構造上の弱点が生じるという問題があった。In the above prior art, since the drive shaft and the flange of the split coupling portion are separate fitting systems, there is a problem in reliability due to loose fitting, and the number of parts increases. Due to the size increase, the manufacturing cost of the fitting portion was also high. Further, there is a problem in strength that a combined moment due to a bending moment and a torsional moment which exerts the largest force on the center of the shaft affects the split coupling portion of the drive shaft. Further, when trying to reduce the width of the entire passenger conveyor, there is a problem that a structural weakness such as a notch is generated in the frame (conveyor body frame) itself.

フランジを有し、ここでボルト等により接合することに
より、分割結合部の接合強度が向上する。[Action] to bias the bisected coupling portion a drive shaft from the center,
By dividing with drive kinematic sprocket side, the effect of largest acting bending moment and torsional moment becomes small with respect to division coupling unit and correspondingly strength of the division coupling unit correspondence to the shaft center. In particular, the drive sprocket
The chain of the step stretches the chain of the step sprocket
If you reverse the direction of the tension,
The chain tensions cancel each other and split
The influence on the joint can be eliminated. Moreover, the center
On the more anti-drive sprocket side, there is no split joint
Because it is a coaxial drive, the strength correspondence to the step sprocket
improves. Further, each of the divided drive shafts has a flange integral with the drive shaft, and is joined here by bolts or the like, so that the joining strength of the divided joint portions is improved.

することが可能となる。Since the bearings at the left and right shaft ends of the drive shaft are supported at intervals above and below the upper side of the body frame, fixing means such as bolts and nuts are provided within the interval. The position of the fixing means can be determined irrespective of a structure such as a vertical side portion of the main body frame. That is, if a bearing is placed directly on this upper side,
Since the fixing means and the vertical side part interfere with each other, in order to avoid this interference, the vertical side part has to be moved in a direction to enlarge the entire width of the passenger conveyor. By providing an interval between the main frame and the main frame, the degree of freedom of the fixed position of the bearing is increased, and the width of the entire conveyor can be reduced.

An escalator is constituted by the main body frame 10 and the balustrade 11, which are the entire strength holding body, in addition to the escalator 9.

るほか、ボルト１２によって一体的に結合されている。Here, the drive shaft 2 is closer to the drive sprocket 5 than its center (the relationship L 1 <L 2 with respect to the interval L).
Is divided into the driving shafts 2A and 2B, and further divided into the driving shafts 2A and 2B.
2B has integral flanges 2a and 2b, respectively. Both flanges 2a and 2b are fitted at the spigot 2c portion and are integrally connected by bolts 12.

た支持台１４にボルト１５で固設されている。The bearings 8 and 9 for supporting both left and right shaft ends of the drive shaft 2 are formed by combining three members of an upper side portion 10a, a vertical side portion 10b, and a lower side portion 10c (illustration of H-section steel). , And is fixedly mounted on a support base 14 spaced apart by h above the upper side portion 10a of the main body frame 10 having both sides connected by a lower side material 13.
【００１６】この間隔ｈがない場合には、ボルト１５を

ことになる。なお、図２の図示ではボルト１５を支持台
１４に直接ねじ込む構造としたが、この間隔ｈ内にナッ
トを収納することも可能である。If the distance h does not exist, if the bolt 15 is provided directly above the vertical side portion 10b, the bolt 15 and the vertical side portion 10b interfere with each other and cannot be screwed. Needs to be moved inward or outward of the bolt 15, resulting in an increase in the overall width Wb. Although the bolt 15 is directly screwed into the support base 14 in the illustration of FIG. 2, the nut can be accommodated within the interval h.

Since it is configured to be connectable and separable by a and 2b, it is easy to disassemble and reassemble from the main body frame 10. Bearing 8,
The positional relationship between 9 and the body frame 10 is also effective in reducing the overall width Wb, and the bearing can be fixed directly above the vertical side portion 10b, which is structurally advantageous.
