Abstract
A disk mountable on a rotating support has one side at least partially covered with an elastomer loaded with magnetic particles to form an encoder while the other side of said disk axially limits an annular chamber. A sealing structure attached to the disk and contained within the plane of a lateral side of a support capable of supporting a non-rotating component of the seal with incorporated encoder is mountable within an annular cavity which is axially limited by the plane.
Claims12
A seal with incorporated encoder comprising:
- a disk, mountable on a rotating support, the disk having a first surface and a second surface offset axially outwardly of the first surface, the first surface being on a first side of the disk;
- an elastomer loaded with magnetic particles covering at least a portion of the first surface of the disk while the second side of said disk axially limits an annular chamber, the elastomer with magnetic particles comprising an encoder;
- and
- sealing means in contact with the second surface of the disk;
- the disk, encoder and first sealing means all being contained within the plane of a lateral side of a support capable of supporting a non-rotating element of the seal.
