    • 专利摘要:
    The pump comprises a cylinder drum (20 converted to a shaft (1) and equipped with pistons (4) fitted in cylinders (3). The piston heads press against the oscillating plate (7) in such a way that the forces of the pistons do not produce only a useful torque on the cylinder drum (2), but also a radial transverse force (PK Res), the application point of which (10) is located in the axis of the shaft (1). The plane (13) of a bearing (12) supporting the drum (2) on the housing (8) intersects the axis (9) of the drum (1) at a certain distance from application point (10) of the transverse drum force (PKRes) on the side of the drum (2). The straight line (14) resulting from all the bearing forces acting perpendicularly on the guide path (15) of the bearing (12) forms a sharp angle (26) with the drum axis (9) and intersects the latter practically at the point of application (10) of the transverse force (PK Res), so that the bearing pressure of the drum takes effect in the region of this application point (10) and unwanted overturning torques acting on the drum are avoided.

    专利说明:

    The invention relates to mechanical engineering, where axial-piston hydraulic machines with an inclined disk are used, for example, in road transport, railway, air and water transport.
    The purpose of the invention is to increase reliability by reducing the overturning moment.
    Fig. 1 shows an axial piston hydraulic machine with a conical guide made on the housing; Fig. 2 shows an axial piston hydraulic machine with a trunnion and a conical guide made on the cylinder block; Fig. 3 is an axial piston hydraulic machine with a trunnion passing through the central bore of the cylinder block.
    The axial-piston hydraulic machine comprises a cylinder block 3 with pistons 4 mounted in the housing 1 on the support 2, the heads 5 of which are placed in the shoes 6 supported on the inclined washer 7, the drive shaft 8.
    Right 9, coinciding with the direction of the resultant force. perpendicular to the support 2, forms an acute angle 11 with the longitudinal axis 10 of the cylinder block 3 and intersects it in the zone

    the intersection point 12 is a longitudinal axis 10 of the plane 13 passing through the centers 14 of the heads 5 of the pistons 4. The intersection point 12 is offset relative to the plane 15 in which the support 2 of the cylinder block 3 is placed, towards the inclined washer 7. The pump is provided with a conical guide 16 can be performed on the housing 1, and a support 2 is installed between it and the cylinder block 3. In the second pump variant, the conic guide 16 can be performed on the cylinder block 3. In this embodiment, the pump is provided with a trunnion 17, which is fixedly mounted on the housing 1 Torons the swash plate 7, passes therethrough, is hollow and coaxially mounted about the shaft. A support 2 is installed between the conical guide 16 and the trunnion 17.
    In the third embodiment of the pump, the trunnion 18 passes through the central bore of the cylinder block 3, and the support 2 is installed respectively between the conical load 16 of the cylinder 3 and the trunnion 18. Both the bearing 19 and the tapered roller bearing 20 can be used as support 2. The inclined washer 7 is movably mounted in the housing 1. The cylinder block 3 is in contact with the distribution disk 21, which distributes the flow and removal of the working medium. The drive shaft 8 is installed in bearings 22.
    Through the inclination of the inclined washer 7, the forces developed by the pistons 4 arising under the pressure of the working medium, each piston 4 is directed vertically to the sliding plane of the inclined washer 7, which maintains balance with its axial component force developed by the piston force and thereby creating a transverse force of the piston, which, summing up the action of all the pistons 4 together with the torque on the cylinder block 3, creates a radially acting transverse force of the block with a point 12 of application of force, aschey on the axis 10 the cylinder 3.
    Axial-piston hydraulic machine in pump mode works as follows.
    When the drive shaft 8 rotates, the cylinder block 3 performs a rotational motion, and the pistons 4 - translational, thereby pumping the working medium.
