The input shaft 11. Both ends of each of the intermediate shaft 13 and the output shaft 16 are pivotally supported by the gear housing 8a via bearings 18. 19 is the output shaft 16
The chain device 20ζ connects the pulley 16a provided in the upper sprocket device 3 with the large pulley 3a of the upper sprocket device 3, and is an electromagnetic brake provided on one side of the input shaft 11.

[Problem that the invention seeks to solve]

The conventional passenger conveyor device is configured as described above and includes a speed reducer 8. 'IEJ! Mainly electric 8110! When the J machine 21 is configured and the electric motor 10 is energized, the chain device 19. Upper sprocket device 3. Ws
A treadle 6 is operated via the plate chain 5. Furthermore, the reduction gear 818 is constituted by a parallel shaft gear device 9 with good transmission efficiency, thereby reducing driving force. However, reducer 8 and electric motor 1
0 are connected by a shaft coupling 10b, there is a problem in that it requires complicated turning work to align the axes and install them on the bed 7. There is a problem in that it requires processing, which increases production costs. Furthermore, since both of the above are arranged horizontally, the space occupied in the cramped machine room 2 becomes large, and although not shown, the machine room 2 is also provided with a control room for the passenger conveyor, etc. Therefore, there is a problem that there is a lack of space for maintenance work, which limits maintenance work. Furthermore, in the reduction gear 818 consisting of the parallel shaft m wheel device 9, when transmitting the power of the electric power to the output shaft 6, the driving force of the input shaft 11 is transmitted through the gear 14 and the gear 15 provided on the intermediate shaft 13. The transmission is transmitted to the gear 17 of the output shaft 16, which is provided in multiple stages with a large number of gears, and requires a 6g bearing 18 as a bearing for each shaft, which reduces the efficiency of the reducer due to frictional load. There was a point.

This invention solves the above-mentioned problems, and aims to provide a passenger conveyor drive device that can be easily installed in a narrow machine room and that improves the efficiency of the reducer. .

[Means for solving problems]

The passenger conveyor drive device of the present invention includes one binion in which a reduction gear made of a parallel shaft gear device is fixed to an input shaft;
It consists of a single gear fixed to an output shaft meshing with the pinion, an electric motor mounted on top of the reducer, and a gear installed between the electric motor and the input shaft of the reducer. It is equipped with a wrap-around transmission device.

[For production]

Since the passenger conveyor drive device of the present invention has the above-described configuration, the reduction gearing device is composed of a single-stage parallel shaft gear device that can transmit power from an electric motor to a gear on an output shaft via a pinion fixed to an input shaft. Since it is a machine, the transmission efficiency of the reducer can be improved, and the reducer can be made smaller.
In addition, since the electric motor is placed on top of the reduction gear, the space occupied by the drive machine in the machine room 81 is reduced, and space for maintenance work can be secured.

[Embodiment J] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, the same reference numerals as in FIGS. 5 to 8 indicate the same or corresponding parts, and 23ζ is a frame-shaped stand, and 23a has a lower part 81.
Side plates fixed to 2 floors of room 14, 23b are side plates 23 on both sides
an upper plate fastened to the upper end of a; 8 a reduction gear consisting of a parallel shaft gear device 9 disposed between the side plates 23a and having a side surface of a gear housing 8a fixed to the side plate 23a; and 10 mounted on the upper plate 23b. The electric motor 10 is fixed at a fixed position, and 10a is the shaft of this electric motor 10. 24 is a winding transmission device, and the shaft 10a
Small pulley 25 fixed to the input shaft 11 of the reducer 818
It is composed of a large pulley 26 fixed to the main pulley 26, and a belt 27 wound between the small pulley 25 and the large pulley 26. Further, as shown in FIG.
one binion 12 fixed to and this binion 12
The input shaft 11 and the output shaft 16 are arranged in mesh with each other and one gear 17 is fixed to the output shaft 16.
It is pivoted via 8.

In one embodiment of the present invention configured as described above, the drive device for the passenger conveyor includes an electric motor [10], a winding transmission device 24, a speed reducer 8. Via the chain arrangement 19 the upper sprocket arrangement 3 is driven. Since the electric fi 10 is disposed above the speed reducer 8s8 via the stand 23, the space occupied in the machine room 2 is reduced, a space for maintenance work can be secured, and maintenance and inspection can be easily performed. In addition, the electric motor 1 is
Since both the gear 0 and the reducer 8 are rotationally connected, the tolerance for the accuracy of the mounting position of both of them is increased, and the assembly can be easily manufactured and assembled at a low cost. In addition, in this embodiment, a reducer 8 consisting of a parallel shaft gear device 9 is constructed of a 1@ pinion 12 fixed to an input shaft 11, and a gear 17 of an output shaft 16 meshing with this pinion 12. By reducing the number of gears in the reducer 8 and using bearings 18 only on the input shaft 11 and output shaft 16, the frictional load is reduced compared to the conventional method using intermediate shafts. This has the effect of improving the efficiency of the reducer.

〔Effect of the invention〕

As explained above, the drive device for the passenger conveyor according to the present invention includes an F! Since the machine and electric VIJ machine are rotatably connected, the space occupied in the machine room can be reduced, maintenance work in the machine room can be easily performed, manufacturing and installation are easy, and the reduction gear is efficient. Drive bagging of passenger conveyor can be realized.
