The polymer engineering plastic bush has the advantages of easy processing, good abrasion resistance, uneasy damage, convenient maintenance and lower price.
Description
Technical field
The utility model belongs to the bearing shell technical field.
Background technique
At present, the equipment of press for extracting juice sugar machine one class of using as sugar refinery, the supporting bearing shell that its squeeze roller use generally adopts cu bearing liner.Cu bearing liner is the price height not only, and because of the hardness height, is difficult for processing, is difficult for spatula, and is big to the squeezing roller shaft neck wearing and tearing, causes badly damaged for behind the oil starvation squeezer axle journal and even scraps, and cause greater loss to sugar refinery, and maintenance labor intensity is big, maintenance expenses is high.
Summary of the invention
The purpose of this utility model provides a kind of just and is easy to process in order to solve the deficiency that above-mentioned prior art exists, not fragile, be convenient to safeguard and macromolecule engineering plastic bearing shell that price is lower.
The purpose of this utility model is achieved by the following technical solution.
A kind of macromolecule engineering plastic bearing shell, this bearing shell be by the macromolecule engineering plastic production, offers oil groove and tank at the inwall of bearing shell, offers the passage of perforation to the bearing shell outer wall on oil groove and tank respectively.
Oil groove described in the utility model is opened on bearing shell inwall one side two/one the cambered surface at least, and oil groove length is at least 1/2nd of bearing shell length, and tank is opened in bearing shell inwall opposite side.The horizontal V-type oil groove of oil groove for offering along bearing shell inwall cambered surface, the tip of V-type oil groove is towards the outer end of bearing shell.The vertical U type groove of described tank for offering along the bearing shell inwall.The wall thickness of bearing shell is 5～11% of a bearing shell internal diameter, and slenderness ratio is 1～1.4.The preferred MC nylon of described macromolecule engineering plastics.
The macromolecule engineering plastics have good wear resistance, high elastic modulus, low creeping property and better heat-resisting performance.Hardness ratio copper is low, and flexural strength and impact strength are but big than copper.Under the condition of light load low speed, can not add oiling agent, available water or oil are made oiling agent under high load and high-speed condition.The utility model with the macromolecule engineering plastic production; has self lubricity; wear-resisting property is good; wearing and tearing are very little in process of production, also can not burn out axle journal even the bearing shell heating occurs, can reduce or avoid the squeezer roll shaft to damage; the protection squeezing roller shaft neck; prolong the working life of roll shaft greatly, and maintenance cost obviously reduces, and manufacturing efficiency obviously improves.Can also alleviate equipment component weight in addition.On manufacture cost, for the press for extracting juice roller that use in general sugar refinery, each macromolecule engineering plastic bearing shell can be saved nearly 1,000 yuan RMB than bronze plain bearing.
MC nylon in the macromolecule engineering plastics claims monomer cast nylon again, and friction factor is 0.12～0.14, is 1/2 of copper.Proportion is less, is 1.4～1.2, has only 1/7～1/8 of cast copper, and journal wear is lower than ten thousand tons of sugarcanes of 0.05～0.06mm/.Compare with common nylon material, MC nylon is all obviously excellent more in the performance of intensity, rigidity, toughness, aspects such as low creep properties, wear resistance performance and chemical stability, and moisture absorption is littler than common nylon material.Particularly importantly MC nylon can keep good toughness and advantages of high bearing capacity in wider temperature range.The utility model of making of MC nylon is applicable to that sugar refinery has more superior performance when pressing roller, its good processability, anti-damage capability be strong, be easy to safeguard and price lower.
Because the ability to work of macromolecule engineering plastic bearing shell and the quality of life-span and lubrication circumstances have direct relation, for obtaining good oil film wedge and rotation oil clearance, with strengthen lubricating, reduce wear, life-saving, the utility model is chosen on the stressed less inwall of bearing shell and offers oil groove and tank, can when pressing the roller high load, apply oiling agent, reduce the wearing and tearing that bearing shell especially presses the roller roll shaft with high-speed running.Different with the greasy property of oil according to water, when selecting water to make oiling agent, oiling agent is entered by tank.When selecting oil to make oiling agent, oiling agent is entered by oil groove.Oil groove and tank adopt following layout and structure: oil groove is opened on bearing shell inwall one side two/one the cambered surface at least, and oil groove length is at least 1/2nd of bearing shell length, and tank is opened in bearing shell inwall opposite side.Oil groove is shaped as the horizontal V-type oil groove of offering along bearing shell inwall cambered surface, and the tip of V-type oil groove is towards the outer end of bearing shell.The vertical U type groove of tank for offering along the bearing shell inwall.Adopt above-mentioned layout and structure, high lubricating effect, the wearing and tearing of bearing shell especially being pressed the roller roll shaft obviously reduce.The wall thickness of bearing shell is 5～11% of a bearing shell internal diameter, slenderness ratio is 1～1.4, can avoid effectively that bearing shell and axle journal that may cause significantly heat up because the macromolecule engineering linear expansion coefficient of plastics is big, thermal conductivity is low, macromolecule engineering plastic bearing shell heat radiation is slow, the bearing shell volumetric expansion, reduce matching gap, causes the problem of poor circulation.
