Definitions
- the present invention relates to a resilient (slide) bearing device, which is used in connection with support of large, heavy and rotating elements. This may involve, for example, support of a turret in a vessel, support of a crane or bridge, etc. where external influences expose the bearings to great dynamic stresses.
- a bearing is generally defined as a device for positioning one element relative to another in such a manner that relative movement between the elements is possible.
- the elements have respective bearing surfaces which are in contact with each other.
- the bearing surfaces will normally be covered by a lubricant which is used in order to facilitate the relative movement between the elements, reduce the wear on the bearing surfaces, reduce corrosion, etc.
- Bearings and bearing surfaces are chosen by determining the mechanical movement and function they have to fulfil, their working life and reliability as well as the existing conditions such as temperatures, any pollution, corrosion risk, vibrations, cyclical loads etc.
- slide bearings where the bearing surfaces of the bearing elements are usually divided by a lubricant which forms a thin film.
- the lubricant may be various types of oil and/or fat.
- slide bearings covers a wide range of bearing devices in which the relative movement of the bearing elements involves a sliding movement of one bearing surface over the other bearing surface.
- Different materials are used for slide bearings, and particularly in the bearing surfaces, including metals such as various cast iron alloys, steel alloys, aluminium alloys, copper alloys and many other metals, engineering plastics of different types, including both thermoplastics and thermosetting plastics, various glass or ceramic materials, wood and many other materials.
- Bearings are generally employed in order to absorb loads and/or support one or more elements.
- the element may be rotating, for example a rotating shaft, or it may be fixed, for example a bridge or the like.
- a bearing may also be designed to be able to absorb both axial and radial forces.
- the bearing type must be chosen on the basis of what it has to be used for.
- slide bearings may be employed.
- a slide bearing is composed of a bearing surface which may be made of a metal, an alloy or a synthetic material.
- the bearing must be designed so as to be capable of withstanding the highest stresses, even though these stresses are of short duration. The result of this, however, is that the bearing does not function optimally, since on one hand it must be able to tolerate peak loads (which occur for short periods at a time), and for the rest of the time must be able to absorb the normal loads.
- FPSO Floating Production, Storage and Offloading Vessel
- a vessel of this type can be exposed to substantial wind, current and wave influences, which can result in dynamic deformations in the hull and thereby also in bearings and bearing surfaces.
- An object of the present invention will therefore be to provide a bearing which can absorb both normal and large, fluctuating loads, where at the same time wear on the bearing surfaces is reduced over time. It is a further object to provide a bearing which is easy and cheap to produce as well as a bearing on which it is easy to carry out service/maintenance. It is also desirable to provide a bearing in which an attempt is made to avoid or at least reduce the drawbacks of existing bearings.
- a bearing according to the invention is particularly intended for use in connection with support of a turret on board a vessel, but it may also be employed in connection with support of other large, heavy and rotating elements, where a resilient slide bearing has to be capable of absorbing the varying loads which will exist over the bearing during the rotating motion.
- a plurality of bearings according to the invention may be arranged in a circle in order to support the turret in the rotating motion.
- the bearing according to the invention is a spring slide bearing. It comprises a housing and in relation thereto a relatively movable abutment surface connected to a bearing insert.
- the bearing insert comprises two or more elastic elements with different modulus of elasticity mounted behind one another viewed in the length of a centre axis of the bearing housing and devices for gradual absorption of loads to which the bearing is exposed.
- centre axis for the bearing housing should be understood here to mean an axis extending from the abutment surface into the housing, having an orientation substantially perpendicular to the abutment surface.
- the elastic elements may be mounted in the bearing housing with at least one distance piece between the elastic elements, viewed in the direction of the centre axis.
- the bearing comprises devices which permit the distance piece to have a restricted movement relative to the housing, thereby achieving the gradual absorption of the loads.
- the inside of the bearing housing may be provided with through-going openings, or internal cut-outs or the like which permit the distance piece to move relative to the housing internally in the opening or the cut-out and where at least an edge of the opening or the cut-out will act as a physical barrier to the distance piece's or pieces' movement, thereby stopping further compression of the bearing or of the bearing insert's elastic elements.
- these openings and/or cut-outs will also permit the distance piece to be angled relative to the centre axis for the housing.
- the softest elastic element on account of the load to which it is exposed, will firstly be compressed a permitted amount, but denied further compression as a restricting body, on account of the same load, is brought into engagement with a distance piece, which by means of this cooperation between the distance piece and the restricting element, stops further compression of the elastic element.
- the restricting body will cooperate with the distance piece, transferring the load forces to a harder elastic element without further loading of the softer elastic element.
- Such a construction can be employed for two or more stages of elastic elements, thereby achieving a gradual absorption of the load forces, where the hardest elastic element absorbs the greatest forces without unnecessary loading on any elastic elements which are softer than this.
- the restricting body may be a sleeve loosely arranged between the abutment surface and a distance piece or between two distance pieces, or alternatively it may be provided as a part of the element forming the abutment surface, or as a further alternative as a part of the distance piece or a combination thereof.
- the restricting body may furthermore be a whole annular sleeve, or rods or another rigid structure which stops further compression of an elastic element.
- the bearing according to the invention may further comprise a force transfer element mounted between or as a part of the abutment surface of the bearing and the elastic elements.
- the abutment surface is composed of a surface of the force transfer element.
- This force transfer element may comprise several separate elements assembled to form a unit and may be designed so as to absorb any angular deviation to which the bearing is exposed. This may be achieved, for example, by providing between two relatively movable elements of the force transfer element a partly spherical joining surface.
- the force transfer element moreover, may also be arranged to permit lubrication of the bearing surface by lubricating devices mounted in the force transfer element or to release the entire bearing from the support surface.
- the elastic elements may advantageously be elastomers, springs, compressible fluids or a combination thereof.
- the elastic elements may advantageously be placed in layers across the housing's centre axis, divided by at least one distance piece, where the distance piece may be a disc of a circular, square or rectangular shape, and where the disc may furthermore be solid, hollow/annular, latticed, etc.
- the disc may moreover be provided with partly spherical edges in order to permit tilting of the disc. These spherical edges may cooperate with cut-outs or openings in the housing to permit tilting of the distance piece.
- One cut-out may be provided per distance piece in the housing with identical or different shapes.
- the bearing according to the invention will furthermore be able to be used both as an axial bearing and a radial bearing, or a combination thereof.
- the movement between the elements provided by the bearing according to the invention can be facilitated by means of the bearing's lubricating devices, where these devices may also be employed for hydrostatic release of the bearing.
- the lubricant will also be able to reduce the wear on the bearing surfaces.
- Another advantage of the bearing in the present invention is the simple and uncomplicated way of carrying out maintenance/service, wherein the bearing is attached from its top by means of suitable fastening devices to the element it is to support, where top should be understood here to refer to the side of the housing facing away from the bearing surface; during maintenance or service the fastening devices will be easily removed, whereupon the bearing housing can be removed.
- the bearing insert will thereby be uncovered, and, for example, the elastic element which is worn can be replaced; alternatively it may also be envisaged that "the degree of hardness" of one or more of the elastic elements has to be replaced, which means that only this or these elastic elements are replaced, while the remaining elements in the bearing continue to be used.
- Figure 1 is an exploded view of a bearing according to a first embodiment of the invention.
- Figure 2 is an exploded view of a bearing according to a second embodiment of the invention.
- Figure 3 is an exploded view of a bearing according to a third embodiment of the invention.
- Figure 4 shows partial side and perspective views of the bearing mounted in a turret on board a vessel.
- a resilient bearing 1 comprises a housing 2 with an axial centre axis 11 , wherein a bearing insert 3 is mounted in the housing 2.
- the bearing insert 3 comprises devices 4, 5, 6, 7 for gradual absorption of the loads to which the bearing 1 is exposed from an abutment surface 12.
- the housing 2 covers the bearing insert 3 on all sides except the side comprising the abutment surface 12.
- the housing 2 may be closed in its surface, with the result that the bearing insert 3 is completely covered from the environment or more open, with the result that it forms a support structure round the bearing insert 3 but does not cover it.
- the housing 2 is secured to an element, a turret 17 (see also fig.
- the bearing insert 3 comprises two elastic elements 4, which are located in layers across the housing's 2 centre axis 11. These elastic elements 4 may be made of any kind of suitable material, but are preferably elastomer(s), spring(s), compressible fluids, etc., or also a combination thereof.
- the special design of these surfaces permits the bearing surface 12, which is a part of the force transfer element 7, to be subjected to tilt or angular deviation relative to the centre axis 11 for the bearing without the elastic elements 4 being subjected to corresponding angular deviation.
- the force transfer element 7 is further provided with a supply duct 13 for lubrication or hydrostatic release of the bearing surface 12.
- the restricting body 6 is in the form of a sleeve 61 with a bottom part 62, these together forming an internal cavity 63 in the restricting body 6, wherein one of the elastic elements 4 is mounted.
- a lubricating or release device 10 comprising a supply opening 64 provided at an outside of the restricting body 6, leading to a supply duct 65; this device cooperates with the supply duct 13 in the force transfer element 7, thereby enabling lubricant to be applied to the bearing surface 12, or the device 10 also to be used for hydrostatic release of the entire bearing 1.
- the two layers of elastic elements 4 are separated by a distance piece 5, which together with the restricting body 6 is intended to restrict the compression of the softest element 4 in a manner which will be explained in greater detail below.
- the bearing housing 2 On its inside, in the area round the distance piece's 5 position, the bearing housing 2 is provided with a cut-out 21.
- the alternative to a cut-out will be to provide the housing 2 with through-going holes/openings.
- the object of this design is to stop further compression of the bearing insert 3 when it is subjected to what has been determined to be the maximum load for the bearing. If the bearing 1 is exposed to large loads, the softest elastic element 4 (in the figure this corresponds to the elastic element 4 mounted closest to the bearing surface 12) will first begin to be compressed.
- the element is permitted to be compressed until the restricting body 6 is brought into contact with the distance piece 5, and the hardest elastic element 4, which in the figure abuts against the distance piece's 5 upper side, will not be compressed by this load.
- the softest elastic element 4 has been compressed to such an extent that the restricting body 6 is brought into contact with the distance piece 5, no further compression of the softest elastic element will occur. If the bearing is not exposed to greater loads, only the softest element 4 will be functional, and this will be the case for the greater part of the bearing's 1 life. However, when the bearing 1 is exposed to additional loads, i.e. greater than those mentioned above, the hardest elastic element 4 will begin its compression.
- the distance piece 5 may be provided with partly spherical lateral edges, which may permit a certain amount of tilting of the member 5 relative to the housing 2.
- the elastic element's 4 spring properties (modulus of elasticity) is determined on the basis of the loads to which the structure may be exposed in addition to any other parameters which may influence these properties, where this results in the softest elastic element 4 having a spring characteristic which will be capable of absorbing the normal loads for most of the time (typically 85-95% of the time), while the hardest elastic element will be selected on the basis of the extreme loads (for example in the event of a storm) to which the bearing is exposed, and where this results in the hardest elastic element 4 being functional only for infrequent and short periods at a time.
- the lubricant may be any kind of suitable material, from fluids such as water, oil, soap, fat and air to solids such as graphite, molybdenum, polytetrafluorethylene (PTFE), etc.
- the force transfer element's 7 abutment surface 12 is provided with a groove 71 leading out from the supply duct 13, thereby facilitating the spreading of the lubricant over the abutment surface's 12 contact area. It may also be possible to attach (not shown) the force transfer element 7 to the restricting body 6 by means of spring devices, which permit tilt to be absorbed.
- the bearing 1 is provided with through-going openings 15 for attachment of the bearing 1 to one of the elements, the turret 17 or vessel 16 respectively, where these may be bolts, etc.
- a second embodiment of the bearing 1 according to the invention is illustrated, where this also comprises a housing 2, in which housing a bearing insert 3 is mounted.
- two elastic elements 4 are arranged in layers across the housing's 2 centre axis 11.
- the distance piece 5 will be provided with walls 52 extending in the bearing's 1 axial direction towards the abutment surface 12, where these walls 52 collaborate with collaborating walls 72 (see also figure 3) in the force transfer element 7 extending in the axial direction towards the distance piece 5, thus enabling the restricting body 6 to be omitted.
- the force transfer element 7 in this embodiment is flat, forming a surface 73 (see also figure 3) for abutment against an elastic element 4 which together with the walls 72 forms a cavity for secure placement of the elastic element 4, and in addition that the surface of the force transfer element facing radially outwards as well as the outer walls 74 (see also figure 3) in the element are partly spherical in shape.
- This partly spherical construction of the outer walls 74 permits angling of the abutment surface 12 relative to the centre axis 11 to be directly absorbed by the softest elastic element 4.
- the figure further shows that a sleeve 9, provided between the housing 2 and the distance piece 5/the force transfer element 7 will be capable of absorbing radial forces to which the bearing 1 is exposed, the sleeve 9 being designed on its inside complementarily to the partly spherical walls in the force transfer element 7.
- FIG 3 Yet another embodiment of the bearing according to the invention is illustrated in figure 3, where the intermediate and freely rotating sleeve 9 is removed.
- the force transfer element 7 is instead provided with such a large diameter that it abuts against an inner wall 23 of the housing 2.
- the force transfer element's 7 lateral surfaces are provided as partly spherical surfaces 74, where this will permit the element 7 to be allowed an angular deviation or tilt, which will be able to be absorbed by the elastic element 4 located within.
- the force transfer element 7 is further provided with walls 72 extending in the bearing's 1 axial direction.
- the distance piece's 5 lateral edges will be provided with partly spherical surfaces and with walls 52 extending in the bearing's 1 axial direction towards the force transfer element 7.
- the walls 52, 72 which are brought into contact with each other during compression of, for example the softest elastic element 4, and which in this embodiment are composed of the distance piece 5 and the force transfer element 7, and which form the restricting body 6, may be provided as a part of the respective piece/element, or they may be provided as free-standing elements which are placed between them.
- the bearing 1 according to the invention is illustrated employed on board a vessel 16 (only a few portions are shown), where a turret 17 (only partly shown) has to be mounted rotatably in the vessel 16.
- the vessel's hull 18 is provided with a through-going opening 19 for receiving the turret 17, where slide bearings 1 are arranged in the contact surfaces between them 16, 17.
- an annular path with vertical walls which interact with corresponding vertical walls on the turret.
- a number of radial bearings 1 are mounted on the hull's vertical walls, while inside the turret's vertical walls are mounted a number of bearings 1 in order to absorb axial loads.
- the bearings 1 are illustrated here in a circular form, arranged so that together they form an annulus, but they may assume any other form whatever.
- a bearing may, for example, be designed in three or more layers with elastic elements in the direction of the bearing's centre axis.
