Abstract

1,052,735. Shaft seals. KOPPERS CO. Inc. June 18, 1965, No. 25992/65. Heading F2B. A seal 10 for a rotary shaft 16 comprises a sealing ring 58 located in an annular recess 40 in a housing 28 and having at one end an axially extending lip portion 62 with a conical external surface 63, a radial flange 66 at the other end and a cylindrical external surface 72 between the lip portion 62 and the flange 66, a wedge ring 78 which surrounds the lip portion 62 and urges it into sealing contact with the shaft, and a support ring 74 that overlies the surface 72 and is urged axially by a corrugated spring washer 86 between it and the wedge ring 78 to thereby press the flange 66 into sealing engagement with a wall 42 of recess 40. The ring 78 is urged against the lip portion 62 by a garter spring 82 and the washer 86 presses the ring 82 against a back-up plate 84. A pin projecting inwardly from the housing 42 engages an axial slot in the ring 74 to prevent rotation of the latter. The sealing ring 58 and the wedge ring 78 may be of glass-filled " Teflon " (Registered Trade Mark) and the support ring 74 may be of metal. In a modification, Fig. 4 (not shown), the seal is retained in the housing 112 by a pair of split rings 118 and the radial flange 146 of the sealing ring 134 is inclined. In a further modification. Fig. 6 (not shown), two seals 110 are arranged backto-back separated by a spacer 174 vented to atmosphere.
