摘要:为满足矿用宽体车负荷大、整车振动大、使用工况差、曲轴后端跳动大的需求,设计开发轴向密封结构油封;开展油封抗偏心跳动能力试验、油封泵吸能力试验、摩擦转矩试验等零部件功能试验,结合整机耐久试验,对比轴向和径向密封结构油封的抗偏心跳动能力、泵吸能力、摩擦转矩、摩擦功损耗、可靠性和使用寿命。结果表明:相对传统径向密封结构油封,轴向密封结构油封的抗偏心跳动能力更优,泵吸能力更强,摩擦转矩和摩擦功损耗更低,可靠性更高,使用寿命更长。使用轴向密封结构油封可以解决矿用宽体车油封漏油问题,降低市场故障率。

Abstract:To meet the needs of the mining wide body vehicles with heavy load, high vibration, poor working condition and large jump at the back end of crankshaft, the oil seal of axial seal structure has been developed. The oil seal eccentric run-out resistance test, pump suction capacity test, friction torque test, parts durability test and whole machine durability test are carried out. The results showed that the axial seal structure has better eccentric run-out resistance, lower friction torque and friction work loss, higher reliability and longer service life than the traditional radial seal structure. The oil seal of axial seal structure can solve the oil seal leakage problem of mining vehicle, and reduce the failure rate of the market.

Keywords:oil seal; axial seal; radial seal; eccentricity run-out; pump suction; friction torque
