Definitions

  • This invention relates to mechanical couplings which connect one rotatable member to another rotatable member and, more particularly, to mechanical couplings for interconnecting rotating members which may become misaligned with respect to one another.
  • one of the members may be connected to a turbine while the other of the members is connected to an electric generator or to a pump which is driven by the turbine.
  • the resulting misalignment can occur in any one or two or all three of the following manners: It can occur in “angular misalignment” wherein the axes of the two members intersect at an angle. It can also occur in “parallel offset” wherein the axes of the two members do not intersect at all. Or, it can occur in "axial movement” comprising expansion or contraction along the axis of the members. It has been a continuing problem in the art to provide a flexible coupling which is sufficiently flexible to accept all types of misalignment, while still having sufficient torque carrying capacity to transmit the desired level of torque between the two coupled members, while remaining in dynamic balance throughout its operation and while still misaligned, not producing large forces or moments on interconnected devices. The problem has become more acute where the members are driven at relatively high speeds of revolution because of the resulting increase in the centrifugal forces on the couplings, and where the operating environment imposes limitations on the physical size of the flexible coupling.
  • a pair of diaphragm type couplings is separated by a coupling shaft.
  • Each of the shafts to be interconnected by the tandem assembly is attached to a separate one of these diaphragm couplings.
  • the position of the coupling shaft floats between the interconnected shafts as the members themselves become misaligned.
  • Flexible diaphragms must be laterally stiff enough to support the coupling shaft and prevent any unstable vibratory motion, while being flexible enough to accommodate the misalignment.
  • the tandem coupling assembly has another advantage. Often, the devices from which the rotating members protrude such as turbines, pumps, and generators, have associated equipment including piping, gages, and the like, mounted near the ends of the rotating members. Thus, it is difficult to mount two such devices close together.
  • the coupling shaft of the tandem coupling assembly can be provided in various lengths to accommodate the required distances between the rotating members of two such devices. Furthermore, by providing a coupling shaft of sufficient length, bearings and seals used with the devices can be removed by disconnecting the coupling shaft and removing these through the resulting opening, rather than by dismantling the devices.
  • a flexible diaphragm member for use in a flexible coupling assembly.
  • a first rotatable member is connected to a second rotatable member through the use of a pair of diaphragm type flexible coupling members which are separated by a coupling shaft.
  • Each of the rotatable members is attached to a separate one of the flexible coupling members in this type of an assembly.
  • the torque is transmitted through a plurality of circular diaphragms.
  • Each of these diaphragms has at least one and no more than about four circumferentially extending convolutions, each of these convolutions being identical in shape and identical in position on its respective diaphragm with respect to a corresponding convolution on the other diaphragms.
  • Inner and outer clamping parts are used to secure the diaphragms in a stacked con iguration to form a pack or flexible coupling member.
  • Inner and outer separating or filler portions are provided along the inner and outer periphery of each diaphragm. The filler portions extend along both sides of each diaphragm member in the stack to support and separate them in place. The diaphragms are held in place along their filler portions by inner and outer clamping parts.
  • the clamping parts are secured together by holding means such as bolts.
  • the filler portions are generally coextensive with the clamping parts, and are as thick or thicker in cross section than the flexible convoluted nortion, thus providing integral incompressible spacing means, to prevent the diaphragms from contacting one another during the operation of the flexible coupling member. Neither the spacing means nor any other solid extends into the space between the convolutions of adjacent diaphragms. Thus, when the diaphragms are flexed in the area containing the convolutions, surface damage from contacting flexure points of the convolution is avoided.
  • the integral filler design allows the separation of the diaphragms to be minimal which stiffens the assembly laterally allowing for higher rotational speeds without damaging vibration, higher misalignment capability at a smaller diameter than the previous Anderson et al design. Since all flexure contact points are eliminated including the transition point and the diaphragms are assembled in parallel, mechanical stability will be present when properly designed with single and even multiple diaphragm failures. This produces a design of substantially smaller diameter, lighter weight and a built-in fail safe feature for reliability and life which is particularly suited for extreme conditions such as aircraft applications or critical industrial applications. By attaching the diaphragms in parallel, rather than in series, this invention can sustain diaphragm failures and maintain mechanical stability under torque, misalignment and speed.
  • a particularly advantageous size flexing area comprises one in which the ratio of the radius of the inside circumference to that of the radius of the outside circum erence of the flexing area is between about four-tenths and about six-tenths.
  • the convolution in the flexing area consist of a pair of convolutions forming an S-shape
  • substantially improved performance is obtained when the product of the thickness of a diaphragm (h) expressed in inches, and the peak-to-peak height of the two convolutions (s), measured at the center lines of the diaphragm material and also expressed in inches, is greater than about 0.0015 and less than about 0.0035.
  • Each diaphragm member comprises a single member having an annular flexible convoluted portion, an integral annular inner clamping or filler portion defining about its inner periphery, a hole, an integral annular outer clamping or filler portion defined about its outer periphery.
  • the inner and outer filler portions being uniform thickness and being thicker in cross section than the flexible convoluted portion.
  • An annular inner transition portion extends between the flexible convoluted portion and the annular inner filler portion provides a smooth transition from the thicker inner filler portion to the flexible convoluted portion.
  • An outer transition portion is provided between the flexible convoluted portion and the outer filler portion and provides a smooth transition from the outer filler portion to the flexible convoluted portion.
  • the inner and outer filler portions are defined by two flat parallel sides which permit the diaphragm members to be stacked with the outer filler portions resting on one another and the inner filler portions resting on one another and the flexible convoluted portions being disposed in spaced nested relation to one another so that in operation, the flexible convoluted portions are spaced from one another sufficiently that they are prevented from chafing one another.
  • the flexible convoluted portions are uniform in thickness throughout their length.
  • An independent means of clamping the diaphragm pack together is provided in the coupling design so that the diaphragm pack acts as a cohesive member.

Abstract

Un couplage (10) du type à diaphragme flexible transmet un couple par l'intermédiaire d'une pluralité de diaphragmes flexibles (22). Chacun de ces diaphragmes possède une région de flexion qui comprend au moins une circonvolution circonférentielle (24). Les régions flexibles sont maintenues espacées par des zones de remplissage intégrées internes et externes (26, 28) dont la section est plus épaisse que les régions flexibles et sont empilées de sorte que les zones entre les régions flexibles soient exemptes de tout solide de manière à éviter le contact entre les points de flexion et les zones de transition (30, 32), évitant ainsi tout dommage aux surfaces. Cette invention rend possible des conceptions de couplage qui acceptent des défauts d'alignement plus importants, des diamètres et des encombrements plus petits ainsi que des masses de couplage plus petites à des vitesses de rotation plus grandes qu'antérieurement. De même, étant donné que le contact entre tout point de pression est éliminé et que les diaphragmes travaillent en parallèle, la longévité du couple est considérablement améliorée. Dans l'éventualité peu probable d'une défaillance d'un diaphragme la stabilité mécanique et le fonctionnement du couplage sont maintenus même à des vitesses de fonctionnement élevées.
