机床上用的各种润滑泵,一般不需要专门的电机带动,只接在机床的某一传动链上,带动润滑泵排油。在机床的变速箱中,由于主轴要求经常正反转运转,因此要求润滑泵在主轴反转时,不改变进出油口而继续排油以保证润滑。有一些机床,如钻床Z525等由于润滑泵在主轴反转时不能排油造成润滑不良,损坏机件。一般机床上能在主轴正反转时正常排油的是柱塞泵。这里介绍一种不需改变进出油口,正反转都能排油的齿轮润滑泵,它比柱塞泵结构简单紧凑;体积小,便于在机床变速箱中放置;工作可靠。
A variety of lubrication pumps used on machine tools, generally do not need special motor driven, only in a transmission chain of the machine, driven lubrication pump oil discharge. In the gearbox of the machine tool, because the main shaft requires frequent positive and negative rotation, it is required that the lubricating pump continue to discharge oil without changing the inlet and outlet ports to ensure lubrication when the main shaft is reversed. Some machines, such as drilling Z525, etc. due to the lubrication of the pump shaft can not be inverted oil caused by poor lubrication, damage to the parts. In general, when the spindle can rotate normally and reversely, it is the plunger pump. Here to introduce a without changing the inlet and outlet, positive and negative can be discharged oil lubrication gear pump, piston pump than the structure is simple and compact; small size, easy to place in the machine gearbox; Reliable work.
