Abstract

SUMMARY OF THE INVENTION: upon rotation of an object, due to the presence of kinematic coupling between it and the housing 2, the latter is also rotated at half the speed. The energy carrier enclosed in the support also moves in space synchronously with the housing 2. Such a movement of the energy carrier loop leads to the absence of its twisting at any number of revolutions of the object. 2 ill.

Description

fs / g 1

The invention relates to the field of electrical engineering and can be used in antenna devices, electrical devices, devices using flexible optical fibers, pneumatic-hydraulic paths, etc. for transferring energy from a stationary object to a rotating one,

Contact columns are known for powering a rotating object using sliding contacts or contacts with liquid conductors. These devices have low noise immunity, are structurally quite difficult to operate and, in addition, only transmit electrical signals, but not light or pneumo-hydraulic ones.

Devices are also known for contactlessly transferring electricity from a stationary object to a rotating one within a limited range by means of a flexible cable.

A known rotation mechanism of the antenna, providing power to an unlimitedly rotating object (prototype), comprising a housing mounted for rotation on a fixed base, a first bevel gear mounted on the base, a second bevel gear mounted in the housing for rotation, interacting with the first and motionlessly connected to the antenna, and a flexible current lead (cable) located inside the housing.

The disadvantages of this device include the fact that in order to prevent the cable from twisting, the object is forced to double rotation: rotation around the azimuth axis (together with the body) and rotation around an axis perpendicular to the azimuth axis. This second rotation limits the operational capabilities of the device, allowing the use of axisymmetric antennas only.

The aim of the invention is to expand operational capabilities by providing power supply to objects having unlimited rotation on one axis,

This goal is achieved in that the device comprising a housing mounted on a fixed base rotatably, a planetary gear including a first gear fixed to the base, a second gear fixed to the shaft of the rotating object, and a flexible energy carrier, fixed at one end to a fixed base, and another - on a rotating object, laid with the formation of a bend, placed part of the length in the cavity of the body and passed through the hole of the latter, is equipped with a block ohm of two gears mounted on a common shaft, interacting with the first and second gears, the latter are placed along the axis of rotation of the object, while the block shaft is mounted to rotate in the housing, and the part of the energy carrier located outside the housing is laid with the formation of an open loop placed outside the sweeping surface of a rotating object, and the cable feed direction to

rotating object and base are the same.

In FIG. 1 presents a schematic drawing of the proposed device; Fig. 2 is a diagram of cable motion.

The device comprises a fixed base 1 on which the housing 2 is mounted rotatably. In the housing 2, a rotating object 3 is mounted rotatably in the form of two flat

antennas 4 connected by a beam 5 mounted rigidly on an axis 6 with a gear flange 7. A flexible energy carrier 8 is rigidly fixed at one end to a fixed base 1 and the other to a rotating object 3,

while part of the length of the energy carrier is placed inside the housing 2 with the formation of a bend. The energy carrier is passed through an opening 9 in the housing 2, The other part of the length of the energy carrier is located outside the housing 2,

laid with the formation of an open loop in the supporting support 10, rigidly fastened to the housing 2. In the support 10, the energy carrier is laid with the possibility of free rotation around its longitudinal axis.

The housing 2 and the rotating object 3 are connected kinematically (with a gear ratio from the second to the first equal to two), a planetary gear transmission, consisting of a gear cut 11, made on a fixed base 1, a block of gears 12 and 13, the axis 14 of which is installed rotatable in the bracket 15 mounted on the housing 2. The energy carrier 8 in the support 10 is located outside the surface of the omelet 0 of the rotating object 3, while the direction of supply of the cable to the rotating object and the fixed base coincide.

5 The device operates as follows.

When the object rotates, due to the kinematic connection between it and the body 2, the latter is also rotated at half the angular velocity. The energy carrier enclosed in the support 10 also moves in space synchronously with the housing 2. Such a movement of the energy carrier loop leads to the absence of its twisting at any number of revolutions of the object. This is explained as follows. Let us have a segment of energy carrier installed in a carrier with the possibility of rotation around its own longitudinal axis. We give the end A the angular velocity ω. Then the end B will rotate at the same speed but in the opposite direction (a) without twisting relative to the longitudinal axis. Let us give the whole system (a carrier with an energy carrier) the angular velocity (-ch) around the O-O axis. Then the end A of the energy carrier will become stationary (that is, it will become possible to fix it on a fixed base), the carrier will rotate with speed (), and the end B with speed (-2a)). Thus, an object rotating unlimitedly can be connected by a flexible energy carrier to a fixed base, with no cable twisting.

Using the proposed device makes it possible to simplify and reduce the cost of all-round viewing devices, and also makes it possible to transfer liquids and gases from a fixed object to unlimited rotation without stuffing boxes and other sealing devices.
