从理论上分析了内圈与轴过盈量对轴承径向游隙的影响，并在内圈与轴不同过盈量情况下对 QJS207轴承进行了断油性能试验。结果表明：当轴承内圈与轴过盈量为0．014～0．015 mm 时，轴承可断油运转17～19 s；当内圈与轴过盈量为0．005～0．006 mm 时，轴承可断油运转30 s。
從理論上分析瞭內圈與軸過盈量對軸承徑嚮遊隙的影響，併在內圈與軸不同過盈量情況下對 QJS207軸承進行瞭斷油性能試驗。結果錶明：噹軸承內圈與軸過盈量為0．014～0．015 mm 時，軸承可斷油運轉17～19 s；噹內圈與軸過盈量為0．005～0．006 mm 時，軸承可斷油運轉30 s。
종이론상분석료내권여축과영량대축승경향유극적영향，병재내권여축불동과영량정황하대 QJS207축승진행료단유성능시험。결과표명：당축승내권여축과영량위0．014～0．015 mm 시，축승가단유운전17～19 s；당내권여축과영량위0．005～0．006 mm 시，축승가단유운전30 s。
The effects of magnitude of interference between inner ring and shaft on radial clearance of bearings is theo-retically analyzed,and the oil -interruption performance test for bearings QJS207 is carried out under different magni-tude of interference between inner ring and shaft.The results show that the bearings operate 1 7 ~1 9 s after oil -inter-ruption when magnitude of interference is 0.01 4 ~0.01 5 mm,30 s for 0.005 ~0.006 mm.
