Title: Innovations of David B Sugden in Rock Boring Technology
Introduction
David B Sugden, an accomplished inventor based in Tasmania, Australia, has significantly contributed to the field of rock boring technology with a remarkable portfolio of 17 patents. His innovative designs showcase a deep understanding of mechanics and engineering, driving advancements in rock cutting tools and devices.
Latest Patents
Among Sugden's latest inventions are two notable patents: his rock boring device and an oscillating disc cutter with speed-controlling bearings. The rock boring device features a rotary disc cutter that operates in an oscillating manner, allowing for enhanced precision in rock excavation. This device includes a mounting section that can be angularly offset from the driven section, enabling the cutter to oscillate and nutate effectively.
The oscillating disc cutter employs a complex drive mechanism, which facilitates eccentric oscillation of the cutting disc. Its sophisticated design includes a radial bearing that allows relative rotation between the drive shaft and the cutting disc, along with a hydrostatic axial bearing that reactively handles axial forces while managing induced rotation. The innovative use of a water-pressurized fluid bearing ensures predictable performance by maintaining a predetermined maximum running clearance in the hydrostatic bearing.
