    1. Barrel mechanism comprising, inside a casing (1), a drive member (4) mounted pivotally on at least one fixed bearing (31, 32) defining an axis (10) about which the drive member (4) is driven rotationally, a barrel (5) rotationally fixed and mounted pivotally on the drive member (4) about an axis (50) inclined relative to the axis of rotation (10) and convergent with the latter, a first axial thrust bearing (52) interposed between the barrel (5) and an oblique plate (40) disposed on the drive member (4) perpendicularly to the axis (50) of the barrel, and a second axial thrust bearing (44) interposed between a straight plate (45) disposed on the drive member (4) perpendicularly to the axis of rotation (10) and a fixed plate (33) which, through the medium of the two axial thrust bearings (44, 52), takes up the forces parallel to the axis of rotation (10) which are applied to the barrel (5), characterised by the fact that the fixed plate (33) is disposed at one end of a central column forming a spindle (3) defining the pivot axis of the drive member (4), while at the other end of the said central column is supported a means (6) for the elastic clamping of the drive member (4) against the fixed plate (33), the cassing (1) being provided with detechable means for fastening the spindle (3), the latter forming with the drive member (4) and the barrel (5) a compact assembly adapted to be installed in and removed from the interior of the casing (1) as a unit.

    The invention relates to pumping, in particular to axial-or-ash pumps.
    The purpose of the invention is to provide the possibility of block-mounting the mech-ism into the cavity of the body and its demolishing.
    FIG. 1 shows the mechanism of the transposer, a longitudinal section; on ig. 2 is the same as the embodiment. The mechanism for converting the drive of an axial-piston pump to a fixed cylinder block holds the housing 1 with walls 2 and 3 and the connecting wall between these walls and the clamping wall 2 and 3 with a pre-tensioned thrust 4.
    In the cavity of the housing 1 there is a tubular support 5 installed on it with the possibility of rotation on two bearing assemblies 6 and 7, a hollow driven shaft having an end bearing surface 9 located perpendicular to its rotation axis 10, a cylindrical landing surface 11, axis 12 of which is made obliquely to axis 10 of rotation of the driven shaft 8 and intersects it at point 13, and inclined bearing surface 14 perpendicular to p-30 but to axis 12 of the fitting cylindrical surface 11. The mechanism also includes a fixed from rotation Relative to the housing 1, a drum 5 mounted with a bearing 35 16 on the cylindrical seating surface 11 of the driven shaft 8 with the possibility of relative rotation.
    The mechanism has two axial bearing supports 17 and 18 mounted 40 to receive forces from the pump pistons 19 applied to the drum 15 in a direction parallel to the axis 0 of rotation of the driven shaft 8. The support 17 is installed between the end surface of the drum 15 and the inclined bearing the surface 14 of the hollow driven shaft 8, and the support 18 is installed between the end support surface 9, the driven shaft 8 and the support end surface 50 of the tubular support 5. Last at the end facing the pump pistons 19, is provided with a threaded surface portion 2 ustanozlvnnoy thereon clamping nut 22 and the elastic element-55 ment 23 as a set of Belleville springs for urging poloho On the driven shaft 8 to the end surface of the support

    20, mounted between the clamping nut 22 and the first bearing assembly 6 (FIG. 1).
    The bearings 24 of the first bearing assembly of the hollow driven shaft 8 may have tapered rollers, the axes of which are inclined relative to the axis 10 of rotation of the driven shaft 8, and the elastic element for pressing the bearings 24 may be made in the form of a sleeve 25 installed with the possibility of contact with the inner bearing ring 24 and clamping nut 22 (figure 2),
    When used in bearings bearing 17 and 18 bearings with taper rollers (Fig. 2), bearing 7 can be excluded, the functions of which centering the driven shaft 8 are provided by the bearing with tapered rollers whose axes are angled to the axis of rotation 10 of the driven shaft 8,
    The hollow driven va-G 8 is provided with a toothed crown 26, which engages with the toothed crown of the drive shaft 27.
    The pistons 19 of the pump are connected to the drum 15 by means of connecting rods 28 having ball joints 29. The bearing 16 is held against axial movement by means of a nut 30, a spring blue washer 31, a circular ring 32 and an abutment 33 (Fig. 1). In the case of application to the onic bearing 16 (Fig. 2), it is held against axial movement by means of a nut 30.
    The end of the tubular support 5 is placed 3 bore 34, made in the wall 3 of the housing i. A hectare 4 is installed inside the tubular support 3 and secured with a nut 35.
    The mechanism is mounted as follows.
    Outside the housing 1, the hollow driven shaft 8 and the drum 15 are mounted on the tubular axis 5 on the respective bearings, after which all the required adjustments of the mechanism are carried out. At the end of the adjustment, the mechanism is inserted into the cavity of the housing 1, and the end of the tubular support 5 is inserted into the bore 34 of the wall 3 of the housing.
    After installation of the mechanism between the walls 2 and 3 of the housing 1 inside the tubular support 5, a ha 4 is installed, which, after a pre-ioro tension, is fixed by a nut
    35, with the result that the mechanism is clamped between the walls 2 and 3 of the housing 1, after which it is possible to install the connecting rod heads 28 into the drum 15.
    Thus, the assembly of the pump as a whole is considerably simplified, since it is possible to make all the required adjustments of the conversion mechanism outside the body cavity.
    Removing the mechanism from the cavity of the housing 1 is also technically simple, since after disconnecting the heads of the connecting rod 28 from the drum, it is sufficient to remove the hook 4, after which the mechanism is freely removed from the cavity of the housing for servicing.
     Thus, it is possible to block-mount the mechanism into the body cavity and dismantle it.
