Abstract
The utility model discloses a bearing sealing ring, which comprises an annular steel support and a rubber ring coated on the steel support. The outer edge of the rubber ring is equipped with a sealing ligula. An oil storage chamber is arranged inside the sealing ligula. A support ring arranged inside the oil storage chamber is a spring ring. According to the utility model, a support ring is additionally arranged inside the sealing ligula of the bearing sealing ring. When the sealing ligula is extruded under the action of an external force, the support ring plays a support role so as to avoid the deformation of the sealing ligula. Therefore, the lubricating oil inside the sealing ligula will not leak to the outside and the performance of the bearing is ensured.
Description
Technical field
The utility model relates to a kind of Sealing, relates to a kind of bearing sealed ring that prevents that the roller oil leak between the bearing enclose from coming out specifically.
Background technique
Existing bearing generally includes an outer ring, an inner ring and is slidingly connected at several rollers in the retainer, outer ring and inner ring through with the relative rolling of roller; Realize relatively rotating of outer ring and inner ring, the friction of, inner ring outer and roller for reducing, the while also is the cooling for external, inner ring and roller surface of contact; Usually between outer ring and inner ring, need to inject lubricant oil, come out, need again on the end face of bearing, seal ring to be set in order to prevent oil leak; The existing bearing seal ring mainly comprises a Steel Bracket and is coated on the rubber ring on the Steel Bracket that rubber ring has sealing words, in the sealing words, has an oil storage chamber; Because the sealing words of rubber material are softer; Easy deformation under the extruding of external force causes the interior lubricant oil of oil storage chamber to external leakage, has influenced the performance of bearing.
The model utility content
For overcoming above-mentioned defective, the utility model aim to provide a kind of seal under the words extruding of power outside not yielding, thereby make the lubricant oil in the oil storage chamber can not guarantee the bearing sealed ring of bearing performance to external leakage.
For achieving the above object; The technological scheme that the utility model adopts is: a kind of bearing sealed ring comprises the ring-type Steel Bracket and is coated on the rubber ring on the Steel Bracket that the outer of said rubber ring is provided with the sealing words; Have oil storage chamber in the said sealing words, be provided with a bracing ring in the said oil storage chamber.
Said bracing ring is a spring ring.
Adopted the bearing sealed ring of the utility model; Owing in the sealing words, be equipped with a bracing ring; Receiving under the extruding of external force when sealing words, bracing ring has a supporting effect, and the sealing words can be out of shape; Thereby make the lubricant oil in the sealing words can not guarantee the performance of bearing to external leakage.
Description of drawings
Fig. 1 is the novel structural representation of this reality.
Among the figure: the 1-Steel Bracket, the 2-rubber ring, 3-seals words, 4-oil storage chamber, 5-bracing ring.
Embodiment
As shown in Figure 1; The utility model discloses a kind of bearing sealed ring, comprise ring-type Steel Bracket 1 and be coated on the rubber ring 2 on the Steel Bracket 1, the outer of said rubber ring is provided with sealing words 3; Has oil storage chamber 4 in the said sealing words 3; Be marked with lubricant oil in the oil storage chamber 4, sealing words 3 are used for the sealing to bearing face, and lubricant oil can not come out from leakage between the inside and outside circle of bearing.In sum, with existing bearing ring structure basically identical.
The innovative point of the bearing sealed ring of the utility model mainly is to be provided with in the said oil storage chamber 4 bracing ring 5.Through the support of 5 pairs of oil storage chambers 4 of bracing ring, make sealing words 3 can not be out of shape down by external force extruding, thereby make sealing words 3 interior lubricant oil can not guarantee the performance of bearing to external leakage.
In bracing ring 5 can easily be packed oil storage chamber 4 into for ease, common said bracing ring 5 can be spring ring.Because spring ring has certain elasticity, operator are packed into bracing ring in the oil storage chamber 4 easily, bracing ring 5 withstands the end face of oil storage chamber 4 on the other hand, makes bracing ring 5 be difficult in oil storage chamber 4, coming off.
Claims (2)
1. bearing sealed ring; Comprise ring-type Steel Bracket (1) and be coated on the rubber ring (2) on the Steel Bracket (1); The outer of said rubber ring is provided with sealing words (3); Have oil storage chamber (4) in the said sealing words (3), it is characterized in that being provided with in the said oil storage chamber (4) bracing ring (5).
2. bearing sealed ring according to claim 1 is characterized in that said bracing ring (5) is a spring ring.
