摘要： A rotor coupling (1) for connecting a graphite rotor (37) to a drive shaft (12) of a rotary degassing machine comprises a cap (2) which fits over an end of the rotor and contains gripping means (3, 4) to retain the rotor in the cap. The arrangement avoids screw-threaded interconnection between the rotor and drive shaft which necessitates the forming of a screw-thread on the rotor, adds to the cost of rotor manufacture, and quickly wears with use. No, or minimal, special forming of the rotor is needed for engagement by the gripping means. A used rotor which has a worn or broken screw-thread may be held by the gripping means for the rotor to have further useful service. The gripping means preferably comprises two collet-form sleeves (3, 4) which fit one within the other inside the cap and have complementary tapered surfaces (22, 23) which co-operate upon relative axial movement of the sleeves, by means of screws or bolts (27), to cause the inner sleeve (3) to be compressed about the rotor to clamp it to the cap.
摘要翻译：用于将石墨转子（37）连接到旋转脱气机的驱动轴（12）的转子联轴器（1）包括盖子（2），该盖子（2）装配在转子的一端并包含夹紧装置（3,4）将转子保持在盖中。该装置避免了转子和驱动轴之间的螺纹连接，这需要在转子上形成螺纹，增加了转子制造的成本，并且在使用时迅速磨损。不需要或最小的特殊形状的转子需要通过夹持装置的接合。具有磨损或破损的螺纹的使用过的转子可以由用于转子的夹持装置保持以具有进一步的有用的服务。夹持装置优选地包括两个夹头形式的套筒（3,4），所述夹套形式的套筒（3,4）在帽子的另一内侧安装，并且具有互补的锥形表面（22,23），其通过套筒的相对轴向移动或螺栓（27），以使内套筒（3）围绕转子被压缩以将其夹紧到盖子上。
