Description
Technical field
The present invention relates to rotary joint technical field more particularly to a kind of shock reducing type rotary joint structures.
Background technique
Rotary joint is a kind of connecting component, is used to for medium being transmitted in rotating pipe from static pipeline, especially exist
The industrial applications such as metallurgy, ship lifting, chemical industry, pharmacy are very extensive, in the rigid conduit of trandfer fluid, the two of relative rotation
It needs that rotary joint is installed between a pipeline, to realize the rotation connection of pipeline.Since the shell of rotary joint is usually all
In static, and rotary part is connect with outside rotating pipe, and when exterior line high speed rotation will necessarily generate vibration, thus
So that rotary part in rotary joint and bounce radially, axially occurs between the shell of rotary joint, usual rotary joint
Sealing ring is all set between interior rotary part and shell, sealing ring can be applicable in small circular runout, however rotary part with
It is tight fit between the axial direction of shell, relative displacement can not be generated, therefore axial runout can not be overcome, when rotary part rotates
To a biggish axial vibration power is generated between shell, which can generate a frequent impact force to shell, in turn
The whole service life of rotary joint can be reduced.
