid flow. Thus, here forms the inner part 2 of the rotor 10 whose drive part.
- the dirt trap part 3 is mounted in the axial direction from above on the inner part 2 and connected thereto via provided at the upper end of the rotor 10 connecting means 32 so that an automatic relative movement in Axial direction between the dirt trap part 3 and the inner part 2 is excluded.

If necessary, but can be removed and replaced by a new inner part 2 after removing the upper Achsendrioss 12 'and the inner part 2, if this should unexpectedly be necessary.
- the axis 12 on the one hand and the inner part 2 on the other hand consist of materials, such as metallic materials or composites, which form mutually bearing-compatible plain bearing material pairings. All other parts of the centrifuge 1 that are not involved in the storage can be made of other materials, regardless of their suitability for storage.
- the other material may, for example, be plastic, whereby a Ringes weight and ease of manufacture can be achieved.
- the dirt trap part 3 can then be utilized thermally in its design made of plastic with a suitable choice of material together with the dirt deposited therein, without leaving metallic individual parts.
