Abstract:
(EN) [Problem] The present invention provides a roller bearing unit for which the weight can be decreased and the durability can be improved. An outer ring core metal (26) that is manufactured from an iron alloy and forms an outer ring (2a) is molded to an outer ring main body (25) manufactured from a synthetic resin containing reinforced fibers or from an aluminum alloy. At the inner circumferential surface of the outer ring core metal (26), outer ring raceway members (27) are fitted into and affixed to mating concave surfaces (30), which are the portions of the inner circumferential surface of the outer ring core metal (26) that are exposed from the outer ring main body (25). A hub core metal (37) that is manufactured from an iron alloy and forms a hub (3a) is molded to a hub main body (36) manufactured from a synthetic resin containing reinforced fibers or from an aluminum alloy. At the outer circumferential surface of the hub core metal (37), inner ring raceway members (38) are fitted onto and affixed to a mating surface (49), which is the portion of the outer circumferential surface of the hub core metal (37) that is exposed from the hub main body (36).
(FR) La présente invention porte sur une unité de roulement à rouleaux pour laquelle le poids peut être diminué et la durabilité peut être améliorée. Un métal de noyau de bague externe (26) qui est fabriqué à partir d'un alliage de fer et qui forme une bague externe (2a) est moulé sur un corps principal de bague externe (25) fabriqué à partir d'une résine synthétique contenant des fibres renforcées ou à partir d'un alliage d'aluminium. A la surface périphérique interne du métal de noyau de bague externe (26), les éléments de chemin de roulement de bague externe (27) sont adaptés dans des surfaces concaves appariées et fixés à celles-ci (30), lesquelles sont les parties de la surface périphérique interne du métal de noyau de bague externe (26) qui sont exposées à partir du corps principal de bague externe (25). Un métal de noyau de moyeu (37) qui est fabriqué à partir d'un alliage de fer et qui forme un moyeu (3a) est moulé sur un corps principal de moyeu (36) fabriqué à partir d'une résine synthétique contenant des fibres renforcées ou à partir d'un alliage d'aluminium. A la surface périphérique externe du métal de noyau de moyeu (37), des éléments de chemin de roulement de bague interne (38) sont adaptés sur une surface appariée (49) et fixés à celle-ci, laquelle est la partie de la surface périphérique externe du métal de noyau de moyeu (37) qui est exposée à partir du corps principal de moyeu (36).
(JA) 【課題】本発明は、軽量化を図り、かつ、耐久性の向上を図ることができる転がり軸受ユニットの構造を実現する。外輪2aを構成する鉄系合金製の外輪芯金26を、強化繊維を含有した合成樹脂製またはアルミニウム系合金製の外輪主体25にモールドする。外輪芯金26の内周面に、外輪軌道部材27を、外輪芯金26の内周面のうちの外輪主体25から露出した嵌合凹面30に内嵌固定する。一方、ハブ3aを構成する鉄系合金製のハブ芯金37を、強化繊維を含有した合成樹脂製またはアルミニウム系合金製のハブ主体36にモールドする。ハブ芯金37の外周面に、内輪軌道部材38を、ハブ芯金37の外周面のうちのハブ主体36から露出した嵌合面49に外嵌固定する。
