Definitions

  • the invention relates to escalators with a rotating step conveyor for the transport of people between different levels and moving walks with a rotating plate conveyor for horizontal passenger transport, consisting essentially of a supporting structure with side railings (balustrades), a step or plate conveyor, guides in the supporting structure for this Conveyor train, two revolving handrail belts and one drive station.
  • the drive station contains two sprockets for driving the long link chains of the conveyor train, which are driven by a geared motor via roller sprockets and drive chains flanged to them. These conveyor chain sprockets are connected by a common hollow shaft.
  • Rolling bearings are pressed into the center of each conveyor chain sprocket and sit with their inner ring on a non-rotating central axis, the ends of which are fixed in axle carriers screwed to the supporting structure.
  • the assembly described here is in the following as Sprocket assembly ".
  • the rolling bearings lubricated for life are through Operating forces are highly stressed and often more humid and corrosive Environment exposed. You usually have to in the course of Life span of the passenger conveyor replaced several times become. In the known versions of such escalators and moving walks require replacement of the rolling bearings time-consuming additional manipulations such as ripping of the conveyor train and drive chains, lifting the Sprocket assembly from the supporting structure as well as the Reassembly of the dismantled and separated components. An additional problem is that the moving walk during is not accessible as stairs at this time.
  • the purpose of the present invention is to significantly simplify the rolling bearing replacement on the sprocket assembly of escalators and moving walks, in particular in that the conveyor train no longer has to be separated and the sprocket assembly no longer has to be lifted out of the supporting structure.
  • This is achieved in that the support structure on both sides of the drive station has auxiliary supports on which the sprocket assembly on both sides by means of releasable connections, such as. B. screw connections with spacers or plug connections can be fixed rigidly. This makes it possible to remove the central axle beams screwed to the supporting structure, which in the normal state cover the access to the roller bearings in the conveyor chain sprockets, and to replace the roller bearings according to a method according to the invention.
  • the rolling bearing replacement process proceeds as follows: First, the long link chains of the conveyor chain near the drive station are attached to the support structure by means of conventional chain blocking devices in such a way that the drive station is relieved of the chain hoist. This is followed by the fixation of the sprocket assembly to the support structure described above and the removal of the central axle beam.
  • the central axis of the sprocket assembly is pulled axially to the left with the help of a spindle pull-out device attached to the left conveyor chain sprocket so that the axle end pushes the inner ring of the right-hand side to be removed Roller bearing leaves.
  • a commercially available bearing pulling device which is supported on the front side of the central axis locked by the spindle pulling device, the roller bearing is now pulled out of the outer bearing seat in the sprocket by its now accessible inner ring.
  • a new roller bearing is pressed into the bore of the chain wheel using a spindle press-in device.
  • the central axis is then pulled so far to the right that this inner ring is now exposed and the bearing can be removed and replaced as above. Finally, the central axis is pushed into the normal position, the central axle supports are reassembled and the fixing of the chain wheel assembly to the auxiliary supports of the supporting structure and the chain locking devices are removed. The system is now ready for operation again.
  • Fig. 1 shows schematically the essential elements of a passenger transport device according to the invention, i.e. specifically an escalator 1, with the support structure 2, the side railings (balustrades) 3, the step conveyor train 4, the circumferential handrail belts 5 and the chain wheel assembly 6 of the drive station.
  • the invention relates to features in the area of the sprocket assembly, which is practically identical for escalators and horizontal moving walks.
  • Fig. 2 you can see in the side view of the truss structure 2 of the escalator with the central axle beams 7 fastened to it by means of screw connections, which support the fixed central axis 8 of the chain wheel assembly 6.
  • auxiliary supports 9, 10 are attached to the supporting structure, which serve to fix the chain wheel assembly described below.
  • 3 shows the left-hand part of the (symmetrical) sprocket assembly 6. This essentially consists of two conveyor chain sprockets 16 which are connected to one another by a hollow shaft 14 and which are supported on the central axis 8 via the roller bearings 15 pressed into these sprockets.
  • FIG. 4 shows a cross section through the sprocket assembly after removal of the central axle support 7 and reveals the spindle pull-out device 19 which is screwed onto the conveyor chain sprocket 16.1 with screws 20 for pulling out the central axis 8 laterally.
  • 5 shows a next phase of the bearing exchange, in which the central axis 8 is pulled so far to the left by means of the spindle puller 19 that the inner ring of the roller bearing 15.2 pressed into the right-hand conveyor chain sprocket 16.2 is accessible to a bearing puller.
  • two groups of setscrews 21 arranged in a star shape are visible in the casing of the hollow shaft 14 and, according to claim 4, form an auxiliary centering for the central axis.
