universalcouplingIt's a special kind of thingcoupling, divided into precision universal jointscouplingAnd high torque universal jointcouplingTwo major categories, used for movable rigidity on two-phase intersecting axescouplingThe maximum angle between the two axes can reach 45 °, and it is widely used in machine tools, automobiles, precision machinery, and heavy machinery. universalcouplingComposed of two fork shaped components and one cross shaped component connected together. When the driving shaft rotates at an equal angular velocity ω 1, if the angle between the two axes is α, the angular velocity ω 2 of the driven shaft will undergo periodic changes within the range of ω 1cos α ≤ ω 2 ≤ ω 1/cos α, thereby causing additional dynamic loads. Therefore, a single universal jointcouplingNot suitable for connections with high rotational speed and large angle between two axes. To overcome the above drawbacks, a dual joint universal joint can be usedcouplingConnect two universal joints with one intermediate shaftcouplingWhen installing, make the angle between the axis of the main and driven shafts and the intermediate shaft equal, and make the fork shaped parts at both ends in the same plane, so that the angular velocity of the main shaft and the driven shaft is always equal. Utilizing cage style universal jointcouplingThe ball groove universal joint can also make the instantaneous velocities of the two shafts approximately equal. SWC type, SWP type cross axis universal jointcouplingCan be widely used in metallurgy, lifting, engineering transportation, mining, petroleum, ships, coal, rubber, papermaking
