Title: Damon T. Landrum: Innovator in PDM Transmission Technology

Introduction

Damon T. Landrum is a notable inventor based in Spring, Texas, who has made significant contributions to the field of transmission technology. With a total of three patents to his name, Landrum has focused on innovations that enhance the functionality and efficiency of Positive Displacement Motors (PDM).

Latest Patents

Landrum's latest patents include groundbreaking designs for PDM transmissions. The first patent describes a PDM transmission with articulated torque transfer. This invention features a ball-CV style transmission that utilizes a shaft with wings received into housing receptacles. A Unitary Torque Transfer Element (UTTE) is interposed between each shaft wing and housing, allowing for effective torque transfer during articulated rotation. The UTTEs are designed to float within their corresponding housing receptacles, ensuring consistent torque transfer contact.

The second patent focuses on a PDM transmission with sliding contact between convex shaft pins and concave bearing surfaces. This design incorporates unlaminated bearings, or Torque Transfer Elements (TTEs), which slide and displace within pockets in the housing. As the shaft tilts during misaligned rotation, the convex curved bearing surfaces on the shaft pins rotate against the concave curved bearing surfaces on the TTEs, facilitating smooth operation.
