Abstract
910,191. Stuffing-box substitutes. KUNEL, H. March 4, 1959 [March 5, 1958; Nov. 29, 1958], No. 7580/59. Class 122 (5). An elastic sealing bush 2 for a movable shaft 6 has closed internal circumferential lubricant grooves 4 inclined to its axis and a sealing lip 12a, 13 at each end of its bore. The grooves overlap in the axial direction and are preferably parallel to each other and may be planor or, as shown in Fig. 3, undulating. The bush has a locating flange 1 which, in the assembled position shown in Fig. 4, is clamped between the stuffing-box wall 7 and the gland 8. The bore of the bush is less than the shaft diameter and may be barrel-shaped or progressively decrease toward the lip 13. The walls of the grooves are preferably inclined to the butyl axis in the direction of the pressure to be sealed. The bush may be of polyurethane, neoprene, or " Perbunan " (Registered Trade Mark). To facilitate assembly the grooves are filled with lubricant and the bush is expanded by a cone 102, Fig. 5, entered with its small end 105 adjacent the flanged end of the bush and then pushed therethrough by a tubular tool 100 having a tapered end 101 to engage a notch 104 in a rubber seal 103 on the cone. To insert the seal, the tool 100 with the seal mounted thereon is pushed on the shaft and the tool then removed by pulling on extracting means 109, the seal being left in position on the shaft.
