Abstract
An air gap adjusting apparatus for a cylindrical linear motor of an elevator includes a cylindrical upper plate having an internally threaded portion at an inner edge thereof and fixedly mounted on the upper portion of the rotor, a plurality of adjusting units pivotably mounted on the plate member, for adjusting an air gap between an inner surface of the rotor and the outer surface of the stator, and an inverted cone-shaped hollow tapered guide member having a threaded lower portion engaging the plate member and displacing the plurality of adjusting units for thereby adjusting an air gap between an inner surface of the rotor and the outer surface of the stator.
Claims6
An air gap adjusting apparatus for a cylindrical linear motor of an elevator having a cylindrical rotor having a longitudinal bore hole therethrough and a stator slidable within the bore hole, with a predetermined air gap between an inner surface of the rotor and an outer surface of the stator, comprising:
- a cylindrical upper plate member each having an internally threaded portion at an inner edge thereof fixedly mounted on an upper portion of the rotor;
- a plurality of adjusting units, pivotably mounted atop the plate member, for adjusting an air gap between an inner surface of the rotor and the outer surface of the stator;
- and
- an inverted frusco-conical-shaped hollow tapered guide member having an externally threaded lower portion by which it may be screwed into the internal thread of the plate member for adjusting the plurality of adjusting units.
