我厂现有两台DQ3025型斗轮堆取料机。于1975年投产后成为原料场取料、堆料、中和混匀的关键设备。由于设备运转已达十年之久,回转机构经常出现故障。其主要原因是大型推力交叉滚柱轴承的滚道磨损严重,个别滚柱损坏。但是回转轴承一直没有进行过检修。若动用大量人力、物力拆吊回转部份检修轴承,其工作量等于大修,势必影响生产。但经过分析,知道此种轴承属可拆卸式轴承。图1为回转轴承的结构示意图。其回转轴承圈分为上、下两部份,由4个M24的螺钉
I plant the existing two DQ3025 bucket wheel stacker reclaimer. After being put into operation in 1975, it becomes the key equipment for raw material field to take materials, stack material, neutralize and mix well. Rotary bodies often fail because the equipment has been running for decades. The main reason is the large thrust crossed roller bearing raceway wear serious individual roller damage. However, slewing bearings have not been overhauled. If you use a lot of manpower, material removal demolition rotary part of the overhaul bearings, the workload is equal to overhaul, it is bound to affect the production. But after analysis, know that this bearing is a removable bearing. Figure 1 shows the structure of the slewing bearing. The rotary bearing ring is divided into upper and lower two parts, by the four M24 screws
