    The invention relates to a pump construction, in particular to axial-piston machines with an inclined washer.
    The purpose of the invention is to strengthen the structure without significantly increasing its size and weight.
    FIG. 1 shows a mechanism with an inclined washer for an axial-piston pump, a longitudinal section, which is made stepwise, passing through the axis of the piston, the central one and one of the additional lateral drawbars; in fig-. 2 is a section A-A in FIG. one .
    An inclined washer mechanism for an axial piston pump comprises a crankcase 1 with a front 2 and a rear 3 bottoms driven shaft 4 mounted rotatably on a thrust bearing 5 of a hollow support 6 facing the front flange 2 to cooperate with it through a sealing gasket in the form of a disk 7 ring on juice 8, an inclined washer 9, zab.11okirov; from rotation, mounted on the driven shaft4 with the possibility of swinging around the center 10 of the swinging, located at the intersection of the longitudinal 11 and inclined 12 axes, and equipped with an axial stop in the form of a bearing 13, a plurality of pistons 14 evenly spaced around the axial axis 1 1 with reciprocating movement parallel to the longitudinal axis 11 in cylindrical housings 15, filled 29628
    The number of columns 25 is equal to the number of BT 22. The floor of the support 6 is made split in two parts, and each crankcase is made in the form of a rigid welded caisson, formed of parallel plates interconnected by spacer racks 28. The forces developed by P 14 are perceived 21 and WT 22. The welded design of the crankcase 1, together with the rods 21 and 22, and the spacer elements in the form of a support 6 and columns 25, increase the rigidity of the crankcase and make the whole mechanism more durable. 7 hp f-ly, 2 ill.

    heads 16, and interacting with an inclined washer 9 using crosshead 17 and connecting rods 18, with spherical heads that form in the interaction zone with an inclined washer 9 and crosshead 17 17 ball joints 19 and 20, respectively.
    The front 2 and rear 3 bottoms are interconnected by means of a prestressed central pull 21 passing through both bottoms along the longitudinal axis 11 and installed with the ability to interact with the outer ends of these bottoms to perceive at least part of the efforts developed by the piston 14, as well as a plurality of peripheral bottoms 2 and 3, additional side rigs g 22, mounted parallel to the central pulley 21 with the possibility of interaction with both bottoms 2 and 3 and subjected to preliminary stj for the reception together with the central thrust 21 of the forces developed by the pistons 14.
    The number of side t 22 gs may be equal to the number of pistons 14, each side of the ha 22 being located in a radial plane 23 passing through the longitudinal axis 11 and the axis of the corresponding piston 14, or twice the number of pistons 14. In this case each pair of side t r 22e5 on symmetrically on both sides radial0

    passing through and the axis of the corresponding piston 14 (Fig. 2).
    The mechanism is equipped with hollow spacers 25, ycTaHOBj-enamel with the ability to interact with the internal surfaces of the front 2 and rear 3 bottoms of the crankcase 1 for receiving the forces of prestressing additional lateral ratios g 22, the number of columns 25 being equal to the number of additional lateral t g 22.
    The floor bearing 6 is made of split parts in two parts, one of which is provided with a threaded surface section and an adjusting nut 26 for pressing the end of the other part 27 of the hollow support 6 to the rear bottom 3 of the crankcase 1.
    In addition, each bottom of the crankcase 1 is made in the form of a rigid welded caisson, formed by parallel plates interconnected by spacers 28, mounted around openings for the passage of a bent head with working cylinders and
    22 in the continuation of the walls of the spacers 25, the front bottom 2 of the crankcase 1 is provided with stiffening ribs passing through the longitudinal axis 11 and the axes of the side grids 22.
    The prestressing of the center pull of the pull 21 is carried out by nuts 29 mounted on the ends of the pull 21, and the preload of the additional side draws 22 by the nuts 30.
    The driven shaft 4 of the mechanism is provided with a gear crown 31 engaging with the crown of the gear wheel 32 mounted on the drive shaft 33. A bearing 34 is mounted between the hollow support 6 and the driven 4.
    The mechanism works as follows.
    When the drive shaft Z 3 rotates, the driven shaft 4 is rotated, while the oblique washer 9, blocked from rotation, oscillates about the center 10 of the swing, located at the intersection of the longitudinal 11 and the inclined 12 axes. The rocking motion of the inclined washer 9 by the rods 18 is transmitted to the crossheads 17 and the associated pistons m 14, which at the same time reciprocate in cylindrical bodies 15 of the head 16, which leads to a periodic increase and decrease

    chambers of the pump and the implementation of its tact of suction and injection. The forces developed by the pistons 14 are perceived by the prestressed center 21 and the additional lateral 22 tons.
    Thus, the welded design of the crankcase 1 together with the central 21 and lateral 22 tons gm and spacer elements in the form of a composite hollow support 6 and spacer columns 25 can significantly increase the rigidity of the crankcase and make the whole mechanism more durable overall dimensions and weight.
