The cross shaft universal coupling is the most commonly used coupling.In my country, the cross-shaft universal coupling standard is divided into SWP type (split bearing housing), SWl type (integral fork head), SWZ type (integral bearing housing), etc. according to the bearing fixing method.Each structural feature has its own strengths.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.Its biggest feature is its strong ability to compensate displacement in all directions, compact structure, high transmission efficiency, and convenient maintenance.It is widely used in metallurgical machinery, petroleum machinery, papermaking machinery, engineering machinery, lifting and transporting machinery and other heavy machinery, etc.
