Products instruction:

Basic requirements for elastic coupling performance: 1. Large bearing capacity and sufficient strength. The maximum allowable torque of the coupling is required to be more than 3 times the rated torque. 2 It has a strong compensation (radial, angular, axial) effect, and the smaller the reaction force generated during the deviation compensation, the better. 3 It has high elasticity and high flexibility, which can reduce the amplitude of shock and vibration to the allowable range, and should have the function of slowing vibration and shock in the direction of rotation. 4. Reliable work and stable performance. Couplings requiring rubber elastic elements should also have good heat resistance, not easy to age, and have a long service life. 5. The coupling must have an insulation resistance of more than 100 ohms and can withstand a voltage of 2kV. 6Easy to install, maintain and replace.
