供X62W铣床集中润滑的润滑柱塞泵磨损严重,修复难度大,外购困难。经验算,改用 CB—B 4齿轮泵,其流量(4l/min)略大于柱塞泵。其具体改装结构如附图所示、齿轮泵 11由凸肩定位,通过 4个M 6螺栓9、弹簧垫圈10安装在盖板6上。更换轴承2的外支承套5,用4个M8的螺钉7,将套5同盖板6一起 Lubrication for X62W milling machine lubricated piston pump serious wear and tear, repair difficult, outsourcing difficulties. Experience, switch to CB-B 4 gear pump, the flow rate (4l / min) slightly larger than the piston pump. The specific modification structure shown in the drawings, the gear pump 11 is positioned by the shoulder, through the four M6 bolts 9, spring washer 10 is mounted on the cover 6. Replace the bearing 2 outer bearing sleeve 5, with four M8 screws 7, the sleeve 5 together with the cover 6
