我厂摸索出一种新的减速机轴头密封——螺旋密封法,初步解决了减速机的漏油问题。在减速机初轴、末轴的通盖部位,紧靠轴承的内圈的外侧,各装一个轴套(螺旋密封套),此轴套以静配合方式紧固在轴上,随轴转动。在轴套的外圈处加工与各轴的旋转方向相反的双头锯齿形螺纹,螺旋套螺纹外径与轴套内径不同心度不大于0.02毫米,并使螺纹锯齿形(双头)推力面向内。在通盖的内径处加工一个横向突出的圆台,使通盖内径处的宽度与轴 I plant to find out a new reducer shaft seal - screw seal method, the initial solution to the reducer oil spill problem. In the reducer shaft, the end of the shaft cover parts, close to the outer bearing inner ring, each fitted with a sleeve (spiral seal sleeve), the sleeve with a static fit fastened to the shaft, with the shaft rotation. The outer ring of the sleeve is machined with a double-serrated thread opposite to the rotating direction of each shaft. The outer diameter of the thread of the spiral sleeve does not concentric with the inner diameter of the sleeve more than 0.02mm, and the thread serrated (double-headed) thrust faces Inside. In the cover of the inner diameter of the processing of a transversely protruding conical table, so that the inner diameter of the cover width and shaft
