A gasket (10) comprises a seal part (11) interposed between the protrusions (5, 6) of the coupling members (1, 2) while having an outside diameter smaller than the diameter of the annular recesses (3, 4), and a guide part (12) disposed on the outside of the seal part (11) while having an outside diameter being fitted in the annular recesses (3, 4). When the coupling members (1, 2) are fastened properly, the end faces thereof abut each other. An annular groove (14) is made in the outer circumference of the seal part (11) and a snap ring (13) fitted in the annular groove (14) couples the seal part (11) and the guide part (12).

摘要： Two coupling member 1, 2 are provided in respective butting end faces thereof with annular recessed portions 3, 4 surrounding respective fluid channels 1a, 2a thereof and having annular projections 5, 6 each formed in a bottom face of the recessed portion. A gasket 10 comprises a sealing portion 11 having an outside diameter smaller than the diameter of the recessed portions 3, 4 and positioned between the projections 5, 6 of the coupling members 1, 2, and a guide 12 having an outside diameter permitting the guide to be fitted into the recessed portions 3, 4 and positioned externally of the sealing portion 11. The butting end faces of the coupling members 1, 2 are movable into contact with each other when the coupling is tightened up properly. The sealing portion 11 has an annular groove 14 formed in an outer periphery thereof, and the sealing portion 11 and the guide 12 are connected together by a snap ring 13 fitted in the annular groove 14.

摘要： A coolant union includes a seal assembly (18) having a first seal member (20) and a non-rotating second seal member (22). At least one of the annular sealing surfaces (20a, 22a) presented by the rotating seal member (20) and the non-rotating seal member (22) is chamfered such that the chamfered sealing surface (22a) presents a sealing surface width less than the width of the other sealing surface. The fluid coolant union further includes a U-shaped annular secondary seal member (30) having a chamfered portion (34) structurally arranged to receive a triangular back-up ring (36) which stores sufficient relative displacement of the floating seal assembly (18) to create a separation between the first rotating seal (20) and the second non-rotating seal (22) members during the unpressurised condition.

摘要： The invention relates to a rotating method for connecting a coolant supply to a roller, in particular, on continuous casting machines. Said roller is mounted on pins in roller bearings within a bearing box and is supplied with coolant, by means of an axial drilling through the pin. A flange (2) is arranged in the roller pin, with an elastic sleeve (1) fixed in a pressure-resistant manner thereto, a sealing element (7), comprising a first sealing face, fixed to the elastic sleeve and rotating therewith, a second sealing element (8), comprising a second sealing face, which runs on the first sealing face and which is fixed to, supported by or integrated in a bearing box cover (20), with an axial drilling through the elastic sleeve and the bearing box cover for the supply of coolant to the interior of the roller. The sealing surfaces of the sealing elements are perpendicular to the axis of rotation.
