DECANTER CENTRIFUGE PROVIDED WITH CONTINUOUS GREASING DEVICE

摘要

Provided is a decanter centrifuge provided with a continuous greasing device capable of suitably preventing leakage of lubricating oil along the supply pathways and of stably supplying and discharging lubricating oil. The centrifuge is provided with a continuous greasing device having a lubricating oil supply channel (17) formed inside a bowl hub (6), an annular introduction channel (25) that introduces the lubricating oil into the lubricating oil supply channel (17), a lubricating oil infusion channel (30) formed inside a holder (14), and an oil collector (34) installed on the outer surface (13a) of an outer shaft (13). The annular introduction channel (25) is configured of a first annular groove (15) formed inside the holder (14) and the outer surface (13a) of the outer shaft (13), which occludes the groove from the inside. The oil collector (34) is configured to revolve in a prescribed direction on an orbit inside the annular introduction channel (25) and when so doing, to move lubricating oil in the annular introduction channel (25) inward in the radial direction so as to flow into the lubricating oil supply channel (17).
