Abstract

A hammerless connector pin assembly is insertable in the aligned connector openings in telescoped ground engaging wear and support members and is releasably lockable therein. The inserted assembly has opposite end portions that block removal of the wear member from the support member. Each of the two end portions has a laterally projecting cam member disposed thereon which is positioned within opposite ones of the two opposed wear member connector openings. As the interior surface of the wear member becomes worn from use and is able to shift further rearwardly along the support member, the cam members may simultaneously be rotationally adjusted to maintain contact with the wear member to prevent forward movement thereof away from its rearward shifted position, and then locked in their rotationally adjusted positions.

Claims22

Dependent claims

Ground engaging apparatus comprising:

a connector pin assembly for captively retaining a wear member on a support member onto which the wear member is telescoped, the support member having a connector opening extending therethrough, said connector pin assembly including:
a tubular sleeve member longitudinally insertable into the connector opening, said sleeve member having an interior surface portion and being configured to be rotationally locked in said connector opening;
first and second longitudinal pin sections, at least one of which having a surface portion engageable with said interior surface portion of said sleeve member, said pin sections having inner end portions longitudinally insertable into opposite ends of said sleeve member in a manner positioning outer end portions of said pin sections externally of said opposite ends of said sleeve member, said outer end portions having laterally outwardly projecting eccentric configurations, said inner end portions of said pin sections being interlockable with one another, in response to insertion into said sleeve member, in a manner preventing relative rotation between said pin sections and causing said eccentric outer end portions of said pin sections to have identical rotational orientations relative to said sleeve member;
and
tightening structure for selectively tightening and loosening the engagement between said surface portions of said sleeve member and said at least one pin section to respectively prevent and permit conjoint rotation of the interlocked pin sections relative to said sleeve member.

2 more elements

Ground engaging apparatus comprising:

a support member through which a connector opening extends;
a hollow wear member rearwardly and removably telescoped onto said support member and having first and second opposed wall openings generally aligned with opposite ends of said connector opening;
and
a connector pin assembly captively retaining said wear member on said support member, said connector pin assembly including:
a tubular sleeve member longitudinally extending through said connector opening and being rotationally locked therein, said sleeve member having an interior surface area,
a pin structure having a surface area, said pin structure longitudinally extending through said tubular sleeve and having outer end portions of laterally eccentric configurations disposed in said wear member wall openings and being locked to one another in identical rotational orientations relative to said sleeve member for conjoint rotation, and
tightening structure operative to selectively (1) forcibly engage said surface areas of said sleeve member and said pin structure in a manner locking said pin structure in said sleeve member, or (2) loosen the engagement between said surface areas of said sleeve member and said pin structure to permit conjoint rotational adjustment of said laterally eccentric outer end portions of said pin structure.
