摘要: Object: In a scroll type fluid machine in which a swivel scroll (14) is driven by a drive bush (101) engaged with a drive shaft bearing portion of said swivel scroll (14) and an eccentric drive pin (25) provided eccentrically on a drive shaft (7), a concentrated surface fatigue caused on the surface of the drive bush (101) is avoided and an elongation of the life of the drive bush (101) is attained.
Construction: A rotatable cylindrical ring (102) is provided on the outer circumference of the drive bush (101).摘要翻译: 目的:在一个涡旋式流体机械中,一个旋转涡旋件(14)由一个与所述旋转涡旋件(14)的驱动轴承部分啮合的驱动轴套(101)和一个偏心驱动销(25) 驱动轴(7)避免了在驱动衬套(101)的表面上产生的集中表面疲劳,并且延长了驱动衬套(101)的使用寿命。 构造:在驱动衬套(101)的外圆周上设置有可旋转的圆柱形环(102)。
