Abstract

The utility model discloses a transition shaft type rotating joint. The transition shaft type rotating joint comprises a shaft (1) and is characterized in that a spring (12) is located on step end faces at two ends in a shell (2), the other end of the spring (12) is arranged to be in contact with a sealing ring with embedded graphite (3), and an auxiliary sealing ring (14) is installed in a groove for the sealing ring with the embedded graphite (3). An end face of a moving ring (4) is sealed with the graphite of the sealing ring with the embedded graphite (3) in a frictional mode, a bearing (11) is arranged between the inner wall of the shell (2) and the external diameter of the sealing ring with the embedded graphite (3), and a flange pressing the bearing (6) is fixed on the shaft (1) through a screw. A locking screw (17) is screwed into a screw hole of the flange pressing the bearing (6) and is embedded in a locking groove of the moving ring (4), and a flange (18) is fixed on the shaft (1) through a screw. The transition shaft type rotating joint has the advantages of being large in compensation amount, long in service life, good in sealing, high in rotating speed and convenient to change and maintain.

Description

Transition shaft type swivel joint
Technical field
The utility model relates to a kind of swivel joint, particularly a kind of transition shaft type swivel joint.
Background technique
In the rotary reaction batch can of milk recycling of packaging industry, swivel joint is not the outermost end that is installed in the rotation gudgeon of equipment, and is mounted in the neutral position of revolution motor and retort.On the coupling shaft in the middle of this just need to be enclosed within swivel joint, volume virtually just strengthened the volume of swivel joint, caused difficulty is installed, owing to can't adopt the Mechanical Sealed Type structure greatly, cause compensation rate too small, low, easy leakage of life-span, low, the replacing maintenance inconvenience of rotating speed.
Summary of the invention
The utility model provides a kind of compensation rate larger for above-mentioned the deficiencies in the prior art, life-span length, good seal, rotating speed height, replacing swivel joint easy to maintenance.
The technical solution of the utility model is: transition shaft type swivel joint, comprise: axle 1, shell 2, edge graphite-seal ring 3, rotating ring 4, transparent cover 5, last item holds flange 6, rotation stopping screw 8, bearing 11, spring 12, seal ring 13, auxiliary seal ring 14, auxiliary seal ring 15, outside framework oil seal 16, rotation stopping screw 17, flange 18, it is characterized in that: an end of described spring 12 is positioned at the ladder end, two ends, inside of shell 2, the other end of spring 12 contacts setting with edge graphite-seal ring 3, edge graphite-seal ring 3 is installed in the inner radius of housing 2, locate spline with screw, auxiliary seal ring 14 is installed in the groove of edge graphite-seal ring 3, rotating ring 4 end faces are friction sealed with edge graphite-seal ring 3, bearing 11 is arranged between shell 2 inwalls and edge graphite-seal ring 3 external diameters, transparent cover 5 cooperates by screw with bearing 11 shell 2 is linked into an integrated entity, outside framework oil seal 16 transparent cover 5 internal diameters of packing into, seal ring 13 is contained in shell 2 internal diameter grooves, rotation stopping screw 8 is installed on the external diameter of axle 1, in the shell 2 parts endoporus that axle 1 inserts after assembling, last item holds flange 6 and is screwed on axle 1, rotation stopping screw 17 is screwed into last item and holds in flange 6 screws and be embedded in the spline groove of rotating ring 4, and flange 18 is screwed on axle 1.
The utility model advantageous effect: compensation rate is large, the life-span is long, good seal, rotating speed high, it is easy to maintenance to change.50 rev/mins of the utility model maximum speeds, maximum pressure is 1.0MPa, is applicable to cooling water, the media such as air.
