- the separator plates are provided with mutually aligned openings.
- the rotor shaft and thus the centrifugal rotor are driven via a turbine wheel, which is arranged in the drive chamber and is subjected to an oil jet in operation. Due to the rotational movement of the centrifugal rotor and introduced in the central region of the engine oil-gas mixture is set in rotation and conveyed radially outward. It flows through the conical outflow areas.
- a sealing ring for a centrifugal separator is known from US 6,676,131. 0 This has advantages in terms of installation and a good fixation in a groove receiving the sealing ring.
- the housing partition wall has a bearing bush in which a bearing, in particular a ball bearing, is received for supporting the rotor shaft.
- the bearing bush is integrated in the housing partition.
- the bearing bush may have a pipe socket which projects to the drive chamber.
- This tube approach can be used advantageously for the realization of the labyrinth seal.
- the labyrinth seal has a sealing disc with a circumferential axial groove and that a free end of the pipe socket in the axial groove, preferably non-contact engages.
- the sealing disc is rotationally coupled to the rotor shaft.
- the labyrinth seal is thus formed in this embodiment of the invention between the housing-fixed pipe socket and the rotating rotor shaft. The invention thus avoids sealing parts that rotate with one another in operation with a contact seal that is prone to wear.
- the drive device has a drive wheel which can be driven fluidly, preferably a fluidically impinged turbine wheel, which is mounted in a rotationally fixed manner on the rotor shaft and coupled to the sealing disk.
- a drive wheel which can be driven fluidly, preferably a fluidically impinged turbine wheel, which is mounted in a rotationally fixed manner on the rotor shaft and coupled to the sealing disk.
- other types of drive devices such as running in an oil bath chain drive or the like.
- the sealing washer between the drive wheel and bearing is arranged.
- the sealing disc has a radial region of greater thickness, which contacts an inner ring of the bearing. As a result, the sealing disc can be used at the same time for bracing the bearing.
- the invention further relates to a sealing arrangement in a device of the type described above, comprising a labyrinth seal which seals non-contact the separator chamber of the drive chamber.
- FIG. 1 shows an axis-containing section of a device according to the invention
- Fig. 2 is an enlarged view of the designated in Fig. 1 with II area and
- FIG 3 shows a cross section through a sealing washer according to the invention.
- a centrifugal separating device according to the invention is shown in a section containing the longitudinal axis A and generally designated 10.
- the separating device 10 comprises a housing 12, which encloses a separator chamber 14.
- the housing 12 is designed to be open at the bottom and closed by a housing-side wall 16 at the bottom.
- the housing is provided with an inlet nozzle 18, which defines an inlet 20 opening into the separator chamber 14.
- the housing 12 further has an outlet, not shown.
- the housing 12 holding webs 22 and 24 which receive a bearing cup 26 and hold in the housing 12.
- the bearing cup 26 is stepped and includes apertures 28 such that the inlet 20 is fluidically connected to the separator chamber 14.
- a ball bearing 30 is rotatably taken up with its outer ring.
- the inner ring of the ball bearing 30 is pressed onto a rotor shaft 32.
- the rotor shaft 32 is also mounted via a further ball bearing 34 in the housing partition 16.
- the housing partition 16 has a central opening which is surrounded by an integrally formed tubular extension 36.
- the ball bearing 34 is pressed with its outer ring in the inner peripheral surface of the pipe extension 36 and is held at the lower end by a diameter constriction on the neck 36.
- the inner ring of the ball bearing 34 sits on the rotor shaft 32nd
- a plurality of frustoconical Abscheiderbleche 38 are arranged at regular intervals and rotatably mounted on the rotor shaft 32.
- the separator plates 38 also have openings 40 in their horizontally extending central area. The rotor shaft 32 and the separator plates 38 together form a centrifugal rotor 39.
- a bottom part 42 is further arranged with a collecting channel 44 integrally formed therein.
- the collecting channel 44 is bounded radially on the inside by a circumferential channel wall 46 formed on the funnel bottom 42.
- an oil collecting basin 48 is formed between the bottom part 42 and the housing partition wall 16.
- the collecting duct 44 is connected to the oil collecting basin 48 via bottom-side drainage slots 50, which are distributed uniformly in the circumferential direction.
- a discharge opening 52 is provided for oil discharge.
- a drive chamber 60 is arranged below the housing partition wall 16, which is only partially shown.
- the rotor shaft 16 extends through the tube extension 36 in the drive chamber 60.
- a drive wheel designed as a turbine wheel 64 is mounted rotationally fixed.
- the turbine wheel 64 has at its upper end on turbine blades 66 which can be acted upon via a not shown in Rg. 1 and 2 nozzle with an oil jet, so that the turbine blades 66 on the oil striking the turbine wheel 64 and thus the rotor shaft 16 together with the attached Abscheiderbleche 38 in rotation about the axis A. Details of the arrangement in the region of the lower ball bearing 34 are also apparent from FIG.
- a sealing washer 70 made of steel or another dimensionally stable material is used.
- the sealing washer 70 is shown in a single part illustration in FIG. It has a central opening 72, which is bordered by a raised radial area 74.
- the raised radial region 74 serves to rest on the inner ring of the ball bearing 36.
- the underside of the sealing disc 70 is essentially planar.
- the sealing disc 70 has a circumferential groove 76 whose width B exceeds the wall thickness b of the lower free end of the tube extension 36.
- the lower free end of the pipe socket 36 protrudes contactlessly into the groove 76, so that a labyrinthine gap between the lower free end of the pipe socket 36 and the groove 76 is formed.
- the gap width is, for example, in the range of 0.01 mm to 0.20 mm.
- the turbine blades 66 of the turbine wheel 64 are irradiated with a fluid, preferably engine oil, under pressure, so that the turbine wheel 64 is rotated and drives the rotor shaft 32.
- the separator plates 38 rotate with the rotor shaft 32. They set the air in the central region of the centrifugal rotor 39 consisting of the rotor shaft 32 and separator plates 38 to rotate, so that it flows outwards due to the centrifugal action. This results in a negative pressure in the central region and an intake effect (see arrow P), so that an oil-air mixture is sucked in via the inlet port 18 from a crankcase of an internal combustion engine.
- the oil-air mixture contains oil particles that are to be separated from the air.
- the oil-air mixture passes through the openings 28 to the separator plates 38 and is rotated there. Part of the oil-air mixture flows through the apertures 40 down, the other part of the oil-air mixture moves due to centrifugal force radially outward and impinges on the conical regions of Abscheiderbleche 38. In this case, the divide in the oil-air Mixed oil droplets from the air and stick to the separator plates.
- the separated oil is delivered by the centrifugal force on the Abscheiderblechen 38 radially outwardly and finally thrown off at the radially outer edge, as shown in Fig. 1 at 54.
- an oil film 58 is formed which, due to gravity, flows downwards and collects in the collecting duct 44. From there, the separated oil can flow via the discharge slots 50 into the fluid collecting basin 48 and be led back into the oil circuit of the engine.
- the purified air separated from the oil particles flows out of the separator chamber 14 via the outlet, not shown, and can be released to the atmosphere.
- the sealing washer 70 is provided for the formation of the labyrinth seal. It has been found that the use according to the invention of the sealing disc 70 with the groove 76 and a contactless labyrinth seal resulting therefrom has considerable advantages over contacting seals, as shown, for example, in WO 2004/091799 A1. On the one hand, contact seals are subject to ever-increasing wear as the operating time increases, which can even lead to seal failure.
- the labyrinth seal according to the invention works without contact and is therefore not subject to any friction-related wear. Furthermore, in certain operating situations, in particular in a high-performance operation of the internal combustion engine, proportionally high pressures or pressure peaks may occur in the separator chamber, which must be reduced in the short term. In this case, a pressure reduction via the drain slots 50 and the discharge opening 52 is to be avoided, because otherwise the oil drainage process would be interrupted and under certain circumstances too much oil would remain in the separator chamber 14. This would lead to a deterioration of the separator effect.
- the invention now offers the advantage that a pressure reduction to the drive chamber 60 can take place via the labyrinth seal between the sealing washer 70 and the tube extension 36. Nevertheless, the labyrinth seal ensures a sufficiently good Sealing the separator chamber 14 from the drive chamber 60, so that in the drive chamber 60 existing oil droplets can not enter the separator chamber 14.
