The invention relates to the field of rocketry, namely to devices for controlling the aerodynamic surfaces of supersonic missiles. This device can be applied in similar conditions of work units in mechanical engineering.

The closest the set of essential features is a device presented by the RF patent №2258895 C1, F42B 15/00, 2004, which was adopted by the authors for the analogue.

The specified device relates to the field of weapons, namely the rocket technology. It is a block of the steering actuator is controlled projectile, comprising a shaft, a lever mounted on the shaft, a steering unit mounted in the housing shell, the stem of which is pivotally connected to the lever, handlebars, located on the axis and mounted in bearings.

The disadvantage of this device is the inability to install it in the body of the rocket with small volume to accommodate the drive shaft of the steering due to the significant longitudinal shaft size, and the impossibility of its use in conditions of high loads.

The aim of the invention is the creation of a steering gear unit of a rocket operating at high aerodynamic loads, the small size of the shaft.

To achieve these goals, the steering gear unit of a rocket, consisting of aerodynamic �poverhnosti, a shaft installed in the body of the rocket rotatably and rigidly connected to the aerodynamic surface, a lever rigidly mounted on the shaft, a steering Assembly connected to the body of the rocket and is pivotally connected to the lever, the mechanism of rotation of the aerodynamic surface is in the form of a shaft, pivotally connected with two rigidly interconnected rings, rigidly mounted in the body of the rocket. The shaft is made a groove, and the ring is conical raceway, forming with the groove of the annular cavity. Inside the cavity are spaced evenly around the circumference of the rollers, with each successive roller is perpendicular to the previous one, and between the rollers installed a separator.

Fig.1, 2 shows the structure of the proposed unit steering rockets.

Block steering gear consists of a shaft 1, the aerodynamic surface 2, is rigidly fixed on the shaft 1, the steering Assembly 3, the rings 4 and 5, is rigidly bonded to each other, installed in the missile body and pivotable relative to each other cool bolt 6 and the collar 7, the rollers 8 and separators 9, 10. The stem 11 of the steering unit 3 is pivotally connected to the lever 12 axis 13.

In the annular cavity formed by the groove 14 on the shaft 1 and the tapered raceways 15 and 16, these rollers 8 in such a way that every� subsequent roller is perpendicular to the first. To avoid misalignment of the rollers between them are the separators 9 and 10. Separators have two surfaces on opposite sides, which they are in contact with the rollers.

The device operates as follows. The stem 11 of the steering unit 3 is moved translationally. The translational motion of the rod 11 is converted into rotational movement of the shaft 1. The shaft interacts with the rollers 8, each of which moves along one of the tapered surfaces 15 or 16 on one of the stationary rings 4 and 5 and the opposite conical surfaces of the groove 14 made on the shaft 1. Thus, with a single row of rollers has the ability to absorb the load acting on the aerodynamic surface.

The proposed technical solution allows to realize a design of a steering gear unit of a rocket operating at high loads, the small size of the shaft.

The steering gear unit of a rocket, consisting of an aerodynamic surface, a shaft mounted in the body of the rocket rotatably and rigidly connected to the aerodynamic surface, a lever rigidly mounted on the shaft, a steering Assembly connected to the body of the rocket and is pivotally connected to the lever, characterized in that the rotation mechanism of the aerodynamic surface is in the form of a shaft, a swivel connection�tion with two rigidly fixed between the rings, rigidly mounted in the missile body, the shaft is made a groove, and the ring is conical raceways forming an annular groove in the cavity inside the cavity are spaced evenly around the circumference of the cylindrical rollers, with each successive roller is perpendicular to the previous one, and between the rollers installed separator.
