 ..one - , .

The invention relates to machine-building: HHKS and more specifically to the field of astronomical instrumentation and can be used when designed in high-frequency large-sized optical and radio-optical systems that require a static balance of the MOBILE aei Bcan systems.

A device for statically balanced mobile telescope satellites is known, containing a base, a mandrel for securing a clamp, mounted on the base with a turn around its base, an equilibration mechanism, holding a hilt, and an addendoment on its body. .

The device is equipped with a support element. a volume and a t coupling that interacts with it, one end of which is connected to the other 20 end of the npyxfmti, and with a lever rigidly connected to H tenaeM, the supporting element is positioned so that its interaction with the flexible coupling is:

The reference is at the intersection point of the vertical axis of the circle reference, the radius of which is equal to the distance of the correction axis to. The connection points of the flexible link with the growl volume Cl 3.

When the product rotates around an axis, the weight loads cause considerable de нед unacceptable for high frequency telesks.

A device for balancing large objects, containing a stand, a support mounted on it for fastening an object, a rotational drive of an object is known. The device is equipped with an intermediate support made in the form of a lever, one end of which is hinged on the frame, and the other is spring-loaded, and the ropak, suspended on i & nare. The main bearing is made in the form of a sector with a mixed center of gravity, the forming of which interacts with the roller C 2. .

In the TOL case, the compensation of deformations from the weight loads occurs due to the effect of the elastic element on the crustal axis. However, it is impossible to completely eliminate the deformation of the axis from the weight loads, since when rotating around an elevation axis, the force exerted on the axis should be almost unchanged, while the elastic element for balancing the rotating parts must change its length, which leads to an unlimited increase in length package. This device can be used in telescopes with alt-azimuth mount, but for other mount schemes, for example with alt-alt mount, a similar device for compensating the deformation of the second axis from the weight load is unacceptable, since the position of the second axis in space and the composition of the second weight loads vary. The telescope mount is known, containing a fixed base, on whose shaft the body is mounted, a telescope tube mounted in supports on the body axis associated with a static balancing device made as a counterweight by means of a lever 13 A disadvantage of the known telescopes is that. That they provide high accuracy of work only with small reflectors. With large reflectors, the metal consumption of the structure increases significantly, the weight of counterweights (balancing devices) increases, and under the action of weight loads, the optical axis of the telescope is rotated due to bending of the body, which leads to a decrease in accuracy. The purpose of the invention is to increase accuracy, reduce weight and improve dynamic performance. telescope. The goal is achieved by mounting a telescope containing a fixed base, on the shaft of which a body is installed, a telescope tube installed in supports on the axis of the body connected to a static balance device, counterbalanced by solar, by means of a lever, in devices for static balancing a system of levers is introduced, kinematically hingingly connecting at least one of the supports of the housing axis with the counterbalance lever, the counterweight lever being pivotally connected to the housing. The drawing shows the mounting structure, which consists of a fixed base 1, on which a horizontal shaft 2 is mounted, on which a housing 3 with a bracket 4 made in the form of a goose is mounted in rotation. The housing axis 5 is installed in bearings 6 and 7, and the telescope tube 8 is rotatably mounted on the axis 8. The lever 9 of the balancing device, made in the form of a counterweight 10, is connected to the housing 3 by hinges and through systems of levers 11-13 7 axes 5. When the axes are out, you can connect the lever of the balancing device with both axle 5 supports or with other points where you need to compensate for the component of the weight load. In the position of maximum weight (imbalance, the counterweight 10 compensates for the weight imbalance of the product and, through a system of levers 11-13, acts on the eye of the bearing housing 7 with the force required to compensate for the weight load. The required force is achieved by selecting the lengths of the system of levers 11-13 and precise adjustment is achieved by changing the weight and the length of the counterweight lever. When the product to be balanced is rotated at an angle ct, the moment of unbalance of the product, the moment of counterweight, the weight component of the force that displaces the bearing 7, and the force acting Therefore, simultaneously with the balancing, compensation is achieved for the weight load on the bearing 7, i.e. the horn system 11-13 can be adjusted so that the mixing of the bearing 7 deformation of the body 3 og of the weight load equals the mixing bearing 6 at any angle oi. This increases the accuracy of the position of the axis when the telescope is rotated around the horizontal axis of rotation, and the rigidity of the bracket 4. must ensure the accuracy of the telescope only when inertia loads are applied, The slides are insignificant compared to the weights. The proposed telescope design not only improves the accuracy of the product, but also significantly reduces its weight, bearing static moments and drive power, which improves the telescope's overall dynamic characteristics.
