摘　　要：探讨SL系列胶辊轴承径向游隙对使用寿命和纱线质量的影响。分析了胶管结构变化对轴承径向游隙的影响;通过跟踪试验对比了不同径向游隙对胶辊回转状态、使用周期和成纱指标的影响,指出套铝衬辊后实际径向游隙应控制在0.005mm^0.007mm。在铝衬胶辊套制时,要充分清洗并处理新轴承,严格控制外壳直径公差,使铝衬辊内孔与轴承外壳形成合理的过盈配合;定期检查套辊机;认真对待润滑脂的选择和加注量。认为:胶辊轴承径向游隙的合理选择可延长胶辊的使用寿命,成纱质量可进一步提高。The influences of radial clearance for SL series top roller covered roller bearing on working life and yarn quality were discussed. The effect of rubber tube structure changes on bearing radial clearance was analyzed. By tracking experiments,the influences of different radial internal clearances on rotation condition, usage period and yarn indexes when using different rubber-covered roller were compared. It was pointed out that the practical radial clearance of aluminium-inserted rubber tube should be controlled within 0. 005 mm - 0. 007 ram. When making aluminium-inserted rubber tube, new bearing needs to be fully cleaned and treated. The tolerance of sheave diameter should be strictly controlled so that reasonable match could be formed between inner hole of aluminium- inserted rubber tube and bearing sheave. The roller covering machine need to be checked regularly. The selection and adding amount of lubricating grease should be carefully considered. It is considered that rubber-covered roller working life can be prolonged and yarn quality can be improved furtherly by reasonably selecting radial clearance of top roller bearing.
