Definitions
- Radial foil bearings are provided for the aerodynamic mounting of shafts, with a load-bearing gas/air cushion being formed between the shaft and the radial foil bearing.
- the functionality is similar to that of a hydrodynamic plain bearing, with the difference that the shaft is supported by the radial foil bearing via an air cushion and not by a liquid cushion of a hydrodynamic plain bearing. What both functional forms have in common is that only the rotary movement of the shaft leads to the formation of the supporting cushion.
- Foil bearings differ from conventional aerodynamic bearings by having a compliant, resilient structure between the rotating shaft and the stationary housing member. Because of this feature, they are less rigid than conventional air bearings, but they can adapt to geometrical changes in the air gap, e.g. due to misalignment of the bearing seats or different thermal expansion of the shaft and housing, thus enabling greater operational reliability in practice in many applications ability.
- the radial foil bearing usually has a cover foil that is in contact with the stationary shaft and a corrugated foil that is arranged radially between the cover foil and the outer ring of the bearing and can deflect elastically in the radial direction.
- the radial foil bearing has two foils in contact with one another and the foils carry the outer ring so that the radial foil bearing can be accommodated in a housing.
- the outer ring can also be formed in one piece from the housing into which the foils of the radial foil bearing are inserted.
- the shaft If the shaft is rotated relative to the radial foil bearing, the air present in the air gap defined by standstill is displaced. Above a certain shaft speed, an air cushion forms between the cover film and the shaft, on which the shaft can slide.
- the foil package with its corrugated foil and its radial spring effect ensures that fluctuations in air pressure or vibration rations of the shaft in the radial direction do not affect the bearing and thus keep the air cushion stable.
- EP 2942537 A1 shows a radial foil bearing with three corrugated foils and an almost circumferential cover foil, the corrugated foils each having a hook-shaped end hooked into its own slot in the outer ring and the cover foil being inserted into one of the slots with the ends lying against one another.
- EP 3387275 A1 shows a radial foil bearing with three packs of cover foil and corrugated foil, each pack being plugged into a slot in the outer ring at each end of the foil.
- the CN 209990776 U shows a radial film bearing in which both the corrugated film and the cover film are formed almost completely circumferentially, each having an angled end with which both films are inserted into a common slot. This connection is then secured by clamping with a screw.
- EP 2473749 A1 shows a radial foil bearing with precisely one cover foil and precisely one corrugated foil for forming the bearing in an outer ring.
- the solution according to the invention is characterized by a radial film bearing in which there is a first arc segment consisting of a first cover film, the first arc segment being fixed on a carrier film, with a second arc segment consisting of a second cover film on the carrier film , arranged, with the two arcuate segments being placed one after the other on this carrier film, so that when the carrier film is rolled up, a tubular carrier with the two arcuate segments is formed and forms the radial film bearing, with the carrier film being designed as a corrugated film and thus being a corrugated film-like carrier film and has an elasticity or flexibility via this waveform.
- the corrugated foil-like carrier foil is preferably formed from a thin ( ⁇ 0.5 mm) sheet metal strip made of stainless spring steel sheet metal, which can be bent into a circular shape by hand or using an auxiliary device.
- the corrugated film-like carrier film is initially present as a flat strip to which the sheet segments made of a cover film are attached.
- the arch segments are formed into an arch shape from a cover film.
- the arc segments are then placed one after the other on the corrugated film-like carrier film, with two successive arc segments being spaced apart from one another in such a way that after the corrugated film-like carrier film has been rolled up to form the tubular carrier, one end of an arc segment overlaps the end of the subsequent arc segment either to a small extent ß is overlapped, contiguous or slightly spaced apart.
- the corrugated film-like carrier film is wrapped around the arc segments, so that the corrugated film-like carrier film has wrapped and surrounds the arc segments.
- the assembly of abutting cover and corrugated foils occurs after the formation of the tubular support, the corrugated foil being a single foil wrapping a plurality of arcuate cover foils.
- the individual corrugated foil designed as a corrugated foil-like carrier foil encloses the cover foils almost completely, with the tubular carrier being formed almost completely closed in the circumferential direction.
- the arcuate segments are directly and/or indirectly fixed at one end to the corrugated film-like carrier film, for example welded.
- the corrugated foil-like carrier film has positioning means, for example in the form of a recess, which can be brought into contact or alignment with this end of the sheet segment.
- the positioning means is designed as a notch on the edge of the strip-shaped, corrugated film-like carrier film and is therefore easily accessible for a tool that aligns the arcuate segment with this positioning means.
- a radial foil bearing as an assembly of arcuate segments and corrugated foil-like carrier foil can be used directly in a bearing mounting hole, for example a compressor housing, or as a self-retaining unit of arcuate segments and corrugated foil-like carrier foil with a bearing outer ring sleeve is connected, which is then in the unit can be installed.
- the radial foil bearing according to the invention can preferably be used for oil-free and high-speed rotor bearings, for example in fuel cell compressors, e-boosters or turbochargers, with the design of the radial foil bearing according to the invention enabling the most cost-efficient large-scale production possible and also a possibility for modular construction to cover the different requirements is provided with regard to the implementation of the radial foil bearing in the unit assembly.
- a third arc segment is formed with a third cover film, with three arc segments now on the corrugated film-like Carrier film are arranged one after the other, so that when the corrugated film is rolled in like a carrier film, the tubular carrier with the three arcuate segments is formed and forms the radial film bearing.
- the use of three arc segments has the advantage that the shaft can be better centered during operation.
- the number of arc segments and their sequential arrangement on a corrugated foil-like carrier film can be scaled or multiplied, i.e. several arc segments or groups of arc segments can be provided, which are firmly placed consecutively on the carrier film so that when they are rolled up the carrier foil of the tubular carrier with the arc segments is formed and the radial foil bearing is formed.
- the tubular carrier has a peripheral (closed) shape, with the ends of the corrugated foil-like carrier film facing one another.
- the opposite ends of the corrugated film-like carrier film can
- the ends of the corrugated sheet-like carrier film may be firmly bonded together to form a closed ring-shaped carrier. If the closed ring-shaped carrier is present with firmly connected ends, it can either be inserted into an outer ring or directly into a housing bore. If the ends of the ring-shaped carrier are not firmly connected to one another, an assembly or assembly aid is required to insert the tubular carrier into an outer ring or directly into a housing bore.
- the peripheral length of the corrugated foil-like carrier foil corresponds to at least 240° of the inner circumference of the receiving bore for the tubular carrier, whereby the corrugated foil-like carrier foil nestles against the circular shape of the inner peripheral surface of the bearing seat bore/bearing outer ring sleeve after the tubular carrier has been inserted and is therefore designed to fit.
- one end of an arc segment faces the end of a subsequent arc segment.
- the opposing ends contact each other.
- the opposite ends are spaced apart. Two arc segments can also overlap.
- the film of an arc segment can overlap with the film of a subsequent arc segment after the tubular carrier has been formed in order to form the functionally required wedge gap towards the rotating shaft in order to form the supporting air cushion.
- a further development of the invention provides that the ring-shaped carrier is inserted into an outer ring to form the radial foil bearing.
- the outer ring can be a separate component which, together with the tubular carrier, forms the radial foil bearing, which is then inserted into a housing.
- the outer ring can be formed by the housing itself, as a result of which the tubular carrier can be used to form the radial foil bearing.
- the invention is such that at least the one degree of freedom in an axial direction of the tubular support placed in the outer ring is locked.
- both degrees of freedom in both axial directions of the tubular support placed in the outer ring are locked.
- An advantageous embodiment of the radial foil bearing according to the invention with an outer ring provides that a degree of freedom in the circumferential direction of the tubular carrier gers, which is placed in the outer ring, is locked.
- the tubular support, which is inserted into the outer ring can be welded to it, so that a relative rotation between the tubular support and the outer ring is prevented.
