摘要： The present invention provides an improvement for use in a machine tool having a spindle (51) mounted in a body opening (30) for axial and rotative movement relative to a body (31). The improvement includes a bearing assembly (25) that permits spindles (S1, S2, S3, . . . ) to be quickly exchanged while obviating the need to recenter a replacement spindle with respect to the opening after the original spindle has been initially center therein. The improved bearing assembly (25) broadly includes: a ferrous tubular sleeve (29) mounted in the body opening, the sleeve having an outer surface (40) arranged to face toward a portion (31) of the body that surrounds the opening and having an inner surface (36, 39) arranged to face toward a penetrant portion of the spindle; and a tubular bearing (46) arranged within the sleeve, the tubular bearing having an outer surface (51) arranged to face the sleeve inner surface and having an inner surface (50) arranged to face the spindle penetrant portion.
摘要翻译：本发明提供了一种用于机床的改进，所述机床具有安装在主体开口（30）中以相对于主体（31）进行轴向和旋转运动的主轴（51）。该改进包括允许快速更换锭子（S1，S2，S3）的轴承组件（25），同时避免在原始主轴已经被关闭之后相对于开口更换更换主轴的需要最初居中。改进的轴承组件（25）广泛地包括：安装在主体开口中的铁质管状套管（29），套筒具有设置成面向主体的围绕开口的部分（31）的外表面（40），并且具有布置成面向主轴的渗透部分的内表面（36,39）; 以及布置在所述套筒内的管状轴承（46），所述管状轴承具有布置成面向所述套筒内表面并且具有布置成面向所述心轴渗透部分的内表面（50）的外表面（51）。
