Definitions
- the subject of the invention is an oblique plate mechanism which can be used in particular for controlling a pump.
- Such mechanisms which have been known for a long time, include, inside a casing, a control part rotatably mounted about a longitudinal axis and on which is formed a journal axis of an oblique plate inclined relative to the 'longitudinal axis and bearing on the control part by means of an axial stop.
- the pump comprises a plurality of pistons distributed around the longitudinal axis and sliding parallel to the latter in cylindrical bodies formed in a cylinder head fixed on one of the bases of the casing in which the mechanism is placed. Each piston is individually connected to the oblique plate, for example by means of an articulated rod and the oblique plate is locked in rotation.
- the oblique plate is animated with an oscillating movement around the point where its axis of journalling intersects the longitudinal axis of rotation and which therefore constitutes a center of oscillation. Since the oblique plate is locked in rotation, this oscillation movement determines an alternating longitudinal movement of the pistons by means of articulated rods. Longitudinal forces are therefore developed by the pistons between the cylinder head fixed on the rear bottom of the casing and the oblique plate which is supported on the control part, the latter taking support in turn, by means of a stop. axial, on the front bottom of the casing. Thus, all of the forces must be supported by the casing, more particularly by the two bottoms thereof and the side wall which connects them together. When the pump is of high power, the casing must withstand significant efforts and we are led to very heavy and bulky achievements.
- the subject of the invention is improvements to this arrangement which allow the casing to resist alternating forces even in the case of a high power pump while keeping a relatively light structure.
- the two casing bottoms are connected on their periphery by a plurality of additional lateral tie rods parallel to the central axis, bearing on the two casing bottoms and subjected to a prestressing tension capable of compensating for the forces developed by the pistons, in cooperation with the central tie rod, each piston corresponding either to a single lateral tie rod, centered in the radial plane passing through the central axis and the sliding axis of the piston, or to a pair of lateral tie rods placed symmetrically on either side of the corresponding radial plane.
- the rotary control part bears on the front bottom of the casing along a circumference centered on the longitudinal axis and passing through the axes of the pistons, by means of a circular rib formed on a fixed transverse plate placed at the front end of the central spacer column.
- FIG. 1 there is shown the assembly of the pump 1 and the control mechanism placed inside a casing 2 and consisting of a control part 3 rotatably mounted around an axis 30 on a column hollow 4 and on which an oblique plate 5 is mounted journalling about an axis 50 inclined at an angle (i) relative to the longitudinal axis 30 and cutting the latter into a center of oscillation 0.
- the pump 1 is constituted by a plurality of pistons 6 slidingly mounted each along an axis 60 parallel to the longitudinal axis 30, at inside cylindrical bodies 61 integral with the cylinder head 11 of the pump.
- each piston 6 is integral with a slide 62 guided along the axis 60 inside a cylindrical body 63.
- Each slide 62 is connected to the oblique plate 5 by a connecting rod 64 provided with its two ends of two ball joints 65 and 66 for connection, respectively, with the oblique plate 5 and with the slide 62.
- the oblique plate. 5 is mounted pivoting around the axis 50 on a bearing 51 mounted on an inclined bearing 31 provided on the control part 3.
- the latter is also provided with an inclined bearing surface 32 placed in a plane perpendicular to the axis 50 and on which the oblique plate 5 is supported by means of an axial stop 52.
- control part 3 is also supported by means of an axial stop 33 on a transverse plate 41 formed at the end of the column 4 opposite the pump 1 and perpendicular to the axis 30, the column 4 also carrying a bearing 34 for axially guiding the control part 3.
- the centers of the ball joints 65 connecting the connecting rod 64 with the plate 5 are placed at the meeting points of the axes 60 of sliding of the pistons 6 with a plane perpendicular to the inclined axis 50 and passing through the center of oscillation 0, for the two extreme angular positions of the oblique plate for which the axis 50 is in the radial plane passing through the longitudinal axis 30 and the axis 60 of the corresponding piston.
- the centers of the ball joints 66 for connection with the slides 62 are also placed on the sliding axes 60.
- the thrust of the pistons 6 is therefore collected by the oblique plate 5 and transmitted to the control part 3 then to the fixed transverse plate 41 respectively by the axial stops 52 and 33.
- a tie rod 8 which passes to inside the central tubular column 4 and is provided at its two ends with support heads 81 and 82, respectively on the rear bottom 21 and on the front bottom 22.
- the latter has the shape of a box in the center which is placed an axial column 23 which is in the extension of the spacer column 4 and on which the latter bears on the side of the pump.
- the casing 2 is further provided with a plurality of lateral tie rods 80, placed on its periphery, to take up the forces developed by the pistons each in cooperation with the central tie rod and which are distributed at this effect symmetrically with respect to the radial planes passing through the longitudinal axis 30 and through the axes 60 of the pistons 6.
- Each piston 6 can therefore correspond either to a single lateral tie rod 83 placed in the corresponding radial plane P, or to two lateral tie rods 85 placed symmetrically on either side of the corresponding radial plane.
- the casing 2 comprises two upper lateral tie rods 83 centered in the radial planes corresponding to two pistons 6a and 6b while the forces developed by the third piston 6c are taken up, in cooperation with the central tie rod 8, by two other lower tie rods 85 placed symmetrically on either side of the corresponding radial plane P 1 .
- each tie rod 80 is provided at its ends with heads 87 bearing on the external faces of the two bottoms 21 22 of the casing and pass through a spacer column 24 constituting the casing and interposed between the two bottoms so as to prevent them from coming together under the action of the prestressing tension when the thrust of the corresponding piston does not not exercise in reverse.
- the prestressing tensions and consequently the cross sections of the tie rods will be determined as a function of the forces developed by the pistons and of the distances from the axes 60 of the latter relative to the lateral tie rods 80 and to the central tie rod 8.
- the entire casing 2 is in mechanically welded construction and, thanks to the solutions adopted, can be relatively light.
- Each bottom has the shape of a box made up of transverse plates connected by spacers. These are constituted by the central column 23 and by the lateral columns 24 in the case of the rear bottom 21 which constitutes the fixed base of the installation on which the pump 1 is fixed on one side and the control mechanism 3, 4, 5.
- the front bottom 22 is formed of a box consisting of two side plates connected to each other by spacer walls 25 placed around. orifices 26 for passage of the tie rods 80, in the extension of the walls of the columns 24 of the corresponding tie rod.
- the cylinder head 1 is advantageously provided with a fixing plate 12 which is applied to the external face 27 of the rear bottom 21 and on which the heads of the central tie rod 8 and of the lateral tie rods 80 rest, which pass through holes in the plate 12.
- This arrangement therefore makes it possible to easily dismantle, by loosening the tie rods, the assembly of the pump 1.
- the hydraulic body casing assembly therefore forms a pre-stressed rigid block, easily removable, and well resistant to strong internal thrusts of the pistons.
- the axial support of the control mechanism on the front bottom 22 takes place along a circumference centered on the longitudinal axis 30 and of radius R equal to the distance between the axis 30 and axes 60 of the pistons.
- the transverse plate 41 is provided, on the bottom side 22, with a circular support rib 44 having an average radius equal to R.
- a disc 25 forming a shim is thick interposed between the support rib 44 and the internal face of the front bottom 22 and the central column 4 rests on the end of the axial column 23 of the front bottom 21 by means of an adjustable stop which can be constituted for example by a nut 45 screwed on a thread formed at the end of the column 4 facing the pump 1.
- the invention is not limited to the details of the embodiment which has just been described by way of simple example and which could be modified by using equivalent means.
- This is the case in particular of the physical production of the mechanism, the pump and the casing.
- it could consist of a simple plate provided on its external face with reinforcing ribs passing through the longitudinal axis and through the axes of the lateral tie rods and of the corresponding pistons.
