Description
Technical field
The utility model relates to running shaft lip type oil seal lip protecting jacket, belongs to the sealing configuration mounting technology field of running shaft lip type oil sealing.
Background technique
In prior art, the subssembly drawing of lip type oil sealing only has four parts compositions, lip type oil sealing, casing, bearing and running shaft, in the sealing configuration assembling of running shaft lip type oil sealing, running shaft directly assembles through the lip of lip type oil sealing by usual employing, because the sharp edge on running shaft, corner angle, tiny burr (having keyway place especially), surface roughness are excessive etc., the lip of lip type oil sealing is easy to be scratched by rotating shaft surface cause leakage of oil (and not easily finding).
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide running shaft lip type oil seal lip protecting jacket.
Running shaft lip type oil seal lip protecting jacket of the present utility model, it comprises guide sleeve, protecting jacket, lip type oil sealing, casing and bearing; Guide sleeve is socketed in protecting jacket; lip type oil-sealing sleeve is connected on the outside of protecting jacket, and lip type oil sealing and protecting jacket are interference fit, and the outside of lip type oil sealing is socketed with casing; and lip type oil-sealing sleeve is connected on one end of box inside, the other end of box inside is socketed with bearing.
As preferably, surface roughness Ra≤0.4 μ of the outer surface of the lip of lip type of pouring into the oil sealing of described guide sleeve and protecting jacket.
The beneficial effects of the utility model are: its structure is simple, and cost easy to manufacture is low, easy to use, improves the quality of products, and reduce axle manufacture cost, improve efficiency of assembling.

Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As Figure 1-3, this embodiment by the following technical solutions: it comprises guide sleeve 1, protecting jacket 2, lip type oil sealing 3, casing 4 and bearing 5; Guide sleeve 1 is socketed in protecting jacket 2; lip type oil sealing 3 is socketed in the outside of protecting jacket 2, and lip type oil sealing 3 and protecting jacket 2 are interference fit, and the outside of lip type oil sealing 3 is socketed with casing 4; and lip type oil sealing 3 is socketed in the one end inside casing 4, the other end inside casing 4 is socketed with bearing 5.
Further, surface roughness Ra≤0.4 μ of the outer surface of the lip of lip type of pouring into the oil sealing of described guide sleeve 1 and protecting jacket 2.
The step that running shaft and lip type oil sealing sealing are assembled is by this embodiment:
1, as shown in Figure 4, guide sleeve 1 is loaded in protecting jacket 2, and end face is sturdy.
2, guide sleeve 1 and protecting jacket 2 are loaded in the lip of lip type oil sealing in the lump, and due to the equal smooth transition in surface of all importing oil seal lips, surface roughness Ra≤0.4 μ, so have fine protection to oil seal lip.
3, as shown in Figure 5, take out guide sleeve 1, because protecting jacket 2 and oil seal lip have larger magnitude of interference, so oil seal lip can tightly bind round on protecting jacket 2, facilitate the taking-up of guide sleeve 1.
4, as shown in Figure 6, running shaft 6 is installed in the endoporus of protecting jacket 2, and installs to oil sealing position by Product Assembly figure requirement.
5, as shown in Figure 7, take out protecting jacket 2, oil seal lip will tightly be bound round on the rotary shaft naturally by resiliently deformable.
6, install.
The advantage of this embodiment has:
1, project organization is simple, and cost easy to manufacture is low, easy to use and flexible.
2, because running shaft is arranged in oil sealing by protecting jacket, to the lip of oil sealing, there is good protection, thus greatly reduce the possibility of product from oil sealing leakage of oil, improve the quality of product.
3, to the requirement of the non-matching surface of the running shaft of product lower (being protection oil seal lip and carry high-precision surface), thus reduce axle manufacture cost.
4, when ensureing product variety, greatly improve efficiency of assembling.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
