NL type nylon inner ring gear drum coupling is the national standard model. Another type of nylon inner ring gear coupling produced by our factory is NL type nylon ring gear drum shaped gear coupling.
1) The inner ring gear of nylon inner ring gear coupling is made of MC nylon material, and the outer tooth sleeve is made of 45 # forged steel. It has small size, light weight, low rotational inertia, low noise, easy assembly and disassembly, no lubrication, etc. Advantages, can be applied to the working environment of small and medium torque, such as fans, water pumps, lubrication pumps, textile machinery, etc.
2) NL-type drum-shaped nylon ring gear coupling has the following three structural types:
A --- Basic type: B --- Inner ring type: C --- Outer ring type
