Abstract
The utility model discloses a tilting type thrust bearing capable of increasing the axial thrust, which comprises a thrust shaft bracket (1), a thrust disc (3), a base ring (4), a standard block (5) and a thrust shoe (6); an oil inlet (2) and an oil outlet (7) are formed on the thrust shaft bracket (1); the thrust shoe (6) takes the shape of a sector ring; the radius of an inner sector ring is 1.125-1.129 times of that of the conventional standard tilting type thrust bearing; and the radius of an outer sector ring is 1.054-1.058 times as large as that of the conventional standard tilting type thrust bearing. The tilting type thrust bearing enhances the bearing capacity of the thrust bearing, solves the problem that the thrust shoe is seriously worn and burnt under high load of the steam turbine, ensures the safe long-term operation of the machine set and brings better economic benefits for enterprises.
Description
Technical field
The utility model relates to a kind of tilting-type thrust-bearing that increases end thrust, belongs to the thrust-bearing technical field.
Background technique
Along with development of science and technology, many old-fashioned production lines can not satisfy the demand of productivity, and the existing method of taking mostly is to be transformed and reach energy-saving and production-increase old equipment.But in the process that existing equipment is transformed, some parts involvement aspect too extensively be inconvenient to replace (as key foundation parts such as rotating shafts), shows the target of taking to finish with the method for replacement related accessory technological transformation more.As produce that air compressor in 300,000 tons of synthetic ammonia installations drives that the former design of turbine selects for use per year be 7 " the tilting-type thrust-bearing comes bearing axial pushing force.Because after synthetic ammonia carried out energy-saving and production-increase 22% transformation in 1996, air compressor is transformed with the needs of air quantity for satisfying the device volume increase, but driving steam turbine is transformed, improved compressor inflate quantity has increased by 10 tons/hour on intrinsic basis, cause the driving steam turbine increase of exerting oneself.After steam turbine is exerted oneself and is increased, rotor is the end thrust increasing of back generation down in working order, former design selects 7 for use " the bearing loading capability and can not satisfy the requirement that rotor axial thrust increases of tilting-type thrust-bearing; thereby cause the thrust bearing shoe valve Babbitt to produce severely subnormal abrasion and tile kilning phenomenon; the result brings bigger safe shadow to suffer to unit operation;, cause 2,000,000 yuan/day economic loss every day to enterprise in case the tile kilning repairing of stopping occurs.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of tile kilning probability that reduces is provided, increases the tilting-type thrust-bearing of end thrust, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: it comprises thrust pedestal 1, thrust button 3, basic ring 4, level piece 5 and thrust pad 6, on thrust pedestal 1, offer filler opening 2 and oil outlet 7, annular is fanned in being shaped as of thrust pad 6, the radius of interior wing ring is 1.125～1.129 times of existing standard tilting-type thrust-bearing radius, and the radius of outer sector circular is 1.054～1.058 times of existing standard tilting-type thrust-bearing radius.
Filler opening 2 is positioned at the bottom of thrust pedestal 1.
The area of filler opening 2 is 1.10～1.14 times of existing standard tilting-type thrust-bearing filler opening area.
The diameter of oil outlet 7 is 1.02～1.04 times of existing standard tilting-type thrust-bearing oil outlet diameter.
The internal diameter of basic ring 4 is 1.02～1.04 times of standard basic ring.
The length of level piece 5 is 1.04～1.05 times of correct level block length, and wide is wide 1.03～1.05 times of correct level piece, and height is high 1.02～1.04 times of correct level piece.
Compared with the prior art; the utility model is by strengthening basic ring, level piece, thrust bearing shoe valve area in the bearing unit; change lubricant oil oil-feed orientation and increase oil inlet quantity and improved lubricating condition; simultaneously by after the means such as increase oil drain out size increasing recirculating oil quantity; improved the bearing capacity of thrust-bearing; solved thrust bearing shoe valve heavy wear and tile kilning present situation under the steam turbine high capacity, guaranteed the unit safety long-term operation, for enterprise has brought favorable economic benefit.
