Wear member assembly with collared fastening assembly
A fastening assembly may comprise a collar and a pin. The collar may have an aperture, a collar lock, which projects from an outer surface, and a pin lock, which is disposed on a portion of the aperture. The collar lock may be compressible and configured to elastically deform while introducing the collar to a wear member. The pin may have a pin lock engagement hole shaped to engage with the pin lock as it is inserted through the aperture of the collar. The fastening system may be used in a wear member assembly. The wear member may have a side opening in communication with a cavity formed on one end of the wear member. The side opening may have a collar lock engagement hole. The collar may be inserted into the side opening so that the collar lock engages the collar lock engagement hole. Methods and assemblies thereof.
1 . A fastening assembly for securing a wear member, comprising:
a collar having an exterior surface, comprising:
an aperture;
a lock holding recess in the exterior surface;
a collar lock coupled to the lock holding recess and projecting from the exterior surface of the collar, the collar lock being elastically deformable inward while introducing the collar to a wear member and engageable with a collar lock engagement hole in an opening of the wear member to hold the collar within the opening of the wear member, wherein the collar lock comprises:
an elastic base coupled to the lock holding recess; and
a head coupled to the elastic base such that the head projects at least partially outwardly beyond the exterior surface of the collar; and
a pin lock disposed on a portion of the aperture; and
a pin shaped to be inserted into the aperture of the collar, the pin having a pin lock engagement hole shaped to engage with the pin lock.
2 . The fastening assembly of claim 1 , wherein the collar comprises a projection forming a part of the exterior surface, the projection having a surface angled relative to a longitudinal axis at a different angle than an opposing portion of the exterior surface.
3 . The fastening assembly of claim 2 , wherein the collar comprises a first collar lock located on a first side of the projection and a second collar lock located on a second side of the projection.
4 . The fastening assembly of claim 2 , wherein a height of the collar at the projection is greater than a height of the opposing portion of the exterior surface.
5 . The fastening assembly of claim 2 , wherein the pin lock is aligned with the projection.
6 . The fastening assembly of claim 1 , wherein the exterior surface comprises a flat region, the collar lock being disposed on the flat region.
7 . The fastening assembly of claim 1 , wherein the aperture of the collar is biased towards a leading end of the wear member.
8 . A fastening assembly for securing a wear member, comprising:
a collar configured to be secured in the wear member, the collar having a cavity-facing end, an outwardly facing end, and an outer surface extending between the cavity-facing end and the outwardly facing end, the collar tapering from the cavity-facing end to the outwardly facing end, the collar comprising:
an aperture defining a longitudinal axis;
a lock holding recess in the outer surface;
a collar lock coupled to the lock holding recess and projecting from the outer surface of the collar, the collar lock being elastically deformable inward while introducing the collar to a wear member and engageable with a collar lock engagement hole in an opening of the wear member to hold the collar within the opening of the wear member, wherein the collar lock comprises:
an elastic base coupled to the lock holding recess; and
a head coupled to the elastic base such that the head projects at least partially outwardly beyond the outer surface of the collar; and
a pin lock disposed in the collar and projecting into the aperture, the pin lock comprising a compressible body and a plunger that projects into the aperture; and,
a threaded pin shaped to fit into the aperture, the pin having a pin lock engagement hole for engaging with the pin lock.
9 . The fastening assembly of claim 8 , wherein the collar comprises a projection forming a part of the outer surface, the projection having a surface angled relative to the longitudinal axis at a different angle than an opposing portion of the outer surface.
10 . The fastening assembly of claim 9 , wherein the collar comprises a first collar lock located on a first side of the projection and a second collar lock located on a second side of the projection.
11 . The fastening assembly of claim 9 , wherein a height of the projection is greater than a height of the opposing portion of the outer surface.
12 . The fastening assembly of claim 9 , wherein the pin lock is aligned with the projection.
13 . The fastening assembly of claim 8 , wherein the outer surface comprises a flat region, the collar lock being disposed on the flat region.
14 . The fastening assembly of claim 9 , wherein the aperture of the collar is biased towards a leading end of the wear member.
15 . The fastening assembly of claim 8 , wherein the collar is asymmetrical about the longitudinal axis.
