摘要： The mechanical seal for a rotating, axially movable shaft is esp. for heavy duty shafts subjected to thermally-induced longitudinal expansion e.g. alternating current generating machines. One sealing element (3) is mounted on the shaft and rotates with it. A threaded nut (5) on the shaft presses the seal against a shoulder (6) on the shaft. A sealing ring (8) of a stationary sealing element (7) is pressed against the rotating sealing element (3) by a spring (9). The fixed seal is held by a support ring (12) which is movable axially with the shaft. The support ring is prevented from rotating by several holder pins (24) between the housing (1) and ring.

摘要： PROBLEM TO BE SOLVED: To provide a processing method capable of improving accuracy in the eccentric direction of eccentric parts in a shaft having a plurality of eccentric parts. SOLUTION: This processing method of the shaft having the plurality of eccentric parts for forming the eccentric parts, by cutting and grinding the plurality of eccentric parts 7 and 13a of a workpiece 1, by forming concentric shafts 9a, 9b and 9c, by cutting and grinding a part except for the plurality of eccentric parts 7 and 13a of the workpiece 1 becoming the shaft having the plurality of eccentric parts; is characterized in that a workpiece side positioning line is arranged on a concentric shaft 9a with the pre-molded referential eccentric part 7 as a reference, by using an eccentric tool 23 provided with two tool side positioning lines orthogonal to an end surface; the eccentric tool 23 is fixed to the workpiece 1 by positioning the tool side positioning line passing through the center of a hole of the eccentric tool 23 and a workpiece side positioning line of the workpiece 1; and the other eccentric part 13a is fabricated, by installing the workpiece 1 on a lathe, by chucking the eccentric tool 23 by a four-claw chuck 11, by positioning a claw 11a and the tool side positioning line passing through the center of the end surface of the eccentric tool 23.
