Abstract
The utility model relates to a self-lubricating spherical surface sliding bearing, which comprises an evenly divided outer ring and an inner ring. The utility model is characterized in that: a reinforced polyfluortetraethylene cushion coat is embedded into the evenly divided outer ring between the inner ring and the external outer ring. The self-lubricating effect is good, and the pressure bearing load is large and safe. The utility model not only is applicable for the supporting hinge of the hydrotechnical radial gate, but also is applicable for various mechanical devices with a heavy load and a low friction such as the fixed wheel of the large plane gate, hanging head part of the hydraulic headstock gear of the hydrotechnical gate and mechanical joint bearing parts in such industries as petroleum, chemical engineering, aviation and engineering machinery industry.
Description
Technical field:
The utility model belongs to the improvement of selflubricating sphere sliding bearing structure, props up the reinforced TFE selflubricating sphere sliding bearing of hinge especially for the water conservancy project gates of segmental shape.
Background technique:
At present, the used selflubricating sphere sliding bearing in home and abroad is mainly by Germany, Japanese import.The like product of domestic manufacturers' recent development has two kinds: a kind of is that inner ring arc at spherical bearing is coated with the acetal plastic that covers the following thickness of 0.5mm or without the polytetrafluoroethylplastic plastic that strengthens modification.These products all exist the pressure-bearing deficiency problem: the former reduces significantly at inner ring punching back, its load, the lubriation material that injects and the load compression ratio of metal are inconsistent, forming the oiling agent extrusion runs off, can not play the self-lubricating function of big load long-time running, increase the unsafe factor of hydraulic structure operation thus; And the latter's shortcoming is that the plastics of metal surface coating are without strengthening modification, then reduce in conjunction with substrate intensity, the compressive strength of himself is low, the service wear amount is big, is difficult to bear long-term big load service condition, the normal operation after the water that can not bear sediment charge enters.
The model utility content:
The purpose of this utility model is in order to overcome above-mentioned deficiency, to provide a kind of self-lubricating effect good, and the pressure-bearing load is big, safety, the selflubricating sphere sliding bearing that usage range is wide.
The purpose of this utility model is achieved in that
The utility model selflubricating sphere sliding bearing, comprise a minute outer ring, inner ring, it is characterized in that inner ring, to the reinforced TFE bed course that is embedded in minute outer ring is arranged between minute outer ring, the reinforced TFE bed course can adopt and strengthen poly-tetrafluoro NL150 self lubricating material and make.
Above-mentioned being embedded in the reinforced TFE bed course in minute outer ring is with respect to the outside aligning of spherical bearing central point angle α 〉=2 °.
Above-mentioned spherical bearing external diameter is 30mm～1500mm.
The fitted shaft that the utility model and water conservancy project gates of segmental shape prop up on the hinge is equipped.Load passes to inner ring by a minute outer ring is passed to the enhancing polyethylene bedding by bed course, passes to fitted shaft by inner ring, by fitted shaft Load Transfer is passed in the waterwork basis to behind the bearing support again.
The utility model sliding bearing inner ring, to the loading intensity of the reinforced TFE bed course bearing surface between minute outer ring more than or equal to 150MPa, under the operating conditions that contains silt aqueous medium pressurized, friction factor is lower than 0.15 in the lifetime; Because being whole circle, selflubricating reinforced TFE bed course is embedded in the outer ring, be not that mat surface applies lubriation material, self-lubricating effect is good, guarantees a stable friction factor and a good operation of hinge all the time so obtain service life, and hydraulic structure safety is secure etc.The utility model possesses minimum 2 ° aligning condition, makes hydraulic gate prop up that hinge is hung head at hydraulic hoist, fixed wheel has obtained good installation and stress condition; In installing, a hinge of longspan created the condition that makes things convenient for; Fundamentally solve a hinge and born the difficulty of axial load, prolonged the life-span that gate props up the hinge safe operation significantly.The utility model usage range is wide, be applicable to that not only the water conservancy project gates of segmental shape props up on the hinge, and be applicable to the various machinery of the low frictional resistance of heavy duty, hang the mechanical joint bearing portion of head position and oil, chemical industry, aviation, construction machinery industry etc. as fixed wheel, the hydraulic gate hydraulic hoist of large plane gate.
