Abstract
The utility model relates to a kind of escalator roller, comprise roller core, roller inner ring, roller outer ring, it is characterized in that: roller core is arranged in roller inner ring endoporus, roller outer ring sleeve is contained on the outer ring of roller inner ring, the both sides, outer ring of roller inner ring are protruding side ring, in the annular groove that on the outer ring that roller outer ring is nested in roller inner ring, two protruding side rings are formed.Roller inner ring is Maranyl, and roller outer ring is TPUE, and when the utility model has the advantages that the end face of roller and carrier bar rub, the smooth resistance of nylon is less, is not easy card wheel, and nylon shrinkage percentage is little, and product end surface is beated less.Wheel is when assembling, and TPU not easily damages, and scratches, weighs wounded, and the wheel life-span improves.The monolateral stressing conditions of wheel makes moderate progress, and bearing life extends.
Description
Technical field
The utility model relates to a kind of roller, particularly a kind of escalator roller, and the utility model is also applied to elevator, moving sidewalk and airdrome luggage conveyer etc.
Background technology
At present along with economic development, increasing public arena arranges automatic escalator, as on airport, Railway station, subway station and market, automatic escalator is convenient to use, dark liking by operator.Because automatic escalator to roll cycle rotation with chain type, therefore need to use a large amount of rollers for relying on the rotatable parts of automatic escalator, the general passenger flow volume of occasion used due to automatic escalator is large, therefore be generally continuous rotation, as ensureing that the roller of automatic escalator safe handling assume responsibility for very important effect.Current roller is made up of plastics injection moulding, in it, the nylon plastic(s) of taking turns as high-abrasive material is made, skin is TPU plastics, TPU plastics are TPUE, there is very strong high tension, high tension, obdurability and ageing-resistant characteristic, a kind of environment-friendly materials of maturation, be enclosed within outside interior wheel and made roller, TPU plastics have exposing of a circle in side, but because TPU plastic shrink rate is large, therefore carrier bar that is easy and escalator produces large frictional resistance, easy card roller, and shrinkage percentage greatly also will cause carrier bar to beat increasing, the TPU plastics of side open are easily damaged when assembling, scratch and weigh wounded, roller can be made to reduce service life, and in the running of escalator, easy generation roller monolateral stressed, make the axial force of roller excessive, damage the bearing be arranged on roller, therefore urgently existing escalator roller structure is improved, design novel escalator roller.
Summary of the invention
The purpose of this utility model solves the problems referred to above in prior art existing for escalator roller, provides a kind of escalator roller of novelty.The utility model designs a kind of escalator roller, comprise roller core, roller inner ring, roller outer ring, it is characterized in that: roller core is arranged in roller inner ring endoporus, roller outer ring sleeve is contained on the outer ring of roller inner ring, the both sides, outer ring of roller inner ring are protruding side ring, in the annular groove that on the outer ring that roller outer ring is nested in roller inner ring, two protruding side rings are formed.Roller inner ring is Maranyl, and roller outer ring is TPUE, roller core be bearing or for slip liner or for roller inner ring medial surface on add layer.When the utility model has the advantages that the end face of roller and carrier bar rub, the smooth resistance of nylon is less, is not easy card wheel, and nylon shrinkage percentage is little, and product end surface is beated less.Wheel is when assembling, and TPU not easily damages, and scratches, weighs wounded, and the wheel life-span improves.The monolateral stressing conditions of wheel makes moderate progress, and bearing life extends.
Accompanying drawing explanation
Accompanying drawing 1 is the constructional drawing of prior art.
Accompanying drawing 2 is constructional drawing of the present utility model.
Detailed description of the invention
A kind of escalator roller in figure, comprise roller core 1, roller inner ring 2, roller outer ring 3, it is characterized in that: roller core is arranged in roller inner ring endoporus, roller outer ring sleeve is contained on the outer ring of roller inner ring, the both sides, outer ring of roller inner ring are protruding side ring 4, in the annular groove 5 that on the outer ring that roller outer ring is nested in roller inner ring, two protruding side rings are formed.Roller inner ring is Maranyl, and roller outer ring is TPUE, roller core be bearing or for slip liner or for roller inner ring medial surface on add layer.
Because roller end face outside of the present utility model is Maranyl, and the smooth resistance of Maranyl is little, the roller core of roller is bearing or for slip liner or for the medial surface of roller inner ring adds layer, therefore when the end face of roller and the carrier bar of escalator rub, is not easy card roller.And the shrinkage percentage of Maranyl is little, the face runout of roller is less.Roller is when assembling, and TPU, because be embedded in annular groove, not easily damages, and scratches, weighs wounded, and the life-span of roller improves.The monolateral stressing conditions of roller makes moderate progress, if roller core is bearing, also can extend the life-span of bearing.
The utility model also comprises the roller in the technical field being applied to moving sidewalk, elevator and airdrome luggage conveyer, and all concrete technical characteristics meet the roller described in the utility model claim, also belong to protection domain of the present utility model.
