Description
Technical Field
The utility model relates to a sealed product technical field, concretely relates to novel axle sealing device.
Background
Many devices and equipment utilizing shaft transmissions are designed to frequently encounter sealing problems, and currently, the more common seals include packing seals, oil seals and mechanical seals. The packing seal mainly aims at the occasions with low requirements, no pressure and the like, such as a screw conveyer; the oil seal is mainly used for grease seal and is not suitable for dust and water seal working conditions, such as a gear box; the mechanical seal is mainly applied to places with high sealing requirements and occasions with pressure, such as a high-pressure reaction kettle.
The brush type scrubber is high-speed equipment, the highest speed is about 3600 r/min, the medium is water and gas, and the mechanical seal and the oil seal are not suitable, so the packing seal is selected as the shaft seal in the initial design, but the phenomena of liquid leakage, large shaft load and high temperature are found in the actual production, and the driving rate of the equipment is seriously influenced.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is to provide a novel shaft sealing device to solve the liquid leakage, the large shaft load and the high temperature phenomenon.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
the utility model provides a novel shaft sealing device, which comprises a hexagon bolt, a flat gasket, a sealing ring, a connecting shaft, a shaft sleeve and a shell; the sealing ring is fixed on the shell through the hexagon bolt and the flat gasket, the sealing gasket is positioned between the sealing ring and the shell, and the shaft sleeve is sleeved on the connecting shaft and forms two sealing surfaces with the sealing ring.
Further, the clearance between the sealing ring and the shaft sleeve is uniform.
Specifically, the gap is 0.05 mm.
Further, the sealing ring is of an inner groove structure.
The utility model discloses beneficial effect as follows:
1) the utility model provides a novel shaft sealing device, which is adopted, the sealing ring is not contacted with the shaft sleeve, the heat productivity of the shaft is zero, and the shaft power is greatly reduced;
2) the utility model provides a novel shaft sealing device, which is adopted, the shaft is more reasonably supported by two points of a bearing, the original over-positioning phenomenon is improved, the structure is compact, and the space is saved;
3) the utility model provides a novel shaft seal device adopts the device, does not have the leakage, operates steadily, and the installation is maintained more conveniently, more swiftly.
Drawings
Fig. 1 is the utility model discloses embodiment a novel shaft seal device schematic diagram:
wherein: the structure comprises a hexagon bolt 1, a flat gasket 2, a sealing gasket 3, a sealing ring 4, a connecting shaft 5, a shaft sleeve 6 and a shell 7.
Detailed Description
In order to understand the features and technical contents of the present invention in more detail, the following description is given in conjunction with the accompanying drawings and embodiments, which are only for reference and not for limitation.
As shown in fig. 1, the embodiment of the present invention provides a novel shaft sealing device, which includes a hexagon bolt 1, a flat gasket 2, a sealing gasket 3, a sealing ring 4, a connecting shaft 5, a shaft sleeve 6, and a housing 7. The sealing ring 4 is a main sealing element and is of an inner groove structure, the sealing ring is not in contact with the shaft sleeve, the heat productivity of the shaft is zero, and the shaft power is greatly reduced. The sealing ring 4 is fixed on the shell 7 through the hexagon bolt 1 and the flat gasket 2, the sealing gasket 3 is positioned between the sealing ring 4 and the shell 7, and the shaft sleeve 6 is sleeved on the connecting shaft 5 to form two sealing surfaces with the sealing ring 4. The shaft is more reasonably supported by two points of the bearing, the original over-positioning phenomenon is improved, the structure is compact, and the space is saved. When the sealing ring is installed, the gap between the sealing ring and the shaft sleeve must be ensured to be uniform and not to deviate. The leakage is caused when the device is used, the operation is stable, and the installation and the maintenance are more convenient and quicker.
The above-mentioned general knowledge is not described in detail, and can be understood by those skilled in the art.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
