Abstract
The invention discloses a pulley wheel for an elevator tractor, comprising a pulley wheel body (2), wherein at least one of slide ways (4) contacted with configuring pieces are arranged on the pulley wheel body (2). The pulley wheel is characterized in that a plurality of balls (6) are arranged along the peripheries of the slide ways (4). The pulley wheel for the elevator tractor is simple in simple, and the service life of a haulage cable can be prolonged.
Description
Technical field
The present invention relates to a kind of pulley, relate in particular to a kind of elevator traction machine and use pulley.
Background technology
The elevator of elevator, especially 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 ruptures in operational process; Might cause casualties, consequence such as device damage, therefore reduce the hauling rope wearing and tearing, can prevent that hauling rope from rupturing by actv. the service life that prolongs hauling rope; At present; It is varied to reduce hauling rope worn-down means, and wherein comparatively commonly used is the oil lubrication that increases between hauling rope and the pulley, though 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 the wearing and tearing of hauling rope through other means.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure, and the elevator traction machine that can prolong hauling rope service life is used pulley.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of elevator traction machine is used pulley, comprises the pulley body, has at least one and the contacted slideway of configuration part on the said pulley body, and the circumference of the said slideway in edge is provided with a plurality of balls.
Said ball is installed in the ball draw-in groove on the said slideway.
The surface of said ball is provided with ceramic layer.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention is provided with a plurality of balls with the slideway of pulley 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, so the present invention is simple in structure, and can prolongs the service life of hauling rope.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a structural representation of the present invention.
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 of the present invention is used pulley, comprises pulley body 2, has at least one and the contacted slideway 4 of configuration part (hauling rope) on this pulley body 2; Special feature of the present invention 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 present invention is simple in structure, and can prolong the service life of hauling rope.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
1. an elevator traction machine is used pulley, comprises pulley body (2), has at least one and the configuration contacted slideway of part (4) on the said pulley body (2), and it is characterized in that: the circumference along said slideway (4) is provided with a plurality of balls (6).
2. elevator traction machine according to claim 1 is used pulley, it is characterized in that: said ball (6) is installed in the ball draw-in groove (8) on the said slideway (4).
