Description

1. 2485662

  Set of adaptable elements for mechanical coupling

  from an engine to a hydraulic pump.

  The present invention relates to a set of elements to be assembled or adaptable for the mechanical coupling of an actuating motor to a hydraulic pump. A coupling "lantern" has been used for a long time for coupling an electric actuating motor and a hydraulic pump, a flange of which is connected to a corresponding flange of the electric motor and the other end of which is connected to a corresponding flange of the electric motor.

  side is connected to the flange of the hydraulic pump, the shaft

  said electric motor and the shaft of said hydraulic pump being coupled by means of appropriate seals within the

Lantern.

  It is also known that the flanges of electric motors

  are standardized and, as such, they can be easily

  coupled with the corresponding mating flange of

  the lantern, the latter being adapted to given powers.

  This does not apply to hydraulic pumps to be connected or

  mate, because we can find on the market pumps for-

  views of square, rectangular or oval coupling flanges. As a result, in practice, it is necessary to provide a lantern for each pump, provided with a particular flange

  for coupling with the flange of the hydraulic pump.

  Therefore, until now, it was essential to have in store, for each type of pump, a corresponding coupling lantern which was generally a single piece made by molding aluminum and similar materials. It was therefore essential to have in store a large number of lanterns to allow the coupling of pumps

  hydraulics of different construction with electric motors

different powers.

  These lanterns, all different, could not be superimposed or stacked in a small space because of their particular shape, so that their storage or transportation was very expensive and frequently there could be found in store the lanterns of coupling with flanges

2 2485662

  allowing their coupling to a given pump.

  The object of the present invention is to eliminate the

  mentioned above. It aims at a lantern of

  a combination of individual elements that can be accom-

  between them and with the flanges of hydraulic pumps the

  more different, as well as with the flanges of the drive motors.

  in order to allow the coupling of most

  known hydraulic pumps, by means of a very large number of

  coupling elements, with actuating motors

  corresponding, for example, with powers

be 0.12 Kw and about 164 Kw.

  Another object of the present invention is to standardize

  maximize the composable coupling elements that

  said lantern, so as to allow at the same time their

  stacking and storage in a very small space.

  The aims mentioned above are obtained, according to the present invention, by a set of means or elements

  adaptable for the mechanical coupling of an engine

  and a hydraulic pump, characterized in that said assembly comprises a first coupling element adapted to

  connected to the flange of the actuating motor, a second element

  intermediary coupling capable of being connected to the

  free of said first coupling element, and a third coupling element adapted to be connected to the free end of said intermediate coupling element, the free end

  said third coupling element being adapted to be

  connected to the flange of the hydraulic pump.

  The first coupling element has advantageous

  frustoconical shape, so as to allow stacking

  said coupling elements one above the other.

  The second coupling element advantageously has

  an annular shape and is equipped with coupling

  dimensioned to allow coupling with the free end of the frusto-conical element or with the corresponding end of the third coupling element,

  which can be connected to the hydraulic pump.

  In a particularly advantageous manner, the second coupling element can have a cylindrical shape,

3 2485662

  in order to connect the free end of the coupling element

  cone with the third coupling element,

  attached to the pump and having a diameter equal to that of the end

  free of the frustoconical coupling element.

  The second coupling element may also have

  a frustoconical shape, so as to connect the element

  coupling element associated with the actuating motor with a connection element associated with the pump and provided with a flange

having a smaller diameter.

  Returning from 1800 the intermediate coupling element

  truncated cone shape, it is possible to connect the

  truncated cone and having a smaller diameter face to a coupling element connected to the pump and having a flange

of larger diameter.

  The invention will be better understood on reading the

  detailed description that will follow and review the drawings

  annexed which represent, by way of non-limiting example, a

  embodiment of the invention.

  individual coupling elements, arranged between an actuating motor and a hydraulic pump;

  as an intermediate element between the coupling element

  associated with the motor and the coupling element associated with the pump, a cylindrical ring;

  For example, a ring extending from a smaller diameter to a larger diameter is a top view showing the face of the coupling member associated with a hydraulic pump, along the line VV of FIG. ; and

  FIG. 6 shows frustoconical coupling elements associated with the actuating motor and stacked

on each other.

  FIG. 1 shows an electric motor which is provided with a standard coupling flange 2, to which can be coupled or connected, by means of screws not shown,

  the flange 3 of a first coupling element 4.

  The coupling element 4 has a frustoconical shape and it is provided, on its front part, with a re-entrant seat 5, able to receive the tapered portion 6a (6b) of a second element

  intermediate coupling 6, the latter being furthermore

  seen from a tapered part 6b on its opposite side.

  The second intermediate element 6 can have the shape

  a cylindrical ring, or the shape of a frustoconical ring.

  In the latter case, the tapered parts 6a and 6b have a di-

  different meter. By means of screws (not shown), the element

  6 can be rigidly connected to the coupling element

  4. The tapered anterior part 6a of the

  intermediate 6 can be introduced into a corresponding re-entrant portion 7 of a third coupling element

  8 whose face 9, turned towards the flange of a pump hy-

  hydraulics 10, is dimensioned so as to allow its accou-

  10 with the flange 11 of the hydraulic pump 10. This coupling is advantageously made by means of screws, no

represented.

  Since the unique structure whose shape changes sensi-

  for given power values is the flange 11, which may have a plurality of shapes, generally different according to the manufacturers, it is sufficient to adapt the face 9 of the third coupling element 8 to different requirements, while the coupling element 4 can be

  used for all electric motors 1 having a

  this data, because almost all electric motors

  are equipped with a standardized coupling flange 2.

  Thanks to the presence of the international coupling element

  6, formed for example of a simple rotated ring, it can establish the coupling between the coupling element 8 and the coupling element 4, or when the faces 5 and 7 have

2485662

  In employing an intermediate coupling ring 6 of conical shape, a coupling element 4 having a larger face 5 can be coupled with a coupling element 8 having a smaller face 7. By reversing the intermediate coupling element 6 from 1800, a coupling element 4 having a smaller diameter face 5 can be coupled with a coupling element 8 having a face 7.

  of larger diameter. In this way it is possible to increase

  Subsequently specify the number of possible mating combinations, without the need to use other elements

  as shown clearly in FIGS. 2 to 4.

  In FIG. 2, a coupling element has been coupled

  4 with the interposition of an intermediate coupling element

  6 cylindrical, the diameter of the face 5 of the element

  coupling 4- being equal to the diameter of the face 7 of the ele-

coupling 8.

  FIG. 3 shows how to couple a coupling element 4 by means of a frustoconical intermediate coupling element 6, so as to reduce the face 5 of the coupling element 4 to the face 7 smaller diameter

of the coupling element 8.

  Naturally it is also possible, as shown in Figure 4, to use the intermediate frustoconical coupling member 8 in the opposite direction in order to increase the diameter of the smaller face 5 of the coupling element 4 to the

  face 7 of larger diameter of the intermediate element 8.

  FIG. 5 shows the third element

  coupling with its face 9, seen from above.

  From Figure 5 it appears that by giving the face 9 a suitable shape, it is possible to obtain a coupling with different flanges 11 of hydraulic pumps 10. Thus,

  for example, on the face 9 of the intermediate coupling element

  8, it is possible to mount a pump provided with an oval flange 11 ', or a rectangular flange 11 ", or a square flange

  11 "', as shown in FIG.

broken.

  FIG. 6 shows finally that the coupling element

  4, the flange 3 of which can be connected to the flange 2 of the

6 2485662

  actuating motor, can be stored in a very

  reduced, by stacking the coupling elements 4 one another

  above each other. This is possible thanks to the truncated form

  that particular of the coupling element 4.

  Even though the construction of the coupling lantern into several individual elements may seem more expensive, the many advantages gained with these adaptable lanterns

  according to the present invention make it possible to

  savings. Indeed, it becomes unnecessary to store lanterns of particular shape, for adaptation to a particular type of pump, and with a very small number of elements

  adaptable, most connections can be made

  used for the most different types of pumps and

  with the most varied electric motors.

  Of course, the invention is not limited to the embodiment of the example described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the intended applications and without departing

for this purpose of the scope of the invention.
