APERTURED ARTICLE, INSERTION ARTICLE AND ASSOCIATED SYSTEMS

BACKGROUND OF THE INVENTION
Technical Field

In some aspects, this disclosure relates to an apertured article that can provide both (i) torque bearing, for example, in combination with an object such as a drill bit or live axle that is intended to transfer torque to and/or from the object and which can thereby result in a rotational force directed around an axis of rotation of the object and/or the article, and (ii) act as a bearing or provide bearing support (e.g., to support a bearing), for example, for an apertured article in the form of a wheel connected to a live or dead axle, the apertured article being intended to bear force perpendicular to an axis of rotation of the article. In some aspects, this disclosure relates to an insertion article configured to be inserted into an aperture of the apertured article and optionally having an outer periphery shaped like an inner periphery of the aperture or having the same number of protrusions as an inner periphery of the aperture. In some aspects, this disclosure relates to a combination of the apertured article and an insertion article configured to be inserted into an aperture of the article. In some aspects, this disclosure relates to an interface of the apertured article and an insertion article configured to be inserted into an aperture of the apertured article. In some aspects, this disclosure relates to a system comprising the apertured article, the insertion article, an interface of the apertured article and the insertion article, or any combination thereof, which system can optionally comprise a robot or a component of a robot. Furthermore, in some aspects, this disclosure relates to a system configured so that the apertured article is interchangeable with a substitute apertured article, the insertion article is interchangeable with a substitute insertion article or any combination thereof. In some aspects, this disclosure relates to a system that can be configured for the apertured article to be installed on a live axle or dead axle, and the insertion article can provide at least a portion of the live axle or dead axle.

Description of Related Art

Existing articles or systems for torque bearing or bearing support or that act as a bearing tend to be designed only to either (i) provide torque bearing ability or (ii) provide bearing support or act as a bearing, but not both, especially in the context of interchangeable or modular components. Moreover, some existing articles or systems tend to require components to be bolted onto the articles, for example, bolted onto the face of a wheel, to provide torque transfer, which increases the thickness of an article in one dimension. Other existing articles or system are only compatible with other articles or systems having either a circular exterior cross-section or a polygonal exterior cross-section, for example, a hexagonal exterior cross-section, but not both circular and polygonal exterior cross-sections. These existing articles or systems lack desirable attributes, for example, the ability to be used with a live axle, a dead axle, or a combination thereof; the ability to provide torque transfer, provide bearing support, act as a bearing, or a combination thereof; ease of use; low cost; ease of manufacture; durability; modularity; interchangeability; combinability; or any combination thereof. For example, in some existing devices, different articles or a greater number of different articles are required to achieve desired functionality, which requires more expense and more time exchanging articles to change functionality. As another example, some existing articles or systems are difficult to use, expensive, difficult to manufacture, easily damaged, non-modular, non-interchangeable, non-combinable, incapable of being used to provide a plurality of desired functionalities, or a combination thereof.

Accordingly, existing techniques and associated devices for providing torque transfer, providing bearing support or acting as a bearing have several undesirable characteristics.
