ABSTRACT:
The invention relates to a stuffing box for the sealed passage of a shaft with undesirable deflection through connecting branch, provided with a casing, a stuffing box sland containing packing rings, as well as with a tubular spring compensator, one end of which is rigidly and releasably engaged with the connecting branch, the other end with the casing of the stuffing box. At least one guide bush (10) is arranged in the casing (8) centering the stuffing box (7) to the shaft (2). This guide bush can be arranged between the packing rings (9, 9a) and over (11) of the casing, and it is made of material, suitably of bearing material with low friction coefficient. Flanges (20, 21) are arranged on each end of the compensator (4), and one flange (20) is rigidly and releasably coupled with the connecting branch (1), the other flange (21) with the stuffing box (7) suitably by screw joints (14,15), and the two flanges (20,21) are interconnected by means of screws passing through the holes of the flanges, allowing slight flexible radial and axial displacement. The flexible coupling takes up the radial deflection and the slight axial displacement of the shaft.
