Abstract
An illustrative example embodiment of an elevator governor includes a rotatable governor mechanism, a tension sheave, and a tension frame associated with the tension sheave. The tension frame has a mass configured to bias the tension frame and the tension sheave under an influence of gravity. A damper is configured to resist vertical movement of the tension frame relative to a fixed surface in a first condition and to allow vertical movement of the tension frame relative to the fixed surface in a second, different condition.
Claims10
An elevator governor, comprising:
- a rotatable governor mechanism;
- a tension sheave;
- a tension frame associated with the tension sheave, the tension frame having a mass configured to bias the tension frame and the tension sheave under an influence of gravity;
- and
- a damper configured to resist vertical movement of the tension frame relative to a fixed surface in a first condition, the damper being configured to allow vertical movement of the tension frame relative to the fixed surface in a second, different condition,
- wherein
- the damper includes a coupling configured to secure at least one portion of the damper to the tension frame, and
- the coupling allows for at least some lateral movement of the tension frame relative to the damper.
