Abstract
A seal assembly for a shaft comprising a stuffing box having an inner circular cylindrical wall surface for attachment on or in a wall having an opening for passage of a shaft therethrough. Said seal assembly having at least one first annular sealing lip of elastic material, e.g., rubber or similar material, secured at each end section of the stuffing box and which encloses and bears resiliently against the shaft, forming acute angles therewith, said first lips defining between them an annular chamber in the stuffing box for at least one annular elastic sealing member disposed between the shaft and the inner circular cylindrical wall surface of the stuffing box. Said sealing member is composed of a second annular sealing lip of elastic material cor-responding to the material in the said first sealing lips, which second sealing lip is releasably and resiliently retained on the shaft for rotation therewith and extends obliquely outward toward the inner wall surface of the stuffing box, forming an acute angle with the shaft, the vertex of said acute angle is turned toward the shaft passage opening in the wall which bounds on a room having a dust- or particle-filled atmosphere and/or a moisture or fluid-filled room.
