    Unitary cage assembly (52) annularly positioning a plurality of rollers (36) in a pair of roller bearings (32 and 34) supporting a cradle swashplate (24). By utilizing the unitary cage assembly, a parallel relationship between the rollers is assured and, furthermore, only a single locating mechanism (60) for the unitary cage assembly is required.

    from the washer 8. In the washer 8 there is a central hole 9 under the shaft 2. On the side 10, the pro-proppant surface 7, a pair of arcuate bearing surfaces 11, 12 are formed, each located on either side of the hole 9. Between the surfaces 11,12 and arcuate The body section 1 is provided with support means 14 comprising a pair of sets of roller bearings 15, 16 spaced from each other. The tool 14 is provided with a separator (C) for bearings 15, 16, made in the form of parallel elements with slots for bearing elements connected
    The invention relates to hydraulic engineering, in particular to adjustable axial-piston hydraulic actuators with an oscillating washer.
    The aim of the invention is to simplify the construction and installation by engaging, fixing and precisely positioning the bearing elements between
    the supporting surfaces of the swashplate and the arcuate surface of the housing, as well as limiting the movement of the separator along the arcuate supporting surfaces of the swashplate when it is moved or tilted.
    FIG. 1 shows a hydraulic machine, a cross-section} in FIG. 2 shows a tilting washer with support means and mounting device J in FIG. 3 is one of the embodiments of the support means separator.
    The hydraulic machine comprises a housing 1 within which a cylinder block 3 is mounted on a shaft 2 rotatably around axis 4. In cylinders 5 of block 3 of cylinders there are pistons 6 in contact with cam surface 7 of rocking washer 8. In washer 8 there is a central hole 9 under shaft 2. On the side 10 opposite the cam surface 7, there is a pair of arcuate bearing surfaces 11 and 12 located on either side of the central opening 9. Between the pair 11 and 12 and the arcuate section 13 of the housing 1 there is a support means 14, containing A pair of roller bearing sets 15 and 16, a pair of transverse elements of the central shaft bore 2, located coaxially with the bore 9. moving it. The device 32 is mounted on the housing 1 on the side of the side lug 33. The link 36 is connected to the pins 34.35. The means of receiving the scenes 36 is made on C and comes into contact with the scenes 36. The device 32 limits the movement of C on the surfaces 11,12. 8 hp f-ly, 3 ill.

    separated from each other, and the separator 17 with slots 18 for bearings 15 and 16.
    The separator 17 is made in the form of parallel elements 19 and 20, connected by a pair of transverse elements 21 and 22 with the formation of a central bore 23 for the shaft 2, which is located coaxially with the opening 9 of the swashplate 8. The separator 17 can be made as a single piece of one material. The transverse elements 20 and 21 can be made in the form of separate elements 24 and 25, 26 and 27, the ends of which are provided with transversely arranged legs 28 and 29, 30 and 31, which are in engagement with each other to form a pair of transverse elements 21 and 22 .
    Nylon can be used as a material for the separator 17.
    The separator 17 is provided with a mounting device 32, which restricts its movement along the arcuate bearing surfaces 11 and 12 of the rocking washer 8 and is located on the side of the side plate 33 fixed to the housing 1. The mounting device 32 has two pins 34 and 35, and the pin 34 is mounted on the housing 1, and the pin 35 is on the swinging washer 8. With the pins 34 and 35, the ball is nernally connected to the slide 36, which comes into contact with the means 37 for receiving the slide 36, made in the form of a groove on the protruding part 38 of the separator
    17. The swivel 39 of the scenes 36 contains a means of dead stroke, designed in the form of an elongated slot 40, which engages with a pin 35 mounted on the rocking washer 8. The curved wire can be used as the scenes.
    Hydraulic machine in pump mode works as follows.
    When the shaft 2 rotates, the cylinder block 3 rotates around the axis 4 at the same time as the piston 6, in contact with the rocking washer 8, the working fluid is sucked in and out. During operation, the performance of the hydraulic machine can be adjusted by changing the angle of inclination of the swinging washer 8 or by turning it to a specific gene angle. These movements are possible due to the supporting means 14J, the arc-shaped movement of which is limited by the installation device 32. In order to have a ratio of 2: 1 between the arc-shaped movement of the swing washer 8 and the arc-shaped movement of the separator 17, the axis of the pin 35 and Rütup 38 must be doubled compared to the distance between the shtkfta axle 34
    and protrusion 38.
