Products Features
The material of flange coupling can be gray cast iron or carbon steel. Cast steel or forged steel shall be used when heavy load or circumferential speed is greater than 30m / s. German Lingsi flange coupling has high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, it will cause additional load in the parts and worsen the working condition, which is its main disadvantage. However, due to its simple structure, low cost and large torque transmission, it is often used when the speed is low, there is no impact, the rigidity of the shaft is large and the neutrality is good.
■ Simple and convenient assembly and disassembly;
■ No keyway and thrust ring are required on the shaft;
■ The stress on the entire contact surface is relatively uniform, and the stress concentration is not obvious;
■ When the vibration load of the shaft system changes, the shaft will not be worn;
■ The position of the coupling on the shaft is easy to ensure, and the connection accuracy is high;
■ Can be used repeatedly, with high interchangeability
