Abstract
The utility model relates to a polyurethane roller which is composed of an outer ring and a wheel hub, wherein a shaft bearing is fixed on the inner peripheral surface of the wheel hub, the inner peripheral surface of the outer ring and the outer peripheral surface of the wheel hub are mutually engaged through a concave-convex structure, the outer ring is made of polyurethane material with the Shore hardness ranging from 90 to 95 A and the wheel hub is made of polyurethane material with the Shore hardness ranging from 60 to 75 A. The utility model has the advantages of simple manufacturing technique, low cost, light self weight of the produced roller, firm structure and good carrying capacity.
Description
Technical field
The utility model relates to escalator roller technical field, 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 300 kilograms under certain load, 200 kilograms of rear rollers), under 30 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.In addition in order to determine that can roller in long-term work under the load, also must be by the life test of clock very much of (the same) 2 under the fixed load, and jerk value also limits within the specific limits.
At present each step of escalator is equipped with each 2 of front wheel and rear rollers, and the outer ring of roller is usually with the manufacturing of injection government rubber, shore hardness 90～95A, and the resistance to abrasion of outer ring, load-carrying capacity can both meet the demands.The problem that exists is: the forging blank of the wheel hub use high-quality steel of (1) front wheel after heat treatment car system forms, and every wheel hub weighs and restrains 200 more, from great, and complex process, cost of manufacture height; (2) wheel hub of rear roller die casting aluminium structure, though weight gentlier, manufacturing cost is still higher, and the process for making contaminated environment.Also have a kind of roller on the market now, its wheel hub is plastic skeleton (for example nylon etc.), and the outer ring is a polyurethane, good from heavy and light, resistance to abrasion, but load-carrying capacity is not strong, because two kinds of materials of this kind roller are formed not close, compatibility is relatively poor, and is bonding not firm mutually, throws off soon during use.If be used for escalator, the performance requriements of the above-mentioned escalator roller of out of reach then.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provides a kind of wheel hub good from heavy and light, load-carrying capacity, and manufacture craft is simple, the polyurethane roller that cost is low.
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 ball bearing of main shaft, it is characterized in that: mesh by concaveconvex structure between the inner peripheral surface of described outer ring and the outer peripheral face of wheel hub, the polyurethane material of shore hardness 90～95A is adopted in described outer ring, and described wheel hub adopts the polyurethane material of shore hardness 60～75D.
Must realize the utility model for better, the central protrusion of described outer ring inner peripheral surface, both sides are provided with shoulder, and its cross-sectional plane is " protruding " shape, and the cross-sectional plane of described wheel hub outer peripheral face is " recessed " shape, and is corresponding with described outer ring inner peripheral surface shape; Described outer ring outer peripheral face is provided with annular channel; Described wheel hub inner peripheral surface both sides are provided with flange, and described flange and the upper and lower end face of described bearing are fitted respectively, and described bearing outer peripheral face has groove, and the inner peripheral surface of described wheel hub and the outer peripheral face of bearing are fitted; Described wheel hub is unitary solid structure or the structure that has reinforced rib.
Described polyurethane material comprises thermoplastic polyurethane.
In the utility model, the inner peripheral surface of outer ring and the outer peripheral face of wheel hub mesh by concaveconvex structure, have increased the area of contact between outer ring and the wheel hub, have avoided stress concentration simultaneously again, guarantee that both adhere firmly, under high-mechanic and situation about working long hours, can not damage easily.Simultaneously, middle part, outer ring wall thickness, wheel hub middle part respective wall is thin, when having avoided wheel hub injection moulding, does not freely produce the possibility of pore because of the heavy wall exhaust.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 situation 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.Bearing that scribbles adhesives and outer ring are put into mould, and the injection moulding wheel hub can guarantee between wheel hub and the bearing, the bond strength between wheel hub and the outer ring, and roller can worked under big load.As adopt bearing outer peripheral face open channels, then during injection moulding because the polyurethane of fusing enters in the groove, wheel hub and bearing are closely chimeric, prevent skidding, even can not need to add adhesives.
The utility model compared with prior art has following advantage and beneficial effect:
(1) polyurethane roller of the utility model making, its outer ring and wheel hub all are to adopt polyurethane material to make, and the wheel hub of steel, aluminium matter from heavy and light, helps the operation of escalator relatively.
(2) sound construction, load-carrying capacity is good, the polyurethane roller that the utility model is made, the inner peripheral surface of its outer ring and the outer peripheral face of wheel hub mesh by concaveconvex structure, increased the area of contact between outer ring and the wheel hub, avoided stress concentration again, simultaneously, the polyurethane material of shore hardness 90～95A 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, under high-mechanic and situation about working long hours and can not damage easily, its load-carrying capacity can reach 100～200 kilograms/only.
(3) the utility model manufacture craft is simple, and cost is low, has marketing using value preferably.
