Technical field:
The utility model relates to the technical fields of bearing, are specifically related to a kind of thrust bearing with oil scraper ring.
Background technique:
Sliding bearing is very widely used in all trades and professions, with the continuous extension of sliding bearing application field and technology
Be constantly progressive, the structure of sliding bearing also becomes increasingly complex.Horizontal water turbine, generator, blower, gear-box are used for as some
Etc. A seating sliding bearing generally require to bear certain axial thrust, in order to reduce design and manufacture cost, save axial space, push away
Power bearing is often combined into radial-thrust bearing with transverse bearing.Many times due to space limitations, radial-thrust bearing
Radial watt and the shared inflow pipeline all the way of thrust bearing shoe valve, feed to radial watt and thrust bearing shoe valve by the internal hole communicated or slot respectively.Only
Pressure by fuel feeding is to thrust bearing shoe valve and radial watt of fuel feeding, and the oil of thrust bearing shoe valve is a part of from the tile fragment gap of thrust bearing shoe valve and thrust bearing shoe valve
Run and without lubricated surface, while be not subject to the axial gap of thrust end thrust watt and thrust disc greatly with thrust end, flow resistance
It is small, so lubricating oil major part is leaked from thrust end is not subject to.Due to when axial force is larger and in the case where being frequently present of, thrust
Oil inlet quantity needed for watt is often bigger, and due to horizontal type structure, lubricating oil is influenced by gravity, and the thrust bearing shoe valve at top is often
There is the case where oil starvation, causes watt temperature excessively high or even tile kilning.

It is thrown to outside as surface, forms negative pressure in annular oil cavity at this time, oil is sucked into annular oil cavity from external oil feed line, thus effectively
The phenomenon that preventing the thrust bearing shoe valve especially thrust bearing shoe valve oil starvation at top and leading to tile kilning generation.And the protruding block of oil scraper ring lining is plugged on
The mounting groove of oil scraper ring matrix is interior, bulb plunger is embedded in shrinkage pool, and this connection structure makes oil scraper ring lining and oil scraper ring base
It is not only connected firmly between body, but also installing and dismounting is all very convenient between the two, oil scraper ring need to only be served as a contrast when installation and firmly be inserted
It connects in mounting groove, when disassembly only needs drawing oil scraper ring lining of exerting oneself outward.
Through the above scheme, the thrust bearing structure with oil scraper ring of the utility model is simple, can effectively seal and pushes away
Watt lubricating oil, and generation the phenomenon that can effectively prevent the thrust bearing shoe valve especially thrust bearing shoe valve oil starvation at top and lead to tile kilning.
As a preference of the above scheme, the annular oil cavity is connected by oilhole and half circle groove with external oil inlet pipe
Logical, by the half circle groove and oilhole and annular oil cavity to thrust bearing shoe valve fuel feeding, the other half passes through the external oil inlet pipe half
Half circle groove and oil groove are to radial watt of fuel feeding.
As a preference of the above scheme, the oil scraper ring matrix is made of carbon steel material, oil scraper ring matrix specific thrust
Watt low 2-3mm in surface.
As a preference of the above scheme, the oil scraper ring lining is by antifriction material polytetrafluoroethylene (PTFE) or bearing metal system
At oil scraper ring contrasts the low 0.1-0.5mm in thrust bearing shoe valve surface, and is only distributed at oil scraper ring matrix outer circle.
As a preference of the above scheme, the protruding block of the oil scraper ring lining is cylindrical, on oil scraper ring matrix
Mounting groove is rounded.
As a preference of the above scheme, the shrinkage pool is evenly distributed on oil scraper ring lining in a ring, and bulb plunger is in
Annular is evenly distributed on the inner wall of mounting groove.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
