Abstract
The utility model discloses a single-base double-row elastic metal plastic thrust bearing which comprises a fan-shaped steel base (1); a left elastic metal plastic composite pad face (2) and a right elastic metal plastic composite pad face (3) are distributed circumferentially and both have a length-width ratio less than 1:1.2; and an oil-guide groove (4) is arranged between the left elastic metal plastic composite pad face (2) and the right elastic metal plastic composite pad face (3). The single-base double-row elastic metal plastic thrust bearing not only meets the design requirements of compact structure and low cost for oil tank, but also reduces the unit pressure of the thrust bearing, improves the lubricating condition of the high-load region close to the oil discharge side, effectively reduces the temperature rise during the operation, and improves the operational reliability of the thrust bearing. Additionally, the number of the plastic thrust support is reduced according to the number of the fan-shaped steel base. The single-base double-row elastic metal plastic thrust bearing also has the advantages of simple structure, low cost and convenience for installation and maintenance.
Description
Technical field:
The utility model relates to a kind of elastic metal-plastic thrust bearing pads, especially a kind of simple in structure, can improve lubricating condition, effectively reduce cost and move temperature rise, improve the double elastic metal-plastic thrust bearing pads of single matrix of thrust bearing shoe valve operational reliability.
Background technique:
Elastic metal-plastic thrust bearing pads is a kind of novel thrust-bearing, has been widely used in industries such as hydraulic generator set thrust bearing, gear-box thrust-bearing because of it has many excellent properties.Existing elastic metal-plastic thrust bearing pads is characteristics of elastic metallic plastic composite tiling of soldering on fan-shaped steel base all, during use the polylith elastic metal-plastic thrust bearing pads is installed in the tubular fuel tank and forms ring-type, the external diameter decision fuel tank size of thrust bearing shoe valve.Structure is compact more to reduce cost in order to make, and the difference that will reduce external diameter and dwindle thrust bearing shoe valve external diameter and internal diameter simultaneously in order to reduce the specific pressure of thrust bearing shoe valve, takes to strengthen the width method increase compression area of thrust bearing shoe valve usually.Width is crossed senior general and is caused thrust bearing shoe valve when operation, and the distance of lubricant oil from the oil-feed limit to fuel-displaced limit is long, makes the high-mechanic district poor lubrication near fuel-displaced limit, and the oil slick thickness attenuate easily causes the tile kilning accident; In addition, heating value one timing on the thrust bearing shoe valve unit area, gross calorific power will increase with every tiling width, reduce the reliability of thrust bearing shoe valve.Therefore, the Aspect Ratio of elastic metal-plastic thrust bearing pads is rationally essential, generally should not surpass 1:1.2, and this is one of important parameter that guarantees the thrust bearing shoe valve safe operation.Because existing thrust bearing shoe valve is characteristics of elastic metallic plastic composite tiling of soldering on fan-shaped steel base, as satisfy the condition of the Aspect Ratio of thrust bearing shoe valve less than 1:1.2, has only the quantity that increases thrust bearing shoe valve, this just need increase the support device quantity of thrust bearing shoe valve thereupon, make structure complicated, not only increase cost, make installation, maintenance loaded down with trivial details simultaneously.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, provide a kind of simple in structure, can improve lubricating condition, effectively reduce cost and move temperature rise, improve the double elastic metal-plastic thrust bearing pads of single matrix of thrust bearing shoe valve operational reliability.
Technical solution of the present utility model is: the double elastic metal-plastic thrust bearing pads of a kind of single matrix, fan-shaped steel base is arranged, on described fan-shaped steel base, be provided with circumferencial direction distribute and Elongation all less than left characteristics of elastic metallic plastic composite tiling and the right characteristics of elastic metallic plastic composite tiling of 1:1.2, be provided with oil guide slot between left characteristics of elastic metallic plastic composite tiling and the right characteristics of elastic metallic plastic composite tiling.
The oil-feed limit of described left characteristics of elastic metallic plastic composite tiling and right characteristics of elastic metallic plastic composite tiling is a wedge shape.
The width of described oil guide slot is 10～50mm, and its degree of depth is the thickness of characteristics of elastic metallic plastic composite tiling.
The utility model is to be provided with the characteristics of elastic metallic plastic composite tiling of the wide ratio of two block lengths less than 1:1.2 on a fan-shaped steel base, and between two tilings, be provided with oil guide slot, the designing requirement that can satisfy the Oiltank structure compactness, reduces cost, can also reduce the unit pressure of thrust bearing shoe valve, also can improve simultaneously high-mechanic district lubricating condition near fuel-displaced limit, effectively reduce the operation temperature rise, improve the thrust bearing shoe valve reliability of operation.In addition, the thrust bearing shoe valve support device reduces along with fan-shaped steel base quantity, and not only simple in structure, cost reduces, and installation, maintenance is more prone to.

Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the plan view of Fig. 1.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: have with the identical fan-shaped steel base 1 of prior art, on described fan-shaped matrix 1 soldering have along the circumferential direction distribute and Elongation all less than 1: 1.2 left characteristics of elastic metallic plastic composite tiling 2 and right characteristics of elastic metallic plastic composite tiling 3, be provided with oil guide slot 4 between left side characteristics of elastic metallic plastic composite tiling 2 and the right characteristics of elastic metallic plastic composite tiling 3, width is 10～50mm preferably, and its degree of depth is the thickness of characteristics of elastic metallic plastic composite tiling.The oil-feed limit of described left characteristics of elastic metallic plastic composite tiling 2 and right characteristics of elastic metallic plastic composite tiling 3 all is processed into and is beneficial to the wedge shape of setting up the hydrldynamic pressure lubrication oil film.
