为使C 620-i车床床头箱达到较好的润滑效果,采用两种润滑方法:摩擦离合器和主轴前轴承用强制方法润滑,采用往复式油泵供油;箱内其它机构用飞溅法润滑。有些油被齿轮溅到床头箱上盖四周弧形的内壁上,由于弧口朝下,使溅在上面的油很快流到床头箱壁上端的贮油槽中,经毛线导油再去润滑其它机件。做好润滑工作是降低设备故障率的重要手段之一。C 620-1车床床头箱润滑系统常见的故障是油泵供油量不足。从油窗观察,油是往下滴油
In order to achieve a better lubricating effect on the C 620-i lathe headstock, two lubrication methods are adopted: the friction clutch and the front spindle bearing are lubricated by a forced method and the reciprocating oil pump is used for oil supply; other mechanisms in the box are lubricated by a splash method. Some oil is splashed on the headboard cover around the arcuate inner wall, due to the arc mouth down, so that the oil spilled on the top of the bed quickly flow to the top of the sump, the oil guide go go Lubricate other parts. Lubrication work is to reduce equipment failure rate of one of the important means. C 620-1 lathe headstock lubrication system common fault is insufficient fuel pump. Observed from the window, the oil is dripping down
