本考案は軸とハウジング等の相対回転する二部
材間に用いられるベアリングの密封装置に関し、
さらに具体的にはベアリングシールとフリンガー
からなるユニツトベアリングシールに関するもの
である。[Detailed description of the invention] [Field of industrial application] The present invention relates to a sealing device for a bearing used between two relatively rotating members such as a shaft and a housing.
More specifically, it relates to a unit bearing seal consisting of a bearing seal and a flinger.

Unit bearings used in the front wheel bearings of front wheel drive vehicles are required to have high sealing performance due to the location where they are used, and various improvements have been made. The sealing effect has not yet been guaranteed.

However, the axial lip 1 that comes into contact with the flinger 7 attached to the drive shaft 4 as described above is connected to the drive shaft 4 and the bearing 2.
Due to mounting errors between the bearings 2 and the drive shaft 4, or cumulative movement due to external loads after assembly, the tightening of the axial lip 1 may be excessive or weak, which may adversely affect the sealing characteristics. There is a danger that it can pose. If this interference is excessive, the amount of wear on the axial lip 1 will increase and long-term sealing will not be guaranteed.On the other hand, if the interference is weak, the sealing performance will be easily deteriorated due to vibration or high-speed rotation. It had many drawbacks, such as weakening it.

る。[Means for Solving the Problems] As shown in FIG. 1, the present invention comprises a bearing seal A with an axial lip 1 formed of an elastic body that is attached to a tapered bearing 2, and the bearing seal. A unit bearing seal consisting of a metal flinger 3 in contact with A;
The flinger 3 has a deformed L-shape in cross section with a stepped bottom 5, and surrounds a bearing seal A consisting of a radial lip 6 located within the bearing 2 and an axial lip 1 protruding outward from the end surface of the bearing 2. It is characterized in that it is attached so as to come into contact with the axial lip 1 and the radial lip 6, and the stepped bottom surface 5 engages with the stepped portion of the inner ring of the bearing 2 and the drive shaft 4.

In this way, by attaching the flinger 3 in contact with the axial lip 1 and the radial lip 6 to the bearing 2 and using the sealing device as a unit bearing seal, the following effects are produced.

なつた。 That is, as shown in Fig. 1, the bearing seal A and the flinger 3 can be attached to the inner and outer rings of the bearing 2, which are machined with high precision, without being affected by dimensional errors between the drive shaft 4 and the bearing 2. The flinger 3 is securely fixed, and in particular, since the stepped portion of the stepped bottom surface 5 of the flinger 3 also engages with the drive shaft 4, the axial mounting position is accurately determined, and the relative position of the two members A and 3 is extremely accurately determined. Can be placed. Therefore, the tightness of the axial lip 1 and the radial lip 6 is maintained appropriately, deformation is prevented, and a high sealing force is exhibited for a long period of time. Furthermore, since the flinger 3 surrounds the protruding axial lip 1 and contacts the bearing 2 outside, moisture, foreign matter, etc. are sealed at the contact portion and shaken off at the outer peripheral end of the flinger 3. However, even if a very small amount of moisture infiltrates into the protruding axial lip 1, it will pass through the outwardly protruding axial lip 1 and be released to the outside again by the rotational shaking action of the flinger 3 during operation. The structure is ideal as a sealing material because of the sealing effect on the inside of the radial lip 6 which is shaken off and located further inside.

ユニツトベアリングシールである。 Furthermore, the fact that the axial lip 1 can always maintain an appropriate interference due to the above action means that the bearing seal A
This frees you from the troublesome design work of making the material have flexible elasticity or forming a seal lip with a complicated shape to expand the allowable flexible contact range. Since it can be formed using carefully considered materials, the manufacturing process and manufacturing method have been greatly simplified. [Effects of the invention] As described above, the present invention protects the seal lips 1 and 6 by accurately determining the axial position of the bearing 2 and the flinger 3, and also prevents them from moving against external loads after assembly. , assembly workability,
It is an ideal unit bearing seal with excellent sealing performance and swinging performance.
