[0002] A constant velocity joint (CVJ) is a mechanical component used to transmit rotational power. It typically consists of internal and external splines, which can be connected to other parts to transmit torque and allow rotation at various angles. This design allows equipment or vehicles to maintain a constant speed at the drive wheels when cornering, while reducing vibration and power loss.

[0003] After the constant velocity joint is produced, the position and deviation of the external spline need to be measured. However, the external spline is set around the outer wall of the constant velocity joint.
