High acceleration/deceleration applications create shock loads to system components. If the shock is not absorbed, this can result in excessive vibration and increased settling time, with a resulting loss in machine efficiency and possible component failure and machine downtime. For applications where greater shock absorption is desired, Ruland has expanded its line of zero-backlash shockabsorbing jaw couplings to include more compliant spider elements. The spider provides dampening of impulse-type loads, minimizing shock to the motor and other sensitive equipment. Spider elements of three hardness levels are offered, each represented by a different colour. The blue spiders have a durometer of 85 shore, yellow spiders are 92 shore and red spiders 98 shore. Selecting the soft spider element will give the jaw coupling the greatest dampening characteristic, while a harder spider element will provide the greatest in torsional rigidity. Ruland Manufacturing
