1.故障现象我处2005年购置了6台2000型油井压裂车,经长期使用后,部分压裂车的艾里逊CL-T9880型变速器输出轴出现漏油故障。更换输出轴油封后使用不久又发生漏油,反复更换输出轴油封,始终不能彻底解决输出轴漏油问题。2.原因分析变速器输出轴油封部位结构如附图所示。分析认为,该型变速器输出轴漏油原因有以下5方面:一是油封质量有问题;二是输出法兰盘轴颈油封密封部位磨出环形槽;三是变速器输出轴径向跳动或轴向窜动异常;四是输出法兰盘锁紧螺母松动;五是变速器油面超过油面线。
1. Symptom I purchased six 2000-type oil well fracturing trucks in 2005. After long-term use, oil leakage faults occurred on the output shaft of Allison CL-T9880 transmission of some fracturing vehicles. Replace the output shaft seal soon after the oil leakage occurred, repeated replacement of the output shaft seal, the oil can not be completely solved the problem of oil leakage. 2. Analysis of the reason Transmission output shaft seal structure shown in the figure. Analysis, the type of transmission output shaft leakage causes of the following five aspects: First, the quality of the oil seal problems; Second, flange flange seal oil seal ring out of the annular groove; Third, the transmission output shaft radial runout or axial Abnormal movement; Fourth, the output flange nut lock loose; Fifth, the transmission oil surface exceeds the oil line.
