The second stage CR2 design is analogous as CR1 and includes two cycloidal discs with [z.sub.3] = 21 lobes each and ring gear with ring gear pins/rollers [z.sub.4] = 22, Fig.
Since its initial development in the 1920s by Professor Frederick Kurt Kirsten of the University of Washington, the cycloidal rotor concept had largely been abandoned after further studies, owing to the complexity of the aerodynamic analysis required and the existence of insurmountable structural problems.
The variables which define the modified cycloidal path of hip are [r.sub.x], [r.sub.y], [x.sub.hi], and [y.sub.hi]; where [r.sub.x] and [r.sub.y] are the span and height and ([x.sub.hi], [y.sub.hi]) is the starting coordinates of cycloid.
Considering that [z.sub.3] = [z.sub.2] + 1 (a property specific to the cycloidal gear pairs with rollers), the following values (see also Fig.
The two cycloidal directories of the flanks must be generated with different curvature radius in order to realize the camber of the teeth.
An RV drive is densely constructed with almost all of the space within its envelope occupied by steel or iron, It is a cycloidal gear system with many of its parts precisely ground to size and held rigidly in place by a solid structure n so rigidly that every moving part can only move in its intended path.
Calculations show that the propagation should follow the changing location of the tidal bulge, creating cycloidal loops shaped just like those seen on Europa.
The larger units also have the added advantage of being able to accept particle topsizes of up to 80 mm, depending upon the feed inlet configuration (tangential, involute or cycloidal).
Each tug is powered by two General Motors EMD diesel engines that generate a total of 3000 hp and turn two Voith Schneider cycloidal propulsion units.
* reengined (converted from direct-drive cycloidal to quieter, more reliable diesel electric engines with azimuthing Z-drives),
