Description
Technical field
The present invention relates to resilient sleeper-bearing under a kind of iron chair.Be used for the high-speed railway fastener system and play cushioning effect.Belong to high ferro fastener technology field.
Background technology
Resilient sleeper-bearing is the crucial elastomer element of Line for Passenger Transportation fastener system under the iron chair, undertaking the vibration that slows down from rail, relaxing wheel-rail impact, disperseing the wheel load effect, stoping rail creeping, to increase track insulation etc. all multi-functional, its Key Performance Indicator requires the sound ratio of rigidity less than 1.35, can resist anti-3,000,000 fatigues.Present original vibration isolation rubber product only is applicable to the low speed railway of design speed per hour below 200km/h, and every technical indicator all can't satisfy the instructions for use of high ferro fastener system.
What high-speed railways was used now all is external casting type polyurethane (C-PU) backing plate, this backing plate cost height, and intensity is low, and the high-temperature modulus decay is big, the hydrolysis poor stability.And because the limitation of pouring technology, the quiet range in stiffness fluctuation of gained finished product is bigger, directly has influence on the riding comfort of bullet train.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of cost low, the intensity height, high-temperature modulus decay is little, resilient sleeper-bearing under the less rubber pange iron chair of the quiet range in stiffness fluctuation of hydrolysis good stability and finished product.
The object of the present invention is achieved like this: resilient sleeper-bearing under a kind of rubber pange iron chair, and described backing plate outward appearance is rectangular-shaped, and backing plate the right and left respectively has a pilot hole, the backing plate surface skining, backing plate inside is cellular closed pore foaming structure;
It is that the rubber composite of 7:3 is done the main body material that described backing plate adopts the ratio of ethylene propylene diene rubber and natural rubber, this kind rubber composite is with low cost, the hydrolysis good stability, ethylene propylene diene rubber in the rubber composite plays ageing-resistant effect, natural rubber then plays raising intensity, reduces the effect of the output ratio of Q-switching to free running;
Described backing plate adopts the high superfine calcinated potter's clay (fineness 1500 orders) of reinforcement to do filling, because superfine calcinated potter's clay particle diameter is little, so reinforcement is higher, can make backing plate have higher strength; And the shape of particle of potter's clay is the hexagon sheet structure of rule, be laminated crystalline after assembling, compare with the disordered chain of carbon black is dendritic, this structure of potter's clay can better reduce the frictional heat of rubber molecular chain when being subjected to external force, thereby realize low hysteresis on the whole, fatigue proof purpose;
Described backing plate also adopts pore former HD-1(Celogen Az and the sodium acid carbonate composite with mass ratio 3:1) as foaming system, vulcanizing agent S-350(sulphur and dithiodimorpholine are composite with mass ratio 1:3.5) and accelerant CZ (benzothiazole time yellow acid amides) formation vulcanizing system, described pore former HD-1, the ratio of vulcanizing agent S-350 and accelerant CZ three's quality is pore former HD-1: vulcanizing agent S-350: accelerant CZ=5:2:3, by adjusting vulcanizing system curingprocess rate and expansion rate are complementary, make this backing plate form surface skining, inside is cellular closed pore foaming structure, this structure can reduce the sound ratio of rigidity of backing plate greatly, can remain on the sound ratio of rigidity about 1.25, can satisfy the output ratio of Q-switching to free running in the high ferro fastener system fully less than 1.35 requirement.
Described backing plate uses the quality of materials mark as follows:
70 parts of ethylene propylene diene rubbers
30 parts of natural rubbers
50 parts of fineness 1500 purpose calcinated argils
5 parts of pore former HD-1
2 parts of vulcanizing agent S-350
3 parts of accelerant CZs.
Described backing plate has decorative pattern shape structure in two surfaces up and down, can increase the force of sliding friction between backing plate and the sleeper, makes quiet rigidity keep stable state, has significantly reduced the vibration of the rail that produces owing to the quiet rigidity difference in size of backing plate.
The invention has the beneficial effects as follows:
In sum, resilient sleeper-bearing under the rubber pange iron chair of the present invention, with low cost, the intensity height, the high-temperature modulus decay is little, the hydrolysis good stability, low hysteresis, endurance, the output ratio of Q-switching to free running reaches below 1.3, and quiet rigidity remains within the less fluctuation range; Ageing-resistant, have excellent weather resistance the hot strength height.Can be good at satisfying the critical index of high ferro fastener system, overall performance is better than building type polyurethane backing plate abroad.
