Abstract

The utility model relates to a thrust bearing structure with an oil slinger, which protects a rotating shaft against abrasion, the oil slinger is composed of an oil slinger basal body and an oil slinger liner through bonding, wherein the oil slinger liner is made of friction bearing polyfluortetraethylene or bearing alloy, the surface of the oil slinger liner is only 0.1 to 0.5 mm lower than that of thrust pads so that lubrication oil is effectively prevented from running away from a clearance between the thrust pads, meanwhile because an oil chamber for enabling relative sealing to be formed between the thrust pads exists in the oil slinger during the operation, a thrust plate is enabled to form a pump function during the operation and ensures that lubricating oil is sucked to the lubricated surfaces of the thrust pads from an oil inlet pipe, and tile burning due to oil shortage can be effectively prevented. The utility model has the characteristics of simple structure, good sealing effect and the like.

Description

A kind of thrust bearing with flinger ring

Technical field

The utility model relates to a kind of bearing structure, especially a kind of thrust bearing with flinger ring.

Background technique

Sliding bearing is very extensive in the application of all trades and professions, and along with the continuous expansion and the continuous advancement in technology of sliding bearing application, the structure of sliding bearing also becomes increasingly complex.Be used for horizontal water turbine, generator as some, blower fan, seat formula sliding bearings such as gear-box often need to bear certain end thrust, in order to reduce design and manufacture cost, save axial space, and thrust-bearing often is combined into radial-thrust bearing with radial bearing.Many times because the restriction in space, radial-thrust bearing radially watt and shared one road inflow pipeline of thrust bearing shoe valve, hole that communicates by inside or groove feed to respectively radially watt and thrust bearing shoe valve.The pressure that only depends on fuel feeding is to thrust bearing shoe valve and watt fuel feeding radially, and the oil part of thrust bearing shoe valve is walked and without lubricated surface from the tile fragment interval training of thrust bearing shoe valve and thrust bearing shoe valve, simultaneously big the and thrust end of the axial clearance of bearing thrust end thrust watt and thrust disc, flow resistance are not little, so the never bearing thrust end leakage of lubricant oil major part.Because under the bigger and ever-present situation of axial force, the required oil inlet quantity of thrust bearing shoe valve is often bigger, and owing to horizontal type structure, lubricant oil is subjected to the influence of gravity, and the situation of oil starvation often appears in the thrust bearing shoe valve at top, causes the too high even tile kilning of watt temperature.

Summary of the invention

The purpose of this utility model is a kind of simple in structure, the thrust bearing that can effectively seal the band flinger ring that pushes away watt lubricant oil of design.The technical solution of the utility model is so to realize:

A kind of thrust bearing with flinger ring, comprise thrust bearing shoe valve, flinger ring, thrust bearing shoe valve is installed in the flinger ring hole uniform in the form of a ring, described flinger ring comprises the flinger ring matrix and is located at the flinger ring lining of one side, both bond together, 2-3mm is hanged down on flinger ring matrix specific thrust watt surface, and flinger ring contrasts the low 0.1-0.5mm in thrust bearing shoe valve surface.

The flinger ring of the utility model design is to be made of flinger ring matrix and flinger ring lining, the flinger ring matrix is made by carbon steel material, in order to prevent the rotating shaft of wearing and tearing, the flinger ring lining is made by antifriction material teflon or bearing metal, flinger ring matrix and bonding being integral of flinger ring lining.One group of circular thrust bearing shoe valve is installed in the flinger ring hole uniform in the form of a ring, low 0.1～the 0.5mm of flinger ring lining surface ratio thrust bearing shoe valve working surface, and only be distributed in flinger ring matrix cylindrical place, flinger ring matrix surface specific thrust watt low 2～3mm, flinger ring lining and thrust bearing shoe valve and the rotating shaft of band thrust disc form an annular oil cavity, prevent that effectively lubricant oil from leaking from the tile fragment gap location of thrust bearing shoe valve.Half communicates outside in-line with oil pocket by half circle groove and oilhole and to the thrust bearing shoe valve fuel feeding; Second half by half circle groove and oil groove to watt fuel feeding radially.Be with thrust disc rotating shaft rotation during operation and form oil film with thrust bearing shoe valve, simultaneously since the thrust disc external circe speed of band thrust disc rotating shaft greater than inner circle-line speed, lubricant oil is thrown to the outside by the thrust bearing shoe valve working surface, form negative pressure in the oil pocket this moment, oil is sucked oil pocket from outside oil feed line, thus effectively prevent thrust bearing shoe valve particularly the top the thrust bearing shoe valve oil starvation and cause the phenomenon of tile kilning to take place.

This structure particularly suitable bears the radial-thrust bearing of bidirectional propulsion.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of the present utility model;

Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.

Embodiment

Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.

Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, a kind of thrust bearing with flinger ring, comprise thrust bearing shoe valve 1, flinger ring, thrust bearing shoe valve 1 is installed in the flinger ring hole 12 uniform in the form of a ring, described flinger ring comprises flinger ring matrix 7 and is located at the flinger ring lining 8 of one side, both bond together, flinger ring matrix 7 is made by carbon steel material, in order to prevent the rotating shaft of wearing and tearing, flinger ring lining 8 is made by antifriction material teflon or bearing metal, the flinger ring matrix 7 specific thrusts watt low 3mm in 1 surface, flinger ring serve as a contrast the 8 specific thrusts watt low 0.3mm in 1 surface.And only be distributed in flinger ring matrix 7 cylindrical places.

Flinger ring lining 8 forms an annular oil cavity 6 with thrust bearing shoe valve 1 and band thrust disc rotating shaft 2, prevents that effectively lubricant oil from leaking from the tile fragment gap location of thrust bearing shoe valve 1.Half communicates outside in-line with oil pocket 6 by half circle groove 10 and oilhole 9 and to thrust bearing shoe valve 1 fuel feeding; Second half by half circle groove 10 and oil groove 5 to watt fuel feeding radially.

Be with thrust disc rotating shaft 2 rotations during operation and form oil film with thrust bearing shoe valve 1, simultaneously since the thrust disc external circe speed of band thrust disc rotating shaft 2 greater than inner circle-line speed, lubricant oil is thrown to the outside by thrust bearing shoe valve 1 working surface, form negative pressure in the oil pocket 6 at this moment, oil is sucked oil pocket 6 from outside oil feed line, thus effectively prevent thrust bearing shoe valve 1 particularly the top the thrust bearing shoe valve oil starvation and cause the phenomenon of tile kilning to take place.

Claims
