And can do when numerically-controlled precise equipment works and steadily accurately move, effectively promote the working efficiency and as received basis of numerically-controlled machine tool
Amount.
2, pass through the nozzle opening of setting, spray bar and shoe cream room, the lead screw generally usual inside when carrying out rotation work
Lead screw, which will produce serious friction, can influence the working efficiency of lead screw, it usually needs be lubricated drop to lead screw every one end time
The pressure loss of low friction, traditional lead screw transmission mechanism oil inlet and oil return is larger, can be with by using spray bar and nozzle opening
The uniform oil spout in lead screw surface of case nut interior, conducive to making lubricating oil more uniformly be output on the sliding part of lead screw, from
And the greasy property of its transmission mechanism is improved, unnecessary frictional resistance is reduced, transmission efficiency is improved.
3, by the oil-recovery tank of setting and oil return pipe, extra oil can be entered back by the through-hole of oil return rooved face
Inside oil groove, recycles oil pump and oil return pipe to convey again into inside shoe cream room, can effectively save the resource of lubricating oil, simultaneously
The pressure loss of lead screw transmission mechanism oil inlet and oil return can also be reduced.
