The utility model provides a kind of polyurethane roller, comprise outer ring, wheel hub composition, the inner peripheral surface of wheel hub is fixed with bearing, meshes by regular concaveconvex structure between the inner peripheral surface of outer ring and the outer peripheral face of wheel hub, the cross-sectional plane of outer ring inner peripheral surface is internal tooth form, and the cross-sectional plane of wheel hub outer peripheral face is external tooth form.The utility model manufacture craft is simple, and cost is low, the yield rate height, and sound construction, the load-carrying capacity height, stability of rotation is good.
Description
Technical field
The utility model relates to a kind of roller of escalator, specifically is meant a kind of polyurethane roller.
Background technology
Escalator is generally used for the big occasion of flow of the people, and the requirement of its pair roller serviceability is very high, as requires the roller outer ring that better elasticity is arranged, and inner ring has better rigidity, and requires roller big, wear-resisting etc. from heavy and light, carrying.In production application, usually require that every roller must (for example front wheel be 200 kilograms under certain load, 130 kilograms of rear rollers), under 34 meters/minute linear velocity, move 50 hours continuously, any damage phenomenon does not appear, and the roller operation process require must be very steady, do not allow bigger beating.And whether ageing-resistant in order to determine roller, before the operation test, want first poach (95 ℃) 24 hours, parked again 24 hours, just test.
Each step of escalator is equipped with each 2 of front wheel and rear rollers.Front wheel of Shi Yonging and rear roller have a kind of to be to make of two kinds of polyurethane materials of different hardness, to adopt the annular concave-convex structure engages at outer peripheral face on its structure design in the market, and manufacture craft is injection outer ring earlier, injects wheel hub again.The problem that exists is: (1) annotates the outer ring earlier, annotates wheel hub again, is difficult to guarantee bearing, wheel hub and the outer ring three's of whole roller concentricity, and it is big to beat in the roller operational process, and traveling comfort is not enough.The adhesive surface of (2) two kinds of polyurethane materials is less, bond strength is not high, very difficult assurance adhesional energy between the two is by the life test of roller, promptly bear (130 kilograms of the trailing wheel load-bearing of certain load, the front-wheel load-bearing is 200 kilograms), under 34 meters/minute linear velocity continuously operation 2 very much clock wheel hub and cylindrical separation phenomenon do not appear, therefore existing this kind roller and preparation method thereof rate that manufactures a finished product is not high, and load-carrying capacity is not strong, still can not satisfy batch production requirements well.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and the polyurethane roller that a kind of manufacture craft is simple, yield rate is high, load-carrying capacity is strong is provided.
The purpose of this utility model is achieved through the following technical solutions: described a kind of polyurethane roller comprises outer ring, wheel hub composition, the inner peripheral surface of described wheel hub is fixed with bearing, mesh by regular concaveconvex structure between the inner peripheral surface of described outer ring and the outer peripheral face of wheel hub, the cross-sectional plane of described outer ring inner peripheral surface is internal tooth form, and the cross-sectional plane of wheel hub outer peripheral face is external tooth form.
Must realize the utility model for better, described outer ring outer peripheral face is provided with annular channel; The inner peripheral surface of described wheel hub and the outer peripheral face of outside race are fitted, and described wheel hub inner peripheral surface both sides are provided with flange, fit respectively in described flange and described outside race two sides; Described wheel hub inner peripheral surface can have cannelure by the outside race both sides; Described bearing outer peripheral face can have groove; Described wheel hub can be unitary solid structure or the structure that has reinforced rib.
The polyurethane material of shore hardness 88～95A is adopted in described outer ring, and described wheel hub adopts the polyurethane material of shore hardness 60～75D.
Described polyurethane material comprises thermoplastic polyurethane; Can add 10～30% filler in the described polyurethane material, described filler comprises nano-calcium carbonate or glass fibre.
In the utility model, earlier the injection wheel hub is injected the outer ring again, has guaranteed concentric between outer ring, wheel hub and the bearing three.The inner peripheral surface of outer ring and the outer peripheral face of wheel hub are meshing with each other by the structure of external tooth form, internal tooth form, increased the area of contact between wheel hub and the outer ring, simultaneously avoided stress concentration again, guaranteed that both adhere firmly, under high-mechanic and situation about working long hours, can not damage easily.The outer ring outer peripheral face has annular channel, can avoid the outer ring injection mo(u)lding after, the outstanding situation of burr appears at its external peripheral surface; In the roller use, also can change worn-down degree when judging the roller running by the depth of observing conduit.According to the load size of escalator, wheel hub can manufacture unitary solid or reinforcing rib structure.Add 10～30% filler nanometer calcium carbonate or glass fibre in the polyurethane material, can improve its intensity and rigidity.Putting into mould injection moulding wheel hub after the bearing sulfuration that scribbles adhesives, put into outer ring mould again and inject the outer ring annotating good wheel hub, can guarantee between wheel hub and the bearing, the bond strength between wheel hub and the outer ring, make the roller can be than working under the load greatly.If the bearing outer peripheral face adopts the structure of open channels, then during injection moulding because the polyurethane of fusing enters in the groove, wheel hub and bearing are closely chimeric, can prevent skidding, even can not need to add adhesives.When this polyurethane roller was used for outdoor occasion, described wheel hub inner peripheral surface can embed protective cover in the cannelure that has by the outside race both sides, play dustproof and waterproof, the effect that prolongs the service life of roller.
The utility model compared with prior art has following advantage and beneficial effect:
(1) polyurethane roller of the present utility model adopts injection wheel hub earlier, injects the technology of outer ring again, sound construction, and load-carrying capacity is good, has guaranteed the concentricity between bearing, wheel hub and the outer ring three, has reduced manufacturing procedure.
(2) polyurethane roller of the utility model making, its outer ring inner peripheral surface and wheel hub outer peripheral face have increased the area of contact between wheel hub and the outer ring greatly by the structure engages of internal tooth form, external tooth form, have avoided stress concentration again.
(3) polyurethane roller of the utility model making, its outer ring and wheel hub all are to adopt polyurethane material to make, in light weight, the polyurethane material of shore hardness 88～95A is adopted in the outer ring, and wheel hub adopts the polyurethane material of shore hardness 60～75D, forms close, compatibility is good, mutually bonding firmly, and not fragile, its load-carrying capacity can reach 130 kilograms-200 kilograms under high-mechanic and situation about working long hours.Simultaneously, add 10～30% filler nanometer calcium carbonate or glass fibre in the polyurethane material, improved the intensity and the rigidity of roller, help the smooth running of escalator.
(4) the utility model manufacture craft is simple, and cost is low, has marketing using value preferably.
