High-pressure high-speed dual-path rotating joint

Abstract

The invention discloses a high-pressure high-speed dual-path rotating joint, which comprises a flange rotating shaft, a circlip for hole, a combined retainer ring support sleeve for hole, a combined retainer ring snap ring for hole, a thrust ball bearing, a sleeve gasket, a nozzle, a deep groove ball bearing, a snap ring for shaft, an elastic retainer ring for shaft, a first combined seal ring, a second threaded passageway, a second combined seal ring, a shell, a fourth threaded passageway, a rotary retaining threaded hole, a third threaded passageway and a first threaded passageway. The high-pressure high-speed dual-path rotating joint is characterized in that the circlip for hole, the combined retainer ring support sleeve for hole and the combined retainer ring snap ring for hole are sequentially arranged in the shell; an outer ring of the thrust ball bearing is fixedly arranged in the shell; an inner ring of the thrust ball bearing is fixedly inlayed on the flange rotating shaft; and the sleeve gasket is arranged between the inner ring of the thrust ball bearing and an inner ring of the deep groove ball bearing. The rotating joint is simple in structure, good in sealing performance, and applicable to high-pressure high-speed rotation, and meets the requirement of two-path medium transfer.

Description

technical field [0001] The invention belongs to a rotary joint, in particular to a high-pressure, high-speed rotary dual-path rotary joint. Background technique [0002] In the prior art, in pneumatic and hydraulic equipment and speed control machining centers, there is often a need to transport two-way media to high-pressure and high-speed rotating equipment. The use of ordinary rotary joints has a short service life, frequent replacement, and waste of material and financial resources. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a high-pressure, high-speed, dual-path rotary joint with simple structure, good sealing performance, suitable for high-pressure high-speed rotation and dual-path medium transmission. [0004] The technical scheme of the present invention is: a high-pressure high-speed dual-path rotary joint, including a flange rotating shaft 1, a circlip 2 for a hole, a support slee...
