Information summary: The coupling and the shaft generally adopt a transition fit, which may cause a small amount of interference or a small amount of clearance. For couplings with longer hubs, a looser transition fit can be used because the shaft hole is relatively small. Long, due to the rough and uneven surface processing, there will naturally be some interference after assembly. When the coupling manufacturer removes the coupling, it is not allowed to hit it directly with a hammer but should be padded with a copper rod.

The coupling and the shaft generally use a transition fit, which may cause a small amount of interference or a small amount of clearance. A looser transition fit can be used for couplings with longer hubs because the shaft hole is longer. The surface is rough and uneven, and will naturally produce some interference after assembly. When the coupling manufacturer removes the coupling, it should not be hit directly with a hammer but should be padded with a copper rod.

Hit the coupling hub rather than the outer edge of the coupling, as this is easily damaged. When knocking on the end face of the shaft hole, it is easy to cause the shaft hole to shrink, so that the shaft cannot pass through; knocking on the outer edge of the counter wheel will easily destroy the flatness of the end face, which will affect the accuracy of the measurement when using a feeler gauge to adjust it later. For couplings with large interference, they should be heated before installation.

The joints with the power input end are connected to the upper and lower ends of the main connecting shaft respectively. At the joints where the two joints are connected to the upper and lower ends of the main connecting shaft, both joints are hub structures with splined tooth slots. The main connecting shaft The upper and lower ends of the main connecting shaft are spline shaft structures with key teeth. The key teeth at the upper and lower ends of the main connecting shaft have drum-shaped tooth tops, tooth sides and tooth roots. The key teeth at the upper and lower ends of the main connecting shaft are respectively inserted into the matching Within the spline grooves of the two joints.

For a straight shaft, place the key into the keyway on the shaft. The end of the key should not protrude or recess into the end of the shaft. It is better to be flush. Place the installation plate in the oil tank to heat it. After heating and insulation, pay attention to the position mark quickly. When installed on the shaft, the installation plate and the shaft end should be flush. Before installation, you should carefully check the inner hole of the installation plate and the outer diameter of the shaft to ensure that the surface is clean and free of burrs.
