过去YQ—100深孔钻机在我矿的使用过程中寿命是不长的。钻水平孔的使用寿命为7～14天(三班作业,下同),钻向上斜孔为3～7天,钻90°向上孔为2～3天,甚至只使用1天就损坏了。主要齿轮箱中两齿轮的齿很快就磨损得象刀口一样,甚至齿都扫平了;新的307轴承磨损得滚珠跑出或内外圈碎裂等。齿轮损坏是什么原因呢?实践证明齿轮的强度和滚珠轴承的工作能力系数是足够的。齿轮和
In the past, the YQ-100 deep-hole drilling rig was not long-lived during the use of mine. The service life of a horizontal hole drilled is 7 to 14 days (three shifts, the same below), the inclined hole for drilling is 3 to 7 days, the upward hole for 90 ° is 2 to 3 days, and even the damage for one day is damaged. The gear teeth of two gears in the main gearbox wear out very quickly, like tooth edges, and even the teeth are swept out; the new 307 bearing is worn out and the balls run out or the inner and outer rings are fragmented. What is the reason for gear damage? Practice has proved that the strength of the gear and ball bearing work capacity factor is sufficient. Gear and
