The main purpose of the nylon ring within the coupling is: forging, construction, mining, plastics, food, construction, oil, chemicals, machine tools, shipbuilding, leather, textiles, fans, pumps and other mechanical transmission parts industry. The inner tooth elastic sleeve is better than using elastomer other structures. The nylon ring inside the main material: Nylon PA6, reinforced nylon PA66, its main distinguishing feature is: increase in the nylon ring inside the reinforced nylon cord, wear-resistant high-temperature materials added to enhance coagulation rubber, wear-resistant and durable high temperature, than within the general coupling nylon ring mounted on the coupling run smoother, better, reinforced nylon ring inside my nylon products factory has applied for national patent, generic within the factory production of reinforced nylon tooth sets are fake and shoddy products. Nylon inner ring is currently the fastest replacement products in foreign countries has been widely adopted for inter and flexible drive shaft with nylon gear coupling with the permit large axial and radial displacement angular displacement, and has a simple structure, easy maintenance, easy disassembly, low noise, small transmission loss efficacy, long life and other advantages, much users. I plant the production of nylon gear sleeve wear and durable, high temperature, the working temperature of -20 ~ + 70 ℃.
