RECIPROCATING MOTION SEAL COMPONENT

摘要

A reciprocating motion seal component comprises an annular elastic seal body (2). The annular elastic seal body (2) comprises at least one seal lip (3, 4), and an annular seal surface formed by the seal lip (3, 4) is provided with a concave-convex girdle (6, 7). Friction between the seal body and a shaft is reduced while ensuring that the seal body has sufficient radial seal pressure, so that motion friction of a reciprocating mechanism is reduced, and the service life of the seal body and the motion shaft are prolonged while ensuring a seal effect.
