に比較して小形であり。As an elevator drive device, the reducer is energized by an electric motor and fixed to the output shaft of the reducer! Some models are equipped with a drive mesh wheel that rotates with
In some cases, the cat and counterweight 9 are raised and lowered by the main rope. In this case, there was a problem in that vibrations caused by the meshing of the gears of the reducer were transmitted to the car via the main rope, causing discomfort to passengers inside the car. Also, assume that the reducer is composed of parallel shaft gears such as helical gears *'i
An elevator has been proposed in which the f-motor is an AC motor and the motor is fully variable voltage variable frequency controlled (hereinafter referred to as VVVF control). In such an elevator, the power loss of the speed reducer is small due to the parallel shaft gears, resulting in an energy saving effect, and the AC motor is smaller than the DC motor.

歯車の減速機と。Since there are no brushes in a DC motor, it has the advantage of being robust, inexpensive, and easy to maintain. However, parallel shaft gears have large meshing vibrations, and in VVVF control of an AC motor, ripple vibrations occur due to current distortion generated during modulation in the inverter section, which is motivated by AC. For this reason, it is a parallel shaft gear reducer.

ｙｇＡｍ網車を枢着して。That is, the drive network wheel (13) is equipped with vibration-proof rubber 0 on a second support 01 that is different from the first support (4) that supported the drive machine (5).
It is pivotally connected to the base I supported via 2, and is rotationally connected to the output shaft (7C) of the drive machine (5) via an elastic transmission member αS'. Therefore, the vibration caused by the meshing of the gears of the reduction mechanism (7a) of the reduction gear (7) and the pulsating vibration in the rotational direction caused by the VVVF control of the AC motor (8) are damped by the elastic transmission body θeK, and the drive network 0:l vibrations are reduced. Also, the speed reduction mechanism (7a
), the vertical vibration of the AC motor (8) is suppressed by the anti-vibration comb (
6) Vibration is damped by H and the vibration of the drive network wheel is reduced. Therefore, it occurs in the drive machine (5) and the main rope (17+
Vibration transmitted to 0 seconds is reduced, and a comfortable force 1 is obtained. Output 11
It is obvious that the same effect can be obtained even if pulleys are provided on each of the pulleys 1 (7C) and an elastic transmission body made of an elastic strip such as a V-belt wrapped around these pulleys is used. Also. In the embodiment of Fig. 1-'i3, the drive network wheel (13
Since the deflection wheel θe is pivoted to the same base 9,
Since no horizontal load is applied to the vibration isolating rubber H, a simple vibration isolating structure can be achieved, and it can be manufactured at low cost. -i', the drive machine (5) is vibration-isolated from the vibration-isolating comb (6) K, and the drive net car (one groove is vibration-isolated by the anti-vibration rubber a force against the building in which the hoistway (1) is installed). Because of this,
As explained above, this invention does not transmit the vibrations of the driving machine (5) and the driving network vehicle (l) to the living rooms of the building, causing no vibrations or noise, and does not damage the living environment. The drive machine, which mainly consists of a speed reducer, is mounted on a support provided in the machine room of Nire-Mita, and the support provided in the Mayu machine room is provided with at least a vibration-proof arrangement for the drive machine. Pivotally attach the ygAm net wheel to the base.

回転連結したものである。これによって駆動機に生じる
振動が弾性伝動体により防振され。The shaft of the drive network wheel and the output shaft of the drive machine are rotationally connected by an elastic transmission body. As a result, vibrations generated in the drive machine are damped by the elastic transmission body.

As a result, vibrations transmitted to the elevator car are reduced, and an elevator drive system is realized that allows the elevator car to be operated with good quality.
