NL type drum gear coupling
Summary:NL-type drum gear coupling has been widely used externally. It is a new product in the current industry. It is suitable for flexible transmission between shafts and allows large axial and radial displacement and angular displacement. Drum gear type The coupling is a rigid-flexible coupling, with radial, axial and angular axis deviation compensation capabilities, simple structure, convenient maintenance, easy disassembly and assembly, low noise, low transmission efficiency loss, long service life, etc. advantage.

Drum gear type The coupling is a rigid-flexible coupling, with radial, axial and angular axis deviation compensation capabilities, simple structure, convenient maintenance, easy disassembly and assembly, low noise, low transmission efficiency loss, long service life, etc. Advantages, favored by users.
The NL type drum gear 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.
