Latest Patents

Two of Robert W. Postma's latest patents showcase his ingenuity and commitment to solving complex engineering challenges.

The first is the **Corrugated Slider Washer Bearing**, designed for a bolted interface assembly. This innovative bearing allows relative differential thermal expansion and contraction between a component plate and a base plate without generating excessive strains or stresses. This slider washer operates as a thin spacer that aids in achieving high preload tightening while facilitating unidirectional alternating motion between the plates. The inclusion of at least one mating groove arranged horizontally enhances the performance by guiding the relative motion while minimizing friction shear forces.

The second patent is the **Clip Flexure Slider Washer Bearing**, which also addresses thermal expansion issues in bolted interfaces. This bearing acts as a lubricated thin spacer, thereby enabling high preload tightening while facilitating relative sliding motion. The design integrates slider washer portions between two parallel metal clip flexures, constraining motion to unidirectional translation and effectively managing stresses during thermal cycles.
