Abstract
A composite elevator belt includes at least one load carrier strand extending in a longitudinal direction, a core layer encasing the at least one load carrier strand, and a first plurality of teeth extending transversely across a top surface of the core layer. The first plurality of teeth includes a root portion associated with the core layer and a tip portion. The composite elevator belt further includes a first jacket layer extending in the longitudinal direction, at least the tip portion of the first plurality of teeth being associated with a bottom surface of the first jacket layer.
Claims18
A composite elevator belt comprising:
- at least one load carrier strand extending in a longitudinal direction;
- a core layer encasing the at least one load carrier strand;
- a first plurality of teeth extending transversely across a top surface of the core layer, the first plurality of teeth comprising a root portion associated with the core layer and a tip portion;
- and
- a first jacket layer extending in the longitudinal direction, at least the tip portion of the first plurality of teeth being associated with a bottom surface of the first jacket layer;
- wherein the tip portion is associated with the bottom surface of the first jacket layer such that the core layer and the first jacket layer define a transversely extending groove between adjacent teeth of the first plurality of teeth that is void of material.
An elevator system, comprising:
- an elevator shaft having a support frame;
- an elevator car movable along a vertical travel path defined by the elevator shaft;
- a motor arrangement comprising at least one drive sheave rotatable via the motor arrangement;
- at least one elevator sheave connected to one of the elevator car and the support frame;
- and
- at least one composite elevator belt in frictional tractive engagement with the drive sheave of the motor arrangement and the at least one elevator sheave, the at least one composite elevator belt comprising:
- at least one load carrier strand extending in a longitudinal direction;
- a core layer encasing the at least one load carrier strand;
- a first plurality of teeth extending transversely across a top surface of the core layer, the first plurality of teeth comprising a root portion associated with the core layer and a tip portion;
- and
- a first jacket layer extending in the longitudinal direction, at least the tip portion of the first plurality of teeth being associated with a bottom surface of the first jacket layer;
- wherein the tip portion of the first plurality of teeth of the at least one composite elevator belt is associated with the bottom surface of the first jacket layer such that the core layer and the first jacket layer define a transversely extending groove between adjacent teeth of the first plurality of teeth that is void of material.
