1. It has the advantages of simple structure, convenient maintenance, easy disassembly and assembly, low noise, small loss of transmission efficiency and long service life.
2. The nylon sleeve is injection-molded with high-strength glass fiber nylon 66. The injection temperature is 330C, the pressure is 9MPA, and the time is 4S. After molding, it is heat-treated for 1 hour and humidified for 24 hours to make its strength 3 times higher than that of ordinary nylon.
3. The advantages of nylon sleeves as transmission accessories are non-conductive, shock-resistant, not easy to corrode, low thermal conductivity, non-magnetic, excellent performance, low noise, good anti-loose performance, and long service life.
4. When the torque is too large, the nylon sleeve will be broken by the excessive torque to protect the equipment.
NL nylon drum gear sleeve couplings are mainly used for the transmission of forging, construction, mining, plastics, food, engineering, petroleum, chemical, machine tools, ships, leather, textiles, fans, water pumps and other industries, and can also be used in large-scale on amusement equipment,
It is suitable for flexible transmission between shafts and shafts, allowing large axial and radial displacements and angular displacements, and has the advantages of simple structure, convenient maintenance, easy disassembly, low noise, small loss of transmission efficiency, and long service life， popular with users. NL type nylon inner ring gear drum gear coupling half coupling is made of cast steel or 45# steel. The shaft hole and keyway are drawn, and the elastic body jacket of the inner gear coupling can be selected according to the user's requirements. Synthetic rubber grease rubber with various hardness; reinforced cast nylon elastic body and other materials.
The tooth width coefficient affects the root bending strength and tooth surface contact strength of the gear tooth. The larger the tooth width coefficient is, the greater the two strength values are. The tooth width coefficient affects the degree of coincidence. When the tooth width coefficient is smaller than the value range, the increase of its value has a greater impact on the increase of the coincidence degree, and when it is greater than this value, the increase of its value has little effect on the increase of the coincidence degree. For the drum-shaped tooth coupling with circular arc drum curve, the tooth width is also a parameter to determine the drum radius and backlash. The larger the tooth width, the larger the drum radius, and the greater the required backlash. Therefore, under the condition that the tooth root bending strength and tooth surface contact strength are sufficient, the tooth width should be determined with a large coincidence degree, and the tooth width should not be increased blindly, so as not to increase the structural size. Generally, the tooth width coefficient is used. The tooth width should be determined by the allowable tooth root stress, and the width required for the displacement of the force point along the tooth width caused by the inclination between the shafts should also be considered.
