Abstract
A synthetic fiber rope having load-bearing aramide fiber strands laid together in parallel in concentric layers of strands and an intersheath with sheath surfaces adapted to the external contours of the adjacent layers of strands. By positively bonding the inner and outer layers of strands a higher torsional rigidity is achieved as well as a rope structure of the stranded rope which is less susceptible to twisting. Furthermore, the elastic intersheath between the layers of stands serves to protect the strands against abrasion and assists in transmitting torque within the rope over a large area.
Claims7
A synthetic fiber rope comprising:
- at least an inner layer and an outer layer of load-bearing synthetic fiber strands laid together, said layers being concentric and radially separated from one another forming an interlayer space, and a tubular shaped intersheath positioned in said interlayer space between said layers and enveloping said inner layer, said intersheath being elastically deformable and having a plurality of grooves formed therein, each one of said grooves being contoured to receive an associated one of said fiber strands of an adjacent one of said layers.
An elevator installation comprising:
- an elevator car;
- a traction means being one of a traction sheave and a rope drum;
- and
- a synthetic fiber rope in friction contact with said traction means and supporting said elevator car, said rope having at least an inner layer and an outer layer of load-bearing synthetic fiber strands laid together, said layers being concentric and radially separated from one another forming an interlayer space, and a tubular shaped intersheath positioned in said interlayer space between said layers and enveloping said inner layer, said intersheath being elastically deformable and having a plurality of grooves formed therein, each one of said grooves being contoured to receive an associated one of said fiber strands of an adjacent one of said layers.
A synthetic fiber rope comprising:
- an inner layer of load-bearing synthetic fiber strands laid together;
- an outer layer of load-bearing synthetic fiber strands laid together, said outer layer being concentric and radially separated from one another to form an interlayer space;
- and
- a tubular-shaped intersheath positioned in said interlayer space between said layers and enveloping said inner layer, said intersheath having a plurality of grooves formed therein, each one of said grooves being contoured to receive an associated one of said fiber strands of an adjacent one of said inner and outer layers, and said intersheath being comprised of an elastically deformable material providing a frictional resistance between said intersheath and said inner and outer layers substantially preventing relative movement therebetween.
