Title (EN) ROLLING BEARING AND PRODUCTION PROCESS THEREFOR
(FR) PALIER À ROULEMENT ET SON PROCÉDÉ DE PRODUCTION
(JA) 転がり軸受及びその製造方法
Abstract:
(EN) A rolling bearing comprising an outer ring having an outer circumferential surface where the outer ring is fitted into a housing and an inner ring having an inner circumferential surface where a shaft is fitted into the inner ring, the outer or inner circumferential surface having a burned film comprising an organic binder, a solid lubricant powder such as a molybdenum disulfide powder, and a friction/wear modifier such as an antimony oxide powder. This rolling bearing has better creep resistance without arousing a cost or size increase or suffering a deformation or softening.
(FR) La présente invention concerne un palier à roulement comprenant une bague externe ayant une surface circonférentielle externe où la bague externe est ajustée dans un boîtier et une bague interne ayant une surface circonférentielle interne où un arbre est ajusté dans la bague interne, la surface circonférentielle externe ou interne comportant un film gravé comprenant un liant organique, une poudre de lubrifiant solide telle qu’une poudre de disulfure de molybdène, et un modificateur de frottement/usure tel qu’une poudre d’oxyde d’antimoine. Ce palier à roulement présente une meilleure résistance au fluage sans entraîner une augmentation de coût ou de taille ou souffrant d’une déformation ou d’un ramollissement.
(JA) ハウジングとの嵌合面である外輪の外径面、又は軸との嵌合面である内輪の内径面が、有機バインダーと、二硫化モリブデン粉末等の固体潤滑剤粉末と、酸化アンチモン粉末等の摩擦摩耗調整剤とを含む焼成膜を有する転がり軸受。この転がり軸受は、コスト増やサイズアップ、軸受の変形や軟化を生じることなく、耐クリープ性能により優れたものとなる。
