Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of novel high speed train wheel hub bearing seal device, including skeleton 1, metal outside metal
Inner sleeve 2 and rubber dicheilia 3, the inner metal sleeve 2 are located at outer 1 inside of skeleton of metal, and rubber dicheilia 3 is located at metal 1 He of outer skeleton
Between inner metal sleeve 2, the outer skeleton 1 of metal is by vulcanization and 3 tight bond of rubber dicheilia, the rubber dicheilia 3 and metal
Inner sleeve 2 is coordinated using contactless transition, and is filled with lubricating grease between the two；The rubber dicheilia 3 includes the oily bead of gear
4, two lips 6, main lip 8, one of lip 9 and rain cover 10, the oily bead 4 of gear are located at the lower section of rubber dicheilia 3, two lips 6
Positioned at the side of rubber dicheilia 3, the lip 9 with together with of main lip 8 is located at the top of rubber dicheilia 3, and rain cover 10 is located at inner metal sleeve 2
Outside, be equipped with reflow bump 5 between the gear 4 and two lip 6 of oily bead, maze trough be equipped between two lips 6 and main lip 8
