Definitions

  • the invention relates to a device for guiding a belt continuum for escalators or moving walks consisting of steps or pallets, of chain links which are connected to the adjacent chain links by means of chain bolts, and of chain rollers held by the chain bolts, the chain rollers on a track of a support rail and on one Travel the track of a compensating rail and be deflected by a sprocket.
  • an escalator with a step-bearing step belt and chain wheels has become known.
  • the chain wheels arranged at each end of the escalator serve to deflect and drive the step belt.
  • the step belt consists of rollers connected by chain links, which are guided on support rails. When the step belt is deflected at the end of the escalator, the rollers are carried by the chain wheel from the entrance to the exit.
  • the support rails are arranged so that the rollers on the sprocket rotate by 180 °.
  • the path from the vertical central axis of the chain wheel to the support rail is bridged by a tangential guide arranged on the side of the chain wheel.
  • the tangential guide takes over the rollers from the support rail and guides the rollers in the tangential direction onto the sprocket circle.
  • the rollers leave the sprocket circle after a rotation of 180 ° in the tangential direction and are then guided from the tangential guide to the support rail.
  • the tangential guides do not eliminate the jerky movements and noise of the chain links that occur when the rollers engage the teeth of the chain wheel and when the rollers are detached from the chain wheel.
  • the jerking movements in the resonance range lead to longitudinal and transverse vibrations which are perceived by the passenger as unpleasant and which lead to a qualitative loss due to excessive wear of mechanical parts.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of guiding the belt continuum in such a way that the driving comfort perceived by the passenger is high, jerky movements and noises are avoided and the mechanical wear is kept low become.
  • Quiet running properties have an advantageous effect on the service life of the mechanical parts and cause less repair and maintenance work. It is also advantageous that smaller sprocket diameters and / or longer chain links are possible. Quiet running guarantees the passenger a fatigue-free stay on the means of transport. In addition, due to the shock, jerk and vibration-free stay on the escalator or on the moving walk, the passenger draws positive conclusions about the mechanical quality of the means of transport.
  • 1 denotes a chain wheel which serves to deflect and drive a belt continuum 2 of an escalator or moving walk.
  • 1 shows the entry of the belt continuum 2 onto the chain wheel 1.
  • the belt continuum 2 consists of steps or pallets (not shown) and of chain rollers 3, which are connected by means of chain links 4 and chain pins 5.
  • the chain rollers 3 run on a support rail 6 and on a side arranged on the chain wheel 1 Compensating rail 7.
  • Sprocket teeth 9 arranged on the circumference of the sprocket 1 form tooth gaps 10 in which the chain rollers 3 engage.
  • the axis of a tooth space 10 is designated 11 and is at right angles on a sprocket circle designated 12.
  • a tangent 13 to the sprocket circle 12 that runs parallel to a raceway 8 of the support rail 6 is at a tangent point 14 at right angles to the respective tooth gap axis 11.
  • the chain roller 3 engages with the sprocket 1 on the input side or leaves the sprocket 1 on the output side and then arrives on the output side arranged compensating rail 7.
  • the chain bolts 5 move at an angular velocity w on a wheel center circle 15 with a radius r and on the raceway 8 of the support rail 6 at the speed v.
  • the straight running track 8 of the support rail 6 merges into a curved track 16 of the compensating rail 7, which ends at the tangent point 14.
  • the track 8 of the support rail 6 lies at a certain distance h0 outside the tangent 13, so that the chain rollers 3 move on the track 16 of the compensating rail 7 in the forward direction and at right angles to the forward direction.
  • the compensating rail 7 It consists of a rail body 17 with the track 16 and a rail foot 18 on which bores 19 are arranged.
  • the compensation rail 7 is attached to the frame of the sprocket 1 by means of the holes 19 penetrating screws.
  • Fig. 7 shows schematically the sprocket and the band for the mathematical approach to deriving an optimal curve shape of the raceway 16 of the compensating rail 7.
  • the division of the band continuum 2 is with the variable l shown.
  • the variable l is the distance between two adjacent chain pins 5.
  • the instantaneous angle between the tangent point 14 'and the chain pin 5 on the wheel center circle 15 is shown by ⁇ .
  • Two adjacent chain bolts 5 lying on the wheel center circle 15 form an angle ⁇ m with the center point of the chain wheel 1.
  • the variables ⁇ 1 and ⁇ 2 represent the current angle of the chain link 4 with respect to the tangent 13 'to the wheel center circle 15.
  • the variables x2 and y describe the current path in the tangent direction or perpendicular to the tangent direction.
  • x 2nd l * cos ⁇ 1 + l * cos ⁇ 2nd - r * sin ⁇ [3]
  • y l * sin ⁇ 1 [4]
  • x ⁇ 2nd -f * ⁇ ⁇ * r
  • z is the number of teeth on the chain wheel 1.
  • the speed factor f can be determined using equation [4 '] and the initial and final integration constants.
  • the rotary speed w and the translatory speed v must be coupled by the speed factor f, which has the value 0.993587 for a sprocket 1 with 16 sprocket teeth, for example.
