Abstract
The invention discloses a combined sealing device for a dredging engineering transmission device. The combined sealing device comprises a frameless oil seal group, a pressure plate I, a pressure plate II, a rubber sealing plate and a connecting bolt, wherein the frameless oil seal group is arranged in a transparent cover of the transmission device, is combined by arranging two J-shaped frameless oil seals back to back, and is arranged in the transparent cover of the transmission device; the frameless oil sealing group is compressed by the pressure plate II; the rubber sealing plate sleeves the shaft head of the transmission device in a flared form under the elastic deformation action, and is compressed on one side of the pressure plate II through the pressure plate I; the connecting bolt passes through the pressure plate I, the rubber sealing plate and the pressure plate II in sequence to fix the pressure plate I, the rubber sealing plate and the pressure plate II on the transparent cover of the transmission device. The combined sealing device has a good sealing effect, is easy to machine and manufacture, is convenient to assemble, and is low in cost; external mud and water can be effectively prevented from entering equipment, and the service life of the equipment is prolonged.
Description
Technical field
The present invention relates to the seal arrangement that a kind of dredging works transmission device is used, especially relate to the sealer with assembled that a kind of dredging works transmission device is used.
Background technique
Water power plant is in running, and a large amount of reservoir areas need dredging works ship regularly to carry out silt cleaning, and as the core component in dredging works ship---transmission device, the quality of its performance directly has influence on the normal operation of engineering ship.Because transmission device contacts with silt with river for a long time, be easy to cause seal failure, cause silt access arrangement inside, and then the normal operation of the equipment of threat, cause oil leak to pollute river simultaneously.This patent proposes a kind of dredging works transmission combination formula sealing configuration for this reason, can effectively avoid the generation of the problems referred to above.
Summary of the invention
The object of the invention is to contact with silt with river for a long time for solving transmission device, be easy to cause seal failure, cause silt access arrangement inside, and then the normal operation of the equipment of threat, cause oil leak to pollute the problem of river simultaneously, the sealer with assembled that provides a kind of dredging works transmission device to use, novel structure of the present invention, convenient to water and silt good sealing effect, processing and assembling.
The present invention is the deficiency solving the problems of the technologies described above, and the technological scheme adopting is:
The sealer with assembled that a kind of dredging works transmission device is used, comprise the oil seal without framework group in the transparent cover that is arranged on transmission device, pressure plates I, pressure plates II, rubber gasket sheet and connecting bolt, described oil seal without framework group is by two J type oil seal without frameworks, adopt back-to-back form to combine, and be arranged in the transparent cover of transmission device, pressure plates II compresses oil seal without framework group, rubber gasket sheet is and on the horn-like spindle nose that is enclosed within transmission device and by pressure plates I, compresses a side that is arranged on pressure plates II under the effect of resiliently deformable, connecting bolt is successively through pressure plates I, rubber gasket sheet and pressure plates II are also fixed on them in the transparent cover of transmission device.
Described rubber gasket sheet adopts natural specific rubber sealing plate.
Described pressure plates I edge rounding.
The invention has the beneficial effects as follows: 1 good sealing effect, can effectively prevent extraneous silt and water access arrangement inside, extend service life of equipment.
2 easy manufacturing, easy to assembly, with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Graphical indicia: 1, pressure plates I; 2, rubber gasket sheet; 3, pressure plates II; 4, J type oil seal without framework; 5, transparent cover; 6, connecting bolt; 7, spindle nose.
Embodiment
Shown in figure, embodiment is as follows:
The sealer with assembled that a kind of dredging works transmission device is used, comprise the oil seal without framework group in the transparent cover 5 that is arranged on transmission device, pressure plates I 1, pressure plates II 3, rubber gasket sheet 2 and connecting bolt 6, described oil seal without framework group is by two J type oil seal without frameworks 4, adopt back-to-back form to combine, and be arranged in the transparent cover 5 of transmission device, pressure plates II 3 compresses oil seal without framework group, rubber gasket sheet 2 is on the horn-like spindle nose 7 that is enclosed within transmission device and is arranged on a side of pressure plates II 3 by pressure plates I 1 compression under the effect of resiliently deformable, connecting bolt 6 is successively through pressure plates I 1, rubber gasket sheet 2 and pressure plates II 3 are also fixed on them in the transparent cover 5 of transmission device.
Described rubber gasket sheet 2 adopts natural specific rubber sealing plate.
Described pressure plates I 1 edge rounding.
Adopt natural specific rubber sealing plate and one group of oil seal without framework to combine.One group of oil seal without framework comprises two J-shaped oil seal without frameworks, adopts back-to-back pattern to combine, and is arranged in transparent cover, then compresses by pressure plates II; The outside of oil seal without framework is furnished with natural specific rubber sealing plate; under the effect of resiliently deformable, be horn-like being enclosed within on spindle nose; and compress by pressure plates I; in order to protect natural specific rubber sealing plate; pressure plates I endoporus is carried out to rounding, ensure that pressure plates I endoporus and the contact of natural specific rubber sealing plate are good.Finally by bolt, pressure plates I, pressure plates II, natural specific rubber sealing plate and oil seal without framework are combined.Adopt above-mentioned sealing configuration, there is the features such as novel structure, good sealing effect, processing and assembling be convenient.
The technological scheme that the present invention is cited and mode of execution are not restrictions, in the cited technological scheme of the present invention and mode of execution is equal to or effect same approach is all protected in the present invention scope.
