Benefits of technology

The present invention relates to anti-tipping retainers and tip assemblies. The technical effects of this invention include improved prevention of tipping and better stability of the components in tip assemblies. The anti-tipping retainers have a lug receiving portion with a maximum outside dimension and a lug receiving slot that extends partially through the receiving portion. A drive portion also has a maximum outside dimension, and a detent receiving surface is disposed on the outside of the lug receiving portion. The drive portion also includes a tab with a stopping surface. The tip assembly has a body with a forward working portion and a rear attachment portion, and an anti-tipping retainer is disposed in the retaining mechanism receiving aperture. The retaining mechanism receiving aperture has a counterbore with a maximum diameter and a thru-hole with a minimum diameter. The anti-tipping retainer has an arcuate bearing surface that is disposed along the counterbore longitudinal axis, which helps to prevent tipping of the components.

Problems solved by technology

During the locking and unlocking of the retainer, the retainer may become undesirably cocked or tipped.

Embodiment Construction

[0019]Reference will now be made in detail to embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In some cases, a reference number will be indicated in this specification and the drawings will show the reference number followed by a letter for example, 100a, 100b or a prime indicator such as 100′, 100″ etc. It is to be understood that the use of letters or primes immediately after a reference number indicates that these features are similarly shaped and have similar function such as is often the case when geometry is mirrored about a plane of symmetry. For ease of explanation in this specification, letters or primes will often not be included herein but may be shown in the drawings to indicate duplications of features discussed within this written specification.

Abstract

An anti-tipping retainer has a lug receiving portion defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion has recess for turning the retainer. At least a first detent receiving surface is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall. The drive portion further includes a tab that has a bearing surface extending between a first stop surface and a second stop surface.

Description

TECHNICAL FIELD[0001]The present disclosure relates to retaining mechanisms employed on work implement assemblies such as bucket assemblies used by earth moving, mining, construction equipment and the like for attaching a tip to an adapter of the work implement assembly. More specifically, the present disclosure relates to an anti-tipping retainer used in such retaining mechanisms that may be less prone to becoming cocked or tipped in the tip.BACKGROUND[0002]Machines such as wheel loaders, excavators, and the like employ work implement assemblies including bucket assemblies, rakes, shears, etc. that have teeth or tips attached to them to help perform work on a material such as dirt, rock, sand, etc. For example, teeth or tips may be attached to a bucket assembly to help the bucket assembly to penetrate the ground, facilitating the scooping of the dirt into a bucket. Adapters are often attached to the work edges (e.g. the base edge, the side edge, etc.) of the bucket or other work im...
