Used device of passenger conveyor of the present invention, for example escalator 1 have a plurality of pedals 2, ring-type connect these pedals 2 pedal chain 3, be used to reel this pedal chain 3 and make its rotation drive sprocket 4 and driven sprocket 5, be used to drive drive sprocket 4 actuating device 6, hold above-mentioned member, cross over the main frame 7 of storey setting up and down, be vertically set on the railing 8 of its both sides along the moving direction of this main frame 7, and under the guiding of these railing 8 peripheries, drive the mobile moving hand-rail 9 that circulates by the power of actuating device 6.
Pedal 2 moves highly being configured to respectively between gangway, top cover plate 10A identical with the height of floor up and down and gangway, the bottom cover plate 10B circulation on main frame 7, moves in that the tilting zone of main frame 7 is stepped.
A pair of head sprocket 4 is separately positioned on the left and right sides by the axle drive shaft 11 of main frame 7 axle bearings, be provided with in this axle drive shaft 11 from actuating device 6 obtain the drive sprocket 12 of power and the transmission of power that will obtain from actuating device 6 to the handrail drive sprocket 13 of moving hand-rail 9.
Actuating device 6 has driving motor 16, to the output chain gear 14 of drive sprocket 12 outputting powers, the rotative speed of driving motor 16 is slowed down and it is delivered to the retarder 17 of output chain gear 14, drg 18 that the rotation of driving motor 16 is braked, pays retarder 17 with the rotating circular disk 19 of moment of inertia and the speed detector 20 that is used to detect escalator 1 speed, power chain 15 is wound between output chain gear 14 and the drive sprocket 12 with transferring power.
In addition, the actuating device 6 of first embodiment is provided with: be installed on the driving motor 16, with the rotation of first speed, the reducer input shaft 23 of top gear miniature gears 23B be installed on it; To be lower than the second speed rotation of first speed, the retarder tween drive shaft 22 with top gear miniature gears 23B ingear top gear big gear wheel 22A and bottom gear miniature gears 22B has been installed; To be lower than the third speed rotation of second speed, to have installed on it and bottom gear miniature gears 22B ingear bottom gear big gear wheel 21A and output chain gear 14, it is centered close to the reducer output shaft 21 on the center extended line of reducer input shaft 23; And the pony axle 24 by being rotated with the top gear big gear wheel 22A ingear second top gear miniature gears 24B, and reducer input shaft 23, retarder tween drive shaft 22 and pony axle 24 are vertically gone up and are provided with at grade.
In addition, reducer output shaft 21 is supported by bearing 26A that is assembled in reduction-gear housing 25 sides and the bearing 26B that is assembled on the reduction-gear housing 25 inner strengthening ribs, simultaneously, retarder tween drive shaft 22 is by the bearing 27A that is assembled in reduction-gear housing 25 sides, 27B supports, and pony axle 24 is fixed on the bearing 28A that is installed on reduction-gear housing 25 sides, on the 28B.In addition, driving motor 16 is fixed on the side of reduction-gear housing 25.
And, the tooth number Z 2 of the second top gear miniature gears is arranged to be less than the tooth number Z 1 of top gear miniature gears, the axle speed that is higher than reducer input shaft 23 with speed i.e. the 4th speed of first speed is rotated described pony axle 24, and is provided with described drg 18, rotating circular disk 19 and speed detector 20 on this pony axle 24 of high speed revolution.
And, because rotating circular disk 19 and sides retarder 17 opposite sides, compare with the side towards retarder 17 1 sides of output chain gear 14, its more close retarder 17 1 sides, so the radius sum of the radius of rotating circular disk 19 and output chain gear 14 equals or exceeds the distance between reducer output shaft 21 centers and pony axle 24 centers, thereby can strengthen the diameter of rotating circular disk 19.
In the first embodiment, because on the center extended line that is centered close to reducer input shaft 23 of reducer output shaft 21, and reducer input shaft 23, retarder tween drive shaft 22 and pony axle 24 vertically are provided with at grade, so can make the general width size LM of actuating device 6 become the gauge sum of diameter dimension and the reduction-gear housing 25 of bottom gear big gear wheel 21A, so can dwindle the width dimensions LM of actuating device 6.
In addition, because drg 18 required braking forces have the proportional characteristic of dwindling of rotating speed with the axle that drg 18 is installed, so, suppose when being set at the concerning of Z1=Z2 for example, when soon the axle speed of reducer input shaft 23 becomes identical speed with the axle speed setting of pony axle 24, it is T that escalator 1 is braked required braking force, then when setting for as the concerning of the Z1＞Z2 of present embodiment, escalator 1 is carried out the relation that the required braking force of glancing impact satisfies Z2/Z1 * T＜T, and the required littler masterpiece of braking force is a braking force in the time of therefore can setting than Z1=Z2.
And, aspect rotating circular disk 19, in order to ensure escalator 1 is carried out the required moment of inertia of safety arrestment, and the external diameter of rotating circular disk 19 is set for when identical, since the weight of rotating circular disk 19 have can according to square characteristic that the mode that is directly proportional alleviates of the rotating speed of rotating circular disk installation shaft, so, suppose when for example setting Z1=Z2 for, it is W that escalator 1 is carried out the required weight of safety arrestment, then when setting the concerning of Z1＞Z2 as the present embodiment for, weight required when escalator 1 is carried out safety arrestment satisfies (Z2/Z1)
2The relation of * W＜W, the required lighter weight of weight in the time of therefore the weight of rotating circular disk 19 can being set at than Z1=Z2.
According to first embodiment, because on the extended line at the center that is centered close to reducer input shaft 23 of reducer output shaft 21, and reducer input shaft 23, retarder tween drive shaft 22 and pony axle 24 vertically are provided with at grade, so can dwindle the width dimensions of actuating device 6, dwindle area is set, save the space, so can dwindle the length dimension LU of the Machine Room that this actuating device 6 is set.
In addition, by being provided with drg 18 and rotating circular disk 19 on the pony axle 24 that is higher than reducer input shaft 23 rotating speeds at rotating speed, so can realize the miniaturization of drg 18, therefore and can reduce the weight of rotating circular disk 19, can reduce the required cost of drg 18 and rotating circular disk 19.
Fig. 6 is the main portion cutaway view of actuating device second embodiment of expression device of passenger conveyor of the present invention.Among Fig. 6, adopt same-sign to represent with above-mentioned Fig. 1 part that extremely part shown in Figure 5 is identical.
The actuating device 6 of second embodiment shown in Figure 6 is compared with the actuating device 6 of first embodiment and has been carried out 90 ° displacement, and reducer input shaft 23, retarder tween drive shaft 22 and pony axle 24 along continuous straight runs settings are at grade.
According to second embodiment, if because the relation that the space is set of escalator 1, when the dimension D of Machine Room depth direction is restricted, be horizontally set on the Machine Room bottom surface side by the long side LH with actuating device 6, then short transverse becomes short brink, promptly becomes above-mentioned width dimensions LM, can dwindle the depth dimension D of Machine Room thus significantly, therefore, even be restricted, also can carry out the setting of escalator 1 at the Machine Room depth direction.
