ている。[Detailed Description of the Invention] This invention relates to a plastic cage for spherical roller bearings. Conventionally, a plastic cage for a spherical roller bearing is known, for example, as shown in FIG. 1, as proposed in British Patent Publication No. 2049837.
すなわち、２つの環状部材である第１環状部１

し、かつ前記２つの環状部を連結するウエブ３ａ
を含んでおり、前記２つの環状部材を軸方向にみ
たとき、その投影が重ならないようになつてい
る。 That is, the first annular part 1 which is two annular members
a, a web 3a forming a pocket surface 31a with the second annular portion 2a, and connecting the two annular portions.
When the two annular members are viewed in the axial direction, their projections do not overlap.
いわゆる軸方向に金型を引抜くアキシヤルドロ
ー方式で成型加工が出来るようにポケツト成形型
の合せ面Saがころ４ａの中心Oaを通るようにな
つている。 The mating surface Sa of the pocket mold passes through the center Oa of the roller 4a so that molding can be performed by the so-called axial draw method in which the mold is pulled out in the axial direction.
この場合、第１環状部１ａは前記合せ面より外
側につて、ころ頭部４１ａ（第１図ころ左側の端
面）の案内用であり、第２環状部２ａは前記合せ
面より内側にあつて、ころ尾部４２ａ（第１図こ
ろ右側の端面）の案内用である。 In this case, the first annular portion 1a is located outside the mating surface for guiding the roller head 41a (the left end surface of the roller in Figure 1), and the second annular portion 2a is located inside the mating surface. , for guiding the roller tail portion 42a (the end surface on the right side of the roller in Figure 1).
そして、保持器の強度を高く維持することと、
ころ４ａを確実に案内する目的で前記２つの環状
部は出来る限り断面を大きく、かつウエブの断面
高さＨも大きくしなければならない。 In addition, maintaining the strength of the cage at a high level,
In order to reliably guide the rollers 4a, the two annular portions must have as large a cross section as possible, and the cross-sectional height H of the web must also be large.

R1a，R2aに応力が集中し、繰りかえし荷重によ
つて疲労破壊が生ずる可能性を有していた。 A problem caused by such a rigid shape is that the cage becomes heavy, and when the bearing rotates, it restricts the rotation and revolution of the rollers 4a, causing slippage between the outer diameter parts of the orbit (not disclosed), and as a result. smearing is more likely to occur. In addition, since the cross section is made larger and the rigidity is increased, when a load is applied, the joint point connecting the two annular parts and the web
Stress was concentrated at R 1a and R 2a , and there was a possibility that fatigue failure would occur due to repeated loading.
この考案は上記の欠点を解消するためになされ

転を妨げない軽量型の球面ころ軸受用保持器を提
供することにある。 This invention was made to eliminate the above-mentioned drawbacks, and the purpose of this invention is to provide a lightweight and high-strength plastic cage for spherical roller bearings. An object of the present invention is to provide a lightweight cage for a spherical roller bearing that does not hinder the rotation of the bearing.
次にこの考案の実施例について図面を参照して

斜視図である。 Figures 2 and 3 show an embodiment of this invention, and Figure 2 shows a structure in which spherical rollers 4 are interposed between an inner raceway ring and an outer raceway ring (not disclosed), and the rollers are held by a cage. FIG. 3 is a sectional view of the main part showing a state in which the main part is in a state where the main part is in a sectional view, and FIG. 3 is a perspective view of the main part.

いる。 Further, 5 is an annular space existing between the outer annular part 21 and the inner annular part 22, and when the first annular part and the second annular part are projected and overlapped in the axial direction, One annular portion enters the annular space, and an axial draw connects the inner circumferential portion of the outer annular portion 21 and the outer circumferential portion of the first annular portion, and the outer circumferential portion of the inner annular portion and the inner circumferential portion of the first annular portion. Mold surfaces S 1 and S 2 (parting line) that enable this method
exists. Further, the web has a suitable cross-sectional height H so as to hold the roller 4 in a sufficiently stable state.

1, and the outer annular portion 21 of the second annular portion is close to the outer raceway surface side portion B of the connecting portion with the roller outer diameter and tail portion 42. It exists in the part where

のである。 Further, since the outer circumference of the inner annular portion 22 is less than or equal to the inner circumference of the first annular portion to enable axial draw molding, there is no space between the outer annular portion and the inner annular portion. An annular space is inevitably created. As a result, each annular part can have a small cross section, so it is highly elastic, and when a load is applied, the joint between the web and the annular part
The stress concentration at R 1 and R 2 is alleviated to increase fatigue strength, and since the annular space is formed, it becomes a lightweight cage and does not restrict the rotation and revolution of the rollers, reducing smearing and slipping. did not occur,
Furthermore, since the cross sections of the first annular portion, the outer annular portion, and the inner annular portion are small, it also has the effect of facilitating the supply of lubricant to the end faces of the rollers, where it is difficult for lubricant to reach conventionally.

い。 Next, FIG. 4 shows another embodiment of the present invention, in which reference numerals are given in contrast to FIG. 2 and detailed explanation is omitted. When the second annular part 2, which is composed of an annular part 11 and an inner annular part 12 and guides the roller tail part 42, is one annular part and the first annular part and the second annular part are overlapped in the axial direction, the outer The second annular part is arranged to enter the annular space 5 existing between the annular part and the inner annular part, making it possible to perform axial draw molding. It goes without saying that this embodiment also has the same effects as the embodiments shown in FIGS. 2 and 3.
