Title (EN) ANGULAR BALL BEARING
(FR) ROULEMENT À BILLES À CONTACT OBLIQUE
(JA) アンギュラ玉軸受
Abstract:
(EN) Provided is an angular ball bearing having excellent lubrication characteristics in a guiding surface of a holding implement, in which noise can be minimized. An angular ball bearing 1 is provided with an inner race 2 and an outer race 3 which are bearing races, a plurality of balls 4 placed between the inner and outer races, and a holding implement 5 for holding the balls 4. A lubricant is supplied to or sealed in an internal space of the bearing, the holding implement 5 has a flocked part 6 guided by the outer race 3 and made by flocking fibers at least on an outer race guiding surface 5d of the holding implement 5, the fibers are synthetic resin fibers, and the flocked part 6 is an electrostatic flocked part.
(FR) L'invention concerne un roulement à billes à contact oblique ayant d'excellentes caractéristiques de lubrification dans une surface de guidage d'un système de retenue, dans lequel le bruit peut être réduit au minimum. Un roulement à billes à contact oblique (1) est pourvu d'une bague intérieure (2) et d'une bague extérieure (3) qui sont des chemins de roulement, d'une pluralité de billes (4) placées entre les bagues intérieure et extérieure, ainsi que d'un système de retenue (5) pour retenir les billes (4). Un lubrifiant est introduit dans un espace interne du roulement ou scellé dans celui-ci, le système de retenue (5) a une partie floquée (6) guidée par la bague externe (3) et constituée par des fibres de flocage au moins sur une surface de guidage (5d) de bague externe du système de retenue (5), les fibres sont des fibres en résine synthétique et la partie floquée (6) est une partie floquée électrostatique.
(JA) 保持器の案内面での潤滑特性に優れ、異音の発生を抑制できるアンギュラ玉軸受を提供する。アンギュラ玉軸受1は、軌道輪である内輪2および外輪3と、この内・外輪間に介在する複数の玉4と、玉4を保持する保持器5とを備え、軸受内空間に潤滑剤が供給または封入され、保持器5は、外輪3に案内され、少なくとも保持器5の外輪案内面5dに繊維を植毛してなる植毛部6を有し、この繊維が合成樹脂繊維であり、植毛部6が静電植毛部である。
