Abstract
The utility model discloses a polyurethane and metal composite material elastic diaphragm of a coupler, which is an approximately annular structure of which the center is provided with a round hole. The utility model comprises a surface layer, sclerites, steel rings and a filling layer, wherein both ends of the sclerite are provided with long waist-shaped metal thin sheets of through holes; at least two sclerites of which the holes are opposite are upwards and downwards parallel with each other to form sclerite groups; both ends of each group of sclerites are respectively coincident with holes of another group of sclerites and stacked with sheets of the group of sclerites to form a hinge-shaped round ring. The filling layer is a polyurethane layer arranged between two adjacent sclerites of the sclerite group. The steel rings are arranged on the upper and the lower surfaces of the sclerite group which is overlapped; the sizes and the positions of holes of the steel rings are in accordance to the sizes and the positions of sclerite holes. The surface layer is a polyurethane layer arranged outside the sclerites and the steel rings. The utility model has the advantages of low cost, small size, light weight, corrosion resistance, long service life, etc., and is particularly suitable for working conditions with large torque and high speed. Besides, the utility model can fully exert the composite advantages of polyurethane and metal.
Description
Technical field
The utility model relates to a kind of coupling flexible sheet, the coupling flexible sheet that specifically a kind of macromolecular material and metallic composite are made.
Background technique
Coupling is a kind of in the transmission connecting piece, along with the raising of industrial technology level in recent years, the requirement of coupling technology content is also improved greatly.Long-life, high-speed, high pulling torque, corrosion-resistant, low noise coupling become the product of market in urgent need.
The flexible sheet coupling is a kind of in the coupling, because diaphragm is formed by the sheet metal riveted joint.Under high pulling torque, high-speed working condition, using effect is better.But, not corrosion-resistant again because sheet metal is very thin, even in air, use, also, more can not in Korrosionsmedium, use usually because of the very fast damage of corrosion.So the material of the employed sheet metal of coupling flexible sheet has all made stainless steel now into.Like this, not only product cost improves, and stainless steel compares with the metallic elastic material, and mechanical mechanics property is lower.For guaranteeing driving torque, have to increase thickness or amplify external diameter.Make the size of coupling become big, weight increases, and rotary inertia strengthens.Increase energy consumption, also limited the raising of rotating speed.Moreover in some special Korrosionsmedium, stainless steel can not bear.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of cost is low, volume is little, in light weight, corrosion-resistant and long service life and adapt to the polyurethane and the metallic composite coupling flexible sheet of high pulling torque, high-speed operating mode, to overcome the above-mentioned defective that existing stainless steel flexible sheet exists.
The technological scheme of the utility model technical solution problem is as follows:
A kind of polyurethane and metallic composite coupling flexible sheet for the center is provided with the approximate circle ring structure of circular hole, is characterized in that, comprise top layer, osteocomma, steel loop and packed layer; Described osteocomma is the long waist type sheet metal that two ends are provided with through hole, be arranged in parallel up and down and the hole, hole is relative that at least two osteocommas constitute the osteocomma groups, the two ends of every group of osteocomma respectively with other one group of osteocomma, the coincidence of hole, hole, sheet intersect with sheet and stack, and form the hinge shape annulus; Described packed layer is the polyurethane layer that is arranged between adjacent two osteocommas of osteocomma group; Described steel loop is arranged on the upper and lower surface of overlapping back osteocomma group, and the size and the position in steel loop hole and osteocomma hole adapt; Described top layer is to be coated on osteocomma and the outer polyurethane layer of steel loop.
The quantity of described osteocomma group is even number.
The thickness of described every osteocomma is 0.20～2.00mm.
Compared with prior art, the utility model also has following advantage except that the advantage of having inherited coupling stainless steel flexible sheet:
1, be fit to high pulling torque, high-speed: because osteocomma can adopt the high elasticity metal, its mechanical mechanics property is better than the stainless steel osteocomma, is applicable to high pulling torque, high-speed working condition, under the situation of transmitting same moment of torsion, and smaller volume, weight saving.
2, the permission offset is bigger, the life-span is long: because the more stainless energy of deformation V of high elasticity metal value is big, the flexural fatigue performance is good, has improved the compensation performance of coupling.When coupling two flanges were installed, the angular error of permission can arrive 1 °, and the radially EE Error Excepted of shaft axis can arrive 0.5mm.Under same working condition, bending fatigue resistance can be good.
3, corrosion-resistant: polyurethane has good decay resistance, even in some special aggressive medium, also can change polyurethane formulations targetedly, guarantees to use for a long time.Utilize modern high technology, give full play to the advantage of polyurethane and metallic composite, protection high elasticity metal osteocomma is not corroded long service life.
4, low noise: because the high elasticity of polyurethane and excellent noise elimination absorbing performance make coupling turn round steadily, reduce noise.
5, save material, reduce cost: stainless steel coupling flexible sheet all is a circular shape, and material uses the rectangular area calculating of press the annulus external diameter.Compare with the utility model, because osteocomma is long waist type, sheet intersects to stack with sheet and is hinge type and then forms annulus.Under the situation that standard pitch circle equates, a slice is pressed the rectangular area that the annulus external diameter calculates, can cutting 8～10 length of a film waist type osteocommas.Under the situation that the intersection place of stacking is of uniform thickness, because about 20% material can also be saved in crack between sheet and the sheet.
