In FIG. 4, (a) shows the vibration transmission characteristic by the support part of the structure shown in FIG. 2, and (b) shows the vibration transmission characteristic by the support part of the structure shown in FIG. 3. In other words, as is clear from FIG. 4, the vibration transmission characteristics by the support part in the configuration shown in FIG. 2 and the vibration transmission characteristics by the support part in the configuration in FIG. The magnitude relationship between the amount of vibration transmitted by the support part in the configuration shown in the figure and the amount of vibration transmitted by the support part in the configuration shown in FIG.
2) It changes depending on the frequency of the vibration transmitted. Usually, the frequency of the vibrations generated by the hoist (1) and transmitted to the rope (2) is proportional to the speed of the elevator. for example,
The vibration of the elevator car due to the torque ripple generated by the hoisting machine (1) is controlled by the configuration shown in Fig. 3 just before the start (that is, when the frequency of the torque ripple is extremely small), as shown in the "solenoid control" shown in the lower part of Fig. 4. The transfer characteristic of the support part is lower than that of the support part of the configuration of FIG. Therefore, at this time, the solenoid (23) is turned on, and the elevator car frame (
I support 5). Next, as the speed increases, the solenoid (23) is switched from on to off at a point in time when the vibration transmission characteristics of the support section are reversed. This allows the second
The support part has the configuration shown in the figure, and the transmission characteristic of the support part at this time is lower than the transmission characteristic of the support part when the solenoid (23) is turned on. In this way, the solenoid (23
) is controlled on/off and always constitutes a support portion with low transfer characteristics. That is, the elevator car frame (5) is supported by the characteristic curve in which the small flames shown in the figure are connected.
