Abstract
The utility model provides a sealing device of an output shaft, which is provided with a skeleton oil seal and a skeletonless oil seal on the output shaft, wherein the skeleton oil seal and the skeletonless oil seal are separated by a spacing sleeve; an oil cavity is arranged between the skeleton oil seal and the skeletonless oil seal and below the spacing sleeve; the outer parts of the skeleton oil seal, the skeletonless oil seal and the spacing sleeve are provided with through covers; the middle of the through cover is provided with an oil inlet hole, and the top part thereof is provided with a forced filling oil cup; and one end of the skeletonless oil seal is provided with a gland which is fixed on the through cover by a bolt. The sealing device is provided with a double-oil-seal structure, has better sealing effect for the output shaft, can conduct lubrication at the two sides of the outputting shaft, and has simple structure and convenient installation and dismantling.
Description
Technical field
The utility model relates to the shaft sealing field, specially refers to the output shaft seal arrangement.
Background technique
Single oil sealing is adopted in the sealing of output shaft at present mostly, therefore just exists in use for some time, produces the phenomenon that oil impregnate and sealability descend, and single oil sealing can only carry out one-sided lubricatedly, changes very inconvenience and complex structure and install.
Summary of the invention
The purpose of this utility model is to provide a kind of dual-oil seal that has, and oil pocket is big and the lubricated output shaft seal arrangement in energy both sides.
For achieving the above object, the technical solution of the utility model is:
Outside framework oil seal and exoskeletal oil sealing are housed on the output shaft in the output shaft seal arrangement, separate with spacer between outside framework oil seal and the exoskeletal oil sealing, between outside framework oil seal, the exoskeletal oil sealing and spacer below oil pocket is arranged, logical lid is housed in the outside of outside framework oil seal, exoskeletal oil sealing and spacer, there is oil inlet hole centre at logical lid, oil inlet hole passes its bottom of spacer and is connected with oil pocket, and the top that forced filling oil cup is installed in logical lid is connected with the top of oil inlet hole.One end of exoskeletal oil sealing is equipped with gland, and gland is fixed by bolts to logical covering.
Good effect of the present utility model is:
1, because of being the dual-oil seal structure, the sealing effect of output shaft is better;
2, used spacer to enlarge the unit area of oil pocket;
3, can carry out bilateral to output shaft lubricates;
4, simple in structure, easy installation and removal.
Description of drawings
Fig. 1, output shaft schematic diagram of sealing device;
Fig. 2, output shaft seal arrangement partial enlarged drawing.
Embodiment
Further specify the utility model embodiment below in conjunction with accompanying drawing 1-2.
With reference to Fig. 1, on output shaft 1, load onto outside framework oil seal 2 and exoskeletal oil sealing 6 respectively, between outside framework oil seal 2 and exoskeletal oil sealing 6, load onto spacer 3, will lead to then and cover 5 and be contained in outermost, adorn gland 8 usefulness bolts 7 at last and be fixed on logical the lid on 5.Add fashionable to forced filling oil cup 4 lubricating grease, with reference to Fig. 2, lubricating grease flows in the oil pocket 9 through oil inlet hole 10, and output shaft 1 is lubricated, and the lubricating grease of outside framework oil seal 2 and the infiltration of exoskeletal oil sealing 6 subtend both sides seals, and spacer 3 separates the lubricating grease of dishing out upward.Because exoskeletal oil sealing 6 is soft, therefore the dust that advances thoroughly from gland 8 also can be separated by exoskeletal oil sealing 6, has prevented that dust from entering the wearing and tearing to output shaft 1, and exoskeletal oil sealing 6 can be further to output shaft 1 sealing, to prevent oil impregnate simultaneously.
