Nm elastic claw coupling, also known as convex claw coupling. Structurally similar to the elastic plum blossom coupling, it adopts specially designed synthetic rubber, with two similar bodies made of cast iron, rubber coupling nm series It mainly consists of two cast iron (fc25 material) bodies and rubber couplings. The rubber coupling nm series is (fc25) cast iron, with rubber in the middle as the buffer The coupling formed is the connecting part between the pump and the motor, which is often used in general machinery.
1. Economical and practical, quiet and stable operation, easy assembly and maintenance;
2. It can provide high torque and intermittent operation for the equipment;
1. Made of high-grade cast steel;
2. The rubber material is NBR; BBR characteristics: excellent oil resistance, performance and TM; ACM is equivalent to fluororubber.
3. Outer diameter: 50mm, 67mm, 82mm, 97mm, 112mm, 128mm, 148mm, 168mm, 194mm, 214mm;
4. Working temperature: - 40 ~ + 120 degrees.
1. Moderate elasticity, resistance, oil resistance, acid resistance and alkali resistance. Good wear resistance; Heat resistance; Aging resistance and air tightness. Basic acid-base resistance.
2. The polyurethane plastic of nm elastic coupling is an elastic element, which has the advantages of cushioning, shock absorption, wear resistance, easy disassembly and assembly, etc. the working temperature is - 35 ~ + 80 degrees. It can be interchanged with ROTEX coupling of West Germany. The buffer pad of the coupling is limited by convex claws, which can avoid internal deformation due to impact and external deformation due to centrifugal force; The large concave surface of the claw makes the surface pressure on the involute teeth very small. Even if the teeth are overloaded, the teeth will not be worn or deformed.
Nm elastic coupling is widely used in supporting equipment of machinery industry, such as ceramic machinery, chemical machinery, woodworking machinery, plastic machinery, textile machinery, construction machinery, stainless steel machinery, auto parts industry, mechanical transmission, motor equipment, and paper products machinery industry.
