The outer tegillum of tegillum, inner bearing in bearing, inner bearing, supporting plate, tegillum, casing composition in inner bearing；End cap endoporus is provided with outer
Bearing, end cap two sides seam one side connection host housing, another side connection casing, tegillum and outer tegillum pass through bolt in outer bearing
It is pressed on end cap, there is supporting plate in casing, supporting plate is used to fix inner bearing, and supporting plate endoporus is provided with inner bearing, interior axle
Tegillum is held in outer tegillum and inner bearing by bolt presses on the supporting plate, it is small outside outer tegillum and inner bearing to have covered oil filler point,
It is small in tegillum and inner bearing in outer bearing to have covered outage；Main shaft is housed on outer bearing and inner bearing.
Compared with prior art, the beneficial effects of the invention are as follows：After coal quo of local Fan for Mine increase transmission case, it lubricates
Performance significantly improves, and when increased shaft coupling eliminates impeller rotation, axial force, radial load and out-of-balance force, avoids bearing from burning
Phenomena such as bad, retainer dissipates happens occasionally；Its service life extends one times compared with common direct-connection type blower fan, effectively protects
The demand of underground constant ventilation is demonstrate,proved.
