Title: Innovations of Ritchie J Lee
Introduction
Ritchie J Lee is an accomplished inventor based in Harrisburg, NC (US). He has made significant contributions to the field of engineering, particularly in the development of advanced drive rollers for tape cartridges. With a total of 3 patents to his name, Lee's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Lee's latest patents include a "Molded roller for tape cartridge" and a "Method of molding unitary roller of homogeneous material for tape." Both patents describe a drive roller for a belt-driven tape cartridge that is molded from composite polymeric material in a single step. The design features an outer segment and an inner segment that are integrally formed together with a radial web segment. This configuration provides highly concentric operating surfaces on both segments. The inclusion of carbon powder in the composite material ensures electrical conductivity throughout the molded drive roller. Additionally, selective shrinkage during cooling creates desirable bearing surfaces within the inner bore. The thrust bearing surfaces at the ends of the inner segment engage with mating surfaces that include lubricant traps, which help to inhibit the migration of lubricant away from the bearing surfaces. The stepped inner bore and axially spaced corresponding stepped axle diameters promote lower frictional drag, provide a reservoir for lubricant, and facilitate the removal of the molded component from its cavity.
