    • A mounting device (21, 22, 23) for anchoring a machine element (11) coaxially on a rotary shaft (12). The device fits between the machine element and the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft. The device has similarly tapered inner (21) and outer (22) segmented sleeves, so that relative axial displacement of the sleeves effects radial expansion and contraction of the combined elements. At one end (29) the inner sleeve cooperates with a nut (23) to effect the axial displacement of the sleeves. The outer sleeve has separate segments (36) coupled with said nut to permit limited pivotal movement of the segments. In another embodiment (Fig. 6), the sleeves (121, 122) are constructed to avoid relative rotation between the sleeves by a locking portion (146). In a third embodiment (Fig. 9), the inner sleeve (221) also has separable segments (226) and a tubular element (260) which are interconnected similarly to the interlocking of the outer sleeve segments with the nut. Improved performance is provided (Fig. 10) by providing anti-friction bearing elements (350) between the nut (323) and the outer sleeve (321) and anti-friction screw threads (338) between the nut (323) and the inner anti-friction coating (450) may be applied to the nut (425).
    • 一种用于将机器元件(11)同轴地固定在旋转轴(12)上的安装装置(21,22,23)。 该装置安装在机器元件和轴之间,并且有效地将元件定位在轴的纵向和轴的任何角度位置的任何所需位置处。 该装置具有类似的锥形内部(21)和外部(22)分段的套筒,使得套筒的相对轴向位移影响组合元件的径向膨胀和收缩。 在一端(29),内套筒与螺母(23)配合以实现套筒的轴向位移。 外套筒具有与所述螺母联接的分离段(36),以允许段的有限枢转运动。 在另一个实施例(图6)中,套筒(121,122)被构造成通过锁定部分(146)避免套筒之间的相对旋转。 在第三实施例(图9)中,内套筒(221)还具有可拆卸的段(226)和管状元件(260),其类似于外套管段与螺母的互锁。 通过在螺母(323)和外套筒(321)之间提供抗摩擦轴承元件(350)和在螺母(323)和内套筒(321)之间的抗摩擦螺纹(338),提供了改进的性能(图10) 可以将抗摩擦涂层(450)施加到螺母(425)上。
