Abstract
The utility model discloses an oil seal with an oil block structure, comprising a support framework and a sealing body, wherein a sealing lip is arranged at the inner side of the sealing body. The oil seal is characterized in that an oil block ring corresponding to an opening of a sealing lip is arranged above the sealing lip, a support foot is arranged at the side part of the oil block ring, an annular slot is arranged at the outer side of the sealing lip, and the support foot of the oil block ring is fixed in the annular slot. As the oil seal adopts the structure that the sealing lip is arranged above the oil block ring, the direct impact of a sealing medium on the opening of the sealing lip can be avoided effectively, therefore, the structure is simple, and the installation is convenient.
Description
Technical field
The utility model relates to the seal arrangement technical field, relates to a kind of oil seal structure in particular.
Background technique
Oil sealing is to be used for the mechanical component of oil sealing, and it seals the parts that need in the transmission part to lubricate and the parts of exerting oneself, and prevents leakage of oil, guarantees that mechanical part moves under lubricating condition, prevents dry friction, is unlikely to allow oil seepage.Can be divided into various ways and different calls from seal action, characteristics, structure type, working state and the sealing mechanism etc. of oil sealing, but traditionally generally with rotary shaft lip seal on oil sealing, static seal and motive sealing (general to-and-fro motion) with Sealing Sealing.The position that in every operating body case lubricating oil is arranged and be connected with the outside all needs oil sealing, but oil sealing in the course of the work, and sealing medium directly impacts its seal lip, causes the sealing lip elastic strain easily, influences the lip seal effect.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, long service life, and good seal performance, and can solve the oil sealing with oil baffle structure of the problem that the impact of sealing medium brings.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of oil sealing with oil baffle structure, comprise support frame and seal, the inboard of seal is provided with sealing lip, it is characterized in that, the top of described seal lip is provided with the oil deflector corresponding with it.
As further specifying of such scheme, the sidepiece of described oil deflector is provided with supporting foot, and the sealing lip arranged outside has annular groove, and the supporting foot of oil deflector is fixed in the annular groove.
The top of described sealing lip is provided with the leaf tail, and the arranged outside of leaf tail has the spring ditch of mounting spring, and the side supports pin of oil deflector is packaged in spring in the spring ditch.
Described oil deflector is a ring segment, and the outer rim of this ring segment is embedded on the sidewall of seal.
Described oil deflector is a nylon ring.
Described oil deflector surface is evenly distributed with if a through hole.
The internal diameter of described oil deflector is greater than the internal diameter of sealing lip.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the oil deflector structure is set above sealing lip, prevents the direct impact of sealing medium to seal lip, guarantees the sealing of oil sealing.

Fig. 2 is the partial enlarged drawing of Fig. 1.
Description of reference numerals: 1, support frame 2, seal 3, sealing lip 4, oil deflector 5, through hole 6, supporting foot 7, annular groove 8, leaf tail 9, spring ditch
Embodiment
As shown in Figure 1 and Figure 2, a kind of oil sealing of the utility model with oil baffle structure, comprise support frame 1 and seal 2, the inboard of seal 2 is provided with sealing lip 3, the top of seal lip is provided with the oil deflector corresponding with it 4, oil deflector 4 is generally nylon ring, and oil deflector 4 surfaces are evenly distributed with as if a through hole 5, and the internal diameter of oil deflector 4 is greater than the internal diameter of sealing lip.The sidepiece of oil deflector 4 is provided with supporting foot 6, and sealing lip 3 arranged outside have annular groove 7, and the supporting foot of oil deflector is fixed in the annular groove 7.The top of sealing lip is provided with leaf tail 8, and the arranged outside of leaf tail 8 has the spring ditch 9 of mounting spring, and the side supports pin of oil deflector is packaged in spring in the spring ditch.
In the using process, when sealing medium impacts to the seal lip direction, sealing medium directly act on the oil deflector structure on, at this moment, the oil deflector structure plays a protective role to seal lip, thereby weakens the suffered impact force of sealing lip.
Above-described only is preferred implementation of the present utility model, and described oil deflector can also be set to a ring segment, and the outer rim of this ring segment is embedded on the sidewall of seal.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
