Specific implementation mode
Further the utility model is illustrated below in conjunction with attached drawing.
As shown in Figure 2, Figure 3 and Figure 4, embodiments herein provides a kind of gasket assembly, is installed on rotor 1, rotor 1
One end is stretched into the bearing 2 being fixed on equipment shell, which includes：
Gasket seat 3, fixing sleeve is set on rotor 1, can be rotated synchronously with rotor 1 when rotor 1 rotates, gasket seat
A circle groove is formed on 3；
Ball 4 is multiple, and rotatable in groove；And
Flat shim 5 is placed on outside rotor 1, and with the port detachable connection of bearing 2, it is, flat shim 5 can
Fixed one end for sticking on bearing 2, when rotor 1 rotates, flat shim 5 does not rotate together with rotor 1, but relative rotor 1
Static；The limit of ball 4 is in flat shim 5 and 3 enclosed space of gasket seat.
Axial force is will produce when rotor 1 rotates, which can drive rotor 1 to move axially, that is, rotor 1 can revolve
It is moved axially while turning.Gasket seat 3 can be driven to 5 direction pushing tow ball 4 of flat shim when rotor 1 moves axially, while band
Dynamic ball 4 rolls on flat shim 5.It is, gasket assembly is integrally supported with 2 phase of bearing, to apply resistance to rotor 1, support
Disappear its axial driving force, forces 1 axial position of rotor to be fixed, rotor 1 is avoided to generate larger axial displacement.
Further, in the embodiment of the present application by fixing flat shim 5 and the port of bearing 2, prevent flat shim 5 with turning
Son 1 rotates together, effectively to avoid flat shim 5 from generating larger friction with the port of bearing 2 due to being rotated with rotor 1, thus contracts
The service life of short flat shim 5.In addition, since rotor 1 is high-speed rotating, it is desirable to offset its axial force, the generation of friction is
Inevitably, but in the embodiment of the present application gasket seat 3 and flat shim 5 are substituted by the rolling friction between ball 4 and flat shim 5
Between be in direct contact the friction of generation, reduce when rotor 1 rotates gasket assembly to greatest extent to prevent rotor 1 from moving axially
When and the frictional force that must generate, that is, by the minimum friction forces, therefore significantly extend gasket assembly and rotor 1
Service life.
