Further, annular groove inside and outside staggering of position of opening.Have the annular groove that staggers at supporting outer ring and supporting inner ring respectively, each interlocking has a seal ring with the supporting inner ring to make supporting outer ring, makes its structure more reasonable, helps improving the sealing effect of seal ring.
Further, seal ring is a rubber seal ring.Seal ring adopts the structure of rubber seal ring can let seal ring and bearing ring surface closely cooperate, and improves sealing effect.
Further, described seal ring comprises Steel Skeleton and covers the kiss-coating on the Steel Skeleton.Adopt the mode that covers kiss-coating on the Steel Skeleton can not only improve the sealing effect of seal ring, and can improve the tough and tensile degree of seal ring, prolong the life-span of seal ring.
Further and have a boss that a projection is arranged on the relative opposite side bearing ring of the bearing ring of annular groove.This boss ability and seal ring are worked in coordination, and seal ring can more closely be attached in the supporting, further improve the water proof and dust proof effect of pivoting support.
Further, described kiss-coating comprises sealing outer lip and sealing epipharynx, sealing outer lip and inside and outside bearing ring, the plane be connected, seal the surface that epipharynx is close to bearing ring.The sealing outer lip can form one and have the excellent sealing effect seal ring between supporting inner ring and supporting outer ring; Can prevent effectively that extraneous steam from entering into the inside of supporting; The sealing epipharynx also has and prevents that inner grease from leaking and the function of oxidation except having the effect that improves sealing effect.
Further described sealing epipharynx closely contacts with boss.Sealing epipharynx and the tight of boss contact, and can let the sealing configuration of the seal ring formation second layer, have improved the sealing of seal ring greatly.
The beneficial effect of the utility model is: the sealing configuration of a kind of pivoting support of the utility model; Mode through interlocking seal ring in bearing ring; Can on pivoting support, form a seal protection circle; Make pivoting support form the structure of an inner sealing, improve the water proof and dust proof effect of pivoting support.The utility model is simple in structure, cost economy, effect are fine, adopts this structure can improve the barrier propterty of pivoting support, plays the effect that prolongs its life-span, reduces maintenance cost.
