The NL type nylon inner tooth coupling is suitable for shaft to shaft and flexible rotation, allowing for large axial and radial displacement. It has the advantages of simple structure, easy maintenance, easy disassembly and assembly, low noise, small transmission dynamic loss, and long service life. There are cylindrical, conical, and short cylindrical shaft hole types. The shaft hole and keyway shall be processed according to the provisions of the national standard GB3852-83 "Form and Size of Coupling Shaft Hole and Keyway". The working thermometer is 20~+700 ℃, with a torque range of 40N · m-315N · m
The NL type nylon inner tooth coupling is composed of inner and outer teeth with the same number of teeth. Due to the large gap between the inner and outer teeth, the connected transmission shaft system is allowed to have a large displacement and can withstand a large load. A detailed description of the internal tooth type coupling used for rotational transmission between shafts, allowing for a complete set of shafts and radial displacement. The internal tooth type elastic coupling produced by our factory has many advantages, such as detailed design, simple structure, easy disassembly and assembly, easy operation, simple maintenance, long service life, low noise, low cost, and small loss of individual transmission power. The types of elastic coupling shaft holes are cylindrical (Y) and short cylindrical (J). The coupling keyway is processed according to the national standard GB3852-83 (Coupling shaft hole and keyway type dimensions). The working temperature of the internal toothed coupling is -20 ° C to 70 ° C. The coupling material is made of cast iron HT20-40 finely cast and reinforced injection molded nylon (nylon 66), which has undergone special industrial treatment. The ten series of internal tooth shaped elastic couplings produced by our factory are widely used in the transmission of machinery in industries such as forging, construction, mining, plastics, food, engineering, petroleum, chemical, machine tools, ships, leather, textiles, fans, water pumps, etc. The use of this internal toothed elastic coupling is more effective than other structural couplings
