DESCRIPTION OF THE INVENTION
The invention relates to the field of mechanics, namely to methods for accumulating the mechanical energy of rotational motion, and can be used in a variety of electromechanical devices comprising flywheels, particularly in the energy inertial accumulators.
Commonly known method of mechanical energy accumulation rotary motion [1] consists in that the inertia flywheel accumulator unwind about an axis perpendicular to the plane of rotation of the flywheel and flywheel to which a main central axis of inertia. The disadvantage of this method of energy storage is incomplete use of the inertia of the flywheel, t. E. Non-use of its inertia on the other two axes of inertia in the rotational motion, which reduces the energy density flywheel while limiting its angular velocity.
Known and the method of accumulation of mechanical energy [2] which is to some extent eliminates the disadvantage of the well-known (traditional) method of energy storage [1] According to this method, the flywheel inertia battery unwind around the two intersecting perpendicular axes passing through the center of the flywheel masses, and are for the flywheel main inertia axes. However, a significant disadvantage of this method of energy storage is occurring during the rotation of flywheel inertia unacceptable load on the battery support bearings in the radial direction (the dynamic unbalance of the rotating flywheel).
The purpose of the present invention to eliminate these drawbacks, ie. E. Unloading bearings inertial battery in the radial direction while maintaining the advantages of the prototype [2] with respect to the known process for energy storage [1]
The goal is achieved by a particular arrangement of the flywheel in the gimbals. The symmetry axis (own axis of rotation), a flywheel at an angle to the axis of rotation of the gimbals (second flywheel axis), wherein for a given ratio of the angular speeds of the flywheel moment of inertia of the flywheel forces along the axis perpendicular to the axes of rotation is zero.
METHOD implemented as follows
Balanced flywheel having one degree of freedom (rotation around the axis of symmetry), placed in a gimbal and unwind at the same time around the two intersecting at the center of mass of the flywheel axes: an axis of symmetry (own axis of rotation) of the flywheel and the rotation axis gimbal (second flywheel axis of rotation) passing through the center of mass of the flywheel; thus, unlike the prototype method [2] symmetry flywheel axis feature does not at 90 o to the axis of rotation of the gimbals, and at such an angle, wherein for a given ratio of the angular speed of rotation moment inertia of the flywheel forces along the axis perpendicular to the axes of rotation is equal to zero, ie. e. the angle at which a pair of gyroscopic moment forces (radial bearing supports the dynamic responses of the flywheel) is zero. In addition, the specified requirements to the flywheel, untwisted the proposed method in comparison with the flywheel is untwisted by the method of prototype, had at least no less energy density, are, as they should relate the principal moments of inertia of the flywheel.

The drawing for explaining the essence of the invention schematically: |
Let us explain the essence of the invention.
Let 1 2 angular speed rotation of the flywheel around the intersecting point O of the axes 3 and 4, respectively;
J z principal moment of inertia on the axis of symmetry OZ flywheel;
J x, J y principal moments of inertia axes OX, OY respectively, where J y J x flywheel effect of symmetry.
The conditions under which the gyroscopic moment of the couple of forces (reactions 
) Is equal to zero, ie. E. The condition of discharge bearing supports inertial battery in the radial direction.
Application of the Lagrange method yields the following equation of the equilibrium state of the flywheel relative to the axis OK: 
where L is the distance between the points of application of force (See Figure 1..); 
angle between the axes 3 and 4.
From this expression it follows that the reaction R bearing supports zero in two cases:
when q 0 o (this case corresponds to the conventional method by means of energy storage flywheel rotation around one axis only);
at 
Thus, the condition for determining the vanishing of the gyroscopic moment of couple is the essence of the invention is an expression (1). In this case from the resulting expression that
1) dynamic balance of the rotating flywheel is the case at any stage of the flywheel operation (at the promotion of storage and return power to the consumer), if 1 / 2 = const;
2) the specific energy of the flywheel, untwisted the proposed method will not be less than the specific energy of the flywheel, untwisted by the method of prototype, if
J 1 / J 2> 1 2 + 1.c.
