Abstract
An arrangement for guiding belt-shaped ropes of an elevator includes a plurality of belt-shaped ropes; and a rope wheel deck including a frame mounted on a structure of an elevator, a plurality of rope wheels for guiding ropes of the elevator, and plurality of bearings, wherein the rope wheels are cambered and mounted coaxially on the frame via the bearings such that they are rotatable relative to the frame as well as relative to each other, wherein only one belt-shaped rope passes around each of said rope wheels of the rope wheel deck. An elevator implements the arrangement for guiding belt-shaped ropes of an elevator.

An arrangement for guiding belt-shaped ropes of an elevator comprising:
- a plurality of belt-shaped ropes;
- a rope wheel deck comprising a frame mounted on a structure of an elevator, a plurality of rope wheels for guiding ropes of the elevator, and a plurality of bearings, wherein the rope wheels are cambered and mounted coaxially on the frame via the bearings such that they are rotatable relative to the frame as well as relative to each other;
- and
- a hollow cylinder surrounding the central shaft, a wall of the hollow cylinder being radially between the rope wheels and the central shaft,
- wherein only one belt-shaped rope passes around each of said rope wheels of the rope wheel deck, and the plurality of bearings comprise a bearing which is radially between each of the rope wheels and the cylinder and supports each and every one of the rope wheels such that all of the rope wheels are rotatable relative to the hollow cylinder.
An elevator comprising:
- a hoistway;
- an elevator car and a counterweight vertically movable in the hoistway;
- a plurality of belt-shaped ropes interconnecting the elevator car and counterweight;
- and
- an arrangement for guiding the belt-shaped ropes, the arrangement comprising:
- a rope wheel deck comprising a frame mounted on a structure of an elevator, and a plurality of rope wheels for guiding the ropes of the elevator, and a plurality of bearings, the rope wheels being cambered and mounted coaxially on the frame via the bearings such that they are rotatable relative to the frame as well as relative to each other;
- and
- a hollow cylinder surrounding the central shaft, a wall of the hollow cylinder being radially between the rope wheels and the central shaft,
- wherein only one belt-shaped rope passes around each of said rope wheels of the rope wheel deck, and the plurality of bearings comprise a bearing which is radially between each of the rope wheels and the cylinder and supports each and every one of the rope wheels such that all of the rope wheels are rotatable relative to the hollow cylinder.
