Earth working bucket and connector assembly securing wear member thereto

摘要

The connector assembly is used in securing a wear member to a support structure of the earth working bucket in an engaged position in which corresponding apertures of the wear member and the support structure are aligned and form a connector passage. The connector assembly is engaged into the connector passage and comprises: an endless screw extending in the connector passage and having an externally operable head, abutment portions facing opposite walls of the connector passage, and a movement transfer mechanism operable to transform rotary movement of the endless screw into a transversal movement of one abutment portion relative the other, to push the abutment portions against corresponding opposite walls of the connector passage.

1. A connector assembly for securing a wear member to a support structure of an earth working bucket in an engaged position in which corresponding apertures of the wear member and the support structure are aligned and form a connector passage, the connector assembly being engageable into said connector passage and comprising:
an endless screw extending in the connector passage, the endless screw having an externally operable head and being free to rotate, trapped and prevented from lengthwise displacement when the connector assembly is engaged in the connector passage, abutment portions facing opposite walls of the connector passage when the connector assembly is engaged in the connector passage, and a movement transfer mechanism operable to transform rotary movement of the endless screw into a transversal movement of one abutment portion relative the other, to push the abutment portions against corresponding opposite walls of the connector passage.
