FGFC10 Grid Couplings

Product Details

FGFC10 Grid Couplings   Resilient Couplings give you a combination of advantages of high power rating of a gear coupling and flexibility of elastomer coupling. They are easy to install and simple to maintain. The flexible grids are quickly replaceable without disturbing the connected equipment. Resilient Couplings are available in broad range of sizes covering from 0.45 kW to 1307 kW per 100 rpm and bores up to 267mm.   Construction:   A High torque Resilient Coupling basically comprises a grid spring which connects two hubs – one on the driving and the other on the driven shafts – through axially cut grooves around the peripheries of the two hubs. The spring, which is of special design compatible to the required characteristics of the system, forms a series of resilient bridges along the grooves. The grooves are flared to allow the grid members long flexible spans under normal loads as well as better support by the sides of the grooves under over load conditions. The stiffness of the spring and thus the coupling depends on the length of each flexible span not in the contact with the grooves. Subsequently, the contact length changes with every variation in torque, resulting in change in the stiffness of the coupling at every instant during a vibration cycle. Consequently this produces a powerful detuning action resulting in continuous alteration of the torsional vibration frequency and prevention of a buildup of resonance in the system. The principle of design adopted in Resilient Coupling, makes it capable to accommodate considerable axial, parallel and angular misalignment between a driving machine and a driven machine. Simultaneously, it can absorb considerable overloads due to high torque with consequent reduction in wear and tear on plants and machinery. With the use of resilient couplings, break-down and down time in any manufacturing unit, will be minimum. Features:   1.     All metal construction having no fast wearing out components. 2.     Accurately machined. Dynamic balancing is normally not required. 3.     Torsionally flexible. Progressive torsional flexibility (due to curved profile) provides protection against shock load, impact load and vibration. 4.     Heat treated spring steel grid absorbs high impact shocks without loss of energy. 5.     Transmits full torque with dampened vibration and reduce peak loads. 6.     When over load occurs; grid fails and prevents failure of the shaft or machinery part connected to the coupling. 7.     When parallel misalignment is too severe; the related machine is protected by the virtue of shearing of Grid or Tooth. 8.     Extended life of parts of machines (Mechanical seal and Bearing etc.) 9.     Easy to install.
