Talk:Conical screw compressor

Notes of first author and possible deletion

This article was created to provide information on an emerging technology, even though it is not clear whether it will be successfully adopted as a useful technology. It is new, under-developed, and there appears to only be one company working on development (they appear to hold exclusive patents) but it is clear that it is an operational technology and at least somewhat effective, commercial units have been produced although the existence of these has not been mentioned in the page since all current information is self-reported by the producer. If others think this article does not have sufficient content to stand on it's own then it should probably be moved to the rotary-screw compressor page, which I have already added a basic description to.

The lack of references is a problem, I have added a reference to a second study, but it is still connected to Vert Rotors, I was surprised to find there is little else. Others I found were dealing primarily with the modelling of the physics and rotor shape. I see no reason to doubt the functionality of the technology but the lack of more independent sources makes me reluctant to repeat many of the claims. I have altered some of the language of claims that are factual in theory but lack independent confirmation that physical devices will perform in those ways.

Also I the only other page I have created was on a much more established technology so I wasn't quite sure how to approach this one, any advice on method, references, language, and such would be much appreciated. --MasterTriangle12 (talk) 05:11, 6 February 2020 (UTC)

Thanks Verlierer, nice to see the technology advancing. MasterTriangle12 (talk) 18:38, 9 June 2020 (UTC)

I find the description of the geometric concept succinct, easy to understand, and of general use/interest beyond any specific company's product. At least, it helped me make a practical connection that I am putting into use in my own R&D.

Only one minor nit:

"A gerotor, of which the CSC is a conical spiral extension of the topology, just as a regular screw compressor is a spiral extension of the lobe pump topology."

This leaves out an important detail; because of the angular offset and beveled meshing, a linear/helical extension of a gerotor won't mesh properly. The tooth profile must be extended using (eg) spherical helical geometry like any other beveled gearset. 64.223.70.82 (talk) 13:39, 24 August 2023 (UTC)

Ah, thanks! Yeah the spherical requirement is obvious now that I think about it. I have clarified the description a little to indicate that topology description is illustrative but not exact, but it would be nice to add an exact description. Is just wrapping the gerotor form into a spherical geometry with linear scaling to the spherical radius an exact solution to generate the right geometry? I'm not intimately familiar with complex geometry, especially of gerotors and meshing and such, but I'm guessing the scaling must be linear and the twist can be arbitrary?

Either way, if your R&D is of a CSC-type structure I would be keen to talk about it since back when I made the article I had an idea for how to achieve the last few microns of machining for the assembly to get a perfect fit and I have always wondered if it could be practical.
