The rubber strip has the advantages that the underwater concealment of the submarine is good owing to the insertion strip type rubber bearing comprising the rubber strip, and the rubber components of the rubber strip are reasonable in composition.
Description
Technical field
The present invention relates to a kind of sizing material composition of filler rod type rubber bush bearing rubber lath of filler rod type rubber bush bearing rubber lath, particularly a kind of submarine stern tube shaft of submarine stern tube shaft.
Background technique
Arbor is the rotary drive part in machinery, bearing be stationary axle in equipment position, support axle load and reduce axle and body between the component that rub.Bearing has roller bearing and axle sleeve.
Submarine stern tube shaft is the stern tube shaft of submarine, and submarine stern tube shaft stretches out from the rear portion of submarine, and the rear end of stern tube shaft outside submarine connects propeller cavitation, and the front end of stern tube shaft in submarine is connected with motor by gear-box or coupling drive.The size of stern tube shaft is very large, and load is also very large.Stern tube shaft is arranged on two bearings, and one is rear bearing, the part that rear bearing contacts with water at hull, another is bearing, on the cabin skeleton of bearing in cabin, be tailing axle cabin between former and later two bearings, the dependence of tailing axle cabin is arranged on the seal ring on forward and backward bearing side and realizes airtight.
The bearing of submarine stern tube shaft is axle sleeve, and submarine stern tube shaft bearing axle sleeve is filler rod type rubber bush bearing.Filler rod type rubber bush bearing has cylindrical bearing sleeve, the inner circumference of bearing sleeve is evenly equipped with the length direction rubber lath parallel with the axis of bearing sleeve, rubber lath has metal lath skeleton, metal lath skeleton outside is enclosed with rubber layer, below metal lath skeleton, be evenly equipped with screw, it below rubber lath, is one section of cylndrical surface with certain radian, on rubber layer below rubber lath, there is the circular hole relative with screw below metal lath skeleton, below rubber lath, the diameter of the diameter of cylndrical surface and the inner cylindrical surface of bearing sleeve is identical, rubber lath is to be embedded on the inner cylindrical surface of bearing sleeve with screw, rubber lath on the uniform interior cylinder that is embedded in bearing sleeve surrounds cylindrical shape, with bearing sleeve composition filler rod type rubber bush bearing, the rubber lath that submarine stern tube shaft is through filler rod type rubber bush bearing surrounds in cylinder, above rubber lath, stick together composition friction pair with the external cylindrical surface of submarine stern tube shaft.
Submarine relies on stern tube shaft to drive propeller cavitation to rotate and moves under water under water.The bearing of submarine stern tube shaft not only to be used for fixing stern tube shaft position, support stern tube shaft load and reduce stern tube shaft and cabin frame between friction factor, the most important thing is for the underwater disguise of submarine, the noise producing because of friction when submarine stern tube shaft rotates in bearing can not be large, the size of above-mentioned noise is relevant with the rubber size composition of rubber lath in friction pair, and rubber size composition is the weight portion of constituent and each constituent of sizing material.
In above-mentioned friction pair, the rubber size of rubber lath forms except meeting the rubber lath of making to requirement of mechanical strength, friction factor between rubber lath and the submarine stern tube shaft of steel that also requires to make to make is as much as possible little, the noise producing because of friction just can make submarine stern tube shaft rotate in filler rod type rubber bush bearing time is very little, is conducive to the underwater disguise of submarine.
In prior art, the rubber size composition of the rubber lath in the filler rod type rubber bush bearing of submarine stern tube shaft is not quite reasonable, friction factor between the rubber lath made from this rubber size and the submarine stern tube shaft of steel is not very low, in using process, the noise that submarine stern tube shaft produces because of friction while rotation in filler rod type rubber bush bearing is not little, and the filler rod type rubber bush bearing of the submarine stern tube shaft made from this rubber lath affects the underwater disguise of submarine.
Summary of the invention
The object of the invention is in order to overcome above-mentioned deficiency the bearing rubber lath of the submarine stern tube shaft that the friction factor of the composition that proposes a kind of sizing material rationally, between rubber lath and the submarine stern tube shaft of steel made is less.
The present invention is achieved using the following method.
The bearing rubber lath of submarine stern tube shaft has metal lath skeleton, metal lath skeleton outside is enclosed with rubber layer, below metal lath skeleton, be evenly equipped with screw, it below rubber lath, is one section of cylndrical surface with certain radian, on rubber layer below rubber lath, there is the circular hole relative with screw below metal lath skeleton, in rubber lath, the weight portion of the sizing material of rubber layer composition and each component is: Nitrile Rubber 40:60, Nitrile Rubber 26:40, zine oxide: 4.5 ~ 5.5, stearic acid: 1.8 ~ 2.2, antioxidant A: 1.35 ~ 1.65, antioxidant D: 1.8 ~ 2.2, carbon black M550:9 ~ 11, mixed gas carbon black: 9 ~ 11, coumarone: 1.8 ~ 2.2, DCP crosslinking agent: 1.8 ~ 2.2, coupling agent kh-570: 0.9 ~ 1.0, anti-static agent SP:4.5 ~ 5.5, dibutyl ester: 9 ~ 11, paraffin oil: 9 ~ 11, plumbago: 5.4 ~ 6.6, carbon fiber: 7.2 ~ 8.8, bronze powder: 4.5 ~ 5.5, silver powder: 4.5 ~ 5.5, molybdenum disulphide powder: 4.5 ~ 5.5.
Below the present invention, the diameter of cylndrical surface is identical with the inner cylindrical surface diameter of the cylindrical bearing sleeve of the filler rod type rubber bush bearing front shaft sleeve of submarine stern tube shaft.
When installation, the present invention is embedded on the inner cylindrical surface of bearing sleeve with screw, make length direction of the present invention parallel with the axis of bearing sleeve, the present invention on the uniform interior cylinder that is embedded in bearing sleeve surrounds cylindrical shape, with bearing sleeve composition filler rod type rubber bush bearing, the bar of the present invention that submarine stern tube shaft is through filler rod type rubber bush bearing surrounds in cylinder, the column jacket side face of submarine stern tube shaft and stick together composition friction pair above the cylindrical of rubber lath.
The sizing material composition of rubber layer of the present invention not only has the component of the requirement of mechanical strength that can meet the rubber lath of making, can reduce in addition the component of friction factor between the rubber product made and steel, as: paraffin oil, graphite, carbon fiber, bronze powder, silver powder and molybdenum disulphide powder, the rubber lath mechanical strength made from this sizing material is higher, and between the submarine stern tube shaft of rubber lath and steel, friction factor is lower.When use, submarine stern tube shaft is in filler rod type rubber bush bearing in rotary course, and the noise producing because of friction is less.The filler rod type rubber bush bearing of the submarine stern tube shaft made from this rubber lath makes the underwater disguise of submarine better.The rubber size composition of this rubber lath rationally.
