    专利说明:

    The invention relates to a hydraulic machine building, B particularly hydraulic screw machines, and can be used both as a pump and as an engine.
    A weighted hydraulic screw machine, containing a lead screw and at least one working screw with a balancing plunger mounted on its end on an axial pin on the side of the high-pressure cavity of the machine, the sub-plunger cavity of which is communicated with the 1-hight pressure cavity 1 through the channels 1.
    A disadvantage of the known hydraulic tank is that the screw assembly is inserted into the housing from the side of the high pressure cavity. This complicates the assembly process, which is time consuming.
    The purpose of the invention is to improve the assembly process technology.
    The target is achieved by the fact that in a hydraulic screw machine containing a spindle and, at least, one working screw with a balancing bolt mounted on its end on an axial pin on the side of the high-pressure cavity Maimuibi, the subplow cavity of which is connected to a half-width of 1-half pressure, screw cutting of the working screw is made along its entire length up to the balancing plunger, the length of which is less than the width of the screw groove of the cutting screw spindle.
    The drawing shows a hydraulic screw. machine (continued cut).
    The hydraulic screw machine contains the L31T located in the housing 1. all node 2, including the lead screw 3 and
    At least one working screw 4 with a balancing plunger 5 mounted on its end on an axial pin 6 on the side of the high-pressure cavity 7 of the machine, the sub-plunger cavity 8 of which is in communication with the low-pressure cavity 9 through channels 10 and an axial bore (not shown) drive screw 3. Screw threading And the working screw 4 is inserted along its entire length up to the balancing plunger 5, whose length is less than the width of the screw groove 12 for cutting the screw screw 3. The latter, with its smooth part, is installed in the packing chamber 13 and comes out of it is driven by a finger 14. The balancing plungers 5 are displaced in the cylinders 15 due to the influence of the fluid from the low pressure cavity 9 side and serve to balance the forces acting on the screw assembly 2 from the high pressure cavity 7 side.
    Making the screw thread 11 of the workpiece 4 along its entire length up to the balancing plunger 5, the length of which is reduced in relation to the width of the screw groove 12 Cutting the lead screw 3 allows for separate installation of the working screws 4 from the side of the low-pressure cavity 9 after installing the drive screw 3 cylinder 15 on the side of the high-pressure cavity 7.
    When the hydraulic screw machine acts as a pump, the inlet and outlet (not shown) of the pumping are made appropriately from the side of the cavity 9, the ino- sure pressure and the cavity 7 of the high pressure, and when it works as an engine, on the contrary “
