Abstract
The utility model provides an automatic staircase step chain with the advantages of high efficiency and long service suitable for heavy load conditions so as to overcome the defects of inflexible roller running and rotating as well as not good lubricating effect of the heavy load step chain in the prior art. The heavy-load step chain comprises an inner chain plate, an outer chain plate and a pin roll or a step pin roll; the inner chain plate and the outer chain plate are connected through the pin roll or the step pin roll; a sleeve is arranged at the periphery of the pin roll or the step pin roll; a sealing bearing served as a roller is arranged outside the sleeve; moreover, the sealing bearing and the sleeve are in interference fit. As a rolling bearing is adopted by the heavy-load step chain as a roller, the rolling friction between the roller and a chain wheel as well as a chain can be guaranteed; meanwhile, the friction resistance and noise can be reduced. In addition, the bearing capacity can be increased than that of a non-metal roller.
Description
Technical field
the utility model relates to a kind of step chains that is used for escalator, is specifically related to a kind of heavily loaded step chains that is applicable to severe duty.
Background technique
are present, and the escalator step chain of conventional design is made up of inner plate, outer plate, bearing pin, step bearing pin, sleeve, roller.Wherein roller mainly contains following two kinds of patterns:
1. metal roller are applicable to medium and heavily loaded occasion by the single cylindrical component that metal material processing forms.
2. nonmetal roller is formed with the non-metal elastomers that is positioned at the outside by being positioned at inner stuffing box bearing; Also can be in above-mentioned layer of metal or the nonmetallic material of increasing between the two; Be the composite members that comprises two kinds or above material, be applicable to underloading and medium load occasion.
Other part material of
step chains is a carbon steel, and lubricating between them carried out drop lubrication by the self-oil feeder that is arranged in the escalator usually, and lubricant medium is a lubricant oil.
have two major defects at present for the metal roller step chains of using in heavily loaded occasion.The first, roller inner and outer diameter difference is less, rotates dumbly during operation, has the phenomenon that produces sliding friction with chain guide, has increased surface friction drag, wearing and tearing and noise; The second, lubricating oil viscosity is less, and lubrication effect is bad under fully loaded transportation condition.
Summary of the invention
The technical problem that
the utility model will solve; Dumb, lubrication effect defect of bad is rotated in the roller operation that is to overcome step chains in the existing technology, and a kind of fully loaded transportation condition, high efficiency, long-life escalator step chain of being applicable to is provided.
In order to solve these problems of the prior art, the technological scheme that the utility model provides is:
a kind of heavily loaded step chains; Comprise inner plate, outer plate and bearing pin or step bearing pin; Connect through bearing pin or step bearing pin between described inner plate and the outer plate; Be provided with sleeve at described bearing pin or step bearing pin periphery, it is characterized in that: be outside equipped with stuffing box bearing at described sleeve as roller, and described stuffing box bearing and sleeve interference fit.
are further; On described bearing pin and/or step bearing pin, have oil guiding hole through its axle center; Lubricating cup is equipped with in an end central position at described bearing pin and/or step bearing pin, links to each other through attachment hole respectively between lubricating cup and the above-mentioned oil guiding hole.The space that lubricating grease is formed through plane on the above-mentioned oil guiding hole entering bearing pin and sleeve inner ring is lubricated through the rotation that relatively rotates bearing pin and sleeve between the slit between bearing pin and sleeve and bearing pin and sleeve.
are further, are to be opened on the through hole that passes through its axle center and vertical axes on said bearing pin or the step bearing pin at described oil guiding hole.The structure of oil guiding hole vertical axes can not reduce the mechanical strength of bearing pin or step bearing pin, and increases the quantity delivered of lubricant oil.
are further, in the both sides of described roller stuffing box bearing lining are housed respectively, and lining plays roller stuffing box bearing and chain effect at interval, prevents the wearing and tearing of roller stuffing box bearing.
are further, are provided with back-up ring in the outside of described outer plate, and said back-up ring is contained in the outer plate outside and snaps in bearing pin or the step bearing pin groove.
are further, and an end of said step bearing pin is equipped with roller.
are further, and said lubricating cup and roller are installed in the same side of chain.
are further, and said roller is made up of with the non-metal elastomers of being located at the outside the stuffing box bearing of inside.
are further, and described non-metal elastomers is a polyurethane.
are further, and described inner plate and outer plate are provided with slotted hole.These holes can reduce the chain deadweight, because these slotted holes are by the equal strength principle design, so can not reduce the specified Breaking load of chain.
are than solution of the prior art; The utility model advantage is: because heavily loaded step chains directly adopts rolling bearing as roller; Can guarantee the rolling friction between roller and sprocket wheel and chain guide; Reduce surface friction drag and noise, nonmetal relatively roller can increase bearing capacity; The oil storage space that plane on bearing pin and the step bearing pin and sleeve are formed makes and forms reliable lubricant film between bearing pin and sleeve, provides lubricated reliably.
