Abstract

PURPOSE:To prevent strain of the bent-edge part, which occurs when a bent- edge sealing member for a ball bearing is caulked into a sealing groove of the outer race, by making a required number of holes along the bent-edge part of the said sealing member. CONSTITUTION:Holes 1 are drilled at a constant interval in the bent part 3 of a bent-edge part 2. As a result, when a sealing member is caulked into the sealing groove 5 of an outer race 4, the bent-edge part 2 is fitted into the sealing groove 5 in such a state that the peripheral piece 7 of the bent-edge part 2 is bent inward. However, the strain, which occurs at the bent-edge part 2 in such a state as described above, is absorbed by the holes 1 of the bent-edge part 2, thereby ensuring proper sealing.

著である。(Problems to be Solved by the Invention) However, the conventional ear-curved seal member for ball bearings is
Since it has the shape and structure as shown in FIG. 3, it has the disadvantage that when it is caulked into the sealing groove of the outer ring, the bent portion of the ear is distorted and the seal cannot be properly sealed. This drawback is particularly noticeable in stainless steel ball bearing seal members.

そこで、この発明は前記の従来の欠点を解決することを
目的として提案するものである。Therefore, the present invention is proposed for the purpose of solving the above-mentioned conventional drawbacks.

), and the holes (1) are bored in odd numbers at predetermined intervals in the bent part (31). In the figure, (4) is the outer ring, and (5) V'i is the outer ring. (4) is a sealing groove, and (6) is a groove for a ball (not shown).The curved seal member for a ball bearing in the embodiment is made of stainless steel.Furthermore, in this invention, The shape of the hole (1) is not limited, and it goes without saying that it can be formed in any shape.
