Crankshaft 40 is supportted, so as to 1 service ability of compressor and operational reliability, and passes through setting negative pressure component 60 and the channel that oils
410, negative pressure component 60 can form negative pressure in center oilhole 400 by oiling channel 410, by the lubricating oil in oil sump 11
It sucks in center oilhole 400, during lubricating oil flow, lubricating oil can flow through motor bearings 50, rotor 310 and compression group
Part 20, so as to form lubricating action between motor bearings 50, rotor 310, compression assembly 20 and crankshaft 40, so as to
The abrasion of motor bearings 50, rotor 310, compression assembly 20 and crankshaft 40 is reduced, the rotational efficienty and reliability of crankshaft 40 are improved,
And then the service performance of compressor 1 can be improved.
