Zero backlash jaw couplings

Zero backlash jaw couplings Ruland Manufacturing has expanded its line of zero-backlash jaw couplings to include more compliant spider elements for applications where greater shock absorption is desired. Zero-backlash jaw couplings are three-piece couplings comprising two hubs with curved jaws and an elastic element. The spider, made of an advanced polyurethane material, provides dampening of impulse type loads, minimising shock to the motor and other sensitive equipment. As a result of this addition, spider elements of three different hardness levels are offered with each represented by a different colour. The new blue spiders have a durometer of 85 shore, yellow spiders are 92 shore, and red spiders 98 shore. The availability of spiders with three hardness levels allows the end user to customise the jaw couplings performance. Selecting the new soft spider element will give the jaw coupling the greatest dampening characteristic, while a harder spider element will provide the greatest in torsional rigidity. All spiders are press fit onto a curved jaw profile; generous chamfers on the spiders and jawed hubs make this assembly easy. Because of this press fit, Ruland jaw couplings operate with zero backlash.
