This video is garbage! Ridiculous waste of time. Here is an actual video explaining it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oUVE2PIV5_k.html
In most cases yes, each drive motor requires two hoses; one for the supply and one for the return. However, it can vary by manufacturer and equipment size. Thanks for checking out our video!
I can barely understand this ''magic". But this is fascinating. The amount of effort that needs to be put into creating something like this is truly amazing.
So if I understand correctly, there's a... chamber? of sorts that goes full circle so that no matter how much it rotates, the fluid/gas will always be able to reach the exit?
You are correct! Rotary unions are also bidirectional meaning the media can travel into the shaft and out the housing or vice versa. For it to all work correctly the proper sealing technology must be used. Media type, temp, pressure, duty cycle, etc. all play a big role.
@@DstiRotaryUnions Thanks for confirming it. I was curious how it works since I use a machine with this kind of thing at my job (it has four entrances and exits instead of two, but the intakes are all at different heights)
@@urbanberndtsson You're welcome. If you check out our website we have standard rotary unions with 1 - 24 passages. www.dsti.com/rotary-unions/standard/
It was very clear how it is able to turn continuously... but it was not apparent at all why it turns in the first place. I assume these also include a kind of drive mechanism to make things like excavators swivel in place?
Rotary unions themselves do not have any sort of drive mechanism. Excavators have swing drive bearings and hydraulic motors that rotate the cab. This allows the mounted rotary union to rotate as the cab rotates. Hope this helps and thanks for checking out our video.
@@gregwoolsey2215 They don't need to in that application, as they don't rotate (relative to the cabin) but would usually act upon an outer ring around the bearing via a gear drive. This could however be directly controlled (hydraulically) in the body from the cab with a rotary union.
"Not only was this a great opportunity to support our community and the growth of the Robotics Team, but it also provides an experience as close to "real world" engineering as a student can get," says DSTI Engineering Manager Phil Engelman.
