ROTARY JOINT FOR SEGMENT OF STEEL MANUFACTURING FACILITY

摘要

The present invention relates to a rotary joint for a segment of a steel manufacturing facility and, more specifically, to a rotary joint for a segment of a steel manufacturing facility which prevents wear by installing a bush which is an oilless bearing on both ends of a rotor even when pushing or pulling a mono-elbow if a length of a flexible hose is short or long, and prevents abnormal wear on a portion where the rotor and a thrust bush are tightly attached to each other and a portion where a snap ring and the thrust bush are tightly attached to each other. The rotary joint (1000) for a segment of a steel manufacturing facility includes a sealing means. The sealing means (1100) includes: a casing (1110) inserted into an end of a roller (130) to be fixed; a cover (1120) which is inserted into a center of the casing on a side where a mono-elbow (180) is present to be assembled, and has a dust seal (1121) on an inner circumference of the cover; a rotor (1130) inserted in an axial direction of the casing and the cover on an opposite side where the cover is inserted; a thrust bush (1150) installed on a position tightly attached to the end of the casing inserted into the roller and a position tightly attached to the side into which the cover is inserted on an outer circumference of the rotor via a snap ring (1140); dynamic packing (1160) and a second chamber (1180) installed on an inner circumferential surface of the casing from an inner position to an outer position of the roller; and an oilless bearing (1190) installed in a prescribed diameter and width between the second chamber and the cover. Also, an oilless bearing (1190) is further installed between the dynamic packing and the thrust bush (1150) inserted into a head (1131) of the rotor (1130).;COPYRIGHT KIPO 2018
