Embodiment Construction

[0041] Figure 1 is a schematic diagram of the structure of an elevator. The elevator is preferably an elevator without a machine room, in which the drive machine 6 is placed in the elevator shaft, although the invention is also suitable for elevators with a machine room. The walking situation of elevator hoisting rope 3 is as follows: one end of each rope is fixed on the anchor seat 13 in the upper shaft shaft top that is positioned at the top of counterweight 2 paths, and counterweight then moves along counterweight guide rail 11. From the anchorage the ropes run downwards and around diverting pulleys 9 which hang the counterweight, which are rotatably mounted on the counterweight 2 and from there the ropes 3 run upwards to the traction ropes of the driving machine 6 Wheel 7 walks around the traction sheave along each rope groove on the sheave. From the traction sheave 7, the ropes 3 then run downwards to the elevator car 1 moving along the car guide rail 10, where the eleva...

Abstract

A counterweight and an elevator car are suspended on a set of hoisting ropes. The elevator comprises one or more rope pulleys provided with rope grooves, one of said pulleys being a traction sheave driven by a drive machine and moving the set of hoisting ropes. At least one of the rope pulleys has against the hoisting rope a coating adhesively bonded to the rope pulley and containing the rope grooves, said coating having an elasticity that is greater in the edge portions of the rope groove than at the bottom of the rope groove. In a preferred solution, the traction sheave is a rope pulley like this.

Description

technical field [0001] The invention relates to an elevator and to an elevator traction sheave. Background technique [0002] Typical traction sheave elevators are based on a solution in which steel wire ropes, used as hoisting ropes and as suspension ropes, are moved by means of metal traction sheaves, often made of cast iron, driven by the elevator drive machine. Movement of the hoisting ropes causes movement of the counterweight and the elevator car suspended thereon. The traction force from the traction sheave to the hoisting rope, as well as the braking force applied by means of the traction sheave, is transmitted via friction between the traction sheave and the rope. [0003] The coefficient of friction between the steel wire ropes used in elevators and the metal traction sheave is often insufficient by itself to maintain the required grip between the traction sheave and the hoisting ropes under normal circumstances during elevator motion. Friction and the force tran...
