Abstract
The utility model relates to a polyurethane trundle. The polyurethane trundle comprises an inner trundle, an outer trundle, reinforcing ribs, a shaft hole and a polyurethane layer, wherein, the polyurethane layer is coated outside the outer trundle. The polyurethane trundle disclosed by the utility model avoids the defects that the conventional trundle made of rubber or plastic rubber material cannot resist wear, cannot firmly adhere to a metal skeleton, is easy to age, and the like, combines the rigidity of a metal product with the elasticity and the wear resistance of polyurethane material, is designed through applying an engineering science, can reduces the gravity center of a vehicle, runs steadily, reduces the running resistance, firmly adheres to the metal skeleton, and has the advantages of high elastic body bearing ability, high tear strength, wear resistance, oil resistance and high torsion modulus.
Description
Technical field
The utility model relates to a kind of transportation device, relates in particular to a kind ofly to make caster wheel by polyurethane material.
Background technology
In the transportation transmission process, carry out more easily in order to make transportation, often can use conveying arrangements such as waggon, flat truck.These transportation transmission devices generally adopt the rubber of different shape or the wheel of plastic cement material because rubber and plastic cement material quality are soft, in the transportation transmission process, can alleviate contact with ground and take place jolt, shake.But there is not wear-resisting, poor with the metallic framework adhesion, easy defective such as aging in the wheel of rubber and plastic cement material, and the old wheel of regular replacing worn-down of having to causes a large amount of consumption of material and the increase of cost.
The utility model content
The utility model relates to a kind of polyurethane castor, and the polyurethane foreign steamer is wrapped in outside the metal steel ring, has avoided the wheel of original rubber or plastic cement material not wear-resisting,, easily defective such as aging poor with the metallic framework adhesion.
The utility model polyurethane castor, concrete, comprise inside and outside two concentric circless wheel, be connected by disc-shaped structure between inside and outside two circle wheels; Wherein, the interior central authorities of taking turns are provided with axis hole, and described castor is made of metal, and foreign steamer coats one deck layer of polyurethane outward.
Above-mentioned polyurethane castor wherein, has reinforced rib on the described disc-shaped structure.
Above-mentioned polyurethane castor, wherein, reinforced rib is the center, points to the cylindrical wheel by interior circle wheel and be radial and evenly arrange with the castor center of circle.
Above-mentioned polyurethane castor, wherein, described reinforced rib has 5.
Above-mentioned polyurethane castor, wherein, the thickness of described inside and outside two castors is greater than the thickness of described reinforced rib.
Above-mentioned polyurethane castor, wherein, the material of described castor is iron, copper, nickel or its alloy.
The beneficial effects of the utility model are:
The utility model polyurethane castor elastic body load-carrying capacity is big, peel strength height, wear-resistance and oil-resistance, plurality of advantages such as modulus of torsion height, the turnover rate of minimizing castor, cost-cutting.
Description of drawings
Fig. 1 is the structural representation of the utility model polyurethane castor.
The specific embodiment
Following according to Fig. 1, embodiment of the present utility model is described:
As shown in Figure 1, the utility model provides a kind of polyurethane castor, comprises polyurethane castor 1, interior wheel 2, foreign steamer 3, reinforced rib 4, axis hole 5, layer of polyurethane 6, collar plate shape structure 7.
One axis hole 5 is arranged in the middle of the wheel 2 in described, two described axis holes 5 are respectively passed at transmission shaft two ends of hand barrow, flat truck or other rickshaws, connect two polyurethane castors 1, when the people carries out described hand barrow or flat truck etc. it is moved ahead, traveling process is steady, safety.
Described layer of polyurethane 6 is coated on the outside of foreign steamer 3, removes other parts of the polyurethane castor 1 outside the layer of polyurethane 6, makes by iron, copper, nickel or its alloy.
Described polyurethane castor combines the elasticity and the resistance to abrasion of the rigidity and the polyurethane material of metalwork, and through the engineering science design, reduces vehicle's center of gravity, operates steadily, and reduces running resistance.
More than specific embodiment of the utility model is described in detail, but it is as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of being done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
Claims (6)
1. a polyurethane castor comprises inside and outside two concentric circless wheel, is connected by disc-shaped structure between inside and outside two circle wheels; Wherein, the interior central authorities of taking turns are provided with axis hole, it is characterized in that, described castor is made of metal, and foreign steamer coats one deck layer of polyurethane outward.
2. castor according to claim 1 is characterized in that, has reinforced rib on the described disc-shaped structure.
