Abstract
A high-altitude paying-off wheel comprises a bearing seat (1), a wheel hub (2), a supporting disk (3), and an elastic wear layer (4). The wheel hub (2) is respectively connected with the bearing seat (1) and the supporting disk (3), and the elastic wear layer (4) is arranged inside an arc-shaped wire groove (7) of the supporting disk (3). The high-altitude paying-off wheel is characterized in that an annular positioning groove (8) is arranged at the bottom of the arc-shaped wire groove (7), and a positioning bulge (5) which is matched with the annular positioning groove (8) and is used for nesting the annular positioning groove (8) is arranged at the bottom of the elastic wear layer (4). The high-altitude paying-off wheel has the advantages of simple structure, convenient manufacturing, and reliable positioning of the elastic wear layer.
Description
Technical field
The utility model relates to a kind of power construction parts, especially a kind ofly be used for actinobacillus wheel that cable when tension between the adjacent iron tower used and similarly pulley and friction pulley etc. have the various slide relative and the drive disk assembly thereof of special requirement, specifically a kind of high-altitude actinobacillus wheel.
Background technology
At present; when the stringing of high-altitude; it is sagging for power cable is reduced; must use actinobacillus wheel that it is strained; existing actinobacillus wheel mostly is Al-alloy parts or engineering plastics cast structural member greatly; Al-alloy parts weight is big; processed complex; especially for the lead of having relatively high expectations; cause fraying of lead in order to prevent the metal surface; need in metal arc metallic channel, twine anti-wear material and flood hot pressing formation protective layer again; long construction period; the average process-cycle is more than one hour; therefore utilizing the engineering plastics castable is a more satisfactory manufacturing process; and engineering plastics have in light weight; the advantage that intensity is high; but because its hardness is much larger than the hardness on electrical lead surface; therefore also can cause damage to the sheath on plain conductor surface; therefore also must with the contacted supporting disk of lead in the elastic wear-resisting layer is installed, existing elastic wear-resisting layer is to rely on elastic force to be positioned in the groove of supporting disk mostly, can be owing to deviation phenomenon takes place unbalance stress in the use; cause plain conductor directly to contact with the supporting disk surface; the aggravation wearing and tearing, therefore, it is the key that improves the actinobacillus wheel quality that the elastic wear-resisting layer is located in supporting disk.
Summary of the invention
The purpose of this utility model is in use can sideslip occur and the problem that causes wearing and tearing and take place at the elastic wear-resisting layer in the supporting disk of existing high-altitude actinobacillus wheel, designs a kind of elastic wear-resisting layer that can make and is positioned at high-altitude actinobacillus wheel in the supporting disk.
The technical solution of the utility model is:
A kind of high-altitude actinobacillus wheel, it comprises bearing pedestal 1, wheel hub 2, supporting disk 3 and elastic wear-resisting layer 4, wheel hub 2 links to each other with supporting disk 3 with bearing pedestal 1 respectively, elastic wear-resisting layer 4 is installed in the arc wire grooves 7 of supporting disk 3, the bottom that it is characterized in that described arc wire grooves 7 is provided with annular positioning groove 8, and the bottom of elastic wear-resisting layer 4 is provided with 8 that match with annular positioning groove, as to be used for being inlaid in annular positioning groove 8 positioning convex 5.
The thickness of described elastic wear-resisting layer 4 is grading structure, and thick more the closer to positioning convex 5 places.
Described elastic wear-resisting layer 4 is plastics, rubber or plastic cement.
Described bearing pedestal 1, wheel hub 2 and supporting disk 3 are engineering plastics or metal integral shaped structure.
The cross sectional shape of described annular positioning groove 8 is arc, polygon or its combination.
The beneficial effects of the utility model:
The utility model is simple in structure, and is easily manufactured, and elastic wear-resisting layer location is reliable.
The utility model scope of application is wide, not only can be used for high-altitude electric power unwrapping wire, and can be widely used in occasions such as communication, hoisting equipment, cable car, mixer.

Fig. 1 is the structural representation of facing of actinobacillus wheel of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1 of reflection actinobacillus wheel supporting disk structure of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of high-altitude actinobacillus wheel, comprise and utilize injection mo(u)lding enhancement engineering plastic shaft bearing of making 1 and the wheel hub 2 that links to each other with bearing pedestal 1 integral body, the whole supporting disk 3 (Fig. 2) that is connected with the curved groove in cross section on the wheel hub 2, in order to strengthen the bearing strength of arc supporting dish, two lateral surfaces of described supporting disk 3 are provided with and also are the short reinforcement 6 that extends to wheel hub 2 surfaces of arc; Wheel hub 2 is a thin-wall construction spare, which is provided with lightening hole 9 and the long reinforcement 10 that extends to bearing pedestal 1, as shown in Figure 1, the bottom of the arc wire grooves 7 of supporting disk 3 is provided with annular positioning groove 8, the shape of location notch 8 can be polygons such as circular arc, square, rectangle, also can be arc and polygonal combination, the bottom of elastic wear-resisting layer 4 is provided with a positioning convex 5 that matches with location notch 8, thereby positioning convex 5 is fitted in the location notch 8 and makes it be positioned at supporting disk, the thickness of elastic wear-resisting layer 4 is preferably made grading structure, and thick more the closer to center position.As shown in Figure 2.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
