Abstract
The present disclosure provides for the description of rotary unions. The described rotary unions are provided with a non-rotating union part and a rotating union part affixable to a rotating device. An exemplary rotary union can be positioned relative to a bearing supporting the rotating device and the rotating device or can be incorporated into a bearing supporting the rotating device.
Claims20
A rotary union comprising:
- a rotating union part rotatable about an axis and matingly engageable with a rotating device, said rotating device being rotatable about said axis and having a fluid channel disposed therein, said rotating device being disposed about, and supported by, a shaft wherein said shaft is supported by a support bearing;
- a non-rotating union part disposed coaxially about said rotating union part;
- and,
- a fluid passage disposed within said rotary union, said fluid passage comprising:
- a fluid material inlet disposed upon a surface of said non-rotating union part;
- a first portion in fluid communication with said fluid material inlet disposed within said non-rotating union part;
- and,
- a second portion disposed within said rotating union part and having a fluid material outlet disposed upon a surface of said rotating union part in fluid communication therewith;
- wherein said surface of said rotating union part is matingly engageable with said rotating device to provide fluid communication of a fluid from said fluid passage to said fluid channel;
- wherein said fluid is communicatable through said fluid passage from said fluid material inlet, through said first portion, into said second portion, to said fluid material outlet, and to said at least one fluid channel;
- and,
- wherein said rotary union is disposed between said rotating device and said support bearing.

A rotary union comprising:
- a rotating union part rotatable about an axis and matingly engageable with a rotating device, said rotating device being rotatable about said axis and having a fluid channel disposed therein;
- a non-rotating union part disposed coaxially about said rotating union part and coupled to a support structure, said non-rotating union part comprising a support bearing, said support bearing being disposed between said non-rotating union part and said rotating union part, said support bearing supporting said rotating device;
- and,
- a fluid passage disposed within said rotary union, said fluid passage comprising:
- a fluid material inlet disposed upon a surface of said non-rotating union part;
- a first portion in fluid communication with said fluid material inlet disposed within said non-rotating union part;
- and,
- a second portion disposed within said rotating union part and having a fluid material outlet disposed upon a surface of said rotating union part;
- wherein said surface of said rotating union part is matingly engageable with said rotating device to provide fluid communication of a fluid from said fluid passage to said fluid channel;
- and,
- wherein said fluid is communicatable through said fluid passage from said fluid material inlet, through said first portion, into said second portion, to said fluid material outlet, and to said at least one fluid channel.

A rotary union comprising:
- a non-rotating union part disposed about an axis;
- a rotating union part disposed coaxially about said non-rotating union part, said rotating union part being matingly engageable with a rotating device rotatable about said axis, said rotating device being disposed about, and supported by, a shaft and having a fluid channel disposed therein;
- and,
- a fluid passage disposed within said rotary union, said fluid passage comprising:
- a fluid material inlet disposed upon a surface of said non-rotating union part;
- a first portion in fluid communication with said fluid material inlet disposed within said non-rotating union part;
- and,
- a second portion disposed within said rotating union part and having a fluid material outlet disposed upon a surface of said rotating union part;
- wherein a fluid is communicatable through said fluid passage from said fluid material inlet, through said first portion disposed within said non-rotating union part, into said second portion disposed within said rotating union part, to said fluid material outlet, and to said fluid channel disposed within said rotating machine part;
- and,
- wherein said non-rotating union part and said rotating union part are coaxially disposed about said shaft, said shaft being supported by a support bearing, said rotary union being disposed at a position between said support bearing and said rotating device.
