Title
(EN) SCROLL COMPRESSOR
(ZH) 涡旋式压缩机
Abstract
(EN) The present invention relates to a scroll compressor which may comprise: a first bearing for rotatably supporting a rotation shaft on a casing on one side of a motor; a second bearing for rotatably supporting the rotation shaft on the casing on the other side of the motor; and a third bearing for rotatably supporting the rotation shaft on an orbiting scroll on the opposite side to the first bearing with reference to the second bearing, wherein the distance between the center of the first bearing and the center of the third bearing is defined by a predetermined distance, the distance between the center of the motor and the center of the third bearing is defined by a longer distance than the distance between the center of the motor and the center of the first bearing, and the distance between the center of the second bearing and the center of the motor is defined by a longer distance than the distance between the center of the second bearing and the center of the third bearing. Accordingly, the second bearing which is placed in poor load conditions can be prevented from being damaged.
(ZH) 本发明涉及涡旋式压缩机,上述涡旋式压缩机包括:第一轴承,以上述马达为基准,在一侧,相对于上述外壳以可旋转的方式支撑上述旋转轴;第二轴承,以上述马达为基准,在另一侧,相对于上述外壳以可旋转的方式支撑上述旋转轴;以及第三轴承,以上述第二轴承为基准,在上述第一轴承的相反侧,相对于上述回旋涡旋盘以可旋转的方式支撑上述旋转轴,第一轴承中心与第三轴承中心之间的距离为预先确定的距离,马达中心与第三轴承中心之间的距离大于马达中心与第一轴承中心之间的距离,第二轴承中心与马达中心之间的距离大于第二轴承中心与第三轴承中心之间的距离。由此,可防止因负荷条件差而产生的第二轴承的破损。
