C620-1车床床头箱里装有30号机油,润滑情况由油窗观察。其油面应达到油平面指示处,油面过低会导致润滑不良,油面过高时,由于齿轮高速旋转的摩擦也会引起发热,并增加了功率的损失。主轴前轴承由往复式油泵供油,经多片式滤油器滤净,经油管至前轴承。其工作是否正常,可由油窗观 C620-1 lathe bed box with 30 oil, lubrication observed by the oil window. The oil level should reach the oil level indication, the oil level is too low will lead to poor lubrication, oil level is too high, due to high-speed gear rotation friction will cause fever, and increased power loss. Spindle bearings by the reciprocating oil pump, filtered by the multi-chip filter, the tubing to the front bearing. Whether its work is normal, can be viewed from the window
