Abstract

1429939 Shaft seals GEORGE ANGUS & CO Ltd 26 June 1973 [29 June 1972] 30417/72 Heading F2B In a rotary shaft seal of the type shown in Fig. 1 comprising a moulded ring 1 of elastomeric material having a sealing lip 4, 5 with a sealing edge 6 defined by a moulded face 8 on the air side of the seal, the elastomeric material has a Young's modulus between 3À5 and 8À5 MN/m.<SP>2</SP> and the face 8 is concave, Fig. 4, and a tangent thereto where it meets the edge 6 is at an agle # to the ring axis of between 50 and 80 degrees. In Fig. 4 the lip is shown before trimming on line 7a or 7b to form the trim face 7 and edge 6. Preferably, the face 8 is a ring segment of a spherical surface the radius C being between 2 mm. and 7 mm. The seal may be of nitrile or silicone rubber.
