The gear coupling is composed of an inner gear ring and an outer tooth with the same number of teeth. Due to the large gap between the inner tooth and the outer tooth, the coupled coupling transmission shaft system is allowed to have a larger displacement and can bear a larger load. .Detailed description TGL drum gear couplings are mainly used in small and medium torque industrial and mining environments, such as fans, water pumps, oil pumps, lubrication pumps, textile machinery, printing and dyeing machinery, etc. Nylon inner gear couplings and their inner gear materials Using MC nylon material, the outer gear shaft sleeve is made of No. 45 forged steel, which has the advantages of small size, light weight, low moment of inertia, low noise, easy assembly and disassembly, and no lubrication.Structural features:
