Problems solved by technology

[0003] Such drive pulleys with plastic inserts are complex and expensive
The main problem, however, is that such driving pulleys are practically no longer possible with a diameter of less than 100 mm, since the fastening of the insert is no longer sufficiently stable with such small overall dimensions

Embodiment Construction

[0022] figure 1 A schematic view of an elevator installation 1 according to a first embodiment of the invention is shown. The elevator installation 1 has a drive pulley 2 for driving a plurality of traction means 3 - 3E. In addition, in figure 1 shows a situation in which the counterweight 4 is suspended on the one side and the elevator car 5 on the other side from the drive pulley 2 by means of the traction means 3-3E. Here, the tractive force F1 produced by the counterweight 4 and the tractive force F2 produced by the elevator car 5 acting on the drive pulley 2 in the stationary state are shown, which act on the side 6 or 7 of the drive pulley 2 to The traction mechanism 3 wraps around the area of ​​the drive pulley 2 . The drive pulley 2 is connected to the drive unit and is positioned, for example, in the upper region of the shaft of the elevator installation 1 .

[0023] exist figure 1 A situation is shown in , in which the force F1 of the counterweight 4 is greater ...

Abstract

The traction sheave (2) has a traction surface which forms the structures, which contribute traction effect between the traction surface and a traction mechanism (3) in a peripheral direction. The structures run at the traction surface in a direction, which deviates from the peripheral direction. An independent claim is also included for an elevator system with an elevator car.

Description

technical field [0001] The invention relates to a drive pulley for driving a traction mechanism of an elevator installation and to an elevator installation having such a drive pulley. In particular, the invention relates to an elevator installation in which such a drive pulley drives a traction mechanism designed as a belt with an elastomer jacket, in particular as a wedge-ribbed belt. Background technique [0002] GB1121220 discloses a pulling rope pulley for cooperating with elevator ropes. To the pulley rope pulley, an insert made of plastic is fastened to its edge, which comprises a pull surface for cooperating with the elevator rope or for driving the elevator rope. The pulling surface forms a semicircular rope groove for receiving round elevator ropes, wherein the rope groove is equipped with transverse grooves oriented perpendicularly to its longitudinal axis. The purpose of this transverse groove is to ensure the pulling capacity between the drive pulley and the el...
