Machine Rotative à Piston Annulaire Tri Lobique

[tomsid]

this makes it look better, but it still has end plate friction and the round part of the rotor must rub on the outer ring.

i am still thinking of how to reduce both of these, and think it may be possible.

thanks again tomsid

bonjour
voici un brevet similaire au dessin de tomsid
avec l'équation de la courbe décrite par l'extrémité des palettes

[pascal HA PHAM]

Bonjour à tous,

gros travaux de mon côté sur le concept VIPP de TOMSID et hier soir j'ai pu établir avec certitude l'équation polaire :



c'est du manuscrit mais je pense qu'il est intéressant de graver dans le marbre cette équation polaire.

d'autre part, j'ai pu établir la matrice des points X et Y par degré sur un cycle de 360°.

La réalisation paramètrée avec une précision du milième de mm pour le profil de stator de chambre, et selon les paramètres choisis (DEC, R, PAL, VAR) est désormais acquise.

dessin du fameux profil obtenu à l'ordinateur



avec :

DEC = 10 mm
R = 10 mm
PAL = 60 mm

la matrice en 6 colonnes des 360 points X,Y :

bonjour
voici un brevet similaire au dessin de tomsid
avec l'équation de la courbe décrite par l'extrémité des palettes
http://v3.espacenet.com/publicationDeta ... 5646A&KC=A

Bonjour et merci Bigeasy : c'est intéréssant ce lien

extrait du croquis de brevet avec l'équation polaire de ce brevet de 1967 :



le nom de cet inventeur :
Denis Antoine Lue Maurice Reyn (GB)

Sinon une vison informatique plus détaillée de la cinématique de TOM :



avec le cercle inscrit (points blancs) à l'intérieur du profil, on voit mieux que ce profil n'est pas circulaire

autres représentations avec maneton de villebrequin et demi palettes = une série séquentielle sur 1 demi tour & tous les 20° angulaires :

pascal

thank you for showing us your wonderfully interesting work.

one thing further interests me ,and it is somthing which i do not have an answer yet.

could the one vane rotor work with a circular housing ?

obviously the present rotor needs a figure of constant width, but is there a small mechanical alteration (say a cam or crank) that would make the housing a circle.

this will take much thought and may result in somthing completely diffrent.

i am working on this and i dont think there is a simple or quick answer.

Thanks again showing your math and insights in rotary engines.

yours tomsid

ps. i have a final thought .

we pursue elegant and symetrical rotors to try and find a good rotary mechnism. maybe the best rotary mechnisms are ugly and non-symetrical .

its just a thought

[tomsid]

there is a rotary engine by Fuchs

http://nowscape.com/renata/Fuchs_rotary_engine.htm

this can be configured to use the tsp type rotary drive



the housing is still a figure of constant width and not a circle.
sculpting the ends of the lense shape may make a circle but it will work the way it is.

i think this could be important but its not as ugly as i would like

tom

[tomsid]

hi

i have realised that this rotoray is better than i at first thought as it can be configured so the only friction is at the rotor tip.



this could make it like a two apex wankel. two apex wankels already exsist but i dont know their mechanisms.

yours tomsid

may japan see the sunshine soon

bonjour TOMSID :

j'ai re-travaillé les animations, la démonstration et sa siné qua non :

ANIMATIONS :
une demi palette

deux demi palettes en prolongement


DEMONSTRATION :



ZOOM sur la SINE QUA NON :



RESUME :

L'équation polaire du concept VIPP RVNC WV2 de TOM s'écrit définitivement :

VAR*SIN ((Pi/2) - Têta) = R*(1 + SIN ((Pi/2) - 2*Têta))

Suite de l'histoire ?

- Oui car il y existe un coefficient K , tout comme pour le BIPP RVCC, ce coefficient K étant le rapport entre le rayon d'évolution de maneton de vilebrequin et la longueur unitaire de demi palette = R / DP.
- et re Oui pour un éclaté de la machine avec les axes pignons et autre courroie crantée....
- et trois fois Oui car il va falloir maintenant analyser les nouveaux schéma de TOMSID,

Merci TOM...! le développement théorique de ce bel objet tourne un max !

NOTA :
Dans les animations du jour, le coefficient K = 6.

A suivre donc...
