Double sling effect mechanism.

Lately I was thinking about double sling effect inertial centrifugal and inertial force generator. It will consist of two contrary rotating masses; those masses will be guided by a linear bearing with welded short rods with double ball bearings. The masses will be moving along guided rods. The entire system will be rotate on egg shape external rims to obtain maximum force difference between two up and down position. The masses will be synchronized and, in each loop, will be passing by each other two times one time on the bottom and one time on the upper position. This system is not entirely balanced and to full balance there will be needed three such a generator placed on the corners of equilateral triangle. The system is not equipped in counterweights and the masses will be given away their full centrifugal force on the external rims. The centrifugal force is maximal in upper position in the while that both masses will be passed by each other and minimal in bottom position. This system is not finished this is only the scheme of the aim system, which will be developed in further time.

In the attached drawing the system is in lower position where the force is minimal. To solving is the question of delivering the external mechanical energy from the electric motor. I added the ball bearings on the separate shafts because they will be rotate in opposite direction. There was no way to balance the system by placed the generators in coplanar plane, so they are placed one by one. There was an opportunity to place them side by side, but I decided to place them in this way to obtain more closed system for the reason of delivering the power from electric motor, but this question as is seen is still to solve. The side parts of rims are close the main shafts so the masses hardly can pass between the rims and the main shafts, the enough distance is about several millimeters.

This system is an inertial propulsion attempt. 

I also add the animation form YT.
