Abstract
The utility model provides a boat-bottom-shaped oil return thread type oil seal for a high-speed rotating shaft, and relates to the technical field of rotating oil seals for shafts. The boat-bottom-shaped oil return thread type oil seal comprises an oil-seal main lip, a cushion platform is arranged behind the main lip and is a rectangular body, an oil return thread is arranged on the surface of the cushion platform, and the oil return thread is a boat-bottom-shaped boss. The height a of the cushion platform ranges from 0.5mm to 1mm. The distance c between the highest point of the boat-bottom-shaped boss which is the oil return thread and the cushion platform ranges from 1mm to 2mm. The boat-bottom-shaped oil return thread type oil seal has the advantages that the oil return thread of the main lip of the oil seal is designed into the boat-bottom shape, sealing performance is improved when the main lip abrades the shaft, and service life of the main lip is prolonged.
Description
Technical field:
The utility model relates to running shaft and uses the oil seal technique field, is specifically related to a kind of sealing for axle that is adapted to High Rotation Speed.
Background technique:
At present, in the application of High Rotation Speed oil sealing, in order to strengthen the pump-absorb action of main lip, improve the sealability of main lip, usually at main lip air side design return wire, but current return wire shape is all parallel return wire, it is not enough, and point is that lip is after the wearing and tearing of regular period, and the pump-absorb action of return wire has just reduced.
The model utility content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency, and oil return line style high-speed rotating shaft oil sealing at the bottom of a kind of a kind of boat rational in infrastructure, simple to operate, easy to use is provided.
Technical problem to be solved in the utility model adopts following technological scheme to realize:
At the bottom of a kind of boat, oil return line style high-speed rotating shaft oil sealing, comprise oil sealing master lip, and described main lip back is provided with the pad platform, and described pad platform is rectangular body, and described pad platform surface is provided with oil drive back thread, the boss that described oil drive back thread is the boat Bottom Shape.
As optimal way, described pad platform height is a, and a is 0.5～1mm.
As optimal way, at the bottom of the boat of described oil drive back thread, shape boss peak is c to pad platform height, and c is 1～2mm.
The beneficial effects of the utility model are: the utility model is designed to the boat Bottom Shape by the main lip return wire of oil sealing, the sealing while having improved lip and axle abrasion, and the working life of having improved main lip.
The accompanying drawing explanation:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model master lip configurations schematic diagram;
Fig. 2 is the structural representation after the utility model assembling.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, at the bottom of a kind of boat, oil return line style high-speed rotating shaft oil sealing, comprise oil sealing master lip 1, and described main lip 1 back is provided with pad platform 2, and described pad platform 2 is rectangular body, and described pad platform 2 surfaces are provided with oil drive back thread 3, the boss that described oil drive back thread 3 is the boat Bottom Shape.
As described in Figure 2, described pad platform 2 is highly a, and a is 0.5～1mm.At the bottom of the boat of described oil drive back thread 3, shape boss peak is c to pad platform height, and c is 1～2mm.
The utility model is designed to the boat Bottom Shape by the main lip of oil sealing 1 return wire 3, the sealing while having improved lip and axle abrasion, and the working life of having improved main lip 1.
Above demonstration and described 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; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
