Universal joint working principle

Universal transmission device is used to transfer power between two shafts whose relative position changes continuously during the working process. Its function is to connect the transmission output shaft and the main reducer input shaft not in the same straight line, and ensure that the Angle and distance between the two shafts often change, still can reliably transfer power.

The installation precautions of the drive shaft are as follows:

1. The two cross universal joint forks at both ends of the transmission shaft are in the same plane to ensure its constant speed transmission;

2. The telescopic joint should be installed near the transmission or actuator end, which can reduce the runout of the telescopic joint, thus reducing the wear of the telescopic joint: at the same time increase the ground height of the telescopic joint;

3. Pay attention to alignment balance mark, all parts are installed in situ;

4. The refueling nozzle of each transmission shaft should be in the same line, and the refueling nozzle of the universal joint cross shaft should be oriented to the side of the transmission shaft to provide convenience for lubrication;

5. The lock of the two clamps of the dust jacket on the telescopic joint of the transmission shaft should be installed in the radial relative position of 1800.

Universal coupling features:

Its structure has a larger angular compensation capacity, compact structure, high transmission efficiency. Different structure type universal coupling two axis Angle is not the same, generally between 5°-45°.

Universal shaft use: 

used to connect two shafts in different institutions (drive shaft and driven shaft), so that they rotate together, to transfer torque mechanical parts. In high speed and heavy load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of shafting. The coupling consists of two halves connected with the driving shaft and the driven shaft respectively. General power machines are usually connected with working machines by means of couplings.
