滚柱定向离合器使用多年后出现打滑失效,拆检时发现滚柱被磨成棱柱状,而星体平面仅有极轻微压痕,用油石轻轻打磨即能修平,更换新滚柱后仍能正常工作,然而,短期又重复出现上述现象。我们对被磨损的滚柱逐个检查,其淬火硬度完全符合技术要求,而星体平面上基本未见压溃情况,经分析,该离合器不属于一般正常失效现象。如图所示,当星体按矢向转动,滚柱在缝楔中受 Roller-oriented clutch slippery after years of failure, dismantling found that the roller was ground into a prism, and the astral plane only a very slight indentation, polished with whetstone that can be smooth, after the replacement of the new roller can still be normal However, the above phenomenon has been repeated in the short run. We have to check the worn roller one by one, the hardness of its quenching fully meet the technical requirements, and the basic plane of the plane was not crushed basically, after analysis, the clutch does not belong to the normal normal failure phenomenon. As shown in the figure, when the star rotates in the sagittal direction, the roller is affected by the wedge
