よって正確なころ案内が損われる。Two-material window retainers of this type, in which one edge of the metal plate outer cylinder is bent inward to obtain an L-shaped structural surface, are known (German Patent No. 1159215, German Patent No. 1525153). A plastic comb-shaped retainer is inserted into the metal plate outer cylinder or engaged with it by elastically deformable means. The plastic projections that engage between the rolling elements and extend over the entire length of the rolling elements make it difficult for the lubricant to enter the inside of the bearing, and also prevent the lubricant from entering the bearing interior on the one hand and the plastic projections on the other hand. For reasons of manufacturing technology, it is almost impossible to give the pockets between the pieces the same dimensions. The rolling elements are therefore guided only in the window of the sheet metal sleeve or between relatively long protrusions, which are considered as retainers and are clamped on one side, thereby enclosing the rolling elements in a wide circumferential area. The advantages of the cage are lost and therefore no difference from a simple metal plate cage or a normal cage is obtained. When subjected to vibration, the long free protruding piece is excited and tends to cause natural vibration, so there is a risk of damage. Furthermore, the bending of one edge of the sheet metal sleeve and the configuration of the plastic comb cage result in an asymmetrical cross-sectional shape of the entire cage, which impairs precise roller guidance.
本発明の課題は、これらの欠点を取り除き、そして潤滑
剤が入ることが妨げられず、突片に破損の危険が存在せ
ず、良好な転動体案内が保証されかつ簡単なまたは安価
な製造が可能である、冒頭に述べたよりな２材料窓付き
保持器を提供することにある。The object of the present invention is to eliminate these drawbacks and to provide a structure in which the entry of lubricant is unobstructed, there is no risk of breakage of the projections, good rolling element guidance is ensured and simple or inexpensive manufacture is possible. The object of the present invention is to provide a two-material window holder that is possible to use as described at the outset.
この課題は本発明によれば、互いに軸線方向に間隔を置
いて対向するそれぞれ２つの突片が設けられ、各側の突
片が環により一体化され、この環が端面において金属板
外筒に挿入されまたはこの金属板外筒を包囲することに
よって解決される。This problem can be solved according to the present invention by providing two protrusions facing each other with an interval in the axial direction, and the protrusions on each side are integrated by a ring, and this ring is attached to the metal plate outer cylinder at the end face. The problem is solved by inserting or surrounding this metal plate outer cylinder.
したがって完全に対称的な保持器が得られ、この保持器

損の危険がない。それにも拘らず良好なころ案内が保証
される。なぜならば突片は、所望のなじみ摩耗後に大き
な周囲範囲に亘ってできるだけ遊隙なしに転動体を包囲
するように、難なく調節され得るからである。A completely symmetrical cage is thus obtained, in which only the short tabs engage between the rolling elements, so that there is no risk of breakage of the tabs. Good roller guidance is nevertheless guaranteed. This is because the projection can be adjusted without difficulty so that it surrounds the rolling element over a large circumferential area with as little play as possible after the desired break-in wear.
突片の間の軸線方向間隔は、潤滑剤が入ることを妨げら
れないことを保証する。製造は非常に安くできる。なぜ
ならば切削加工が極く僅かし。The axial spacing between the projections ensures that lubricant entry is unobstructed. It can be manufactured very cheaply. This is because the cutting process is extremely small.

合よりはるかに減少される。This is because it does not occur. The sheet metal sleeve can be cut out of a precision tube or rolled up and welded from a sheet metal strip, and the window can then be punched out of the tube or the sheet metal that has not yet been deformed. Sections with protrusions can be manufactured, for example, with simple injection molding tools. The ring-bearing piece can be constructed from plastic. However, it is also possible to combine it with a steel plate cylindrical projection or a ring made of brass or the like, in which case the manufacturing costs are much lower than in the case of a metal holder.

固定するために、金属板外筒の内面にある環状溝に係合
する。The ring can be pushed into the metal plate sleeve. However, if the ring is of an easily elastically deformable material, the ring can have a ridge on the cylindrical outer surface, which ridge is located on the inner surface of the sheet metal sleeve in order to fix the ring axially. Engages in the annular groove.

。It is of course also possible and often advantageous to provide the annular groove on the annular outer surface and the elevation on the inner surface of the sheet metal sleeve.
本発明によれば、突片は互いに向き合う側からスリット
を切られているので、高い弾性が得られ、僅かな初応力
で正確な転動体案内を保証することができる。According to the present invention, since the protrusions are slit from the sides facing each other, high elasticity is obtained and accurate rolling element guidance can be guaranteed with a small initial stress.
