Use Expansion Sleeves To Compensate For The Deflection Of The Two Axes Of The Universal Joints

When the cardan type universal joint rotates, the stress caused by the angular offset acts as alternating stress, and the tooth side space is larger than that of ordinary gears. The universal cardan shaft compensates for the relative offset of the two axes and has vibration reduction and buffering functions.

Universal joints and driveshafts are used to connect two shafts in different structures. In high-speed and heavy-load power transmission, some expansion sleeves also play the role of buffering U-joints and driveshaft vibration and improving the dynamic performance of the shaft system. When the instantaneous speed of the two shafts is the same, the two shafts are deflected or there is relative displacement during operation, an expansion sleeve can be used on the universal cardan shaft. According to the compensation displacement, it can be divided into rigid movable expansion sleeve and elastic movable expansion sleeve. The rigid movable expansion sleeve uses the dynamic connection between the working parts of the expansion sleeve, and has a certain direction or several directions. To compensate for the deflection and displacement of the two axes, the elastic movable expansion sleeve uses the elastic deformation of the elastic element to compensate for the deflection and displacement of the two axes. The elastic element also has buffering and vibration-damping functions.
