The ring piston (40) is set in the cylinder (42) fitted by an annular chamber (43) for a liquid medium moving the ring piston.

Mechanical energy accumulator

Accumulator includes shaft on which four-rayed carrier is fixed and sun gear capable to rotate around shaft and free-wheel clutch providing unidirectional rotation of sun gear are installed. At the ends of four-rayed carrier axes are fixed on which rotatable satellite gears are installed. The satellite gears are engaged with sun gear. The satellite gears are mounted on axes with formation of cavities in which potential energy accumulators are accommodated. These accumulators are made in the form of springs wound around axes and attached by their ends to axes and satellite gears. Shaft is installed with possibility of axial rotation. At one its end, double-sided electromagnetic friction clutch consisting of cartridge with pads for contact and two half-couplings is installed: one half-coupling is rigidly connected with shaft, and the other one - with sun gear. Working surfaces of half-couplings contain electromagnetic coils and are installed with possibility of contacting with pad. The cartridge is connected with power-takeoff shaft. At the other end of shaft, friction clutch for periodical stopping shaft rotation and compression springs providing neutral shaft position are installed.

Intermediate gearbox of helicopter tail transmission

Driving (4) and driven (5) conical gear wheels is made integral with their shafts and installed among themselves with reversal of rotation. In the casing (1), each of gear wheels is mounted on two bearing assemblies. Area of engagement of gear wheel crown gears is located between front and rear bearing assemblies of shafts. The casing comprises front wall bent with upper part forward tilt according to position of gear wheels installed with specified angle between axes, and two covers (2, 3). In the boring of front wall lower part, roller bearing (6) of driving gear wheel (4) shaft front support is installed. In the boring at the inner side of lower cover, double-row ball bearing (10) of driving gear wheel (4) shaft rear support is installed. Inside the boring of casing in the front wall lower part, roller bearing (19) of driving gear wheel (5) shaft front support is installed. In the boring of lower cover, double-row ball bearing (22) of driven gear wheel (5) shaft rear support is installed.

Ball cageless bearing

Ball cageless bearing comprises an external (1) ring and an internal (2) ring with two raceways and collars on each of them, and rolling bodies in the form of balls (3). The distance between the conjugated points of adjacent raceways on each ring (1, 2) amounts to 0.731-0.866 of the ball (3) diameter. The internal ring (2) is made with a big collar (4) common for both raceways and set on the bearing symmetry axis, and with smaller collars (5) with bevels set on the side of outer end faces of the bearing.

Method to produce brake pad with noise protection

Method involves preparation of a frame body with one or more through holes. A damping layer is applied onto the prepared frame body and is covered by a metal plate fitted by folded elements in the form of edges or an edge. The edges or the edge are placed in the holes or the hole of the frame body. Moulding of a brake lining on the frame body is carried out with simultaneous moulding of the edges or the edge of the metal plate into the brake lining.

Hydrodynamic clutch controlled by filling change

Invention relates to controlled hydrodynamic transmissions and can be used for infinitely variable change of a drive machine rotating frequency. A hydrodynamic clutch comprises the primary wheel (2) and the secondary wheel (4) with holes in a disk, a rotating housing (5), a discharge chamber (11), supports (6 and 7) of bearings of a driving rotor (1) and a driven (3) rotor, a power fluid circulation system and a member which control the clutch filling The discharge chamber casing (11) is provided with a radial hole for fitting of a rotary valve (10). The rotary valve (10) is fitted by grooves connecting the clutch work space to the surrounding space under the casing. The fluid level in the clutch is adjusted due to the radial displacement of the power fluid drainage point provided by the rotation of the rotary valve around its axis.

Shock-absorber for explosion protective elements of buildings

Single-action shock absorber comprises a housing, the elastic and damping elements, as well as an additional support rod which is rigidly fixed to the stop perpendicular to its axis, which is formed as a plate. The lower surface of the stop the damping base is attached with screws and flange sleeve located coaxially. The upper flange of the sleeve is connected to the damping base and the lower - to the clamping sleeve-type element with grooves for fixing one end of the elastic element made in the form of a conical spring which other end abuts to the cup with the bottom and the central opening, in which the rod is coaxially placed. On the outer surface of the flange sleeve the protective sleeve is mounted coaxially to the rod, made of fragile, crumbling material, such as porcelain. The cup is also made of fragile, crumbling material, such as porcelain, and is attached with screws with its sidewall to the clamping element.

Umbilical cable for continuous movement in well and method of its use

Suggested umbilical cable has channels along the whole its length filled with working media of low density as well as functional components representing components of the umbilical cable required for insulation, strength and transmission of different media - liquids, gases, electric energy and data. At that a solid body, liquid, gas or their combination may be used as working media. Characteristic property of the umbilical cable consists in that the channels filled with working media are interconnected by their ends. At that the above working media have different density and divided by elastic pistons. Besides, the umbilical cable can contain additional dummy channels permanently filled with working medium of low density. The invention also suggests the method for delivery of a subsurface device to the well survey interval by the above umbilical cable.
