Abstract
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.
