Flange Universal Shaft Coupling
A flange universal shaft coupling is a special transmission device that achieves power transmission between different axes through flange connection. Compared to traditional universal shafts, the flange design provides a more stable connection and higher torque transmission capacity. This transmission device can smoothly transmit rotational motion and torque in the presence of a certain angle deviation from the axis, and is widely used in various industrial equipment and mechanical systems.
The characteristic of flange connection lies in its standardized interface, which is usually fixed with bolts for easy installation and disassembly. The design of the flange not only enhances the rigidity of the connection, but also effectively prevents axial displacement, ensuring the stability of the transmission system. Modern flange universal shafts are usually composed of core components such as cross shafts, bearing seats, and flanges. They are made of high-quality alloy steel and undergo precision machining and heat treatment to ensure their durability and reliability.
In terms of torque transmission efficiency, the flange universal shaft coupling performs well. Its transmission efficiency can generally reach over 98%, far higher than other types of flexible couplings. High efficiency means less energy loss, which is particularly important for modern industries that pursue energy conservation and environmental protection. In addition, the flange type universal shaft coupling also has excellent overload protection function. When the system experiences abnormal loads, it can absorb the impact to a certain extent, protecting the driving and driven equipment from damage.
Another important feature is its ease of maintenance. Most flange type universal shaft couplings adopt modular design, and the components can be replaced separately, greatly reducing maintenance costs. The lubrication system has also been optimized and designed, with some models adopting lifetime lubrication or extended lubrication cycle design, reducing daily maintenance workload.
Typical application areas of flange universal shaft coupling
Construction machinery industry: In equipment such as excavators and loaders, flange type cardan shaft couplings connect the engine and hydraulic pump to adapt to various angle changes during equipment operation.
Steel metallurgy equipment: used for heavy equipment such as rolling mills and continuous casting machines, capable of withstanding high torque and impact loads, and maintaining stable operation in harsh environments.
Ship propulsion system: Connect the main engine to the propeller shaft, compensate for ship deformation and installation errors, and ensure reliable power transmission.
Wind power equipment: In wind turbines, the gearbox is connected to the generator to adapt to the axis deviation caused by tower oscillation.
Petroleum drilling and production equipment: used for the top drive system of drilling rigs, capable of withstanding high torque and vibration under extreme working conditions.
