Technical field
The utility model belongs to field of mechanical technique, especially relates to a kind of novel thrust bearing shoe valve.
Background technique
Thrust bearing shoe valve is also referred to as thrust-bearing, is the end thrust of balancing rotor.Thrust bearing shoe valve is widely used in steam turbine, water turbine, water pump etc.It is to be fixed on the supporting mass freedom and flexibility to swing, and consists of with runner plate that dynamic pressure oil film is lubricated, carrying, the fan-shaped part that is made of friction surface layer and unbaked tile body.Existing thrust bearing shoe valve is mainly made by steel billet and coal, because thrust bearing shoe valve Environmental Conditions temperature is high, dust is large and insufficient lubrication, also force down owing to this watt ratio, friction factor is large, adaptive temperature is low, mechanically deformation and thermal distortion to tiling can not self be adjusted, but burning accident often occurs, and cause very large loss.In addition existing thrust bearing shoe valve also exists: complex structure, inconvenience is installed, and poor stability, cost is high, wear-resistant ability, the problem such as working life is short.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of elastic metal-plastic thrust bearing pads [application number: 200620021793.6], it is on the metal unbaked tile of traditional thrust bearing shoe valve, polytetrafluoroethylene plastic plate is tied in subsides, at that face of plastic board that pastes knot, the silk holder that the bronze wire spring wire that has die casting to advance is made, plastic board/belt silk support and metal unbaked tile junction plane edge seam crossing are welded into the R6 form continuously with scolding tin; Two longitudinal end grindings of plastics tiling go out each two inclined-plane, and the angle on two inclined-planes and watt plane is 45 ° of oil inlet ends, 12 °, 12 °, 45 ° of oil outlet ends.
Such scheme has solved the problem of the wear-resistant ability of existing thrust bearing shoe valve to a certain extent, but this scheme still exists: complex structure, inconvenience is installed, and poor stability, easily loosening in the using process, cost is high, the problem that working life is short.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, easy for installation, the novel thrust bearing shoe valve that stability is high.
For achieving the above object, the utility model has adopted following technical proposal: this novel thrust bearing shoe valve, comprise the thrust bearing shoe valve body that is fan-shaped, described thrust bearing shoe valve body comprises wearing layer, transition layer and the basic unit that from up to down sets gradually, it is characterized in that, described wearing layer is made by nonmetallic material, the lower surface of described thrust bearing shoe valve body is provided with fan-shaped mounting plate in the circumferential direction of the circle, described fan-shaped mounting plate and thrust bearing shoe valve body are connected as a single entity structure, and are provided with mounting hole at fan-shaped mounting plate.
In above-mentioned novel thrust bearing shoe valve, described fan-shaped mounting plate is arranged on the middle part of thrust bearing shoe valve body.
In above-mentioned novel thrust bearing shoe valve, the central lines of the center line of described fan-shaped mounting plate and thrust bearing shoe valve body.
In above-mentioned novel thrust bearing shoe valve, the equal in length of the length of described fan-shaped mounting plate and thrust bearing shoe valve body.
In above-mentioned novel thrust bearing shoe valve, the width of described fan-shaped mounting plate is the 1/2-2/3 of the width of thrust bearing shoe valve body.
In above-mentioned novel thrust bearing shoe valve, described wearing layer is made by polytetrafluoroethylmaterial material; Described transition layer is made by copper wire; Described basic unit is made by steel.
Compared with prior art, the advantage of this novel thrust bearing shoe valve is: simple and reasonable, easy for installation, stability is strong, be difficult for during use becoming flexible, cost is low, and wear resistance is good, friction factor is little, have good insulating properties, alleviate local superheating and bring impact on watt base, have the performance of self-regulated, load is evenly distributed, long service life.
