ANTIFRICTION BEARING Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: antifriction bearing is designed to work on solid lubricant. Antifriction bearing includes outer and inner races provided with chutes with rolling solids of revolution mounted between them and located in cage. Cage consists of two ring-shaped members. Cage is connected with scrapers located in spaced relation in chute of ring by means of connecting member-concentrator. Scrapers are used for motion of powder of solid lubricant. Each connecting member-concentrator is mounted in scraper and in cage for mutual axial displacement. Both ring-shaped members of cage may be mounted forming rolling solids of revolution between them and connected by means of connecting members-concentrators of chutes, thus enhancing circulation of solid lubricant powder in seats of cage. EFFECT: improved circulation of solid lubricant in seats of cage. 2 cl, 3 dwg
