Abstract:
(EN) Provided is a hub unit (1) comprising an outer ring (11), a hub wheel (3) (large-diameter part (9)), an inner ring member (12), rolling bodies (14) provided between the outer ring (11) and the hub wheel (3) (large-diameter part (9)) and between the outer ring (11) and the inner ring member (12), and grease (G) disposed on outer ring raceway surfaces (11a, 11b) and inner ring raceway surfaces (13a, 13b), wherein clearance of the rolling bodies (14) with respect to the outer ring raceway surfaces (11a, 11b) and the inner ring raceway surfaces (13a, 13b) is set as negative clearance, and the grease (G) contains: a base oil that is formed of a poly-α-olefin and of which the kinematic viscosity at 40°C is 20-60 mm2/s; a thickening agent including an urea-based compound obtained through a reaction between a diisocyanate compound and a mixed amine of an alicyclic amine and an aromatic amine; and an additive including a phosphite, an ether-based compound, and an oxidized paraffin.
(FR) L'invention concerne une unité de moyeu (1) comprenant une bague externe (11), une roue de moyeu (3) (partie de grand diamètre (9)), un élément de bague interne (12), des corps de roulement (14) disposés entre la bague externe (11) et la roue de moyeu (3) (partie de grand diamètre (9)) et entre la bague externe (11) et l'élément de bague interne (12), et de la graisse (G) disposée sur les surfaces (11a, 11b) de chemin de roulement de la bague externe et les surfaces (13a, 13b) de chemin de roulement de la bague interne, le dégagement des corps de roulement (14) par rapport aux surfaces (11a, 11b) de chemin de roulement de la bague externe et aux surfaces (13a, 13b) de chemin de roulement de la bague interne étant établi comme un dégagement négatif, et la graisse (G) contenant : une huile de base qui est formée d'une poly-α-oléfine et dont la viscosité cinématique à 40°C est de 20-60 mm2/s par seconde; un agent épaississant incluant un composé à base d'urée obtenu par réaction entre un composé isocyanate et une amine mixte d'une amine alicyclique et d'une amine aromatique; et un additif comportant un phosphite, un composé à base d'éther et une paraffine oxydée.
(JA) 外輪(11)、ハブホイール(3)(大径部(9))および内輪部材(12)と、外輪(11)とハブホイール(3)(大径部(9))および内輪部材(12)との間に設けられた転動体(14)と、外輪軌道面(11a,11b)および内輪軌道面(13a,13b)に配置されたグリース(G)とを含み、外輪軌道面(11a,11b)および内輪軌道面(13a,13b)に対する転動体(14)の隙間が負隙間に設定されており、グリース(G)は、ポリαオレフィンからなり、40℃における動粘度20~60mm2/sである基油と、脂環式アミンおよび芳香族アミンの混合アミンと、ジイソシアネート化合物とを反応させて得られるウレア系化合物を含む増ちょう剤と、亜リン酸エステル、エーテル系化合物および酸化パラフィンを含む添加剤とを含有している、ハブユニット(1)を提供する。
