Abstract
The utility model relates to a composite shaft oil seal. A framework oil seal of the existing shaft oil seal is easily interfused with sundries, thereby leading to the abnormal abrasion of the framework oil seal. Therefore, the composite shaft oil seal comprises a bearing gland, wherein a framework oil seal is arranged at the outer side of a centre hole of the bearing gland; the composite shaft oil seal is characterized in that an oil seal gland is also arranged outside the bearing gland; a circular groove is arranged at the outer side of the hole wall of a center hole of the oil seal gland; the circular groove is internally embedded with an O-shaped ring; and a non-framework oil seal is arranged at the inner side of the hole wall of the center hole of the oil seal gland. With the adoption of the design, the O-shaped ring and the non-framework oil seal are additionally arranged outside the framework oil seal, so that firewood and sand can be blocked outside the framework oil seal; and when abrasion occurs to the outer O-shaped ring and the non-framework oil seal, the replacement is very convenient. The bearing gland and the oil seal gland can be connected with each other by screw thread or by a nut. The composite shaft oil seal has the advantage of simple structure and is convenient to disassembly/assembly, therefore, the lives of the oil seal and a bearing are greatly prolonged, and the composite shaft oil seal can be particularly applicable to various agricultural machines.
Description
Technical field
The utility model relates to a kind of composite shaft oil sealing.
Background technique
Existing shafting oil package is drawn together bearing gland, and this bearing gland center hole outside is provided with outside framework oil seal.When being used for agricultural machinery, faggot, silt particle can enter outside framework oil seal inside along the gap between axle and the oil sealing, cause the outside framework oil seal heel and toe wear.
The model utility content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of composite shaft oil sealing is provided.
For solving the problems of the technologies described above, this composite shaft oil sealing comprises bearing gland, this bearing gland center hole hole wall outside is provided with outside framework oil seal, it is characterized in that: described bearing gland also is provided with an oil sealing cover outward, this oil sealing cover center hole hole wall outside is provided with annular groove, this annular groove is embedded with O shape circle, and this oil sealing cover center hole hole wall inboard is provided with exoskeletal oil sealing.Between bearing gland and the oil sealing cover, can also can connect by being threaded by screw.
So design outside outside framework oil seal, is set up O shape circle and exoskeletal oil sealing, faggot, silt particle can be blocked in outside the outside framework oil seal, when O shape circle and exoskeletal oil sealing appearance wearing and tearing, changes also very convenient.
As optimization, evenly have a plurality of through holes on the described oil sealing cover, have tapped blind hole on the relevant position of described bearing gland, and be furnished with set screw.So design is simple in structure, easy accessibility.
The utility model composite shaft oil sealing has simple in structure, and the advantage of easy accessibility can greatly prolong life-span of oil sealing and bearing, is particularly suitable for various agricultural machinery and uses.
Description of drawings
Below in conjunction with accompanying drawing this composite shaft oil sealing is described further:
Fig. 1 is the structural representation of this composite shaft oil sealing;
Fig. 2 is that the A-A of composite shaft oil sealing shown in Figure 1 is to cross-sectional view.
Fig. 3 is the explosive view of composite shaft oil sealing shown in Figure 1.
Among the figure: 1 be bearing gland, 2 for the bearing gland center hole, 3 for oil sealing cover, 4 for annular groove, 5 for O shape circle, 6 for exoskeletal oil sealing, 7 for tapped blind hole, 8 be set screw.
Embodiment
Mode of execution one: as Figure 1-3, this composite shaft oil sealing comprises bearing gland 1, this bearing gland center hole 2 hole walls outside is provided with outside framework oil seal (not going out among the figure), it is characterized in that: also be provided with an oil sealing cover 3 outside the described bearing gland 1, this oil sealing cover 3 center hole hole walls outside is provided with annular groove 4, this annular groove 4 is embedded with O shape circle 5, and these oil sealing cover 3 center hole hole wall inboards are provided with exoskeletal oil sealing 6.
Evenly have 6 through holes on the described oil sealing cover 3, have tapped blind hole 7 on the relevant position of described bearing gland 1, and be furnished with set screw 8.
