Abstract:The paper reports an energy conserved hydrodynamic journal bearing registered in a patent,
which was realized by the boundary slippage technology. This kind of bearing possesses an obviously
better operation in the carried load and the friction coefficient than a conventional type of bearing for
the same operating condition especially when the eccentricity ratio of the bearing is no more than
0.28. The increase of the load-carrying capacity of this bearing can reach 100%, while at the same
time the reduction of the friction coefficient of this bearing can be 60%, compared to a conventional
bearing in the same operating condition. The energy conservation and load improvement effects of this bearing is very
significant.
