In order to meet the needs of the renewal and transformation of various machinery and the introduction of equipment and spare parts, our company can provide a complete range of internal tooth-shaped elastic couplings. Our factory has launched a series of products such as spline holes, tapered holes, and inch holes. Users need to accept non-standard orders.

The inner tooth elastic coupling is currently the latest domestic product and has been widely used abroad. The NL type-nylon inner gear drum gear coupling half coupling adopts precision casting, cast iron HT20-40, cast iron Steel ZG35Ⅱ, No. 45 steel, the shaft hole and keyway are made by drawing, and the inner gear coupling elastomer jacket can be selected from various hardness synthetic nylon, reinforced cast nylon elastomer and other materials according to user requirements. NL inner tooth elastic coupling ordinary nylon jacket has undergone a series of improvements, using high-strength glass fiber nylon 66 injection molding, injection temperature 330C, pressure 9MPA, time 4S, heat treatment for 1 hour and humidification for 24 hours after molding , Its strength exceeds 3 times that of ordinary nylon.This product is designed by the Jinan Foundry and Metalforming Machinery Research Institute of the Machinery Committee. It is suitable for flexible transmission between shafts and allows large axial and radial displacement and angular displacement. It has simple structure, convenient maintenance, easy disassembly and assembly, and low noise. , The advantages of low transmission efficiency loss and long service life are very popular among users.The shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway are processed in accordance with the national standard GB3852-83 "Coupling shaft hole and keyway form and size".The working temperature is -20～+70℃.
