Latest Patents
One of Katagiri's latest inventions is a torque limiter. This device comprises an inner ring fitted inside an outer member, with a torque transmission member interposed between them. A predetermined torque is generated through friction between the inner ring and the torque transmission member when they rotate relatively to each other. The members are impregnated with lubricating oil to facilitate smooth sliding. The lubricating oil consists of synthetic saturated hydrocarbon oil with a kinematic viscosity of 500 to 1200 mm/s at 40°C, along with an emulsifier.
Another significant patent is the electroconductive grease-filled bearing. This rolling bearing features an inner race and an outer race, with steel balls retained between their track surfaces. It is designed to support the edge of a heating roll in an electrostatic transfer copying machine. The electroconductive grease used in this bearing comprises fluorocarbon oil as a base and graphite or polytetrafluoroethylene as a thickening agent. This grease effectively discharges static electricity and maintains heat-resistant durability, ensuring optimal performance in high-temperature environments.
