    • Coupling assemblies for releasably holding separable parts together, and in particular for releasably securing a wear member to a support structure in excavating equipment are formed so as to provide increased take up to ensure a tight fit of the wear member on the support structure even if considerable deviation between the parts exists due to wearing, manufacturing variations or the like. The coupling assemblies are suitable for securing points, adapters, shrouds, or other replaceable component to various excavating equipment. The components of the coupling assembly include a wedge and a spool that pivots about a fulcrum when the wedge is driven into assembly for increased take up capabilities. The spool is rotatably engaged around a fulcrum of the support structure and has a bearing portion that bears against and moves the wear member to be secured to thereby take up any gaps between the engaging surfaces of these members. A movable insert may be provided to improve the cooperation between the wedge and the spool to further increase the available take up.
    • 形成用于可拆卸地将可分离部分保持在一起的联接组件,特别是用于将耐磨件可释放地固定到挖掘设备中的支撑结构,以便提供增加的卷取,以确保磨损构件紧紧地配合在支撑结构上,即使相当可观 零件之间的偏差由于磨损,制造变化等而存在。 联接组件适合于将点,适配器,护罩或其他可替换部件固定到各种挖掘设备。 联接组件的部件包括楔形件和当楔形件被驱动到组件中时绕支点枢转的卷轴,以增加卷取能力。 阀芯可旋转地接合在支撑结构的支点周围,并且具有支承部分,该轴承部分抵靠并移动要被固定的磨损构件,从而占据这些构件的接合表面之间的任何间隙。 可以提供可移动的插入件以改善楔形件和卷轴之间的配合,以进一步增加可用的卷绕。
