Embodiment Construction

[0015] Such as figure 1 As shown, a novel pulley for an elevator traction machine of the present invention includes a pulley body 2, and a pulley outer ring 4 is set on the pulley body 2, and the pulley outer ring 4 is provided with an entrance 6 for the traction rope 5 to penetrate and For the outlet 8 that the traction rope passes through, when the slideway on the pulley body 2 wears and causes the traction rope 5 to sway, the entrance 6 and the outlet 8 can control the traction rope within a limited range, thereby preventing it from carrying out comparison. large deflection.

[0016] In addition, in order to prevent the inlet 6 and the outlet 8 from being enlarged due to wear, a wear-resistant layer (not shown) is provided on the inner wall of the inlet 6 and the outlet 8, and the wear-resistant layer can be a rubber layer or a ceramic layer.

[0017] In order to make the present invention have a better anti-deflection effect, the lengths of the inlet 6 and the outlet 8 ar...

Abstract

The invention discloses a novel pulley for an elevator dragger. The novel pulley for the elevator dragger comprises a pulley body (2); the novel pulley for the elevator dragger is characterized in that a pulley outer-ring (4) is sleeved on the pulley body (2) and is provided with an inlet (6) for permitting a dragging rope to enter inside and an outlet (8) for permitting the dragging rope to exit outside. The novel pulley for the elevator dragger is simple in structure and the deflection of the dragging rope can be prevented.

Description

technical field [0001] The invention relates to a pulley, in particular to a novel pulley for an elevator traction machine. Background technique [0002] Elevators, especially vertical elevators, rely on the tension of multiple traction ropes to operate vertically in the air. Once the traction ropes break during operation, it may cause casualties and equipment damage. Once the traction rope deflects, it will cause the car to shake, which indirectly reduces the passenger comfort of the elevator. Therefore, it is very important to prevent the deflection of the traction rope during elevator operation. The pendulum often starts from the pulley in contact with it. After the pulley is worn for a long time, the slideway on it will become wider, which will cause the traction rope to sway on the slideway, and finally cause the car to swing. [0003] To sum up, existing pulleys on the market have the defect and problem that they cannot prevent the traction rope from swaying. Conten...
