Abstract
An elevator system includes a car and/or a counterweight connected to a belt having a plurality of ribs. The elevator system further has at least two deflecting elements over which the belt is guided and which each have a plurality of grooves. The grooves of at least one of the deflecting elements are configured with geometries that differ from the grooves of another of the deflecting elements. The belt has longitudinal ribs that cooperate with the grooves.
Claims9
An elevator system including a car and/or a counterweight, a belt supporting the car and/or the counterweight, a first deflecting element over which the belt is guided, and a second deflecting element over which the belt is guided, comprising:
- the belt includes a plurality of tension-bearing elements running in a longitudinal direction of the belt and a sheath in which the tension-bearing elements are embedded;
- the belt has a first side and a second side opposite the first side, wherein the belt is guided with the first side over both the first deflecting element and the second deflecting element;
- at least the first side of the belt has a plurality of ribs running in the longitudinal direction of the belt;
- each of the first and second deflecting elements has a plurality of grooves with which the ribs of the first side of the belt mesh;
- and
- wherein the grooves of the first deflecting element have a first geometry in cross-section, and the grooves of the second deflecting element have a second geometry in cross-section different from the first geometry, the cross-sections being transverse to the longitudinal direction of the belt when the ribs are meshed with the grooves.
