There is gland to fix outside seal ring, pollute for preventing the pollutant of outside from entering oil sump through the gap location between enclosing cover and reciprocal axle
Lubricating oil.
Described in the utility model toward multiplexing suspension servo sealer, described front T-shaped set external diameter overlaps external diameter phase with rear T-shaped
Deng, and it is more than the external diameter of seal and rotary packing ring；Such setting can make seal and rotary packing ring be completely in T-shaped set
Parcel under, be beneficial to promote rotary packing ring motion on the premise of, there is better seal.
Described in the utility model toward multiplexing suspension servo sealer, described enclosing cover and inner cap are fixing even by screw
Connect.
Described in the utility model toward multiplexing suspension servo sealer, by the knot of the seal box black box interior with it
Close, utilize seal, spring, T-shaped set and seal ring set to be connected on reciprocal axle realize effectively sealing, inner seal diameter face with reciprocal
Axle is fitted, and outer diameter face is wrapped under T-shaped set and is in a kind of suspended state, constantly with axle back and forth run, axle remain highly with
Heart position, it is to avoid because off-centring causes leakage of oil to occur, and it during use, is not necessarily to manual adjustment, complete Automatic adjusument,
And this practical described sealing device uses simple, Renewal process is simple, is suitable to popularization and application.
