WANKEL-Engine

[Miko]

Hi all.. I was trying to animate this special kind of engine but without good result. The main problem isdefine the generating (hobbing)connection between pinion gearand special triangular gear with internal gearing. I was trying to> define cam follower, cam connection,general motion with combination of cylindrical and planar motion.. but still without any result

.. And here is another thing what Ido not understand> On this site http://www.keveney.com/Wankel.htmlyou can see gif animation of this motion but when Iwas trying to create same assembly and define the mentionedconnectionsIhad many defectsduring motionanalysis (kinematics). I dont understand how can works this arms which are painted with blue color. I thought that I am able to create pinion and main gear assembly and than just create after motion analysis the TRACE CURVE of one vertex of triangular part but it doesnt works because there must be defined bearing connection (I think). Here you can see more pictures of my assembly:

Here you can see my assembly but housing is only fiction because I dont know how exactly it can look like.

Also you can see the extruded surfaces as main cylindrical gears shapes (I used it for cam connections).


Here are all parts of my assembly>

Helo ecosgriff! For housing you need trohoida and how you did the rotor.

mckrajnc1234,


Housing is not part of the mechanism. It can be adjusted where ever it best fits.
