Definitions

  • the present invention relates to a flexible coupling and elastic torsionimenie, and, more specifically, to a flexible coupling of easy assembly and disassembly.
  • Flexible and torsionally elastic couplings allow joining two shaft faces, accommodating radial, axial and angular misalignments that occur in each assembly.
  • a flexible and torsionally elastic coupling comprises hubs with jaws with elastic elements arranged radially between the jaws. It is these elastic elements that help to absorb misalignments, shocks and vibrations from machines whose axes are joined (ie, the driving machine or the driven machine).
  • One of the inconveniences generated by couplings of this type is related to the operations necessary for the assembly and disassembly of the coupling, for example, in case of need for maintenance of the driving or driven machines, or even in the replacement of the coupling parts.
  • to dismantle the coupling it is necessary to move at least one of the machines and lift the coupling, which requires complex and costly operations.
  • the present invention contemplates a flexible coupling of the type comprising two coupling hubs, each of the hubs being configured for mounting on a respective shaft to be coupled, in which at least one of the hubs is completely sectioned with a cross section , forming a first cube section and a second cube section.
  • At least one shear pin is disposed in an interface formed between the first and second hub sections, for torque transmission between the sections.
  • a plurality of shear pins can be used.
  • At least one of the first and second hub sections has an axial locking element.
  • the axial locking element preferably comprises a cladding element disposed at an interface between at least one of the first and second hub sections and the shaft.
  • the coupling of the present invention may comprise two fully sectioned coupling hubs with a cross section, so that each sectioned hub has a first hub section and a second hub section.
  • the second hub section can be connected to a claw part, the claw part being adapted to receive at least one flexible element.
  • the second hub section can be formed with the grip part,
  • Figure 1 - is a perspective view of the flexible coupling according to an embodiment of the present invention.
  • Figure 2 - is a perspective view of one of the hubs of the flexible coupling according to an embodiment of the present invention.
  • Figure 3 - is a schematic of the disassembly flexible coupling according to an embodiment of the present invention; and
  • Figure 4 - is a partial longitudinal section view of the flexible coupling according to an embodiment of the present invention.
  • FIG. 1 to 4 show an embodiment of the flexible coupling according to the present invention
  • the coupling comprises two hubs 1, 2, with claws 3, between which are arranged elastic elements 4 held in place by an external retaining ring 5.
  • the claws 3 can be integral with the hubs or fixed to them by means of screws 6, as shown in the figures.
  • FIG. 2 shows the coupling hub 1 without the claws.
  • Cube 1 is sectioned into two parts 1a and 1b by means of a cross section.
  • both hub 1 and hub 2 are transversely sectioned.
  • the transverse sectioning of the coupling hub in sections 1a, 1b of the hub allows the axial movement of the sections on the shaft and radial draft of section 1a (or even both sections separately) through space between the end faces of the shafts that are coupled.
  • the hub section 1b can remain on the shaft during axial movement, the assembly or disassembly operation can be performed more safely, as it is not necessary to carry out the lifting of the complete hub.
  • Figure 4 shows in more detail the construction of the flexible coupling according to the preferred embodiment of the present invention.
  • the transmission of torque between the two hub sections 1a, 1b is preferably made by shear pins 7 arranged at the axial contact interface between the hub sections.
  • At least one of the hub sections 1a, 1b has, at the interface with the shaft, an axial locking element 8.
  • This locking coating is preferably a locking coating 8.
  • the coating can be, for example, a layer of a friction material such as polymer (polyurethane), copper or aluminium.

Abstract

La présente invention concerne un accouplement flexible avec élasticité torsionnelle du type comprenant deux douilles d'accouplement (1, 2), chacune des douilles étant conçue pour être montée sur un arbre respectif à accoupler. Au moins l'une des douilles (1) est entièrement sectionnée avec une coupe transversale, de manière à former une première section de douille (1a) et une seconde section de douille (1b).
