In lubricating function cavity block and vacuum function cavity block；It lubricates pump shaft and vacuum pump rotor is drivingly connected；Have on vacuum pump rotor
There is sliding groove；Sliding groove on blade and vacuum pump rotor cooperates, and blade rotates with vacuum pump rotor and can be along sliding groove straight line
Sliding；Lubricating pump shaft has hardened layer；Vacuum armature spindle has the microstructure of anti-attrition.
A kind of structure of optimization, the anti-attrition microstructure of vacuum pump rotor are the friction-reducing structures of powder metallurgy.
The structure of another kind optimization, the anti-attrition microstructure of vacuum pump rotor is nylon or phenylene sulfide structural.
The utility model with the vacuum pump rotor end face at vacuum pump cover cooperation there is ring-type to contain oil groove；Cyclic annular oil-containing
Slot oil-containing is cooling and lubricates vacuum pump.
A kind of structure lubricating function module of optimization further includes internal rotor, outer rotor；Internal rotor is matched with lubrication pump shaft interference
It closes；Outer rotor is around internal rotor eccentric rotary.
The structure lubricating function module of another kind optimization further includes rotor and slide plate；Slide plate is rotated with rotor, and along rotor
On sliding slot sliding.
The utility model has the following positive effects: vacuum pump rotor and machine oil pump shaft separate structure, powder metallurgy structure or
