Definitions
- the invention relates to a cycloidal propeller according to the preamble of claim 1.
- a cycloidal propeller is described in Voith special print 1803, "The construction of today's Voith-Schneider propeller", (Special print from Voith “Research and Construction", issue 18, Page 3, May 1967) and Voith-Druck 9.94 2000.
- the control point star enables a structurally relatively simple determination the coupling of the wing drive linkage to the ball bushing of the Joysticks.
- the formation of the parallel guide halves offers with two joint rods, which are opposite in relation to the halves extend and each of which is fixed but rotatable on the rotor body stored diametrically opposite each other, the possibility that Wing angle curve due to the length ratios of the joint rods in influence in some way and thus also the hydrodynamic Characteristics of the propeller. This property can be used with propellers any number of wings can be used.
- the linkage of the parallel guide also only contains rotating bearings have little wear and are easier to control than sliding bearing elements.
- the propeller blades 30a, 30b, etc. are on the wing circle 23 evenly distributed.
- the associated drive linkage of the kinematics is with 20a the swing arm, with 21a the coupling and with 22a the coupling rod, the engages the respective drive lever 23a, which with the respective Propeller shaft of the single wing is connected.
- the Wing drive linkage now engages with the coupling on the Control point star 14 on, and that is the corresponding hinge in each case attached to an extension 25a, 25b, etc. It can be seen from Fig. 2 that this control point star at the bottom of the joystick 17th located ball bushing 16 is attached.
- wing drive linkage in particular the so-called coupling 21a, etc.
- the drive drum 37 of the rotor body then continues in further, essentially rotationally symmetrical parts, the carry the thrust bearing and finally with the ring gear of the drive gear of the propeller are connected.
- the fixed swivel of the Parallel guidance consisting of rods 1, 2 and 1 ', 2' and the Connecting rod 3 is 5 '(see also pivot 5 in Fig. 1) and on the top wall 38 of the rotor body. This is a exact parallel guidance, but here there is a certain disadvantage exists when an imbalance is generated by the parallel guide.
- Fig. 3 is another variant of the parallel guidance with the individual Rod members 7, 8 and 7 ', 8' shown.
- the swivel joints on the rotor body are designated here by 9 and 9 '.
- the connecting rod 11 The two halves of the parallel guide are shown here in such a way that they are in principle in the middle the two diametrically opposite rods 8 and 8 'of Parallel guidance by means of pivot joints 13 and 13 'connects and under Possibly below the joystick, therefore the ball bushing runs. But it can also be the stick or the stirrup Include ball bushing. It can also run below the rotor body be bow-shaped and V-shaped.
- Fig. 1 The small, dash-dotted circles shown in Fig. 1 give the Freedom of movement of the joints located on the control point star Wing kinematics when adjusting the joystick (adjustment of the Eccentricity).
