Definitions

  • the present invention relates to a bearing housing which comprises at least two bearings arranged successively in a coaxial fashion, such as ball bearings or roller bearings, for supporting a shaft which is rotatably arranged m the respective bearings.
  • An object of the present invention is to provide a device which renders it possible to quickly change a bearing so as to minimise the operational disturbance.
  • This ob ect is achieved by a bearing housing of the above-mentioned type, the bearing housing being designed m such manner that a space forms between the bearings and the bearing housing, and that at least one clamping means is adapted to bridge the space between at least one optional bearing and the bearing housing, for optional activation of the bearing at issue.
  • One or more optional bearings can be fixed m the bearing housing with the aid of the clamping means and thus be activated. This means that merely these bearings are used to support the shaft, while the other bearings are allowed to be unloaded.
  • the invention can be used to activate only one of a plurality of bearings which are arranged m the bearing housing.
  • the clamping means can instead be arranged to fill the space between another bearing and the bearing housing, thereby activating this bearing. The worn-out bearing is then completely disengaged from the bearing housing.
  • a plurality of bearings can be clamp- ed by the clamping means and activated. If one of the bearings is damaged or worn out, the clamping means can be arranged to disengage this bearing from the bearing housing. After that the intact bearing supports the shaft
  • the clamping means is suitably adapted so as to make it easy to activate and deactivate different bearings. This means that a change of bearing does not significantly interfere with the process m which the shaft is included.
  • the damaged or worn-out bearing can then be replaced by a new bearing on a suitable occasion, preferably m connection with the next planned overhaul of the installation. In this way a better utilisation of machinery and processes is achieved, and shut-downs m addition to the planned ones can be minimised.
  • the bearing housing may consist of a bearing housing, which has a first part and a second part, which are adapted to clamp between them said bearings, the space being formed of a clearance between the outer bearing ring of the bearing and the bearing housing.
  • the clamping means bridges the space between the bearing housing and the outer bearing races of one or more bearings, said bearing races thus being fixed so that the bearings are activated.
  • the clamping means may consist of, for example, one or more spacers, preferably one or more shims.
  • One or more spacers can be arranged m the space between an optional bearing and the bearing housing so that this bearing is held clamped and consequently supports the shaft.
  • Another bearing, with which no spacer has been arranged, is not engaged with the bearing hous- mg and thus is unloaded.
  • one part of the bearing housing can be removed and the shaft be slightly displaced to allow removal of the spacers. Subsequently one or more spacers are arranged adjacent to the other, so far unloaded bearing, and the parts of the bearing housing are reassembled. The other bearing is then clamped and activated whereas the damaged or worn-out bearing is now disengaged from the bearing housing and thus is unloaded and does not support the shaft.
  • a change of which bearing or bearings are activated thus requires but a slight displacement of the shaft which therefore need not be disconnected from the rest of the installation. This means that the change will be very quick, and the interruption thus affects, for example, a manufacturing process to a very small extent.
  • the first part of the bearing housing can be mount - able m two positions and be designed so that, m each position, it is engaged with one of the bearings and dis- engaged from another bearing.
  • clamping means need only be arranged between the activated bearing and the second part of the bearing housing.
  • the change is effected as described above, except that the first part of the bear- ing housing is turned half a revolution before being mounted once more, so that after being mounted once more, it is engaged with the bearing unloaded so far. Seals can be arranged between the bearings to prevent chips from an activated bearing from damaging a neighbouring bearing.
  • the bearings can be spherical, m which case a sup- porting element can be arranged to fix the free bearing ring of an unloaded bearing.
  • the bearings are designed m such manner that a space forms between the bearings and the shaft, and that at least one clamping means is adapted to bridge the space between at least one optional bearing and the shaft, for optional activation of the bearing at issue.
  • the bearing housing can then be a bearing housing having a first part and a second part, which are adapt - ed to clamp between them said bearings, the space being formed of a clearance between the inner bearing ring of the bearing and the shaft .
  • Fig. 1 is a cross-section of a bearing housing according to an embodiment of the invention
  • Fig. 2 is a cross-section along line II-II m Fig. 1,
  • Fig. 3 is a cross-section of a bearing housing according to a second embodiment of the invention
  • Fig. 4 is a cross-section along line IV-IV m Fig. 3
  • Fig. 5 is a cross-section of a bearing housing according to a third embodiment of the invention.
  • the bearing housing shown m Figs 1-2 consists of a bearing housing having a first part, m the shown exam- pie a cap 2, and a second part, m the shown example a base 3. These parts 2, 3 are fixedly secured to each other with the aid of fixing means 4, such as bolts 5, screws or clamps.
  • fixing means 4 such as bolts 5, screws or clamps.
  • two bearings 7a, 7b for example ball bearings, are arranged in the space 6 forming between the cap 2 and the base 3.
  • the bearings 7a, 7b are arranged successively m a coaxial fashion, and a shaft 8 is rotatably arranged m the respective bearings 7a, 7b.
  • the cap 2 is designed to extend further down above the one bearing 7a and is made to engage the outer bearing ring 12 of the bearing 7a.
  • the base 3 is designed so that a space 9a, 9b, forms under each bearing 7a, 7b.
  • a spacer such as a shim 10, is arranged m the space 9a between the bearing 7a and the base 3.
  • each bearing 7a, 7b On both sides of each bearing 7a, 7b, seals, such as sealing rings of packings 11, are arranged, which are adapted to protect a bearing from chips from another, damaged bearing. Since only one bearing 7a is fixed between the cap 2 and the base 3 of the bearing housing 1, it is only this bearing 7a which is activated and supports the shaft 8 when rotating. The bearing 7b can be rotated by the shaft 8, but does not support the shaft 8 since it has no con- tact at all with the bearing housing 1.
  • the cap 2 is released from the base 3.
  • the shim 10 is removed from its position under the bearing 7a, normally by being turned half a revolution m the direction of rotation of the bearing 7a until it is located on top of the bearing 7a and can be removed. Subsequently the shim 10, or another shim if the old one has been worn out or damaged, is placed under the bearing 7b.
  • the shaft 8 need only be raised about a tenth of a millimetre to enable such displacement of the shim 10.
  • the cap 2 of the bearing housing 1 is fixed once more after being turned half a revolution.
  • m Figs 3-4 A different embodiment is illustrated m Figs 3-4 m which the parts identical with those m Figs 1-2 have the same reference numerals as m Figs 1-2.
  • the bearing housing 101 m Figs 3-4 has a cap 102 which is designed m the same way above both bearings 7a, 7b.
  • spacers such as shims 10, are placed m the spaces 9a, 109a both below and above the bearing 7a.
  • bearings 7a, 7b It is also possible to utilise more than two bearings 7a, 7b. Then a plurality of changes of bearing could be carried out successively until all bearings m the bearing housing have been worn out or damaged.
  • bearings are activated and deactivated, for example, m pairs or three at a time.
  • clamping means instead of spacers, other forms of clamping means could be employed.
  • contact faces round the bearings can be arranged to be movable radially towards the bearings, or the bearing rings of the bearings can be fixable by clamping action m the axial direction.
  • the contact faces or the means providing clamping action could also be operated from the outside of the bearing housing by means of straining screws or some other control means. In this way, it would not be necessary to open the bearing housing to accomplish activation and deactivation of bearings.
  • the bearings are fixedly arranged between the first part 202 and the second part 203 of the bearing housing 201. Instead a distance forms between the shaft 8 and the inner bearing ring 13 of the bearing 7a. A bearing is then activated by this distance 14 being bridged, for instance by wedging m a spacer (not shown) or by fixing the inner bearing ring 13 of the bearing m some other manner.
