Abstract
The utility model discloses a pulley for an elevator dragger. The pulley comprises a pulley body (2), wherein at least one slideway (4) contacting with allocation pieces is arranged on the pulley body (2). The pulley for the elevator dragger is characterized in that a plurality of balls are arranged on the circumference of the slideway (4). The pulley for the elevator dragger is simple in structure, and can prolong service life of hauling cables.
Description
Technical field
The utility model relates to a kind of pulley, relates in particular to a kind of elevator traction machine pulley.
Background technology
Elevator, especially the elevator of vertical lift is to rely on the pulling force of many hauling ropes to do the vertical takeoff and landing (VTOL) operation aloft, in case hauling rope fracture in operational process, might cause casualties, the consequences such as device damage, therefore reduce the hauling rope wearing and tearing, can prevent the hauling rope fracture by actv. the service life that prolongs hauling rope, at present, the means that reduce the hauling rope wearing and tearing are varied, wherein comparatively commonly used is the oil lubrication that increases between hauling rope and the pulley, although this kind method is effectively simple, but waste lubricating oil, use too much lubricating oil not only can increase the maintenance cost of elevator, also pollute the environment, so the urgent hope of people can reduce by other means the wearing and tearing of hauling rope.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, can prolong the hauling rope elevator traction machine pulley in service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of elevator traction machine pulley, comprise the pulley body, have at least one and configuration part contacted slideway on the described pulley body, be provided with a plurality of balls along the circumference of described slideway.
Described ball is installed in the ball draw-in groove on the described slideway.
The surface of described ball is provided with ceramic layer.
Compared with prior art, the beneficial effects of the utility model are:
Because elevator traction machine of the present utility model is provided with a plurality of balls with pulley at the slideway of pulley body, this ball can reduce the area of contact with hauling rope in load-bearing, thereby can reduce the wearing and tearing of hauling rope, therefore the utility model is simple in structure, and can prolong the service life of hauling rope.
Description of drawings
Describe the utility model in detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present utility model.
Among the figure: pulley body 2, slideway 4, ball 6, ball draw-in groove 8.
The specific embodiment
As shown in Figure 1, a kind of elevator traction machine pulley of the present utility model, comprise pulley body 2, have at least one and the contacted slideway 4 of configuration part (hauling rope) on this pulley body 2, special feature of the present utility model is: the circumference along slideway 4 is provided with a plurality of balls 6, this ball 6 is installed in the ball draw-in groove 8 on the slideway 4, and ball 6 can reduce the area of contact with hauling rope in load-bearing, thereby can reduce the wearing and tearing of hauling rope.
For further reducing mechanical wear, be provided with one deck ceramic layer on the surface of ball 6.
In sum, the utility model is simple in structure, and can prolong the service life of hauling rope.
The above only is better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
