In prior art, tilting bush sliding bearing comprises bearing body and is connected to the multiple tilting pads on bearing body between bearing body and rotating shaft, the two ends of tilting pad are disposed with oil suction chamber and oil back chamber by the sense of rotation of rotating shaft, position corresponding with oil suction chamber and oil back chamber on bearing body is respectively arranged with oil inlet hole and spill port, in use, lubricant oil is added to oil suction chamber by oil inlet hole, at this moment the temperature of lubricant oil is generally 45 DEG C, afterwards, lubricant oil enters oil back chamber in rotating shaft, and the lubricating oil temperature at this moment after over-rotation engagement generally can reach more than 100 DEG C, due to the oil suction chamber of two adjacent tilting pads and the spacing of oil back chamber very near, oil-feed and fuel-displaced very easy mixing under the drive of rotating shaft, cause the inlet oil temperature of one of them tilting pad very high, and then the temperature of whole bearing is all raised, affect the normal work of bearing.
Therefore, how to provide a kind of tilting bush sliding bearing, oil-feed and fuel-displaced mixing can be avoided, reduce the inlet oil temperature of tilting pad 3, thus reduce the temperature of whole bearing, ensure the normal work of bearing, become the important technological problems that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
In view of this, the invention provides a kind of tilting bush sliding bearing, oil-feed and fuel-displaced mixing can be avoided to reach, reduce the inlet oil temperature of tilting pad, thus reduce the temperature of whole bearing, ensure the object of the normal work of bearing.
For achieving the above object, the invention provides following technological scheme:
A kind of tilting bush sliding bearing, comprise bearing body and be connected to the multiple tilting pads on described bearing body between described bearing body and rotating shaft, the two ends of described tilting pad are disposed with oil suction chamber and oil back chamber by the sense of rotation of described rotating shaft, position corresponding with described oil suction chamber and described oil back chamber on described bearing body is respectively arranged with oil inlet hole and spill port, multiple described tilting pad is provided with oil separating plate along the radial direction of described bearing body between any two, and described oil separating plate is removably connected on described bearing body.
Preferably, described bearing body and described tilting pad removably connect.
Preferably, described tilting pad is connected by the first bolt with described bearing body.
Preferably, described oil separating plate is connected by the second bolt with described bearing body.
As can be seen from technique scheme, tilting bush sliding bearing provided by the invention, between any two the radial direction of bearing body is provided with oil separating plate at multiple tilting pad, oil separating plate is removably connected on bearing body, by arranging oil separating plate, multiple tilting pad is isolated, oil-feed on each tilting pad and oil return are not interfere with each other, the oil-feed between two adjacent tilting pads and oil return mixing can be avoided, reduce the inlet oil temperature of tilting pad, and then reduce the temperature of whole bearing, ensure that the normal work of bearing.
