Abstract
A high-pressure high-speed rotary connector comprises a shell body, a rotary outer pipe and bearings, wherein the left end of the rotary outer pipe is installed in the upper end of the shell body, and the bearings are arranged at the left side and the right side respectively and are respectively installed at the left end of the rotary outer pipe with a through cavity in the shell body as the central line. The high-pressure high-speed rotary connector further comprises sealing rings, wherein the sealing rings are installed on the rotary outer pipe at the inner sides of the bearings, a bearing check ring is designed at the outer side of each bearing, a bearing cover is designed outside each bearing check ring, each bearing cover is fixed to the shell body through a bolt, every two sealing rings form a set, the sealing rings form two sets with the through cavity in the shell body as the central line and are respectively installed on the rotary outer pie, a bearing outer sealing ring is further designed on the rotary outer pipe, and the bearing outer sealing ring is installed at the outer side of the bearing at the right side. The high-pressure high-speed rotary connector has the advantages of being used on sheet winding equipment, adopting a balance sealing principle, using the precise high-speed bearings for supporting in the middle, reducing eccentric wear of the sealing rings, and pronging the service life.
Description
Technical field
The utility model relates to a kind of high pressure seal, relates in particular to a kind of high pressure high speed rotating joint.
Background technique
Swivel joint is a kind of connection seal arrangement of dynamic rotary system that flowing medium is input to from static system, existing swivel joint by steel ball as support, machined steel ball receway on housing and rotation outer tube, if surface treatment is improper, easily cause alley hardness inadequate, component distortion, in use easily mill is inclined to one side for seal ring, owing to not being balanced type sealing means, housing is relative with rotation outer tube is in use subject to larger power for joint, can cause steel ball rolling channel rapid wear, affect working life.
