The cross shaft universal coupling can make the two axes that are not on the same axis or have a large Angle of disconnection or large axial movement rotate continuously at the same angular speed, and reliably transmit torque and movement.

The universal coupling of cross shaft is the most widely used coupling at present. It is worth noting that during the installation process, measurements and adjustments are required to ensure its safety.

One is to use a knife straight ruler and a feeler ruler to measure the deviation of the coupling. This method is suitable for devices with low precision or slow elastic connection speed.

The second is to measure the non-concentricity and non-parallelism of the two couplings with dial indicator and gage frame. This method is suitable for rotary equipment with high speed, rigid connection and high precision.
