In technique scheme, described moving assembly comprises rotating ring, rotating ring O type circle, rotating seat; Described rotating seat is connected with described rotating ring by described rotating ring O type circle; Wherein, described spring seat and described rotating seat are respectively arranged with the claw of a plurality of projectioies, described spring seat and described rotating seat are by the clamping mutually of described claw, and described rotating ring outer ring also is provided with a plurality of transmission ears, and described transmission ear is connected between the claw of described rotating seat.
In technique scheme, described quiet assembly comprises stationary seat, stationary seat O type circle, stationary ring O type circle, stationary ring, one end of described stationary ring contacts with described rotating ring, the other end of described stationary ring and described stationary seat are tightly connected by described stationary ring O type circle, and described stationary seat is connected by pad with described positioning ring; Described stationary seat O type circle is connected in the end of described stationary seat near described positioning ring.
In technique scheme, described positioning ring is provided with a plurality of screws, and described axle sleeve correspondence is provided with a plurality of through holes, and described positioning ring is fixedlyed connected by described screw, through hole with described axle sleeve.
In technique scheme, described spring seat and described rotating seat are respectively arranged with the claw of three uniform projectioies, and described rotating ring outer ring also is provided with three transmission ears.
In technique scheme, described pad is a Tetrafluoro spacer.
Compared with prior art, the utlity model has following beneficial effect: owing to adopted stainless steel integrated integrated mechanical sealing, make that assembling and replacing are very convenient, improved sealability, prolonged the working life of product, simultaneously, integral seal is not subject to the influence of processing dimension and axle play yet
