Elastically Supported Wear Resistant Line Guide and Method of Manufacture

摘要

The disclosed line guides combine a wear resistant ring with a superelastic, shape memory alloy frame and support to provide a lightweight and durable assembly. The wear resistant ring is constructed of hard material such as ceramic. The wear resistant ring includes a groove or annular depression on the outside surface where the ring and frame meet. The elastic frame is configured to grip the ring, which provides an enhanced mechanical connection between the wear resistant ring and the superelastic frame. The groove also provides a location for the application of adhesive. The frame is exposed around the wear resistant ring and protects the ring from damage during storage, transportation and use. The superelastic alloy frame and support flex to absorb shock and when deformed rebound to their original shape.

主权项

1. A line guide assembly comprising:
a wear resistant ring having a groove defined on an outside circumference; a frame surrounding the wear resistant ring and at least partially received in said groove, said frame being part of a wireform including support and attachment portions configured to position said wear resistant ring a pre-determined distance and angular orientation relative to said attachment portion; wherein said wireform is constructed from a single, continuous length of shape memory alloy material.
