ELEVATOR DRIVE APPARATUS WITH VIBRATION ISOLATION MEANS

摘要

An elevator drive apparatus comprising a motor and reduction gear unit 5 resiliently mounted on a first support member 4 via vibration isolators 6, and a traction sheave 13 rotatably mounted on a second support member 10 via a bed member 11 and vibration isolators 12. An output shaft 7c of the reduction gear unit is connected to the sheave by an elastic coupling 15. The vibration isolators and the elastic coupling isolate vibrations generated by the engagement between the teeth of the reduction gears and by the pulsating rotation of the drive motor and reducing such vibrations from the sheave, which improves the ride comfort in the elevator cage on hoist cable 17.
