Abstract: Seal leakage in medicinal high-speed grinder is one of the problems probe and research by equipment designer and user. In this paper, a new structure of seal is designed with a combination of micro-nano magnetic fluid seal and mechanical lubricating ring. Sealing structure has been optimized through tests on the reliability. Experimental results show that the method can better solve the seal leakage in Medicinal high-speed grinder.

Abstract: The oil seal of the high-speed non-woven loom needle spindle is a difficult problem, which has always been probed among the product manufacturer and the users. A new structure, the micro-nanon magnetic fluid seal plus the packing seal, is designed in this paper. It is suitable for the high-speed linear reciprocating spindle. The new structure is applied to the practical production. Through the productive experiments, the reliability of the structure is further optimized. So the reliability problem of the needle spindle oil seal is well solved.
