    The invention provides a device for generating mechanical vibrations, preferably a sound-type vibrator having a cylindrical housing (1) with a coaxial stationary shaft (2), on which a sleeve-shaped working body (3) is suspended, driven by a compressed fluid to a vibrating/rolling movement. The free end of the hollow shaft is widened to a cylindrical collar (2d), whereby the inside of the housing is divided into an auxiliary (1a and a main working chamber (1c, 1d, 1e), between which communication is provided by means of a coil channel (2e) which is foreseen on the mantle surface of the collar. The superimposed radial surfaces (2f, 4b of the collar (2d) and of the cover (4) of the housing (1), which surfaces define the main working chamber in its axial direction, are tapered.

    The invention relates to devices for generating vibrations and can be used in industrial technology for influencing the components and composition of the mixtures to be made, for local mixing and pressing with their combination or in the foundry industry, chemical and other industries for producing mixtures, melts, alloys , suspensions, emulsions and other similar formulations.
    The aim of the invention is to increase efficiency by reducing rolling friction losses and eliminating the resistance and wear of elements in the area of their contact and reducing noise by ensuring quiet, without interrupting the flow of fluid through the vibration exciter.
    Figure 1 shows the vibration exciter, a longitudinal section; in Fig.2 is a section aa in Fig.K
    The vibration exciter comprises a housing 1, a shaft 2, a sleeve 3 and a locking valve 1. The housing 1 consists of rotating lower chamber 5, lower cylindrical section 6, lower expanding section 7, cylindrical section 8 and upper narrowing section 9.
    . Shaft 2 comprises a central opening 10, an upper annular part 11, a rolling surface 12 and a lower annular part 13.,
    On the outer cylindrical surface of the lower annular part 13 there is a cylindrical spiral channel 14, and the upper surface of the annular part 13 is made in the form of a tapered surface 15.
    The sleeve 3 comprises a lower tapered section 16, a cylindrical section 17, an upper tapered section 18, and a rolling surface 19. All parts of the sleeve 3 are aligned with each other.
    The locking collar 4 comprises outlet openings 20 and a tapered surface 21.
    e Using the outer cylindrical surface, the lower annular part 13 of the shaft 2 is inserted into the lower cylindrical section 6 of the housing 1. In the assembled state, the shaft 2 and the housing 5 1 form an inseparable working unit, in which the axes of all the cylindrical sections of the housing 1 are the same as the sections shaft 2 are located on the same line. The working chamber of the vibroexplosive body is closed by the collet 4, to which the upper annular part 11 of the shaft 2 fits tightly. On the other side of the collar 4 by the outer cylindrical surface tightly adjoins the core 25.
    The vibration exciter works in the following manner.
    The entry of the working fluid under pressure begins in arrow F, where the 30 exciter is connected to the source of the working fluid (not shown). Then the fluid flows along the central hole 10 of the shaft 2 into the lower chamber 5 of the housing 1, into which it enters in direction F,. From the lower chamber, the fluid flows through the cylindrical spiral channel 14 of the shaft 2 and, along this passage, accelerates from channel F to channel F, where
    extends in a certain direction at high speed into the lower expanding section 7 of housing 1,
    In addition, the fluid flow exiting from the cylindrical spiral channel 14 of shaft 2 in the form of a reinforced component, directed tangentially, expands and accelerates inside the lower expanding section 7 of housing 1, where it generates a vortex flow enhanced by an axial flow component stabilizing from inside the upper tapering section 9 of the housing 1, from which the liquid used exits through the outlet openings 20 of the lid 4.
    The vortex fluid flow into the housing I carries the sleeve 3 radially outwards until it, with its rolling surface 19, comes into contact with the rolling rolling surface 12 of shaft 2. From this moment, the sleeve 3 accelerates to a limited circulation rate, planetary motion by rolling on the surface 12 of the shaft 2. During this process, the sleeve 3 is freely positioned axially on the surface 12 of the shaft 2, which is longer than the total axial length of the sleeve 3, within the axial working gap. Since the pressure of the vortex flow on the lower tapering section of the working fluid is greater than the pressure of the vortex flow in the area of the upper tapering section 18 of the sleeve 3, the vibration exciter is maintained in a normal vertical working position, the difference in pressure of the vortex flows tends to lift the sleeve 3 and neutralize its weight, so that the sleeve 3 is suspended without impact of the adjacent elements on its front surfaces. In all other possible conditions and operating positions of the vibration exciter such as start, acceleration, is normal. operation and stopping the sleeve 3 provides minimal resistance to the movement of the front surfaces, since it is always driven either by the tapered surface 15 of the shaft 2 or by the tapered surface 21 of the cover 4 on the surface 12 of the shaft 2, and there is practically no contact between the front surfaces mi sleeve 3 and the adjacent front elements.
    During this planetary movement 5, the sleeve 3 rotates around its own axis and performs a circular movement around the axis of the shaft 2 at a distance of e. Having performed a circular movement, the sleeve 3 generates a rotational excitation force, which is transmitted using the surface of the IS. : and 3 and roll surface 12 of shaft 2,
    During operation, the outer cylindrical 15 ka section 17 of the sleeve 3 is completely separated from the cylindrical section 6 of the housing 1 by the amount of the gap z. The sleeve 3 is driven by the described vortex flow of the working liquid 20 as follows
    In the lower expanding section 7 of the housing 1, the flow is divided: one part of the flow circulates, affecting the outer surface of the sleeve 3, and another 25 part of the flow passes through the opening of the sleeve 3 and acts on the cylindrical rolling surface 19 of the sleeve 3i Both kinetic (dynamic) The components of the vortex current 30 generate a unidirectional moment of rotation (i.e., the kinetic effect of tension) of the sleeve 3, i.e., from the outer and inner sides.
    Flow S ((FIG. 2) passes through 35 sleeve 3, at the entrance, into sleeve 3 under the action of vacuum, it pulls the rolling surface of sleeve 3 and immediately thereafter brakes in the next flow passing along this rolling surface 40.
    Stream 5 passes from the outside of the sleeve 3 and acts on it in the direction of the gap z.
    The flow of BZ behind the gap separates 45 from the sleeve 3 and tightens it under the action of the vacuum that occurs. Double pushing action on the sleeve 3, t „e. The pushing action from both the external and internal side is also one of the distinguishing features of the kinetic vibration exciter.
    The constant flow of the working fluid, which is carried out with 5 minor resistances, and
    also the very low resistances to the movement of the sleeve 3 make it possible to obtain a powerful double pull force arising from the flow
    ten
    high fluids, frequencies, and large vibrator excitation forces with minimal power consumption of the fluid.
    The material of the exciter relatively well maintains high excitation forces, since the impact force is transmitted by means of full and large surfaces 12 and 19 of the shaft 2 and bushings 3, respectively, on which the contact voltages are mainly distributed.
    Formula 3 is found
