Last rank side and following rank side in the truss 2 are provided with ladder sprocket wheel 8 and ladder sprocket wheel 9.A plurality of steps 3, the Conveyorized step chain of the annular of the both sides by being arranged at each step 3 connects, and this step chain is turned back after connecting ladder sprocket wheel 8,9, and moves circularly by being driven in truss 2 by the ladder sprocket wheel 8 of last rank side.
Fig. 2 (a) is the section-drawing around the sprocket wheel of escalator 1 shown in Figure 1.Among Fig. 2, S. A. 10 is supported by bearing 10a rotationally at the both ends of its axis direction.This bearing 10a is by on the beam material 2a that does not have graphic fixed parts and be installed in truss 2.
About ladder sprocket wheel 8 near the axis direction end of S. A. 10, be fixed on the S. A. 10 respectively.In the side of the ladder sprocket wheel 8 on paper right side, 8b is installed with the drive sprocket 8a that is driven by no graphic actuating device by liner (spacer).And,, engage the back, be used to prevent the ratchet 10c of S. A. 10 and the common anti-phase rotation of driving direction by the liner 8d fixed installation graphic ratchet of being and not being (ratchet) in the side of the drive sprocket 8a in paper left side.
Connect Conveyorized step chain 11 on these ladder sprocket wheels 8 with turning back.Mesh the step roller 4,5 of Conveyorized step chain 11 by the tooth of this ladder sprocket wheel 8, from ladder sprocket wheel 8 to Conveyorized step chain 11 transmission of drive force.In addition in figure for the purpose of simplifying the description, only at the Conveyorized step chain 11 of the upper illustration of ladder sprocket wheel 8.
Shown in the enlarged drawing of Fig. 2 (b), see that from section the central authorities of Conveyorized step chain 11 have the step roller 4 of front wheel side, the both sides of this step roller 4 are provided with inner links plate 12 and outer links plate 13.This inner links plate 12 is connected adjacent step roller 4 with outer links plate 13.Step roller 4, inner links plate 12 and outer links plate 13 are mutually pivotally connected by rotating shaft 13a, thus the Conveyorized step chain 11 of looping.As shown in the figure, Conveyorized step chain 11 has made up the step roller 4 as the front wheel side of the step 3 of the roller of central portion.Therefore, do not need step roller 4 roller that is used for step chain 11 in addition, help to reduce the narrow widthization of parts and truss.
This step roller 4 has: the 4a of bearing portion is entrenched on the S. A. 10a that is arranged at the step side end; Metal parts 4b is fixed on the outer peripheral face of the described bearing 4a of portion; Peripheral part is fixed in the periphery of described metal parts 4b.Have lubricant and roller between the inner ring of the 4a of bearing portion and the outer ring.Possess and seal so that the no graphic sealing unit that described lubricant is not spilt.
