The first back-up ring be used for limiting rotary body and the second bearing group inner ring relative to play, the first described oil sealing
Being arranged in housing, described flange screw the second bearing group outer ring is also fixed on by the first screw group
On housing, installing the first O between flange and housing, the first O is in seal casinghousing
Hydraulic oil, the second described oil sealing is arranged in flange, and the first oil sealing and the second oil sealing rotate against
Body rotates and hydraulic oil in seal casinghousing；Also include: ventilating joint；Described ventilating joint includes:
Fittings body, the 3rd bearing group, the second back-up ring, third gear circle, sealing member, the second O, compensation
Groups of springs；Described fittings body is supported on housing by the 3rd bearing group, and the second described back-up ring is used
In restriction the 3rd bearing group and the relative play of housing, described third gear circle is for limiting the 3rd bearing
Group and the relative play of fittings body, in described sealing member is arranged on housing and can axially move by relative housing
Dynamic, sealing member is adjacent to fittings body end face in counterbalance spring group effect lower surface form flat seal face,
For sealing joint body compressed air, the second O is installed between sealing member and rotary body,
For sealing gas circuit compressed air.
Compared with prior art, the beneficial effects of the utility model are: owing to being channel structure, its
Middle first passage conveying compressed air, second channel delivery hydraulic pressure oil, thus at a swivel joint list
Realize conveying compressed air and hydraulic oil in unit simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
