Keywords: crankshaft seals, resistance, reduced frictional resistance


The article discusses the cooperation of the elastomeric sealing ring with the shaft in terms of wear and losses to overcome friction forces, the construction of a classic seal and a seal with reduced resistance to movement. Because the lip-shaft system is a specific friction pair, the focus has been on local micro contact conditions as a parameter that determines global motion resistances on a macro scale. Since the occurrence of premature sealing failure in spite of small costs of the element itself generates serious costs of repair and downtime of the transport fleet, the problem of durability and reliability of the described type of seals remains valid.
