Abstract
The utility model relates to a sealing piece, in particular to a dustproof sealing ring. The sealing ring comprises a framework, and sealing lips contacted with a shaft and arranged at the inner side of the framework; an oil seal is provided with at least three continuous sealing lips; the sealing lips face to the same direction and are sawtooth-shaped; the top of a lip mouth of the sealing lip is arc-shaped; an oil storage groove is formed at each lip mouth of each sealing lip; lubricating grease is coated and contained in the oil storage groove; the outer annular surface of the framework is an exposed framework; and rubber is coated between the inner annular side of the framework and the sealing lip. The sealing ring has a simple structure, can effectively prevent muddy water from entering, greatly improves the sealing performance of the sealing lip, and prolongs the service life of the sealing ring.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of dust-proof seal ring.
Background technique
Ploughing or in the rice field, need touch in the muddy water during operation in positions such as the tugboat of tractor vehicle bridge, gearbox, wheel shaft, wheeled or crawler reaper, upper saw pulley; A large amount of earth or muddy water can enter into enclosure interior; Cause parts such as gear, bearing to get rusty, abnormal sound takes place or cause the rotation difficulty.Existing anti-dust seal is as shown in Figure 1, and this oil sealing can prevent that muddy water from getting into, but this oil sealing is fragile, leaks easily, poor sealing performance, and working life is shorter.
The model utility content
The purpose of the utility model is to have proposed a kind of dust-proof seal ring, and it is simple in structure, can prevent effectively that muddy water from getting into, and has improved the sealability of sealing lip greatly, has prolonged the working life of seal ring.
The utility model is that the technological scheme below adopting realizes: a kind of dust-proof seal ring, comprise skeleton and with the sealing lip that is coupling and touches, sealing lip is positioned at the inboard of skeleton; Wherein, described oil sealing is provided with at least three road continuous seal lips, each road sealing lip towards identical; The sealing lip indentation; The lip top of sealing lip is a circular arc, forms oil storage tank between the lip of each road sealing lip respectively, is coated with in the oil storage tank lubricating grease is housed; The annular outer surface of skeleton all is coated with rubber for exposing skeleton between the annular inboard of skeleton to the sealing lip.
In the utility model, the thickness of said rubber is 2-5mm.
The beneficial effect of the utility model is: through the internal surface at seal ring continuous zigzag fashion sealing lip is set, can improves the area of contact of sealing lip lip and axle, the surface friction drag when reducing rotation; Simultaneously,, increased the hold power of seal ring, stoped muddy water to get into effectively, improved the sealability of seal ring greatly, and prolonged the working life of seal ring axle because the inboard of skeleton all is coated with rubber until the sealing lip place.
Description of drawings
Fig. 1 is the half sectional view of existing anti-dust seal;
Fig. 2 is the half sectional view of dust-proof seal ring in the utility model.
Among the figure: 1 skeleton; 2 sealing lips; 3 oil storage tanks; 4 rubber.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 2 is the described dust-proof seal ring of the utility model.The sealing circle comprises skeleton 1 and sealing lip 2, and sealing lip 2 is positioned at the inboard of skeleton 1.In the sealing circle, with the position of touching that is coupling be sealing lip 2, the oil sealing in the present embodiment is provided with three road continuous seal lips 2, three seals lip 2 towards identical, the sealing lip indentation, the lip top of three seals lip 2 is circular arc.The sealing lip of this structure both can improve the area of contact of sealing lip lip and axle, had reduced the surface friction drag when oil sealing rotates simultaneously again, had improved the sealability of seal ring.Form oil storage tank 3 between the lip of three seals lip 2 respectively, be coated with in the oil storage tank 3 lubricating grease is housed, during the axle rotation, lubricating grease can play lubrication, the resistance when having reduced the axle rotation and the wearing and tearing of sealing lip lip.The annular outer surface of skeleton 1 is for exposing the skeleton form, and it can improve the installation precision of oil sealing, keeps good thermal diffusivity.The annular inboard of skeleton 1 all is coated with rubber 4 between sealing lip 2, the thickness of rubber 4 is 2-5mm.Utilize the elasticity of rubber 4, can increase the hold power of sealing lip lip greatly, stop the entering of outside muddy water, improved the anti-muddy water effect of seal ring axle.
In the utility model, described seal ring also can be provided with more multiple tracks continuous seal lip 2, is not limited to the three seals lip in the present embodiment.
Claims (2)
1. dust-proof seal ring, comprise skeleton (1) and with the sealing lip (2) that is coupling and touches, sealing lip (2) is positioned at the inboard of skeleton (1); It is characterized in that: said oil sealing is provided with at least three road continuous seal lips (2); Each road sealing lip (2) towards identical, sealing lip (2) indentation, the lip top of sealing lip (2) is a circular arc; Form oil storage tank (3) between the lip of each road sealing lip (2) respectively; Be coated with in the oil storage tank (3) lubricating grease is housed, the annular outer surface of skeleton (1) all is coated with rubber (4) for exposing skeleton between annular inboard to the sealing lip (2) of skeleton (1).
2. dust-proof seal ring according to claim 1 is characterized in that: the thickness of said rubber (4) is 2-5mm.
