Hereinafter, embodiments of this invention will be described based on the accompanying drawings. In the first embodiment of the present invention shown in FIG. 1, a core bar 22 installed in an annular groove 21 formed at the end of an outer ring 20 has an inner core bar 23 and an outer core bar 24. They are fixed together by spot welding. The seal lip 25 made of woven fabric is sandwiched between the two core metals 23 and 24 at its outer circumference, and its inner circumference 2
6 is in sliding contact with a step 28 formed at the end of the inner ring 27. This stepped portion 28 can be provided with an inclined surface 29 at an appropriate angle to change the tension force with the seal lip 25, and also prevents deterioration of sealing performance due to a gap with the seal lip 25 caused by dimensional errors during assembly. can. Note that the seal lip 25 may be made of a porous material other than woven fabric depending on the purpose. For example, felt and wire mesh are suitable. In order to reinforce the seal lip 25, the inner edge 30 of the inner core bar 23 is extended to the vicinity of the outer diameter of the inner ring 27, and the seal lip 2 is prevented from colliding with dust, iron pieces, etc.
5. Prevents rolling. This inner core metal 23
Numerous small through holes 31 are formed in the bearing in order to allow more of the clean oil that has passed through the seal lip 25 to penetrate into the bearing. In order to more firmly hold the seal lip 25, it is preferable to bring the burrs generated when forming the through hole 31 to the seal lip 25 side. Furthermore, it is preferable that the inner edge 30 of the inner core bar 23 be formed at an acute angle so that the seal lip 25 can be inserted into the inner edge 30 of the inner core bar 23. FIG. 2 shows a second embodiment of the present invention, in which a core bar 32
is composed of one member. The inner edge 33 of this core metal 32 has seal lips 25 at several locations around the circumference.
A holding bent portion 34 is formed. The rest of the configuration is the same as that of the first embodiment, so a description thereof will be omitted.
以上のような構成にしたので、下記のような効
果を有する。
(イ) 内方側芯金の内縁を内輪外径近傍まで延ばし
たので、シールリツプの腰が強くなり、使用中
或いは組み込み中にまくれ込むことはない。
(ロ) 内方側芯金の補強部に多数の貫通孔を形成し
たので、フイルターシールを通過した清浄な油
が軸受内部に浸透するのを阻害しない。
With the above configuration, the following effects are achieved. (a) Since the inner edge of the inner core bar is extended to near the outer diameter of the inner ring, the seal lip is strong and will not curl up during use or installation. (b) Since a large number of through holes are formed in the reinforcing portion of the inner core metal, clean oil that has passed through the filter seal will not be obstructed from penetrating into the inside of the bearing.
