Description
Technical field
The utility model belongs to electric power Flue Gas Forced Draft Fan technical field, is specially adapted to a kind of adjusting rotor blade petiole thrust bearing seal arrangement of large-scale axial flow fan with adjustable moving blades.
Background technique
Along with the fast development of power industry; axial flow fan with adjustable moving blades is very crucial equipment in coal power generation system; axial flow fan with adjustable moving blades in running is once there be disorderly closedown; whole system all can be out of service; no small loss can be brought; therefore, axial flow fan with adjustable moving blades must be safe and reliable.In axial flow fan with adjustable moving blades, have a lot of bearing, in During Process of Long-term Operation, because oil seal structure is bad, cause oil leakage, bearing can not get good lubrication, and bearing is burnt, and causes axial flow fan with adjustable moving blades normally to run.
Model utility content
The utility model is intended to overcome above-mentioned defect, and object is to provide a kind of easy accessibility, good airproof performance, safe and reliable adjusting rotor blade petiole thrust bearing seal arrangement.
For achieving the above object, the technical solution adopted in the utility model its primarily of sharf, wheel hub, bearing cap, movable vane thrust-bearing, sharf nut composition.Sharf is buckled on wheel hub, overlaps successively load onto O RunddichtringO I, bearing cap, movable vane thrust bearing, O RunddichtringO III, seal ring II, O RunddichtringO IV, seal ring I, O RunddichtringO II from sharf microcephaly; The screw thread being loaded on sharf again by sharf nut is tightened, makes movable vane thrust bearing be in closed state; By straight pin patchhole, extend in half-arc groove, re-use snap ring and be buckled in groove; Sharf nut is provided with dismounting and mounting hole, is provided with oil hole simultaneously, adopt oil-hole plug to block.
Owing to adopting technique scheme, movable vane thrust bearing is in closed state by the utility model, simultaneously to enclosed space lubricating oil filling, by many places tight seal, ensure that bearing has oil lubrication in During Process of Long-term Operation, ensure that the steady running of axial flow fan with adjustable moving blades vane belt system; Set up installation and removal hole simultaneously, ensure convenient disassembly.
Accompanying drawing explanation
Fig. 1 is a kind of adjusting rotor blade petiole of the utility model thrust bearing schematic diagram of sealing device;
In the drawings: 1, sharf; 2, wheel hub; 3, O RunddichtringO I; 4, bearing cap; 5, movable vane thrust bearing; 6, seal ring I; 7, O RunddichtringO II; 8, oil hole; 9, oil-hole plug; 10, snap ring; 11, straight pin; 12, half-arc groove; 13, O RunddichtringO III; 14, seal ring II; 15, O RunddichtringO IV; 16, sharf nut; 17, screw thread; 18, dismounting and mounting hole; 19, groove; 20, hole.
Embodiment
Below in conjunction with accompanying drawing, explanation is described further to the utility model.
A kind of adjusting rotor blade petiole thrust bearing seal arrangement, it is primarily of sharf (1), wheel hub (2), bearing cap (4), movable vane thrust-bearing (5), sharf nut (16) composition.Its sharf (1) is buckled on wheel hub (2), overlaps successively load onto O RunddichtringO I (3), bearing cap (4), movable vane thrust bearing (5), O RunddichtringO III (13), seal ring II (14), O RunddichtringO IV (15), seal ring I (6), O RunddichtringO II (7) from sharf (1) microcephaly; The screw thread (17) being loaded on sharf (1) again by sharf nut (16) is tightened, movable vane thrust bearing (5) is made to be in closed state, be provided with oil hole (8) simultaneously, oil-hole plug (9) is adopted to block, movable vane thrust bearing (5) is in closed state, simultaneously to enclosed space lubricating oil filling, by many places tight seal, ensure that bearing has oil lubrication in During Process of Long-term Operation, ensure that the steady running of axial flow fan with adjustable moving blades vane belt system.By straight pin (11) patchhole (20), extend in half-arc groove (12), re-use snap ring (10) and be buckled in groove (19), prevent sharf nut (16) from loosening in running, cause seal leakage.Sharf nut (16) is provided with dismounting and mounting hole (18), service work for convenience detach.
Therefore, the utility model is a kind of easy accessibility, good airproof performance, safe and reliable adjusting rotor blade petiole thrust bearing seal arrangement.
Claims (1)
