车床溜板箱内光杠上,原装的06084齿轮上的两套轴承—06049是非标准滚针轴承,由机床厂生产。因此轴承坏了,无配件,维修困难,造成停机。为解决此问题,我们改用“国标”4084110 滚针轴承,其余有关零件也作了相应改变(见附图)。如先将06084齿轮与4084110 滚针轴承相配处磨成槽,再进 On the light bar in the slide box of the lathe, two sets of bearings on the original 06084 gear are the non-standard needle roller bearings manufactured by the machine tool factory. Therefore, the bearing is broken, no parts, maintenance difficulties, resulting in downtime. To solve this problem, we use the “GB” 4084110 needle roller bearings, the remaining parts have also been made corresponding changes (see photo). If the 06084 gear and 4084110 needle bearing match at first grinding into the groove, and then into
