The 3102-2201025 Russian universal joint cross is a kind of coupling of mechanical transmission parts. It can be said that the universal joint belongs to the coupling. There are many types of couplings, including plum blossom couplings, account sleeve couplings, elastic couplings, parallel couplings, diaphragm couplings, universal couplings, etc. These couplings are all couplings, but the models are different, and the conditions for selection and use are also different.

Universal joints are also called universal couplings. Universal joints are mostly used in occasions with large torque and poor concentricity of the two shafts. It is easy to confuse the universal joint with the coupling when purchasing.

Universal joint transmission is a transmission method with a middle flexure. Because the transmission belt is elastic and depends on friction for transmission, it has a simple structure, stable transmission, low noise, buffer and vibration absorption, and the transmission belt will slip on the pulley when overloaded. , It has the function of overload protection for other parts, and is suitable for the advantages of large center distance transmission. It is widely used in mechanical transmission, especially the V-belt transmission in driving transmission, which is extremely widely used.

Mechanical transmission is widely used in mechanical engineering, mainly referring to the transmission of mechanical hull power and movement. The mechanical transmission of 5-280X PRECISION 334 universal joint is based on the way of force transmission, mainly chain transmission, gear transmission and belt transmission.
