Abstract
The utility model relates to a sprocket in particular to a central chain sprocket with large transport capacity and stability requirement for the large-sized mining machinery, steel and metallurgy industries. The utility model discloses a central chain with precision forging and high efficiency energy saving and a split type sprocket transmission combination, including a wheel core (1) and a flange (2). The outer edge of the flange (2) is a smooth cylinder surface, and the cross section is a step shape, while the middle of the flange is a convex friction surface (23). The two sides of the convex friction surface (23) are a left friction surface (22) and a right friction surface (23). So the utility model takes advantages of the friction surface of the sprocket with uniform wear and fatigue, reliable using of the sprocket and extending life period.
Description
Technical field
The utility model relates to a kind of sprocket wheel, and it is big and require the sprocket wheel of central chain stably to relate in particular to a kind of large-scale mine machinery, iron and steel, metallurgy industry quantity delivered of being used for.
Background technique
The sprocket wheel of precision forging central authorities chain is mainly used on large-scale mine machinery, iron and steel, the metallurgical conveying equipment, and it cooperates with central Conveying chains and has the big characteristics of quantity delivered.Sprocket wheel all adopts the common sprocket wheel that tooth is arranged at present, and as shown in Figure 1, this design causes the cylinder of chain to carry the worn area local fatigue with contacting of sprocket wheel easily, reduces working life.
Summary of the invention
The purpose of this utility model is to provide a kind of no tooth sprocket, guarantees the rubbing surface uniform wear of driving wheel, and is evenly tired, uses reliably, increases the service life.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is: precision forging high-efficiency and energy-saving type central authorities' chain and the combination of split sprocket driving comprise core wheel and wheel rim, described wheel rim, outer rim be smooth cylndrical surface, sectional shape is a stepped shape, middle rubbing surface for protruding.
As preferably, the both sides of the rubbing surface that protrudes in the middle of described are left and right sides rubbing surface.
Therefore, the utlity model has the rubbing surface uniform wear of sprocket wheel, evenly tired, sprocket wheel uses reliable, increases the service life.
Description of drawings
Fig. 1 is a kind of assembling schematic representation that tooth sprocket and chain are arranged of the utility model prior art.
Fig. 2 is embodiment 1 a structural representation.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is embodiment 1 the sprocket wheel and the assembling schematic representation of Conveying chains.
Embodiment
Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with the accompanying drawings 2 to accompanying drawing 4.
Referring to accompanying drawing 4, when carrying with the Conveying chains assembling, the rubbing surface 23 of the protrusion of embodiment's 1 described sprocket wheel contacts with the cylinder 31 of chain, and left and right sides rubbing surface 22,24 contacts with the carrier bar side plane 32 of cylinder 31 both sides.Make to carry and have good load distribution between the chain and sprocket, simultaneously by the sprocket wheel reducing, sprocket wheel rotates a circle like this, and the supporting point of Conveying chains and driving wheel produces displacement on sprocket wheel, and sprocket wheel constantly rotates, just constantly displacement of supporting point 41,42, guarantee the uniform wear of sprocket wheel, thereby the use that guarantees sprocket wheel is reliable, simultaneously, the wearing face of sprocket wheel is long-pending to increase the working life of guaranteeing sprocket wheel greatly.
Claims (2)
1, precision forging high-efficiency and energy-saving type central authorities' chain and the combination of split sprocket driving comprise core wheel (1) and wheel rim (2), and it is characterized in that: the outer rim of described wheel rim (2) is smooth cylndrical surface, and sectional shape is a stepped shape, middle rubbing surface (23) for protruding.
2, precision forging high-efficiency and energy-saving type central authorities' chain according to claim 1 and the combination of split sprocket driving, it is characterized in that: the both sides of the rubbing surface (23) that protrudes in the middle of described are left and right sides rubbing surface (22), (24).
