Abstract
(EN)
A bearing assembly, a rotor assembly and a fan, wherein the bearing assembly (1) comprises: a bushing (14), the inner wall thereof being provided thereon with two grooves along the peripheral direction; a shaft (12), the bushing (14) being sleeved on the shaft (12), the shaft (12) being provided thereon with channels that correspond to each groove among the two grooves, and the channels and the corresponding grooves forming a roller track; and a plurality of rolling bodies (16) which are provided between the shaft (12) and the bushing (14) and which move inside of the roller track, wherein the outer diameter of the bushing is 13 mm, and the diameter of the part at which the shaft and the bushing are provided relative to each other is 5 mm. A fan having the bearing assembly (1) may operate reliably under a rotation speed of at least 150000 rpm.
(FR)
L'invention concerne un ensemble palier, un ensemble rotor et un ventilateur. L'ensemble palier (1) comprend : une douille (14), la paroi interne de la douille étant munie de deux rainures le long de la direction périphérique ; un arbre (12), la douille (14) étant emmanché sur l'arbre (12), l'arbre (12) étant muni de canaux correspondant à chaque rainure parmi les deux rainures, et les canaux et les rainures correspondantes formant un chemin de roulement ; et une pluralité de corps de roulement (16) agencés entre l'arbre (12) et la douille (14) et se déplaçant à l'intérieur du chemin de roulement, le diamètre externe de la douille étant égal à 13 mm, et le diamètre de la partie au niveau de laquelle l'arbre et la douille sont agencés l'un par rapport à l'autre étant égal à 5 mm. Un ventilateur comportant l'ensemble palier (1) peut fonctionner de manière fiable sous une vitesse de rotation d'au moins 150 000 tours/minute.
(ZH)
一种轴承组件、转子组件和风机,轴承组件(1)包括:轴套(14),其内壁上沿周向设置有两个沟槽;轴(12),轴套(14)套设于轴(12)上,轴(12)上设置有与两个沟槽中每一个沟槽相对应的沟道,沟道和对应的沟槽构成滚道;多个滚动体(16),设置于轴(12)和轴套(14)之间并在滚道内运动;其中,轴套的外径为13mm,轴与轴套相对设置的部分的直径为5mm。具有该轴承组件(1)的风机可以在至少150000rpm的转速下可靠地运行。
