The invention relates to a device for converting the motor or other power sources to work, providing traffic devices, such as cars, tractors, agricultural machinery on earth, under the earth, and can be used in and under water. Known mover in the form of a wheel gear drive axle vehicle (patent No. 2170863, CL VC 17/32, epubl. 1999)containing a planetary transmission comprising a sun gear mounted on shafts, Stellite, located in a drive rod having a Central hole, and the root of the gear cover pinion carrier thrust washer, stop the sun gear, carrier is made with a locking groove and provided with an adjusting nut and a lock washer, and adjusting nut are made with locking grooves and placed in the Central hole of the carrier, made the screw and retaining washer are made with external and internal mustache, and the outer condition is placed in the locking groove carrier and the locking groove of the adjusting nut, in addition, the cover carrier is made with ribs, pressing the lock washer to the end surface of the carrier. A disadvantage of the known device is the design complexity and limited technological capabilities when using the device is the primary objective for movement on the water and under the water. A technical solution is achieved in that the propulsion coil is made in the form of a hollow cylindrical screw-shirts, mounted around the perimeter of the body of the transport device with the possibility of rotation around the body, and is made from strips of rectangular shape, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction on a cylindrical mandrel with education on the perimeter of the outside screw shirts spiral lines and spiral curved surfaces in the form of helical grooves concave shape relative to the symmetry axis of the screw-shirts with the centers of curvature of the outside coil of the shirt. According to the patent and technical literature technical solutions are not found, similarly declared that allows to judge about the inventive step of the proposed propulsion screw. The novelty is due to the fact that the driver of the screw along the perimeter provided with multiple helical surfaces in the form of a helical channels that give transport device longitudinal movement with great speed defined by pitch spiral surfaces. For example, when the step helical surface of the conical helical shirts, equal to 100 meters over one of its turnover, the transport device can move 100 meters, at a rotational speed of 10 rpm speed of the transport device can reach speeds of 600 km/ h. The novelty lies in the fact that the placement of the propulsion around the perimeter of the casing ensures high efficiency. The novelty lies in the fact that due to the outer spiral surfaces of double curvature resisting movement of the transport device is reduced, it increases the speed and reduces noise, which in combination with the specified geometric elements of helical shirt improves its characteristics. Novelty also lies in the fact that the placement of the propulsion around the perimeter of the transport device and the implementation of its cylindrical provides a vehicle acoustics and reduce drag. The novelty of the invention lies in the fact that the helical shirt along the entire length has a variable smooth cross-section that reduces resistance during movement of the transport device and its quiet. Novelty is seen that the screwing of the screw shirts made multiple channels curvilinear shape, which increases traction power and propulsion, increases the speed and reduces noise. Novelty also lies in the fact that the perimeter of the screw shirts formed helical surface with a constant width along the length, which reduces the resistivity is our actions movement of the transport device. Novelty is also due to the fact that the step spiral lines on the perimeter of the screw-shirts from the inlet to the outlet constant, which reduces the resistance of the transport device. Novelty is also due to the fact that the mover along the perimeter made of folded in a vertical plane and sequentially interconnected along the length of the screw shirts rectangular strips, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction with the formation along the perimeter of the helical shirts spiral lines and spiral surfaces concave shape with the centers of curvature of the outside helical shirts that facilitates the movement of the transport device and increases the speed by reducing the resistance of the environment in which moves the transport device. The invention is illustrated by drawings, where: figure 1 is a mover in the form of a helical shirts, General view; figure 2 is a section a-a in figure 1; figure 3 is a view of a strip of rectangular shape after twisting its ends about a horizontal axis O1-O1; figure 4 is a view of a strip of rectangular shape after twisting it on a cylindrical mandrel; figure 5 - section b-B in figure 4; figure 6 - section b-B in figure 4 with a combination of the two edges with erotic in the screw strips of rectangular shape; figure 7 shows a transport device, such as a torpedo with the mover of the proposed design, General view; Fig - top view figure 7. The driver of the screw (Fig 1 and 2) made in the form of a hollow cylindrical screw 1 shirt. A hollow cylindrical screw-shirt 1 (figure 1 and 2) with inlet 2 and outlet 3 are made with outer curved surfaces 4 a concave shape relative to the axis of symmetry of the cylindrical screw 1 shirt with the centers of curvature of the outside cylindrical screw 1 shirt. A hollow cylindrical screw-shirt 1 (figure 1 and 2) is made of strips of rectangular shape, for example 5, 6, 7, 8, 9, 10, 11, 12, twisted along a helical line in the longitudinal direction (figure 3) and curved in the transverse direction (figure 4 and 5). Each of the bands 5, 6, 7, 8, 9, 10, 11, 12 twisted in the longitudinal direction relative to its own axis of symmetry O1-O1for example, the strip 9 figure 3 with the longitudinal side edges 13 and 14, which are fixed in hot or cold one end and rotated the other end of the strip in a predetermined direction. Twisted thus the strip is positioned on a cylindrical mandrel 15, as, for example, in figure 4 the strip 9, and bent so that the edges 13 and 14 of the strip 9 is least in the transverse direction along the spiral lines. When this strip 9 Defoe is programmed and either removed from the mandrel, either fix it in the deformed position. Processed in the same way the rest of the band 5, 6, 7, 8, 9, 10, 11, 12. Further deformed so strip 5, 6, 7, 8, 9, 10, 11, 12 placed on the mandrel 15, for example, as figure 6 lanes 9 and 8 combine longitudinal edge, for example edge 13 of the strip 8 with the longitudinal edge 14 of the strip 9 and is connected by known methods, for example by welding. Figure 7 and 8 presents the transport device, such as a torpedo with the propeller 16, made in the form of a hollow cylindrical screw 1 shirt, mounted around the perimeter of the housing 17 of the transport device, such as a torpedo, comprising a steering group of 18 and a head device 19. A hollow cylindrical screw-shirt 1 is mounted around the perimeter of the housing 17 of the transport device, without the possibility of axial movement relative to the housing 17 of the transport device and is equipped with a device for making hollow screw 1 shirt rotation around its own axis and the hull of the transport device (not shown). Moving the transport device is performed when the rotation of helical shirts 1 thruster 16, which when the rotation is screwed into the layers of the medium, for example water, and imparts longitudinal movement to the casing 17 of the transport device with the speed, determine esamai speed coil 1 shirt. The housing 17 of the transport device, such as a torpedo, when the movement retains its position with the steering unit 18. Technical appraisal and economic benefits propulsion screw arise due to the implementation of screw propulsion in the form of a hollow cylindrical screw-shirts, mounted around the perimeter of the body of the transport device, and create on its outer surface unidirectional helical lines and spiral surfaces in the form of channels curvilinear forms that not only are screwed into the layers of water, but also provide, however, silent movement of the transport device with great speed in the longitudinal direction. The driver of the screw is made in the form of a hollow cylindrical screw-shirts, mounted around the perimeter of the body of the transport device with the possibility of rotation around the body and is made from strips of rectangular shape, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction on a cylindrical mandrel with education on the perimeter of the outside screw shirts spiral lines and spiral curved surfaces in the form of helical grooves concave shape relative to the symmetry axis of the screw-shirts with the centers of curvature of the outside screw-shirts.
