The NL-type nylon inner gear coupling is a national standard model. Another nylon inner gear coupling produced by our factory is the NL-type nylon inner gear drum gear coupling. NL type nylon inner gear ring coupling has the following three structural types: A--- basic type; B---inner retaining ring type; C---outer retaining ring type. TGL type—Nylon inner gear ring drum gear coupling. The inner gear ring material adopts MC nylon material, and the outer gear shaft sleeve adopts No. 45 forged steel. It has small size, light weight, low moment of inertia, low noise, assembly and disassembly Convenience, no need for lubrication, etc., can be applied to small and medium torque working conditions, such as fans, water pumps, lubrication pumps, textile machinery, etc.
