  • the transverse dimension of the spigot portion is a distance between opposed sidewalls thereof.
  • FIG 2B shows a rear perspective view of the tooth shown in FIG 2A
  • FIG 10A shows a sectional top view of the lock assembling in the locked position with a keeper associated therewith
  • FIG 10B shows a perspective view of the excavator wear assembly shown in FIG 1A;
  • Spigot portion 1230 also has a retaining passage 1237 extending therethrough between opposed side walls 1236 thereof.
  • Lock assembly 1300 comprises a locking pin 1310, a biasing member 1320, a retaining member 1330, a keeper 1340 and a compression washer 1350.
  • Lock assembly further comprises a pair of washers 1301 , 1302 adapted to locate against opposed faces of biasing member 1320.
  • annular ridge 1322 of biasing member 1320 is located within annular valley 1337 of retaining- member 1330 such that biasing member 1320 is securely located within cavity 1334.
  • a load scenario of this nature places a large force on the mounting ears 1 103,1 104 giving rise to the possibility that the ears 1103,1 104 may fail through cracking and the like.
  • the possible consequence of having an mounting ear 1 103,1104 crack is that the tooth 1100 may prematurely detach from the adaptor 1200.
  • each mounting ear 1 103,1 104 being one third the transverse dimension B of the socket cavity 1 1 10 as being most advantageous in mitigating failure in the mounting ears 1 103, 1104.

Abstract

L'invention concerne un ensemble d'usure comprenant un adaptateur comportant une partie ergot. La partie ergot possède une dimension transversale. L'ensemble d'usure comprend également un élément d'usure monté de manière amovible sur l'adaptateur. L'élément d'usure comprend un corps avec une cavité de prise, et la cavité de prise est conçue pour recevoir la partie ergot de l'adaptateur. L'élément d'usure comprend également une paire de lobes de montage s'étendant depuis le corps. Chacun des lobes de montage possède une dimension transversale. La dimension transversale de chaque lobe de montage représente de 0,25 à 0,4 fois la dimension transversale de la partie ergot.
