Definitions

  • the present invention relates to a bearing assembly for shut-off and control dampers in flue ducts, which assembly includes bearing devices and sealing devices and in which the bearing devices are arranged in connection with the frame structures of the dampers in order to shut off and control the said dampers, and in which shaft members arranged in the damper are fitted to the bearing devices.
  • a bearing assembly is known, for example, from EP 0 023 953 A .
  • shut-off and control dampers which hereinafter are referred to by the shorter general term of dampers, are generally arranged on shafts in their frame structures. Bearings are arranged on one side of the frame structure and are followed by the operating linkages and their adaptations, which are connected to operating devices that move them. 'On side opposite to this operating side, bearing devices, which are intended to ensure frictionless opening and closing operations, are arranged in the frame structure.
  • the temperatures of the gases flowing in the duct are usually hundreds of degrees, for example, 200 - 400 °C.
  • the flue gases comprise gases containing substances such as sulphur and soot particles. Such conditions place great demands on the bearings of the dampers, and particularly on their lubrication and the lubricating substances.
  • bearing assemblies in which the shaft seals of the bearings are arranged in the frame structure (for example, EP-754 916 , EP-937 872 ).
  • the shaft seal is immediately followed by, for example, a journal or ball bearing, which is exposed to the flue gases travelling through the damper, and especially to the solids particles in them.
  • the known bearing assemblies used in dampers are either permanently lubricated bearings, or bearings requiring further lubrication at intervals, freedom from maintenance being, however the main criterion of these assemblies. Permanently lubricated bearings are lubricated, for example, during assembly at the factory.
  • Permanent lubrication is often the only alternative for the lubrication of bearings in certain positions, because grease nipples, which permit later lubrication, cannot be arranged in connection with their bearing shells; instead, they must be arranged to be as tightly sealed as possible, to prevent heated lubricant from flowing or evaporating out of the bearings. It is particularly precisely assemblies with ball bearings that generally require maintenance.
  • soot particles, impurities, and similar that flow with the flue gases cause not only heat, but also the hardening of lubricants, thus substantially reducing the effective lubrication of the bearings. This essentially weakens the movability of the dampers and in the worst cases causes the damper to jam.
  • the hardening of the lubricant can also potentially block the greasing access, such as a grease nipple.
  • the lubricants that can be used must be selected according to the process.
  • the present invention is intended to create a new type of more operationally reliable and integrated bearing assembly for shut-off and control dampers in flue ducts.
  • the features of the bearing assembly according to the invention are stated in Claim 1.
  • the integrated bearing assembly according to the invention provides substantially improved functionality, by creating a proper seal between the flue gases travelling through the damper and the lubricant lubricating the bearings.
  • the bearing assembly also reduces the shaft load arising from the pressure of the flue gases. Further, essentially maintenance-free bearings become possible for dampers while the small size of the bearing assembly makes it significantly easier to apply to cramped plant environments.
  • Figure 1 shows an example of a preferred application of the bearing assembly according to the invention.
  • the damper construction shown here is intended, for example, for shutting off and controlling the flow of gases in the flue ducts of power plants.
  • the damper totality comprises a frame structure 11, to which three dampers 10 are attached by shafts 26.
  • Through-holes for the shafts 26 are arranged in the operating and maintenance side 27.1, 27.2 of the frame structure 11.
  • the shaft 26 of the damper 10 is mounted in bearing's protruding tube 25 and the end of the shaft 26 is fitted to the damper's 10 operating linkage 12, through which the dampers 10 are closed and controlled, for example, by a single operating device (not shown).
  • a bearing assembly 13 according to the invention is fitted to the operating end 27.1 of each shaft 26.
  • Figures 2 and 3 show a first bearing assembly 13 according to the invention.
  • the diameter of a hole limited by the collar 15.1 is arranged so that it forms a tight fit essentially with the shaft 26 of the damper 10 ( Figure 1 ).
  • the internal diameter of the first sleeve member 15.1 is, except for the area of the internal collar 15.1', adapted to the thicknesses of plaited seal rings 16.1, 16.2 which are fitted to the internal circumference 15.1* of the sleeve member 15.1, in such a way that the internal circumference of the plaited seals 16.1, 16.2 essentially corresponds to the outer circumference of the shaft (not shown) running through the sleeve member 15.1, so that the outer circumference of the plaited seals 16.1, 16.2 forms a tight fit with the internal circumference 15.1* of the sleeve member 15.1 and the shaft.
  • the thickness of the material of the plaited seals 16.1, 16.2 is arranged to essentially cover shy of distance the space arranged for it in the axial direction of the internal circumference 15.1* of the sleeve member 15.1.
  • the plaited seals 16.1, 16.2, of which the bearing assembly 13 according to the invention includes at least one or several, most commonly 2, are made of a material with the properties of high resistance to heat, reasonable compressibility, and low friction.
  • An example of such a material is pure graphite, which is preferably used in the bearing assembly 13 according to the invention. Pure graphite can resist temperatures of up to 1000°C, making it suitable for even very demanding bearing applications.
  • the ends 19 of the graphite plaits 16.1, 16.2 are preferably fitted together by bevelling, so that they also form a tight fit at the ends 19.
  • the thickness of the graphite plaits 16.1, 16.2 can be, for example 8 * 8 mm.
  • Cylindrical machining 18 is arranged in the second sleeve member 15.2, with an internal circumference that is dimensioned to receive both the shaft 26 of the damper 10 shown in Figure 1 and a bronze journal-bearing sleeve 14, in which the journal-bearing sleeve 14 is arranged, after the assembly has been assembled, to lie between the shaft and the cylindrical machining 18.
  • a protruding collar 14' is arranged at the end of the journal-bearing sleeve 14 and essentially connects with a protruding collar 15.2' arranged in the second sleeve member 15.2 ( Figure 4 ). Further, the external diameter of the collar 15.2' arranged in the first end of the second sleeve member 15.2 is set to correspond to the internal circumference 15.1* of the cylindrical machining arranged in the first sleeve member 15.1 for the sealing plaits 16.1, 16.2.
  • the connecting protruding collars 14', 15.2' of the said second sleeve member 15.2 and the journal-bearing sleeve 14 fit into the space arranged for the sealing plaits 16.1, 16.2 in the first sleeve member 15.1, so that they lie inside for a distance and form a so-called box seal by compressing the sealing plaits 16.1, 16.2.
  • the protruding collar 15.2' arranged in the sleeve member 15.2 can also be replaced with a separate ring (not shown), which can be placed freely in relation to the collar 14' of the journal-bearing sleeve 14.
  • the other operational components can also comprise several parts.
  • Bores 25.1 with internal threads are arranged in the first sleeve member 15.1, as well as bores 25.2 in the second sleeve member 15.2, at points corresponding to the bores 25.1.
  • Screws 17, which carry part of the loading caused by the flue gases on the dampers 10, and which hold the assembly 13 together, are fitted to the bores 25.1, 25.2.
  • the protruding collar 15.2' arranged in the second sleeve member 15.2 has also the secondary function of carrying the loading caused by the flue gases, which the securing screws 17 alone may not always necessarily be able to carry.
  • Figure 4 shows cross-sections of the first and second sleeve members 15.1, 15.2 used in the embodiment described.
  • the internal collar 15.1' machined in the first sleeve member 15.1 is also used to carry the shaft load arising from the damper 10. Additional collars can be fitted to the internal circumferences 15.1*, 15.2* of the first and second sleeve members 15.1, 15.2 to carry the shaft load.
  • the sealing plaits 16.1, 16.2 are fitted tightly into the space machined for them in the internal circumference 15.1*.
  • Figure 4 also shows the protruding collar 15.2' arranged in the second sleeve member 15.2 and the lubricant groove 21 arranged in the journal-bearing sleeve 14.
  • the loading acting on the seals 16.1, 16.2 can be adjusted, not only with the assembly screws 17 of the bearing assembly 13, but also by using, for example, the helical spring member 22 shown in Figure 4 , which is placed in the bottom of the second sleeve member 15.2, between the end of the shaft of the damper 10 and the bottom of the sleeve member 15.2.
  • the end of the spring member 22 on the shaft side is shaped so that it forms a very good fit against the end of the shaft. Altering the stiffness of the spring 22 allows a suitable level of tightness to be found for the assembly screws 17.
  • Figures 5 - 8 show another embodiment of the bearing assembly according to the invention.
  • the components and principle of this embodiment correspond essentially to the first embodiment described.
  • the first and second sleeve members 15.1, 15.2 are square plates.
  • the second sleeve member 15.2 is left open at both ends, allowing the shaft 26 of the damper 10 shown in Figure 1 to be pushed through it.
  • a protruding bearing tube 25 for the shaft 26 running through it is arranged at the end of the bearing assembly 13 and has devices 24 at its end that are as such known, for example, for fitting the operating linkage 12 shown in Figure 1 to the end of the shaft 26.
  • This embodiment is particularly intended for the operating side 27.1 of shut-off and control dampers, in which devices 12 are arranged to shut off and control the damper 10 ( Figure 1 ).
  • FIG. 9 A second preferred manner to adjust the load acting on the seals 16.1, 16.2 is shown in Figure 9 , which shows the first and second sleeve members 15.1, 15.2 and a spacer ring 23 placed between them.
  • the integrated bearing assembly according to the invention is preferably permanently lubricated, so that no lubrication connections at all are shown in it. Lubrication thus takes place during the assembly stage of the bearing assembly.
  • the bearing assembly according to the invention is assembled already in the machining stage. It can be installed in the frame structure 11 of the damper 10 in the application by, for example, welding the first sleeve member 15.1 to the frame 10.
