  • Tapered roller bearings of this type are used in a variety of applications, whereby it is usually necessary to have a defined axial preload between the two conical surfaces. Roller bearings to ensure a stable radial and axial bearing is ensured. Setting the correct preload is often associated with great effort. It is important that neither too low nor too high an axial preload is provided to ensure optimum storage. A particular problem is the fact that the size of the bias depends on the current temperature of the bearing assembly.
  • the present invention is based on the invention to develop a generic bearing assembly so that the setting of an axial preload in a simpler manner is possible. It is particularly desirable that the bias automatically builds up in dependence on the operating temperature of the bearing assembly in the desired manner. This is particularly interesting in large storage applications, such as in bearings of the rotors of wind turbines.
  • the solution to this problem by the invention is characterized in that at room temperature between the end face of the section and the axial stop on the first or second machine part a gap measured in the direction of the axis is present, which is between 30 ⁇ and 250 ⁇ , wherein at an increased operating temperature of the bearing assembly of the given between the end face of the portion and the axial stop gap is reduced by the thermal expansion of the bearing assembly to zero.
  • the clamping sleeve preferably carries the two outer rings of the two tapered roller bearings.
  • the two tapered roller bearings can be positioned in X-arrangement.
  • the gap is preferably at 20 ° C between 30 ⁇ and 250 ⁇ , preferably between 50 ⁇ and 150 ⁇ , wherein it is reduced to zero at an operating temperature of more than 50 ° C.
  • the clamping sleeve may have a resilient portion at least in its region between the two cylindrical seats for the bearing rings.
  • the elastic section ensures that the desired heat-related expansions are not affected by areas of the clamping sleeve, which do not have to stretch due to heat.
  • the resilient portion of the clamping sleeve can be formed by reducing the wall thickness of the clamping sleeve. Alternatively or additionally it can be provided that the resilient portion of the clamping sleeve is formed by recesses which are introduced into the clamping sleeve. These recesses can be formed by the clamping sleeve radially passing through holes.
  • the clamping sleeve may further comprise friction-reducing means in a contact region between the clamping sleeve and the first or second machine part and / or between the clamping sleeve and a bearing ring.
  • These means may be formed by at least one annular groove which is incorporated into the clamping sleeve on a radially inner or radially outer cylindrical surface, wherein in the annular groove, a lubricant, in particular grease or graphite, is introduced.
  • the clamping sleeve is preferably made of a material having a high thermal expansion coefficient, in particular of aluminum, magnesium, copper or brass.
  • the clamping sleeve can be arranged between a rotor to be supported and the inner rings of the tapered roller bearings. Equally, it is also possible that the outer ring ge the tapered roller bearings are held by the clamping sleeve, wherein the clamping sleeve is then arranged in a housing part.
  • Fig. 2 shows the side view of a rotationally symmetrical clamping sleeve, which is part of the bearing assembly and

  • the two tapered roller bearings 2, 3 have in a known manner in each case an inner ring 4 and 5, an outer ring 6 and 7 and arranged between the rings tapered roller rows 8, 9.
  • the bearing assembly 1 supports a first machine part 10 in the form of a rotating shaft relative to a second machine part 11 in the form of a housing.
  • the axis of rotation of the shaft 10 is designated by a.
  • the clamping sleeve 14 has for this purpose a cylindrical seat 15, which is provided to receive the cylindrical seats 12 and 13 of the two outer rings 6, 7.
  • the bearing rings 4, 5 are fixed on the shaft 10 by an end portion 25.
  • the bearing outer ring 7 is seated radially indirectly in the housing 11; but it lies axially against an axial stop 16, which is formed by an end portion 26 which is fixed to the housing 11.
  • the other bearing outer ring 6 is also seated radially in the housing 11. But also axially it (in Fig. 1 left) not directly on the housing 11, but on an axial stop 17, which is formed by a radially reduced portion 18 of the clamping sleeve 14 , This section extends over a longitudinal extension in the direction of the axis a, before an end face 19 closes the clamping sleeve 14.
  • This end face 19 is provided to come into abutment with an axial stop 20 of the housing 11 during operation of the bearing arrangement.
  • the shaft 10 heats up, it expands in the axial direction a.
  • the axially expanding shaft 10 drives the two bearing outer rings 6, 7 away from each other, which axially expands the clamping sleeve 14. Accordingly, the gap s becomes smaller until it eventually becomes zero;
  • the thermal expansion of the shaft 10 transmits via the bearings 2, 3 on the clamping sleeve 14, so that the portion 18 presses with its end face 19 axially on the stopper 20, so that the two tapered roller bearings 2, 3 are braced in the axial direction ,
  • the clamping sleeve 14 is provided with a resilient section 21 in its middle region.
  • this section 21 is best shown in Figures 2 and 3. Accordingly, first of all, the wall thickness d of the clamping sleeve 14 is reduced in this area, which makes the center part of the clamping sleeve per se elastic, ie compliant. Then recesses 22 are introduced in the form of holes in the central region, which cause an additional weakening of the material and so give the central region of the clamping sleeve 14 a defined spring elasticity.
  • a plurality of bores 22 are arranged axially next to each other, furthermore a plurality of bores in the circumferential direction of the clamping sleeve 14 are arranged equidistantly.
  • means 24 are provided which ensure in defined contact areas 23 between clamping sleeve 14 and housing 11 that the temperature-induced and desired displacements of the components are not hindered.
  • These means are in the embodiment of annular grooves which are filled with a medium which increase the sliding properties, for. As graphite or grease. It may also be a sliding material, as it is used in slide bearing construction.
  • the tapered roller bearings 2, 3 are thus positioned in the exemplary embodiment in an X arrangement, the outer rings 6, 7 being carried by the clamping sleeve 14.
  • the gap s is in the range of 100 ⁇ . Accordingly, the bearing assembly is not biased at room temperature.
  • the bearing assembly and in particular the shaft 10 become warm, so that it expands axially. Accordingly, the gap shrinks to zero and the surfaces 19 and 20 press each other. As a result, the bearing assembly is axially biased.
  • the dimensions of the clamping sleeve and the material parameters, in particular the coefficient of thermal expansion are chosen so that in the expected heating during operation a himeichende axial length change takes place, which not only makes the gap s to zero, but also builds up the desired bias. It can be provided that the dimensions and materials are chosen so that at the expected temperature difference between the operating temperature and ambient temperature about 100 to 250 ⁇ change in length of the clamping sleeve 14 arise.
  • the clamping sleeve 14 thus has recesses (in the present case the annular grooves 24) filled with sliding material (eg graphite or lubricant, in particular lubricating grease). Furthermore, the clamping sleeve 14 as described has an area with less Wall thickness, which acts as a spring, that reduces the rigidity of the clamping sleeve 14 in the axial direction.
  • sliding material eg graphite or lubricant, in particular lubricating grease.
  • the recesses 22 are introduced in the form of holes in the clamping sleeve 14.
  • the spring action can be controlled specifically.
