Development of Rubber Dust Seal with Metal Insert for Gear Shaft of EMU
Through the optimization design of rubber formula and vulcanization mold,adhesive se-lection and performance verification test,a inserted rubber dust seal with high and low temperature re-sistance and wear resistance for gear drive shaft was developed.Through the combination of different brands FKM and the reasonable selection of vulcanization system,the low temperature resistance of the rubber material was enhanced.Through the synergy of metal insert phosphating treatment and ad-hesive,the bonding strength of FKM/metal insert was improved.By cleverly designing vulcanization molds and ejection tooling,the molding and demolding efficiency of products was improved.The test results of the bench test showed that this type of rubber dust seal had excellent wear resistance and met the performance requirements of the EMU during high-speed operation.
