Description
Technical field
The present invention relates to fan bearing water-cooling structure field, flows CO soon in particular to a kind of axle2Laser blower fan it is straight
The cold bearing arrangement of water receiving.
Background technology
Axle flows CO soon2Laser is a kind of gas laser, and the laser that it sends is by exciting CO2Gas molecule to height
Again to caused by low energy order transition after energy level, except CO in working gas2, typically also have He, N2Deng auxiliary gas.CO2
The electrical efficiency of laser typically up to 20~25%, i.e. the electrical power of input service gas there are about 20~25% can be converted into it is sharp
Light output, and remaining 75~80% are mainly discharged in the form of heat energy, its direct result is exactly working gas temperature
Rapid rise, and the rise of working gas temperature can weaken condition caused by laser --- population inversion, make power output
Reduce, until not having power output completely, to reduce working gas temperature, axle flows CO soon2Laser manufacturer can all use
Roots vaccum pump or roots blower produce high velocity air and carry out cooling to working gas by heat exchanger.
During actual use, (sub- vacuum chamber is as described above, interior in a sub- vacuum chamber for the rotary shaft of blower fan or turbine
Contain a small amount of CO in portion2, He and N2), this sub- vacuum chamber connects with vavuum pump, by the swabbing action of vavuum pump, keeps sub- true
The high-speed mobile of empty intracavity gas, specific structure are：Bearing inner race is fixed in one side end of fan rotation shaft, and bearing is fixed
Bearing spider is formed on bear box, rotary shaft opposite side is sub- vacuum chamber.Prior art is typically in bearing backwards to rotary shaft
Side vavuum pump is set, bearing and leave pumping gap, the connection of pumping gap vavuum pump and sub- vacuum chamber, vacuum between rotating
Pump aspirates the gas in sub- vacuum chamber by the gap.In addition, in order to ensure the fluency of rotary shaft and bearing operation, rotary shaft
With needed on bearing add lubricant grease lubrication.
The direction of this Vacuuming structure gas flowing is, sub- vacuum chamber --- rotary shaft --- bearing --- vavuum pump,
Such flow direction can make lubricant grease directly flow to bearing from rotary shaft, and cartridge housing end, bearing operation are flowed to from bearing
Time it is longer, the lubricant grease on bearing and rotary shaft is fewer.Because bearing is in airtight chamber, the addition of lubricant grease
Highly difficult, long time running easily causes rotary shaft and bearing damage.In addition, the gap of pumping connects with sub- vacuum chamber, bearing
In operation process, lubricant grease can be entered in sub- vacuum chamber by the oil gas of thermal evaporation, pollute the gas composition in sub- vacuum chamber,
Influence the operation of laser.
The content of the invention
Present invention aim to the bearing arrangement for the prior art for solving to mention in above-mentioned background technology to have lubrication
