一、改造原因 2×φ1130×1150双转子锤式破碎机传动主轴是两根细长三支点平行轴,分别支持在三个用油环润滑的滑动轴承上(图1)。该机在破碎中硬或硬质砂岩时,转子轴有较大弯曲,致使滑动轴承经常发生烧瓦事故,两平行转子轴均系三支点静不定结构,拆装检修极不方便,常因检修时间多而影响生产,利用率低。为此,我们对该机传动系统进行了技术改造。 First, the reasons for the transformation 2 × φ1130 × 1150 double rotor hammer crusher transmission spindle is two slender three-fulcrum parallel to the shaft, respectively, supported in the three oil-lubricated sliding bearings (Figure 1). The aircraft in the crushing of hard or hard sandstone, the rotor shaft has a greater curvature, resulting in frequent occurrence of sliding bearing bush accident, the two parallel rotor shaft are three branches of static structure, disassembly overhaul extremely inconvenient, often due to overhaul Time and affect production, utilization is low. To this end, we have a technical transformation of the drive system.
