Description
Technical field
The invention belongs to Component of Hydraulic Turbines technical field, more particularly, to a kind of water pilot bearing.
Background technology
Water guide shoe can bear the radial load of hydraulic turbine main shaft, be the bearing that main shaft can be made to keep center.Extensively
Applied to fields such as turbine-generator units, large pump, cement grinding mill, ball grinder bush, ship machineries.And water guide shoe is when mounted
It needs to be determined that the center of hydraulic turbine main shaft and generator amature, then press the gap of the physical location adjustment bearing of axle.And
Do not have a kind of gap width that when mounted can be directly between auxiliary adjustment bearing shell and axle in the prior art most preferably to set to reach
The device of evaluation, in addition, needing to remove bearing after bearing wear, the gap width between bearing shell and axle is adjusted again, it has not been convenient to
Maintenance in the future；Water guide shoe bearing oil blocking barrel of the prior art can stop fluctuation when the fry dried food ingredients in oil groove gives birth to fluctuation
Oil, do not allow oil to cross oil blocking barrel and spill, but the oily effect of gear is not good enough, oil is still easily spilt, in addition, lubricating oil is in bearing
Surface distributed is not uniform enough, is unfavorable for lubricating.
In order to be improved to prior art, people have carried out long-term exploration, it is proposed that various solutions.
For example, Chinese patent literature discloses a kind of combination bearing gap adjusting structure [application number：CN201120168857.6], by axle
