为保持油封对轴具有稳定的径向压力,以实现油封的可靠密封,在油封刃口处,需设置自紧螺旋弹簧,随时予以补偿自紧。因此可以说,油封的密封性,在很大程度上取决于自紧螺旋弹簧的设计制造质量。随着机械工业的发展,对油封质量的要求越来越高,已经把油封看成是相当于一个精密轴承的总成。所以,橡胶油封专业生产厂家,加强对影响油封密封性能极大的自紧螺旋弹簧设计制造质量的研究,是非常有必要的。
In order to maintain the oil seal on the shaft with a steady radial pressure, in order to achieve a reliable sealing of the oil seal, the oil seal edge, the need to set self-tightening coil spring, to be self-tightening at any time. Therefore, it can be said that the seal of the oil seal depends largely on the design and manufacturing quality of the self-energizing coil spring. With the development of the machinery industry, the quality of the oil seal is getting higher and higher, and the oil seal has been regarded as the equivalent of a precision bearing assembly. Therefore, the professional manufacturer of rubber seals, to strengthen the seal on the seal performance of self-tight coil spring design and manufacturing quality of research is very necessary.
