Abstract
The utility model relates to a high-speed rotary joint, which comprises a rotary body and a shell assembly connected with the rotary body. The rotary body comprises a joint body, a bearing and a dynamic sealing element; the bearing is arranged on the outer wall of the joint body, and axial drifting of the bearing is controlled through a shaft by using a retainer ring; the dynamic sealing element is fixedly connected to one end of the joint body; the shell assembly comprises a shell, a thrust ring, a static sealing element and a compression spring; the thrust ring is arranged in an inner pipe of the shell, and the thrust ring can move axially relative to the shell; a limiting pin is arranged on the shell and used for limiting the thrust ring to rotate relative to the shell; one end of the static sealing element is fixedly connected to one side of the thrust ring, and the end face of the other end of the static sealing element is attached to the end face of the dynamic sealing element to form a tight sealing face; the compression spring is arranged in the inner pipe of the shell; a spacing ring and an O-shaped ring are arranged between the compression spring and the other side of the thrust ring; the rotary body is arranged in the shell, and axial drifting of the rotary body is controlled through a hole by using a retainer ring; and an oil cup for adding lubricating oil to the bearing is also arranged on the shell.
Description
Technical field
The utility model relates to a kind of revolving joint that is widely used in high-speed rotating machine, in order to realize the transmission of static pipeline to the rotating equipment flowing medium, relates in particular to the structure of this revolving joint.
Background technique
The swivel joint of existing technology adopts O type rubber seal or other rubber seal to seal at the static and dynamic sealing place; This type seal form is that seal ring is installed in the circular trough, realizes sealing through the certain decrement of rubber, when Sealing and another part are done when relatively rotating; Because rubber produces big resistance to rotation surface; Sealing part just can be generated heat, and when under fast state, turning round constantly, temperature can raise rapidly; Seal ring damages rapidly under high-temperature, and build-up of pressure descends, dielectric leakage.
The model utility content
The utility model technical issues that need to address have provided a kind of high-speed joint, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme:
The utility model comprises: solid of rotation and the frame set that joins with solid of rotation; Described solid of rotation comprises: fittings body, bearing and dynamic seal; Described Bearing Installation is on the fittings body outer wall, through shaft block ring control axial float; Described dynamic seal is fixed on the end of fittings body; Described frame set comprises: housing, Thrust ring, static seal, pressure spring; During described Thrust ring was installed on and manages in the housing, Thrust ring housing relatively moved axially; On described housing, position limit pin is installed, is used for the limit thrust ring and rotates relative to housing; One end of described static seal is fixed on Thrust ring one side, and the other end end face and said dynamic seal end face are fitted and formed the tight seal face; During described pressure spring is installed on and manages in the housing; Spacer ring and O type circle are installed between the opposite side of described pressure spring and Thrust ring; Described solid of rotation is installed in the housing, controls axial float through the hole with back-up ring; The lubricating cup that is used for adding lubricant oil to bearing also is installed on said housing.
Compared with prior art; The beneficial effect of the utility model is: adopt high abrasion carbonization silicon materials to be applied on the swivel joint as Sealing; It is overheated to realize that swivel joint rotates under fast state; Dynamic and static Sealing not only has good sealing property and wear automatic-compensation characteristic, also has very long working life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Visible by Fig. 1, the utility model comprises: solid of rotation and the frame set that joins with solid of rotation; Described solid of rotation comprises: fittings body 2, bearing 3 and dynamic seal 7; Described bearing 3 is installed on fittings body 2 outer walls, through shaft block ring 11 control axial floats; Described dynamic seal 7 is fixed on the end of fittings body 2; Described frame set comprises: housing 1, Thrust ring 5, static seal 6, pressure spring 4; During described Thrust ring 5 was installed on and manages in the housing 1, Thrust ring 5 housing 1 relatively moved axially; Position limit pin 10 is installed on described housing 1, is used for the limit thrust ring and rotates relative to housing 1; One end of described static seal 6 is fixed on Thrust ring 5 one sides, and the other end end face and said dynamic seal 7 end faces are fitted and formed the tight seal face; During described pressure spring 4 is installed on and manages in the housing 1; Spacer ring 8 and O type circle 9 are installed between the opposite side of described pressure spring 4 and Thrust ring 5; Described solid of rotation is installed in the housing 1, controls axial floats through the hole with back-up ring 12; The lubricating cup 13 that is used for adding lubricant oil to bearing 3 also is installed on said housing 1.
The material of said dynamic seal 7 and static seal 6 adopts high abrasion carbonization silicon to process.
