Grid Couplings Overview: 
 Grid Couplings use is divided into one group or several groups of serpentine springs, embedded in between the teeth on the flange of the coupling halves to the two halves of the coupling connection in order to prevent the snake spring thrown and to avoid the serpentine spring tooth contact at dry friction, the centrifugal force required a closed shell covering the inside Note lubricating oil or grease. Grid Couplings are divided into constant stiffness and variable stiffness two kinds mainly depends on the spring contact with the teeth of the following two forms: toothed linear: in the normal load, the distance between the snake-like spring and the tooth contact points deformation changes in the amount of change does not vary with the serpentine spring stiffness constant, the relative rotation of the two halves of the coupling and the torque passed to a linear relationship, a constant stiffness Grid Couplings. 
 Tooth shape as the curve: the load is small, the linear part of the serpentine spring and join the axis of the basic parallel; the load increases, the deformation of the serpentine spring increase also increases the tooth contact arc, with teeth shorter and shorter distance between the point of contact, the stiffness increases, the relative rotation of the two halves of the coupling torque passed as a non-linear relationship, a variable stiffness Grid Couplings. 
 Linear tooth to facilitate the processing and low cost. Wider application, but only small changes in working conditions in the transmission torque. Tooth curve for working conditions and reversing torque changes, and has good cushioning effect, but the curve toothed process is poor, the relatively high manufacturing costs. 

 Grid Couplings features: 
 A. High performance, excellent cushioning effect, and can completely replace the imported brands. 
 Two. All-metal design, the spring can slow vibration 30% or more in power transmission systems subjected to excessive vibration and shock protection. 
 3. High elasticity, high-precision processing, the passivation of the alloy steel spring, long-lasting corrosion resistance, to ensure product performance. 
 Grid Couplings application: 
 This coupling is a metal flexible coupling, it is widely used in metallurgy, petrochemical, mining, shipbuilding, water pumps, printing machinery and other mechanical drive shafts to transmit torque, enables transmission of shock and vibration, noise is significantly improved. The use of reliable, light weight, large torque.
