What is the cardan shaft used for? The cardan axis principle

Now with the development of society, I believe many friends of some mechanical equipment are not very understanding! Today we will give you popular science cardan axis! What exactly is the cardan shaft used for? Where is it usually used?

1, cardan axis characteristics

Universal coupling has a variety of structural types, such as: cross shaft type, ball cage type, ball fork type, lug type, ball pin type, ball hinge type, ball hinge plunger type, three-pin type, three-fork rod type, three-ball pin type, hinge rod type. The most common type is the spider, followed by the ball cage. The common feature of universal coupling is that the Angle compensation is large. The Angle between the two axes of the universal coupling of different structural types is different, generally ≤5-45°. The universal coupling uses the characteristics of its mechanism, so that the two axes are not on the same axis, when there is an Angle between the two axes, it can realize the continuous rotation of the connected two axes, and reliably transmit torque and movement. Universal coupling has the characteristics of large Angle compensation capacity, compact structure and high transmission efficiency. In practical applications, it is divided into heavy, medium, light and small according to the torque transmitted.

2. Cardan axis function

Function: cushioning, damping and improving dynamic performance of shafting

The universal coupling uses the characteristics of its mechanism, so that the two axes are not on the same axis, when there is an Angle between the two axes, it can realize the continuous rotation of the connected two axes, and reliably transmit torque and movement. The main characteristics of the universal coupling are: its structure Angle compensation capacity is large, compact structure, high transmission efficiency. The Angle between the two axes of the universal coupling of different construction types is different, usually between 5° and 45°.

3. Application scenario of cardan shaft

A universal coupling is a mechanical component that connects two rotating axes and transmits torque or rotation Angle. Universal coupling is widely used in general machinery, hydraulic machinery, engineering machinery, metallurgical machinery, mining machinery, chemical machinery and other occasions!
