Features of Flexible Structure Pulleys

Since the development of steel wire belt in the 60 s of the 20th century, belt conveyor has come into the age of large capacity and long distance carrying. In order to meet the needs of large capacity carrying, pass through research and test time after time, we change the pulley from rigid structure to flexible structure.
The appearance of rigid structure pulleys and flexible structure pulleys are basically similar. but their inner structure are absolutely different. For flexible structure pulleys, flexibility distortion is allowed in the field of allowable stress to absorb partial kinetic energy, relax local stress concentration, and accordingly enhance the whole fatigue intensity of pulleys and extend life-span.  It can ensure of more than six years of continuous operation.
