A kind of water lubrication graphite sliding bearing

Technical field

The utility model relates to sliding bearing technical fields, and in particular to a kind of water lubrication graphite sliding bearing.

Background technique

The bearing that sliding bearing works under sliding friction has many advantages, such as stable working, reliable, noiseless, in liquid Under body lubricating condition, slidingsurface is separated by lubricating oil without directly contacting, and can also greatly reduce friction loss and table Surface wear, oil film also have certain vibration absorption ability, and bearing used by turbomachinery is substantially all as metal slide axis at present It holds, and by the way of oil lubrication, thus it is also larger to the demand of lubricating oil in actual use, and once lubricate Oil leakage, to will cause largely to pollute to side environment.

Existing sliding bearing, due to needing lubricating oil to be lubricated, if being applied to the driver contacted with water Tool then needs complicated seal member, enters lubricating system if any water, then easily cause bearing damage to fail, or even will appear oil Leakage Energy pollutes water environmental problems.
