Definitions

  • the invention relates to a handrail drive for escalators, moving walks or the like. Passenger conveyor according to the generic part of the first claim.
  • a handrail drive for escalators and the like is known.
  • a handrail drive wheel partially encompassed by the handrail and driven by a step sprocket and arranged between the two deflection wheels of the handrail, against which the handrail can be pressed by means of a belt.
  • the handrail drive wheel is connected in a known manner coaxially and non-rotatably to the step chain wheel.
  • the step chain engages the peripheral area of the step chain wheel that faces away from the pressure belt.
  • DE-C 35 26 905 relates to a drive for escalators, moving walks or the like, which is arranged in the deflection area and contains at least one electric motor with planetary gear as a central axis-like drive unit which is provided parallel to the axis of the step or pallet drive shaft and the handrail drive shaft.
  • the drive unit is thus placed between the driven shafts and / or immediately next to them.
  • Either a countershaft or a chain is necessary to drive both the handrail wheel and the step or pallet wheel, so that the driving force can be divided between the two areas.
  • a handrail drive would have to be used which is formed indirectly via the drive chains, for example by at least one additional chain wheel attached to the handrail wheel.
  • Such solutions are, however, to be regarded as complex, especially since the engagement of the respective drive chain is also problematic.
  • the object of the invention is to design a handrail drive that is relatively simple and that takes up very little space.
  • the handrail drive has a relatively short coaxial construction and can be easily provided in the area of the balustrade head without spatially obstructing other components, such as the stepped drive.
  • the first stage of the planetary gear is preferably helically toothed, while the following stages are designed with straight teeth. Because at least parts of the planetary gear are already provided within the spatial extension of the handrail wheel, the installation space can be reduced even further.
  • the construction is functionally optimal, whereby the gear and motor, preferably an electric motor, form a structural unit. As a result of the drive for the handrail acting directly on the handrail wheel, further diversions or drive elements in the region of the transport route are unnecessary.
  • FIGS. 1 and 2 show the handrail drive 1 according to the invention in different views, the following components being essentially recognizable here: the handrail wheel 2, the electric motor 3, the motor brake 4, the console 5 for supporting the handrail drive in the upper balustrade area, not shown here, for example an escalator.
  • FIG. 3 shows a cross section through the handrail drive 1.
  • the combination of the electric motor 3 and the planetary gear 6 is connected as a drive unit to the drive region 27 of the handrail wheel 2.
  • the planetary gear 6 has three stages 7, 8, 9, the first stage 7 being helically toothed and the adjoining stages 8 and 9 being provided with straight teeth.
  • Each stage 7, 8, 9 is formed from pinions 10, 11, 12 in planet carriers 13, 14, 15, planet gears 16, 17, 18 and a ring gear consisting of two individual wheels 19, 20.
  • the output shaft 21 of the electric motor 3 is toothed and meshes with the pinion 10 of the first stage 7.
  • the individual gear 19 cooperates with the first stage 7, while the individual gear 20 is axially longer and with the planet gears 17, 18 of those connected to it Levels 8 and 9 combs.
  • the single wheel 19 has a radially outward-pointing flange 28 to which the electric motor 3 is fastened by means of screws 22.
  • an axially extending sleeve-shaped projection 23 is provided, which axially engages over the individual wheel 20 and whose free end 24 engages in a circumferential groove 25 of the radial flange 28 to form a labyrinth seal.
  • a roller bearing 26 is located radially above the third stage 9 of the planetary gear 6 between the shoulder 23 and the individual wheel 20.
