Introduction to the structural characteristics of universal couplings and their fixing methods
The 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.Its biggest feature is its strong ability to compensate displacement in all directions, compact structure, high transmission efficiency, and easy maintenance.It is widely used in metallurgical machinery, petroleum machinery, papermaking machinery, engineering machinery, lifting and transporting machinery and other heavy machinery, etc.
universalCouplingCommon types are: general-purpose, high-speed, miniature, retractable, high-torque universal couplings and many other types.WS.WSDSmall cross shaft universal coupling Suitable for connecting the axis angle of the two shafts β≤45° drive shaft system; transfer nominal torque11.2~1120N·m Single cross shaft universal coupling and double cross shaft universal coupling.Universal couplings are widely used in various general mechanical occasions due to their large deviation angle and high transmission torque.
(two)If the appropriate coupling balance level cannot be obtained from the machine manufacturer, it can be used as a reference guide for general users. The universal coupling is suitable for the angle between the axis of the two shafts on the same plane of the connection space β≤45oTransmission occasions,Transfer nominal torque11.2-1120N.m.WSDThe type is a single cross universal coupling,WSType is double cross universal joint with the maximum included angle between each section of the shaft45o.Finished holeH7, According to requirements, keyway, hexagonal hole and square hole can be opened.Allow the angle between the two shafts to change within a limited range as the work needs.
(three)Whether the unbalanced amount of the coupling can meet the needs of any type of rotating system depends on the performance of each particular connected machine, and it is best to be determined by the manufacturer of the connected machine.
