The importance of SWC universal couplings

Universal couplings are important components that connect the prime mover and the working machine. Their damage will cause the machine to stop and even affect the entire production line. Therefore, the reliability requirements for them are quite high.

Universal couplings are important components that connect the prime mover and the working machine. Their damage will cause the machine to stop and even affect the entire production line. Therefore, the reliability requirements for them are quite high. However, the conditions under which universal couplings operate often have certain limitations, such as: In the drive of rolling mills, due to the certain diameter limitations of the connected rolls, the rotational diameter of the coupling is also correspondingly restricted. The actual torque during the rolling process is often close to the fatigue torque of the coupling. If not handled properly, it may even exceed it. If this overload phenomenon occurs frequently, it will greatly reduce the fatigue life, leading to premature failure or damage.

In addition, the spatial geometric position requirements for universal couplings are also relatively high. If not handled properly, additional torques will occur, which will also reduce their service life and affect their transmission efficiency. For large couplings, due to inadequate maintenance techniques and improper adjustment of the balance system, additional loads equivalent to the torque level or large loads may also occur, and in some cases, even cause the cross shaft to break. Therefore, for such a core device, there should be comprehensive technical control to ensure its lifespan.

Universal couplings have the advantages of large transmission Angle, high efficiency, smooth transmission, low noise, small clearance impact and large transmission torque. Especially under the correct technical control conditions, a very long service life can be achieved. Therefore, it has been increasingly adopted by various machines. For example: At present, the adoption rate of domestic rolling mills has reached about 70%, with a large rotary diameter of 1200mm and a transmission torque of 3200kN.m.
