Abstract
A sleeve step chain with a spiral oil storage tank belongs to the technical field of step chain transmission machinery for escalators. The sleeve step chain with the spiral oil storage tank comprises a roller assembly, an external chain board and an internal chain board. The surface of an inner round hole of a sleeve is provided with the spiral oil storage tank; a pin shaft passes through the inner round hole of the sleeve; and the pin shaft and the inner round hole are matched with each other rotatably. The resistance lubricating oil in the spiral oil storage tank greatly improves the lubricating effect between the pin shaft and the sleeve; the problem of difficult preservation of the lubricating oil in the traditional lubricating structure is solved; the sleeve step chain with the spiral oil storage tank can realize overall lubrication during the running process of the escalator, and achieve the effects of lowering noise and reducing the abrasion during the relative operation of the sleeve and the pin shaft; and the oil dirt, dust and particles attached on the surfaces of the pin shaft and the sleeve are discharged into grooves, thus improving the operation smoothness of the escalator and riding comfort.
Description
Technical field
The utility model relates to a kind of sleeve step chains that has the helix oil cistern, and it belongs to escalator step chains gearing technical field.
Background technology
At present, the step chains sleeve interior surface that escalator is used does not have groove, and bearing pin belongs to the plane with sleeve and contacts relatively, infiltrates the running that realizes bearing pin and sleeve by lubricating oil.Its frame mode has problems in actual applications: 1, bearing pin and sleeve gap retain dust easily and produce grease, roll the formation particle through running, its grease and particle are attached to bearing pin and sleeve surface, can't from the slit, discharge, produce friction between bearing pin and sleeve, when causing the staircase operation vibrations take place and produce noise; 2, step chains sleeve lubricating oil is not easy to retain, and causes the phenomenon that produces wearing and tearing or get rusty when bearing pin is relative with sleeve to be moved, thereby causes the decline in the service life of sleeve, increases and uses and maintenance cost.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the utility model provides a kind of sleeve step chains that has the helix oil cistern.This sleeve step chains should be provided with oil cistern on the interior circular hole surface of its sleeve, and the lubricating status when strengthening with the bearing pin normal-running fit reduces wearing and tearing, increases the service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sleeve step chains that has the helix oil cistern, it comprises roller assembly, pin link plate and the inner plate that is fitted together by roller, antifriction-bearing box, sleeve and bearing pin.The interior circular hole surface of described sleeve is provided with the helix oil cistern, and described bearing pin passes from the interior circular hole of sleeve, and is mutually normal-running fit.
Described helix oil cistern adopts circular arc as the oil cistern structure.
The store oil groove width a=1.0～2.0mm of described helix oil cistern, store oil groove depth b=0.5～1.0mm.
The beneficial effects of the utility model are: this sleeve step chains that has the helix oil cistern comprises roller assembly, pin link plate and inner plate.The interior circular hole surface of sleeve is provided with the helix oil cistern, and bearing pin passes from the interior circular hole of sleeve, and is mutually normal-running fit.Resistance lubricating oil in the helix oil cistern has greatly improved the lubricant effect between bearing pin and the sleeve; Improved the difficult problem of preserving of lubricating oil in the conventional lubrication structure; Can be lubricated comprehensively in the elevator operation process, reach the abrasive effect that reduces when moving relatively between noise, minimizing sleeve and the bearing pin; The grease, dust, the particle that are attached to bearing pin and sleeve surface are entered in the groove, thereby improve elevator running stability and ride comfort sense.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of constructional drawing that has the sleeve step chains of helix oil cistern.
Fig. 2 is an A-A cutaway view among Fig. 1.
Fig. 3 is a B enlarged drawing among the figure.
Fig. 4 is a sleeve spiral oil cistern constructional drawing.
Among the figure: 1, roller, 2, antifriction-bearing box, 3, sleeve, 4, bearing pin, 4a, spring cotter, 4b, pin-and-hole, 5, the helix oil cistern, 5a, circular arc, 6, pin link plate, 7, inner plate.
The specific embodiment
Fig. 1 shows a kind of constructional drawing that has the sleeve step chains of helix oil cistern.Among the figure, earlier inner plate 7 is enclosed within the two ends of roller assembly sleeve 3, again pin link plate 6 is enclosed within the two ends of roller assembly bearing pin 4, then spring cotter 4a is inserted among the pin-and-hole 4b of bearing pin 4 ends.According to said method the sleeve step chains is lengthened to the length of requirement.
Fig. 2 shows the structure cutaway view of roller assembly.Among the figure, the inner ring of an antifriction-bearing box 2 tightly is enclosed within the midway location of sleeve 3 external cylindrical surfaces, and outer ring and roller 1 tighten together, and graphic antifriction-bearing box 2 has adopted radial ball bearing.On sleeve 3 inner cylinder faces, be provided with helix oil cistern 5, in helix oil cistern 5, fill up lubricating grease after, again bearing pin 4 is inserted in the sleeves 3, bearing pin 4 is a bearing fit with sleeve 3.
Fig. 3,4 shows the helix oil cistern in the sleeve.Article one, open helix oil cistern 5 extends to the other end from an end of sleeve 3, and adopts circular arc 5a as the oil cistern structure.Aborning, as long as choose form cutter, just can very on sleeve 3 inner cylinder faces, process helix oil cistern 5 easily.The store oil groove width a=1.0mm of illustrative helicon shape oil cistern 5, store oil groove depth b=0.5mm.
