Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • Chains with long links have a higher specific strength, so a better ratio of strength to weight and are also less expensive and less maintenance after less chain links attack.
  • This solution also offers a certain flexibility the change in the direction of movement so that peaks in the speed change something can be buffered. on the other hand become such chain rollers, especially if they are as internal Chain rollers are formed, sometimes quite strong loaded, so that they are comparatively wear-intensive.
  • Escalators and moving walks can be significantly different Stressful situations exist. While an empty one Escalator in up-down operation already different Load conditions on the two deflection wheels for the drive chains this applies all the more to loaded escalators. Especially with increased escalator lengths and heights, such as, for example used for subway stations are driven to exert enormous forces on the escalator during the ascent, which are also transferred accordingly from the drive chain and must be supported by the running rails.
  • the invention is therefore based on the object of an escalator or a moving walk according to the preamble of claim 1 create the demand for improved drive comfort with the demands for a heavy-duty drive combines.
  • chain sprockets means that the working point, So also the running height of the steps, not more than a given dimension differs from the nominal running height, so that, for example, the teeth of the comb plate are not excluded Intervention. Having the escalator in this condition is heavily burdened anyway and therefore regularly alone emits an increased noise level from the drive train, it is not critical that the additional support of the chain sprockets the running noise is significantly higher than when idling the escalator or moving walk.
  • the chain sprockets in the area of the sprockets or chain deflection wheels are mainly used. You can do this the chain idler wheels have U-shaped teeth on average. The support sheets or tooth bases of the teeth then only reach under the chain sprockets so that the treads of the chain rollers be spared there.
  • an escalator 10 is shown, namely in the part relevant to the invention.
  • the escalator has one Escalator level 12, which is stored in a conventional manner is.
  • a drag roller 14 of the stage which is not relevant here runs on a secondary track 16.
  • the escalator step 12 is guided and driven by a journal 18 on which a chain roller 20 is rotatably mounted.
  • the chain roller 20 runs in a track 22 and is at the same time inside a drive chain 24 for the escalator.
  • roller bearing 34 here a ball bearing, plugged on, which supports the chain roller 20.
  • This construction is commonly referred to as an internal drive Chain roller designated.
  • the chain roller also has a tread surface 36 has that is somewhat more elastic and for example made of rubber consists. The tread covering springs a little under load on, but reduces the running noise.
  • chain rollers 38 and 40 provide the entire cylindrical Area each between the ball bearing 34 and the two chain links Fill 28 and center the ball bearing 34 at the same time.
  • the running rail has 22 has a substantially U-shaped construction in the running area.
  • This solution has the advantage that the tread material 36 Do not dodge sideways under heavy loads can, so that there is a spring characteristic with a slope.
  • a sprocket 42 is cut out in the upper region shown, namely in association with a transition curve 44.
  • the transition arc 44 is used for improvement in a manner known per se the entry of the drive chain to the sprocket 42. It has a horizontal section and a curved one Section 46, the reduction in a conventional manner of the polygon effect.
  • the transition curve 44 is again in the lower area of FIG. 2 shown in top view.
  • the transition arc 44 is in this embodiment divided in two. It stretches as better 3 can be seen in this way, one laterally central section 48 of the sprocket, which is also the same height both the sprocket and the transition arch the tread surface 36 of the chain roller 20 can wear. This will make a smooth transition achieved.
  • the sprocket 42 essentially is formed in three parts.
  • the teeth 50 and 52 are on the outside trained, while the central area has another set of teeth 54 has.
  • the teeth 50 and 52 each have a tooth base 56 and 58, while the toothing 54 has a tooth base 60, which, on the other hand, is radially inward.
  • the radial distance between the tooth bases 56 and 58 on the one hand and 60 on the other hand is slightly less than the distance between the surface of the Tread surface 36 and the surface of the chain sprockets 38th and 40.
  • the drive chain lies - and therefore also the chain rollers - only on the tooth base 54. If the Load increases, the tread covering 36 deflects somewhat, and the chain sprockets 38 and 40 lie on the tooth bases 55 and 58. This measure ensures that at low load a smooth and comfortable realization of the Chain drive is ensured. Because of the soft pad vibrations are dampened and the polygon effect is further reduced.
  • the chain sprockets 40 only come in when the load is high System with tooth bases 56 and 58. In this load condition the pad is quite stiff, so the tread coverings 36 not or not significantly further indented and therefore cannot be destroyed quickly.
  • chain division can be Extend to 135 mm without sacrificing comfort arises. This contributes significantly to the cost reduction.
  • This track 22 leads to an even further increased spring comfort, although the tread covering 36 is pressed in more under load.
  • FIGS. 7 to 12 Other embodiments can be seen from FIGS. 7 to 12. In all figures, the same or corresponding parts the same reference numerals are used. An essential difference between the two embodiments between FIGS. 1 to 3 or 4 to 6 on the one hand and the other figures in the design of the sprocket 42 and the transition arch 44. This will be explained with reference to FIG. 8.
  • the transition arch 46 has the same side view Design like the transition curve according to FIG. 2 or 5.
  • the horizontal section 68 of the transition arch is not divided into three, but has a width that is slightly larger than that Width of a chain roller 20 is. In this respect is horizontal Section 68 of the transition arch from its tread 70 essentially conventionally trained. Points at its bottom However, he has arcuate recesses 72 on his Outsides. These recesses serve to create appropriate areas of the sprocket 42 to record, for which reference to Fig. 9 is.
  • the transition arch 46 runs in the tongue in the curved region 74, which in the illustrated embodiment is half the width of the transition curve in section 68.
  • the tongue 74 continues the recesses 72.
  • their tread 70 is at the same level as shoulders 76 and 78 of the chain wheel.
  • the chain wheel according to FIG. 9 has an on average U-shaped structure.
  • the teeth 50 and 52 extend on both sides of a recess 80.
  • the width of the recess 80 corresponds to the width of the chain roller 20, inclusive a certain side game.
  • teeth 50 and 52 have tooth bases 56 and 58, which carry the chain idlers 38 and 40.
  • the embodiment is the distance between the Shoulders 76 and 78 and the tooth bases 56 and 58 on the one hand chosen that the chain rollers 20 when deflecting the chain over the sprockets 44 are practically not loaded. hereby The chain roller 20 adopts the deflection effect over the curved one Section 46 of transition arch 44, but the chain idlers lie on the sprockets and can there accordingly be heavily burdened.
