Abstract

The present invention addresses the problem of eliminating the influence of the tolerance of the receiving end or the inserted end and facilitating the connecting of a pipe joint using a lock ring. In this pipe joint structure, a lock ring groove (12) is formed in the inner surface of a receiving end (2), a lock ring (10) is housed within that lock ring groove (12), and a retaining protrusion (11) that protrudes toward the outer-diameter side is provided at the tip of the inserted end (1). When an attempt is made to pull the inserted end (1) out from the receiving end (2) after the inserted end (1) has been inserted into the receiving end (2), the retaining protrusion (11) makes contact with the lock ring (10) and is retained. In addition, the configuration is such that the lock ring (10) is equipped with a single-split ring part (10a) that opens at one location in the circumferential direction, and with protrusions (10b) that rise in the outer-diameter direction from the ring part (10a), and the receiving end (2) and the ring part (10a) are centered when the protrusions (10b) directly contact the bottom face of the lock ring groove (12). The lock ring groove (12) is equipped with a tapered inner surface part (12e), the diameter of which increases gradually from the opening in the pipe axial direction of the receiving end (2) to the interior in the pipe axial direction, and the protrusions (10b) are housed opposing that tapered inner surface part (12e).

Abstract

Disclosed is a rotation braking device for a rotor, comprising: a rotor which rotates axially relative to a housing; a magnetic disk conjoined with the rotor; and an electromagnet disposed so as to sandwich the disk and provide gaps therearound, which when power is supplied provides a magnetic circuit in the direction in which the disk is sandwiched. The disk of the rotation braking device for a rotor holds fluid with magnetic viscosity in the gaps between the rotor and the like and the housing and the like. The end parts of the gaps positioned outside of the turning radius of the rotor are physically sealed, and the end parts on the opposite side are sealed by the provision of a permanent magnet which provides magnetic force to fluid with magnetic viscosity held in the vicinity.
