Description
Technical Field
The utility model relates to a coal-winning machine drive wheel technical field, concretely relates to double web five-tooth drive wheel for thin seam coal-winning machine.
Background
The coal mining machine is a special engineering machine for underground coal mining of a coal mine, the coal mining machine travels and cuts coal along a stope face underground, and the traveling mechanism of the existing coal mining machine mostly travels in a mode of meshing a cycloid wheel and a pin row. In a walking mechanism, a driving wheel is often adopted to drive a walking wheel, and the walking wheel is meshed with a pin row to output forward power. On a traveling mechanism of a thin coal seam mining machine, because of the limitation of size space, in the current market, a six-tooth driving wheel is most commonly meshed with a seven-tooth traveling wheel, but because the thin coal seam mining machine is limited by the thickness of a machine body and the strength of the machine body, the current six-tooth driving wheel meshed with the seven-tooth traveling wheel has smaller traction force configuration and poor climbing capability; if the traction force is improved by increasing the transmission ratio of the inner cavity gear, the thickness of the machine body is further increased, and the matching requirement of the thin seam coal mining machine cannot be met. Therefore, under the condition that the size of the thin coal seam mining machine is not changed, the traction force is improved, and the design difficulty of the thin coal seam mining machine is achieved.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, the utility model aims at providing a double web five-tooth drive wheel for thin seam coal mining machine adopts the form of five-tooth drive wheel, increases the drive ratio, promotes coal-winning machine traction force to overcome above-mentioned prior art not enough.
The utility model provides a double web five-tooth drive wheel for thin seam coal mining machine includes: the five-tooth cycloidal gear comprises a five-tooth cycloidal gear, wherein a first web plate is integrally formed on one side of the five-tooth cycloidal gear, a second web plate welded on teeth of the five-tooth cycloidal gear is arranged on the other side of the five-tooth cycloidal gear, a mandrel is integrally formed in the center of the five-tooth cycloidal gear along the axial direction, the first web plate is circular, the diameter of the first web plate is consistent with that of the five-tooth cycloidal gear, the second web plate is composed of five sub-web plates, the five sub-web plates are respectively welded in tooth gaps of the five-tooth cycloidal gear along the radial direction, the five teeth of the five-tooth cycloidal gear and the five sub-web plates are circular after being welded, the teeth between the first web plate and the second web plate are meshed with seven-tooth traveling wheels, an optical axis is arranged on one side.
The utility model has the advantages and positive effects that: the five-tooth driving wheel used by the utility model increases the transmission ratio, improves the traction force of the coal mining machine, reduces the five teeth on the basis of the original six-tooth driving wheel, and increases the transmission ratio by 20%; the cycloidal tooth profile of the driving wheel is adjusted, and the meshing contact ratio is improved; the double-web structure is added, the strength of the five-tooth driving wheel is improved, and the application of the five-tooth driving wheel with the minimum tooth number of the coal mining machine on the coal mining machine is further ensured.
