SWC type cross shaft universal coupling is one of the most commonly used couplings.Utilizing the characteristics of its structure, it can make two shafts that are not on the same axis or that have a large angle of axis or that have a large axial movement continuously rotate at equal angular speed, and reliably transmit torque and motion.Can be widely used in metallurgy, lifting, engineering transportation, mining, petroleum, shipbuilding, coal, rubber, papermaking machinery and other heavy machinery industries to transmit torque in mechanical shafting.
The main features of SWC type and SWP type cross shaft universal coupling are:
1. It has a large angle compensation capability.
2. The structure is compact and reasonable. SWC type adopts integral fork head, which makes the transportation more reliable.
3. Large carrying capacity.Compared with other types of couplings with the same rotating diameter, the torque transmitted by it is larger. This is more advantageous for mechanical equipment with restricted rotating diameter.
4. High transmission efficiency.Its transmission efficiency is 98-99.8%, and it is used for high-power transmission with obvious energy-saving effect.
5. Stable transportation, low noise, easy assembly and disassembly and maintenance.
