在油润滑的设备中,加油应以油箱视镜刻度线为准。无刻度线时应符合如下规定:

1、循环润滑

正常运行时油箱油位应保持在2/3以上。

2、油环带油润滑

(1)油环内径D=25~40mm时,油位高度应浸没油环D/4。

(2)油环内径D=45-60mm时,油位高度应浸没油环D/5。

(3) 油环内径D=70~130mm时,油位高度应浸没油环D/6。

3、浸油润滑

(1)滚动轴承的浸油润滑

a.n >3000r/min时,油位在轴承最下部滚动体中心以下,但需浸没滚动体下缘。

b.n=1500-3000r/min时,油位在轴承最下部滚动体中心以下,但不得浸没滚动体下缘。

c.n <1500r/min时,油位在轴承最下部滚动体的上缘或浸没滚动体。

(2)变速机的浸油润滑

a.圆柱齿轮变速机油面应浸没高齿轮副低速齿轮齿高的2~3倍。

b.圆锥齿轮变速机油面应浸没其中一个齿轮的全齿宽。

c.蜗轮蜗杆减速机油面应浸没螺轮齿高的2~3倍,或蜗杆的一个齿高。

4、强制润滑

应按有关技术要求或实际标准确定。

5、脂润滑

(1)n >3000r/min时,加脂量为轴承箱容积的1/3。

(2)n <3000r/min时,加脂量为轴承箱容积的1/2。
