Introduction Of cast iron NM flexible shaft coupling
Cast iron NM flexible shaft coupling is a cylindrical pin made of some non-metallic materials, which is placed between the two sides of the coupling and the inner surface of the outer ring, and a device to transfer the torque through the column pin to realize the connection between two half couplings. Cast iron NM flexible shaft coupling between the slider made of bakelite cloth or polyurethane, suitable for high speed, large torque, no sharp impact of the two connections. The standard code of the pump industry is Bl104. The maximum allowable torque is 850N m, and the maximum shaft diameter is 50mm.The characteristics of the China Manufactory NM Spider Coupling:1. It is small in size, light in quality, simple in structure, convenient in installation and low in price. It is often used in small power occasions.2, the transmission torque is large, and in the same torque, most of the rotary diameter is smaller than the tooth coupling, and it can partly replace the tooth coupling.3, the inertia force is small, it is suitable for two axis connection with little torque, high speed and no sharp impact. The transmission torque of nylon slider is small, but it is more suitable for high-speed operation without lubrication.
