Known girevoy GR containing a rotating flywheel connected through a mechanical transmission with a pair of wheels.

In gyrobase the flywheel spins at stops the air motor, and the flywheel through the clutch is disconnected from the shaft. In gyrobase provided by a stepped regulation of speed by incorporating one or other transfer in-a-box speeds. Thus, girous equipped with a fairly complex transmission, so its reliability is not high enough. This flywheel clutch attached to the drive shaft, without any control of torque of the flywheel.

A clutch and gearbox. The transmission includes connected with a pair of wheels of a single-stage gearbox, the associated rigid coupling with the shaft, on which is placed the flywheel. Adjusting the torque in the transmission is not provided, which facilitates the transmission and increases its reliability. The flywheel is made in the form attached to the shaft and forming a trench two disks on the external surface through which the rolling elements held by the separator, based rim in the groove between the shaft and the rim is placed closed elastic toroidal shell associated with a controlled pressure source.

The drawing shows the proposed girous, longitudinal section.

On the shaft 1 through the holes worn two disks 2 and 3, forming a trough. Discs 2 and 3 mounted on the shaft 1, for example, by welding. To the outer surface of the disks 2 and 3 are attached by welding separators 4 rolling elements such as rollers. On rolling element separators 4 relies rim 5. Disks 2 and 3, the separator 4 with the rolling bodies, the rim 5 form a rolling bearing.

In the groove formed by the disks 2 and 3 are placed closed elastic toroidal shell 6. The shell 6 by means of synthetic glue is attached to the shaft 1 and the disks 2 and 3. To the outside of the shell 6 PR is her side of the shell 6 made hole 8, communicate with connected to a pressure source channel 9, is made in the shaft 1. The pressure source may be a tank of compressed air or pump, the feed liquid. The outer surface of the rim 5 is made in the shape of a trench, in which is placed a closed elastic toroidal shell 10 with the protector 11. The protector 11 to the shell 10, and the shell 10 to the rim 5 is attached with glue. Through separators 12 with the rolling bodies of the rim 5 based rim 13. In the side of the shell 10 and the rim 5 is made annular gap 14, hermetically covering the U-shaped annular rubber sleeve 15, which is connected via channel 16 with the tube 17 communicated with the pressure source. During rotation of the rim 5 of the cuff 15 is in contact with the rim 5, preventing air or liquid from the shell 10. While slightly abraded edge of the cuff 15 in contact with the rim 5. The rims 5 and 13 top and bottom are supported by the rolling elements (rollers) of the separators 18, thus excluding the offset of the rims 5 and 13 relative to the shaft 1. The flywheel can be provided with one or two extra rims, placed similarly to the placement of the rim 13 on the rim 5. The flywheel is placed in the housing 19, provided with a hinged lid 20.

Girous exploitive. When the protector 7 is not in contact with the rim 5. In the shell 10, the air (or water) under pressure, and the protector 11 with a high coefficient of friction in contact with the rim 13. When open, the lid 20 to the side surface of the rim 13 is fed to the friction pulley mounted on the shaft of the air motor, and is rotated flywheel, for example, up to 2000 rpm In the shell 6 is air (or water), the shell 6 is inflated, the protector 7 is in contact with the rim 5 and the shaft 1 are reported the torque stored all the flywheel. Is transmitted via the gear on the wheel a couple of girolata, which moves off. This flywheel is a substantially continuous drive torque which is equal to M1 FR, where f force applied to the outer surface of the rim 13, R the distance from the surface of the rim 13 to the center of the shaft 1. If you want to change the torque on wheel pair, and, consequently, the speed of girolata, reduce the pressure in the shell 10, with the rim 13 starts to rotate independently of the rim 5. The torque delivered by the flywheel is equal to M2CL, where the force applied to the outer surface of the rim 5, L is the distance from the surface of the rim 5 to the center of the shaft 1. As L < R, M2< M1. Olesno couples need to re-create the pressure in the shell 10, and to stop hiromasa to reduce the pressure in the shell 6.

Thus, by periodically connecting to the shaft 1 rotating rims, adjust the torque on the wheel pair and the speed hiromasa.

The increase in the number of rims allows you to adjust the speed hiromasa more smoothly and in a wide range.

In the present gyrobase simple transmission, no clutch and gearbox. The speed adjustment hiromasa by changing torque of the flywheel by dividing it into separate rotating one relative to the other annular rims. This increases the reliability of the transmission due to its simplicity.

SUBSTANCE: the group of the inventions is pertaining to the field of transport mechanical engineering and may be used for production and transfer of the mechanical oscillations and for movement of the transport vehicle in the preset direction. The method of production of the directional mechanical oscillations provides for running around by the rotating inertial element of the elliptical running track with contraction of this element to it. The movement of the inertial element on the elliptical running track is exercised in respect to the axis superimposed with one of the focal points of the elliptical trajectory chosen as the main focal point. The used inertial element is balanced. The method of transformation of the directional mechanical oscillations into the unidirectional discontinuous translational movement provides for interaction among themselves of two masses of the system, one of which is the inertial mass rotating about its axis and simultaneously is moving in respect to the other mass along the elliptical trajectory with its resilient contraction to the running track of the ellipse providing the system with the directional mechanical oscillations. The used system is unbalanced with the center of masses coinciding in the static condition with the center of gravity of this system and with one of the ellipse focal points. The movement of the system is exercised by the successive step relocations in the moments of the impulse action of the inertial forces along the long axis of the ellipse of the maximal value disturbing force directed from the main focus point in the movement direction.
