Nylon type coupling is the latest product, has been widely used abroad, NL - type nylon ring gear in drum type coupling half couplings with precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, 45 # steel, axle hole and the keyway USES the drawing forming, inside the nylon coupling elastomer coat could be selected according to user requirements of various hardness synthetic materials such as nylon, enhancing casting nylon elastomer.

Formation and characteristics:

NL nylon type coupling in ordinary nylon jacket in a series of improvements, USES the high strength glass fiber nylon 66 injection molding, injection molding temperature 330 c, 4 s, 9 mpa pressure, time for 1 hour after heat-treatment humidify, 24 hours a day, make its strength is beyond ordinary nylon three times. The product designed by mechanical committee of jinan casting forging machinery research institute, suitable for axial and flexible transmission, allowing the larger axial radial displacement and Angle displacement, and has simple structure, convenient maintenance, easy tear open outfit, low noise, small transmission efficiency loss, long service life, etc.

The basic parameters:

The shaft type has cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are machined in accordance with the national standard gb3852-83 "shaft of the coupling and the form and dimension of the key groove". Working temperature is 20 ~ + 70 ℃. Each form has 10 specifications, and the diameter of the shaft is 6 to 100mm, the length of the shaft is 16 to 212mm, the nominal torque T = 40-3150 n. m, which is 1800-6000r. Min.
