BEARING EQUIPPED WITH HOLDER

PROBLEM TO BE SOLVED: To provide a holder of a bearing which has a lubricating oil storage structure.SOLUTION: A bearing equipped with a holder includes: an inner ring 1; an outer ring 2 covering an outer periphery of the inner ring; a plurality of rolling bodies 4; and an annular holder 3. The inner ring has a rolling groove 11, and the outer ring has a rolling groove 21 installed oppositely to the rolling groove of the inner ring. The rolling groove of the inner ring and the rolling groove of the outer ring configures a load path. The holder is provided with a plurality of storage holes 31 for installing the rolling bodies. Each storage hole is composed of a plurality of corresponding U-shaped half holding portions 311. U-shaped openings 3111 of the two half holding portions oppositely installed are installed while intersecting. The two half holding portions are provided with corresponding U-shaped half oil grooves 312A and 312B, respectively. The two half oil grooves constitute one oil groove, and a lubricating oil storage space is formed between the rolling bodies and the oil grooves.SELECTED DRAWING: Figure 3 【課題】潤滑油貯留構造を有する軸受の保持器を提供。【解決手段】内輪１と、内輪の外周に套設する外輪２と、複数の転動体４と、環状の保持器３と、を含み、内輪は転動溝１１を有し、外輪は内輪の転動溝と対向して設置される転動溝２１を有し、内輪の転動溝と外輪の転動溝とが負荷経路を構成し、保持器には転動体を設置するための複数の収容孔３１が設けられ、各収容孔は複数の対応するＵ字形状の半保持部３１１によって構成され、対向して設置される二つの半保持部のＵ字形状の開口３１１１は交錯して設置され、二つの半保持部には対応するＵ字形状の半油溝３１２Ａ，３１２Ｂがそれぞれ設けられ、二つの半油溝は一つの油溝を構成し、転動体と油溝との間に潤滑油貯留空間が形成される。【選択図】図３
