    专利说明:

    The invention relates to a mouth {a) liquid supplying a pressurized fluid, in particular cooling water, to a rotating part of a machine, in particular a cutting head.
    The purpose of the invention is to increase operational reliability by reducing peak loads in pipelines to seals at high pressures.
    FIG. 1 shows the proposed device, an axial section; in fig „2-- resolve aa in fig. one; in fig. 3 shows a section BB in FIG. one,
    In the stationary part, which may be, for example, rigidly connected to a tail boom (not shown), there is a water supply system located along the axis of rotation of the rotating part, which has a water supply tube 4 screwed into the hole 3 of the stationary part. It has an axial blind hole 5 into which radial passages 6 exit, and is surrounded by a sleeve 7, which is fixed by rotation with fixed part 1 by hexagon 8. Sleeve 7 has radial passages 9 that have a common direction in the axial plane (FIG. 1) and t kzhe axial passage W, which in the same axial plane directed in the opposite direction. Radial grooves I1 and 12 are adjacent to radial passages 9 or 10, and their shape is such that the sum of the surfaces around the circumference of the annular channels
    G} 8102
    Wok 1 is approximately equal to the surface around the circumference of the annular groove 12.
    On the fixed part 1 with g-
    5 to 13 having bearings 14. The rotating part 13 of the teeth 15 enters the rotating part 16 of the machine, and the part 17 carrying the profile matched with the teeth 1b is connected to the screw 1 of the giving part 16 of the machine by means of screws 8 and rotates with it
    Rotation with part 16 of the radial holes 195 which, with its
    15 rotation about the axis 2 along the Mespe along the part of the circumference of the sleeve 7 coincides with the grooves I1.
    From the end, the device is sealed due to the fact that the inlet 20 of the tube 4 has collar grooves / -0 for accommodating the sealing rings 21, the latter inside the end end of the sleeve 7 abut on its inner surface. A tube
    The EZ 4 carries an extended head 22, which: after screwing the tube 4 into the hole 3, abuts the end face of the sleeve.
    The rotating part of the machine, 1; the wedge — for example, 5. it can be a part of the cutting head, through the seals 23 when-, ieraeT to the outer side of the sleeve 7, directly sealing the screws 18 and
    24 are held in position and under

    [1]
    1. DEVICE FOR INLET OF LIQUID UNDER PRESSURE TO A CUTTING HEAD, containing a rotating part fixed to a fixed part, on which a rotating part is mounted, a water supply tube with an axial hole in communication with the distribution cavity, and radial channels communicating with the outlets of the radial holes located on the periphery of the cutting head, characterized in that, in order to increase operational reliability by reducing peak loads in pipelines and seals at high On the other hand, it is equipped with a sleeve with radial holes attached to the fixed part, in which a water supply tube is installed, the distribution cavity is made in the form of annular grooves located around the axial hole and extending along the outer surface of the sleeve, and the radial holes are in communication with the annular grooves are located in the same axial plane with an offset along the axis and directed in opposite directions.
    [2]
    2. The device according to π. 1, characterized in that the axial hole of the water supply pipe is made blind at the end attached to the fixed part, while the radial hole of the sleeve directed to one side is located between g two radial holes of the sleeve directed to the other side.
    [3]
    3. The device according to paragraphs. 1 and 2, which is repelled by the fact that the radial channels of the water supply tube are displaced in the axial direction, are located in the same axial plane and. offset around the circumference relative to the radial holes of the sleeve.
    [4]
    4. The device according to paragraphs. 1-3, characterized in that the surface area of the annular grooves of the radial holes of the sleeve directed to one side are equal to the surface areas of the ring grooves of its radial holes directed to the other side, while the annular grooves of the sleeve are located on an arc of a central angle of 180 19 and the ends they have already been completed.
