Double Diaphragm Couplings

Goyal Engineering Company offers Unique brand Double Diaphragm Couplings. These couplings use highly flexible diaphragms. They consist of rubber reinforced with nylon chords. Further at inner and outer bolting PCD steel ring reinforcements are used. Torque ratings are determined after extensive tests and have large service factor against rupture. Rupture torque is typically 6 to 10 times rated torque. At nominal torque torsional angle is large – typically 10 to 15 degrees. Torsional stiffness is low. This results in low critical speeds, usually below operating speed. Further torsional stiffness varies with load. At lower loads stiffness is lower. This feature allows operation at wide range of speeds. Favourable damping characteristics ensure vibration amplitude is limited at resonance. Founded in 1986, the company has over 20 years of experience in the design and manufacture of Unique brand flexible couplings, in all range with reliable, quality products engineered for the cost effective. The manufactured range includes: flexible couplings, tyre couplings, pin bush couplings, diaphragm couplings, star couplings, spare rubber products and all types of mountings. The company manufactures all types of couplings in the finest forms, which are absolutely apt for plant, and cement industries and in many other types of machinery and plants.
