Abstract
An improved seal arrangement for a drive mechanism of the type having a rotating member and a radially spaced stationary member with a bearing mounting the rotating member on the stationary member, as in a clutch assembly for an air conditioning compressor, is disclosed. The seal arrangement includes a first seal support member carried by the rotating member on one side of the bearing, a second seal support member carried by the stationary member on the other side of the bearing, and an annular fluoroplastic-coated felt seal member. The first and second seal support members are located and dimensioned to overlap each other to provide an annular volume therebetween and the annular felt seal member is dimensioned and located to fill at least a portion of such annular volume, one side of the felt seal member being secured to one of the support members and the other side of the felt seal member being in rotary sealing engagement with the other seal support member. An embodiment of the invention in which the annular volume extends radially outwardly of the felt seal member to provide a slinging action to further prevent material detrimental to the bearing from entering through the seal is described.
