Definitions
- the present invention relates to a hydrodynamic or hydrostatic plain bearing for the rotatable mounting of a shaft, in particular in a wind turbine, with at least one first sliding element with a first sliding surface, which is arranged on a connecting structure so as to be radially and/or axially displaceable.
- the invention further relates to a method for adjusting a bearing clearance on a hydrodynamic or hydrostatic plain bearing and to a wind turbine.
- plain bearings in the area of transmission gears for wind turbines is also generally known, as shown in EP 1 184 567 A2.
- Another area of application for plain bearings in wind turbines can also be a tower bearing, as is also known from DE 100 43 936 A1.
- plain bearings for the bearing of the rotor blades of a wind turbine as is clear from DE 102005 051 912 A1, for example.
- hydrostatic plain bearings For this purpose, the volume flow in hydrostatic plain bearings is usually provided by an electric pump (e.g. gear pump).
- a hydrostatic plain bearing thus has an active lubricant circuit, which is maintained by an external pump and which is guided through the bearing gap between the elements moving relative to each other.
- a thin hydrostatic bearing film builds up in the bearing gap, which reduces the friction between elements moving relative to each other.
- hydrodynamic plain bearings in which the lubricating film is only generated by the movement of the plain bearing. This is usually achieved by a wedge-like lubricating gap, so that the lubricant carried from the surface of the moving bearing part into the constriction is transmitted via the interposed lubricant film.
- segmented, hydrostatic or hydrodynamic plain bearings represent a technically interesting solution for the rotor bearings (main bearings) of wind turbines in the range of 10 MW and more. Due to the size of the system, rolling bearings of a size that is challenging both in terms of production and logistics would be required. In addition, segmented plain bearings can potentially be replaced or repaired on the tower in the event of damage. For the plain bearing to function, it is essential that the individual sliding elements are precisely aligned and that a uniform, very small clearance is set between the individual segments and the rotor shaft and that they are attached easily and securely once the clearance has been adjusted.
- a hydrodynamic or hydrostatic plain bearing for the rotatable mounting of a shaft, in particular in a wind turbine, with at least one first sliding element with a first sliding surface, which is arranged radially and/or axially displaceably on a connecting structure, wherein a first ramp section is provided on the at least first sliding element and a corresponding second ramp section is designed such that an axial offset of the sliding element relative to the connection structure causes a radial offset of the sliding element and/or vice versa, so that the bearing play of the sliding element relative to the shaft is adjustable.
- clamping element provides an improved possibility for the exact positioning of the sliding element on an inclined plane and a fail-safe fixation of this sliding element during operation of the plain bearing.
- the plain bearing can be designed as a radial bearing or axial bearing.
- connection structure can be designed as a bearing ring, for example.
- the bearing ring is particularly preferably designed as a separate component, so that the plain bearing can also be pre-assembled in a modular manner and can be used at a location equipped with the corresponding sliding elements. It would also be possible in principle for a bearing ring to be designed in segments. It is also conceivable for the connection structure to be formed from part of a housing. A connection structure can also be formed from part of a structure of a wind turbine. This can have the advantage that only structurally comparatively small elements of the plain bearing have to be transported into a nacelle of a wind turbine, which can bring both logistical and assembly-related advantages.
- the sliding element in one piece, in particular monolithically. This allows the sliding element to be designed to be self-retaining in a particularly advantageous manner.
- the sliding element can also be formed from several separate components. In the case of these separate components, a connection between them can then be provided by means of screws or welding.
- the sliding element can therefore also be designed in several parts.
- the sliding surface is formed on a structurally separate part of the sliding element and is connected, for example, to a base body of the sliding element.
- the sliding bearing can preferably have a plurality of sliding elements, each with a sliding surface.
- the sliding elements are preferably designed to be essentially identical. The high degree of uniformity allows the manufacturing costs to be further reduced.
- the at least first sliding element can be displaced relative to the connection structure by means of a first adjusting screw.
- the adjusting screw preferably engages directly in a bore in the sliding element with a corresponding internal thread.
- a second displaceable clamping element is arranged in the at least one guide groove next to the first displaceable clamping element, wherein the first clamping element is positioned in a first channel and the second clamping element in a second channel of the guide groove and the first clamping element is coupled to the first free end of the T-like section and the second clamping element is coupled to the second free end of the T-like section.
- first clamping element and the second clamping element can be designed as one piece, in particular monolithically.
- the clamping elements can be connected to one another in a U-like or clamp-like manner.
- the first clamping element can be displaced relative to the connection structure by means of a second adjusting screw and/or the second clamping element can be displaced relative to the connection structure by means of a third adjusting screw. This makes it possible in particular to achieve a very precise and assembly-friendly fixation of a sliding element by means of the clamping elements.
- the invention can also be further developed in such a way that a cover plate is fixed to the connection structure, through which the first adjusting screw and/or the second adjusting screw and/or the third adjusting screw pass.
- the removable cover plate enables in particular a simplified assembly of the sliding element and the clamping elements, since these can first be pushed or inserted into the connection structure from one axial side and can then be fixed via the cover plate that is then placed on the connection structure.
- it can be used to axially fix the adjusting screws.
- the cover plate can preferably be connected to the connection structure via a screw connection.
- the adjusting screws can preferably have a screw head.
- an adjusting screw can be headless, i.e. to consist only of a threaded rod.
- the first adjusting screw is locked to the cover plate by means of an adjusting nut. This allows the bearing clearance setting to be secured first before the sliding element is finally fixed by the clamping element(s), which can further improve adjustability and assembly.
- connection structure has a hydraulic channel which can be supplied with a hydraulic fluid and which is inserted into the ramp section of the connection structure
- the advantage that can be achieved in this way is that the sliding element can be moved along the ramp section more easily by introducing lubricant via the hydraulic channel.
- the lubricant is particularly preferably also pressurized, which can further simplify the sliding element's ability to move.
- the object of the invention is further achieved by a method for adjusting a bearing clearance on a hydrodynamic or hydrostatic plain bearing, comprising the following steps:
- connection structure for receiving the at least first sliding element, with a second ramp section which interacts with the first ramp section such that an axial offset of the sliding element relative to the connection structure causes a radial offset of the sliding element and vice versa, so that the bearing play of the sliding element relative to the shaft can be adjusted
- connection structure has at least one guide groove into which the at least first sliding element can be inserted, wherein the guide groove is designed such that the two free ends of the T-like section each engage behind a guide section, so that the at least first sliding element is held captively in the guide groove in the radial direction
- the object of the invention can also be achieved by a wind turbine comprising a hydrodynamic or hydrostatic plain bearing according to one of claims 1-9 for the rotatable mounting of a shaft.
- Figure 1 shows a plain bearing in a perspective view
- Figure 3 is a first axial sectional view through a sliding element arranged in the bearing
- Figure 4 shows a second axial sectional view through a sliding element arranged in the bearing
- Figure 5 is a tangential sectional view through the sliding element arranged in a bearing
- Figure 6 is a cross-sectional view through a first embodiment of a sliding element arranged in the bearing
- Figure 7 is a cross-sectional view through a second embodiment of a sliding element arranged in the bearing
- Figure 8 shows a wind turbine with a plain bearing in a schematic representation.
- Figure 1 shows a hydrodynamic or hydrostatic plain bearing 1 for the rotatable mounting of a shaft 3, in particular for a wind turbine 2, as is also shown by way of example in Figure 8.
- a wind turbine 2 usually has an electric machine 41 driven by a shaft 3 via a gear arrangement 40.
- the shaft 3 can be rotatably mounted on a plain bearing 1, as will be explained in more detail below.
- the plain bearing 1 has a plurality of essentially identical sliding elements 4, which are arranged equidistantly distributed around the circumference on the connection structure 6 designed as a bearing ring. In order to avoid repetition, the functionality is explained below using the example of just one sliding element 4. It is understood that a plurality of the sliding elements 4 in the plain bearing 1, preferably all sliding elements 4, are constructed and function as explained below using a sliding element 4.
- Figure 2 shows a first sliding element 4 with a first sliding surface 5, which is arranged on a bearing ring 6 so that it can be displaced radially and axially.
- a first ramp section 7 is formed on the sliding element 4 and a corresponding second ramp section 8 is formed on the bearing ring 6 in such a way that an axial offset of the sliding element 4 relative to the bearing ring 6 causes a radial offset of the sliding element 4 and vice versa, so that the bearing play of the sliding element 4 relative to the shaft 3 is adjustable.
- the slope of the axially extending ramp sections 7, 8 runs in the radial direction.
- the sliding element 4 is held clamped relative to the bearing ring 6 by means of at least one clamping element 9 which can be displaced relative to the bearing ring 6, which can be clearly understood from the combination of Figures 4-7 and is explained in more detail below.
- the bearing ring 6 has a guide groove 10 for each sliding element 4, into which the sliding element 4 is inserted.
- the sliding element 4 has a T-shaped section 11 which extends in the radial direction out of a base body 12 of the sliding element 4 and into the bearing ring 6 and is pronounced of a double-T beam in cross-section.
- the guide groove 10 is designed in such a way that the two free ends 13a, 13b of the T-shaped section 11 each engage behind a guide section 14, so that at least the first sliding element 4 is held captively in the guide groove 10 in the radial direction and a sliding element cannot fall out of the bearing ring 6 even in an overhead situation.
- the sliding element 4 can be displaced relative to the bearing ring 6 by means of a first adjusting screw 15.
- the first adjusting screw 15 engages in a corresponding bore 35 of the sliding element 4 and, by rotating the screw, causes an axial offset along the ramp sections 7, 8, so that the sliding element 4 is also radially displaced in accordance with the slope of the ramp sections 7, 8.
- the clamping elements 9, 17 each have a ramp-like section 42, which is formed on a corresponding ramp-like section 43 on the axially extending side surfaces of the free ends 13 of the T-like section 11, which can be particularly clearly understood from Figure 5.
- the slope of the axially extending ramp-like sections 42, 43 runs in the circumferential direction. This has the effect that when the adjusting screws 16, 20 are tightened, the sliding element 4 is also pulled radially outwards against the bottom of the guide groove 10 and clamped, which contributes to a particularly firm fit of the sliding element 4 in the guide groove 10 and enables a particularly good and secure radial force transmission between the sliding element 4 and the bearing ring 6, without local stress peaks occurring at the bottom of the guide groove 10.
- the clamping elements 9,17 are then supported in the radial direction on the guide sections 14a, 14b in the guide groove 10.
- a method for adjusting the bearing clearance on the hydrodynamic or hydrostatic plain bearing 1 can now comprise the following steps:
- At least one first sliding element 4 is provided with a first sliding surface 5 and a first ramp section 7 as well as a T- like section 11 with two free ends 13a, 13b, which extends out of a base body 12 of the sliding element 4.
- At least one clamping element 9 is also provided, which can be displaced relative to the bearing ring 6 and inserted into the guide groove 10.
- the sliding element 4 is inserted into the guide groove 10 of the bearing ring 6 and at least one clamping element 9 is inserted into the guide groove 10 and the guide groove 10 is then closed by the cover plate 21.
- the bearing clearance is then adjusted by offsetting at least the first sliding element 4 in the guide groove 10.
- the adjusting screw 15 can be turned for this purpose.
- hydraulic fluid 24 can also be fed under pressure through the hydraulic channel 23 in order to facilitate the adjustment process by appropriately lubricating the ramp sections 7, 8.
- Displacement of the clamping element 9 in the guide groove 10 relative to the bearing ring 6 is finally fixed so that at least the first sliding element 4 is held in a clamped position relative to the bearing ring 6.
- the clamping element 9 is tightened by means of an adjusting screw 16.
- This adjusting screw 16 is of course still loose when the bearing play is adjusted using the adjusting screw 15 so that the bearing play adjustment is not hindered by the clamping element 9.
