Talk about how the cross cardan shaft develops the transmission system

Cardan shaft has a variety of structural forms, such as: cross shaft type, ball cage type, ball fork type, bump type, ball pin type, ball hinge type, ball hinge piston pump type, three pin type, three fork lift type , three-ball pin type, hinge lift type, etc.; the common type is the cross shaft type, followed by the ball cage type. In specific applications, according to the size of the transmitted torque, it is divided into super heavy, medium and small, light and medium.

The cross universal joint shaft uses its organizational characteristics, so that the two shafts do not have the same center line. Under the condition of the center line intersection angle, the connected two shafts will be rotated continuously, and the torque and fitness movement will be transmitted reliably. Its structure has great angular compensation work capacity, compact structure and efficient transmission system. Different structural forms of universal joints have different angles of intersection between the two center lines, generally in the middle of 5°-45°.

The cross universal shaft is composed of 2 single universal ball couplings and connecting shafts, which can be used to complete the connection of two helical gears that overlap, parallel planes or indoor spaces, to complete the connection between the pinion and the driven shaft. Transmission of the driving force of fitness movement. It plays a key role in the development trend of machine automation and vehicle industrial production. In order to adapt to different working conditions, the connecting shaft is generally divided into two parts, left and right, and is connected by a spline shaft. The mutual parts of the two sides of the fork surface can be adjusted by changing the installation relationship of the spline shaft. The design scheme of the cross-axis transmission system can transmit the driving force, reduce the vibration caused by the transmission of the fitness exercise, and try to maintain the uniform rotation of the two axes and transmit the same torque.
