SEALING MODULE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; seals of pairs of rotary and reciprocating motion. SUBSTANCE: sealing module includes reinforced elastomer collar 1 having sharp sealing edge adjoining supporting member and spring 6. Edge of collar is made in form of two sharp sealing edges forming circular chamber; bearing member on which collar 1 is mounted is made in form of bush with bead and flange. Contact surfaces of bearing member, edges of collar and cavities between two edges are provided with solid lubricant coats forming antifriction film at friction. Solid lubricant coat, for example SURM-T provides for low friction coefficient. EFFECT: reduced coefficient of friction; improved operating conditions. 1 dwg
