1轴瓦损伤的主要原因轴瓦的主要损伤有磨损、划痕、裂纹、剥落及腐蚀麻点等,这些损伤几乎都与润滑不良有关。造成轴瓦损伤的原因除制造上的缺陷和制造精度不高外,主要是装配、使用不当,例如:(1)润滑油中含有灰尘、铁屑或其它金属磨粒等物,将轴瓦磨损。(2)润滑系统工作不正常,机油压力过低或过高,机油供给不足或轴瓦超负荷工作造成润滑不良而磨损。(3)润滑油变质,含酸量增加,未及时更换,使轴瓦中的铅与
A main cause of bearing damage Bearing bushings are the main damage, scratches, cracks, flaking and corrosion pitting, etc., these injuries are almost all related to poor lubrication. The causes of damage to the bearing pad except for manufacturing defects and manufacturing accuracy is not high, the main assembly, improper use, such as: (1) lubricating oil contains dust, iron filings or other metal abrasive particles, the bearing wear. (2) lubrication system is not working properly, the oil pressure is too low or too high, insufficient oil supply or bearing overload caused by poor lubrication and wear. (3) deterioration of lubricants, acid content increased, not replaced in time, so that the bearing in the lead and
