The utility model provides a support arrangement for between finishing mill shaft coupling and axle bush, belongs to lubricated technical field, and the purpose prevents that the shaft coupling from refueling the in -process rotor and to axle bush direction drunkenness, its technical scheme being, including screw rod and two supporting shoes during the device constitutes, the both ends of screw rod are equipped with soon to opposite external screw thread, and the middle part of two supporting shoes all is equipped with the screw hole, internal thread in the screw hole of the two respectively with the external screw thread phase -match at screw rod both ends. The utility model discloses the supporting role who utilizes screw rod both ends supporting shoe stops the rotor to axle bush orientation drunkenness, makes maintain the safety distance between shaft coupling and the axle bush, not only can make lubricating oil reach backlash smoothly, guarantees the lubricated effect of shaft coupling, can effectively avoid axle bush burn accident in addition, reduces the economic loss of enterprise. The screw rod is used for adjustable support means's length, makes strutting arrangement's dismantlement very convenient.
