箱体类部件如搅拌器、减速器、变速器、液力耦合器和泥浆泵的泵送部分等,工作时承受较大的扭矩和转速。此类部件常见故障有输入轴窜动、输出轴断裂、输出轴滚键、齿轮损坏、轴端漏油、箱体开裂和轴承损坏等。1.漏油箱体类部件漏油一般是输入及输出轴密封处漏油,尤其是输入轴密封处漏油最为常见。链条传动的箱体,链条越长,漏油越严重;一些配用内胀式 Box-type components such as agitators, decelerators, transmissions, fluid couplings and mud pump pumping parts, etc., work under greater torque and speed. Common failures of such components have input shaft movement, the output shaft fracture, the output shaft rolling keys, gear damage, oil leakage at the shaft end, box cracking and bearing damage. 1. Leakage oil tank parts leakage is generally input and output shaft seal at the oil leakage, especially the input shaft seal at the most common oil leakage. Chain drive box, the longer the chain, the more serious oil spills; some with inflation
