Y310滚齿机液压润滑系统的原理如附图所示。经多年使用,存在如下二个问题: 1.叶片泵输出压力油(系统压力为10～13kgf/cm~2)的一部分经单向阀4去润滑工作台的圆平面和变速箱。压力油润滑工作台圆平面后,将从圆平面的间隙溢出,流到冷却油池中去,使润滑油池的油位降低到叶片泵的吸油口以下,工作中需补充油液。为了节约油液,通常是将冷却油池中的油再抽回到润滑油池中去,造成润滑油严重污染。含有杂质(主要是金
Y310 hobbing machine hydraulic lubrication system as shown in the figure. After years of use, the following two problems exist: 1. Vane pump output pressure oil (system pressure of 10 ~ 13kgf / cm ~ 2) part of the check valve 4 to lubricate the worktable round surface and gearbox. After the pressure oil lubricates the workbench round plane, it will overflow from the clearance of the circle plane and flow into the cooling oil pool to lower the oil level of the lubricating oil tank below the oil suction port of the vane pump, and the oil needs to be replenished during the work. In order to save oil, the oil in the cooling sump is usually pumped back into the sump to cause serious pollution of the lubricating oil. Contains impurities (mainly gold
