JP 2002-80178 A - Since the rotation axis of the driving sheave is thus inclined with respect to the rotation axis of the deflector sheave in the conventional elevator apparatus, it is necessary to attach the driving apparatus to the machine base at an incline. Thus, adjustment of the attachment angle takes time and trouble. Further, an angle at which the main ropes enter rope grooves of the driving sheave becomes large, and there is a fear that the lifetime of the main ropes will become short due to friction with the rope grooves.
- Further, the driving apparatus is disposed in an uppermost portion within the hoistway, and therefore it is necessary to extend a space within the hoistway upward for Gases where the driving apparatus is made larger, and the size of the hoistway becomes larger in the vertical direction.

Thecontrol panel 23 is disposed within a region in which thelanding door apparatus 11 and thecar door apparatus 10 are disposed, as seen in a vertical projection plane thereof. - With this type of elevator apparatus, the rotation axes of the driving
sheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21 are disposed extending parallel to each other, and therefore work for installing thedriving apparatus 15, thecar deflector sheave 20, and thecounterweight deflector sheave 21 can be performed easily. - Further, the angle at which the
main ropes 18 enter rope grooves of the drivingsheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21 can be made smaller. The lifetime of themain ropes 18 can thus be extended. That is, the rope grooves of the drivingsheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21 which correspond to themain ropes 18 can be disposed on one straight line, and the angle at which the ropes enter the rope grooves can be made substantially equal to 0°. - In addition, the
driving apparatus 15 is disposed in a position which is located lower than thecar deflector sheave 20 and thecounterweight deflector sheave 21 and where thedriving apparatus 15 does not overlap with theupper beam 6 in the vertical projection plane thereof. Accordingly, it is not necessary to extend a space within thehoistway 1 upward, even for cases where a largesize driving apparatus 15 is used, provided that the driving apparatus does not interfere with thecar frame 7 and thecage 8. The size in the vertical direction of thehoistway 1 can thus be made smaller.

driving apparatus 15 is disposed in a position at which a portion of the drivingapparatus 15 overlaps with thecar 4 in the vertical projection plane thereof, and therefore the cross sectional surface area of thehoistway 1 can be made smaller. - Further, the
driving apparatus 15 is disposed in a position at which a portion of thedriving apparatus 15 overlaps with thecar deflector sheave 21 and thecounterweight deflector sheave 21 in the vertical projection plane thereof. The cross sectional surface area of thehoistway 1 can therefore be made smaller. - In addition, the driving
apparatus 15 is attached to the lower portions of the machine bases 12, and the car deflector sheave and thecounterweight deflector sheave 21 are attached in the upper portions of the machine bases 12. The drivingapparatus 15 can therefore be disposed in a position that is located lower than thecar deflector sheave 20 and thecounterweight deflector sheave 21 by using common machine bases 12. - Still further, the
control panel 23 is disposed directly above the landinghall door apparatus 11 and thecar door apparatus 10, and therefore the space within thehoistway 1 can be utilized effectively. - It should be noted that, although the machine bases 12 are supported by the
structural beams 13 on the building side in the example described above, a structure may also be used in which the machine bases 12 are supported by, for example, at least either thecar guide rails 2 or the counterweight guide rails 3. In this case, the load burden on the building can be reduced. Conversely, for cases where the machine bases 12 are supported by thestructural beams 13, the load burden on theguide rails guide rails - Further, either a thin motor whose diameter dimension is larger than its axial dimension, or a large cylindrical motor whose axial dimension is larger than its radial dimension may be used for the
motor portion 16 of the drivingapparatus 15. - The diameter of the driving
sheave 17 may be set to a value that differs from at least the diameter of thecar deflector sheave 20 or thecar deflector sheave 21. Adjustment of the winding angle of themain ropes 18 to thedriver sheave 17 can thus be performed. - For example,

Adjustment of the angle at which themain ropes 18 are wound to the drivingsheave 17 can thus be performed by changing the relationship between the diameter of the drivingsheave 17 and the diameters of thecar deflector sheave 20 and thecounterweight deflector sheave 21. - Further, adjustment of the angle at which the
main ropes 18 are wound to the drivingsheave 17 can also be performed by changing the distances among the drivingsheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21. - In addition, the driving
sheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21 can be made smaller by setting a ratio D/d to a value equal to or less than 20, where D is the diameter of the drivingsheave 17, thecar deflector sheave 20, and thecounterweight deflector sheave 21, and d is the diameter of themain ropes 18. Saving of space in thehoistway 1 can also be achieved. - Still further, in order to make the sheaves smaller as described above, resin-covered ropes in which an outer layer covering made from a high friction resin material is provided in an outer peripheral portion thereof may also be used as the main ropes.
