Title: Jeffrey Arnold LeBlanc: Innovator in Fluid Dynamics
Introduction
Jeffrey Arnold LeBlanc is a notable inventor based in Aptos, CA (US). He has made significant contributions to the field of fluid dynamics, particularly in the design of bearings and seals for motor systems. With a total of 2 patents, his work has advanced the reliability and efficiency of various mechanical systems.
Latest Patents
LeBlanc's latest patents include innovations such as the Fluid Dynamic Bearing and Pumping Seal. This invention provides a fluid dynamic bearing motor that features relatively rotatable facing surfaces that are effectively lubricated. A radial gap is defined between these surfaces, with a larger gap at one axial end compared to the central region. This design establishes a fluid recirculation passageway, enhancing the robustness of the motor and reducing sensitivity to external loads or mechanical shocks. Additionally, it minimizes the risk of dry contact between bearing surfaces, which can lead to performance issues or failures.
Another significant patent is the Hub and Spindle Assembly, which incorporates first and second fluid dynamic journal bearings and thrust bearings for a disc drive memory system. This assembly includes a pump seal and a radial ring seal for lubricant containment, along with a capillary seal and a labyrinth seal for additional storage. The design minimizes lubricant fluid pressure differences, thereby reducing fluid loss and purging air bubbles through circulation channels.
