Sealing arrangement for a rotatable member

Claim 1

A sealing arrangement for sealing a stationary member to a rotatable member, said arrangement comprising a stationary member and a rotatable member, a pair of rubbing seals mounted on one of said rotatable and said stationary members in rubbing engagement with a cylindrical surface of the other of said members, said rubbing seals being relatively closely spaced to form a sealant space therebetween extending radially from said rotatable member to said stationary member and circumferentially and continuously about said rotatable member, said stationary member having a sealant passage extending therethrough in communication with said sealant space, means for injecting fluid sealant through said passage and into said sealant space so that said sealant space is completely filled with said sealant to form a continuous sealing band of said sealant extending circumferentially about said rotatable member, and said sealant space including opposed and laterally extending channel means communicating therewith and extending behind opposed rubbing lips of said rubbing seals respectively to increase the flexibility thereof and to positively engage said lips with said other member and wherein said rubbing seals are symmetrically opposed with respect to one another; and including said rotatable member configured as a roll neck and wearing ring mounted thereon, and further including, said stationary member configured as a bearing chock for said roll neck.
