What are the differences between constant velocity (CV) and non-constant velocity PTO shaft u-joints?

Constant velocity (CV) and non-constant velocity PTO shaft u-joints are designed to address specific challenges related to angular misalignment and speed fluctuations in power transmission systems. Here are the key differences between these two types:
Angular Velocity:
Constant Velocity (CV): CV joints are designed to maintain a constant speed and transmit power smoothly even when the shaft is at an angle. They are especially useful in applications where there are frequent changes in the angle of the shaft.
Non-constant Velocity: These joints may exhibit variations in speed during rotation. They are not specifically engineered to maintain constant velocity when the angle of the shaft changes.
Angular Misalignment:
Constant Velocity (CV): CV joints are better at accommodating angular misalignment. They allow for smooth power transmission even when the shaft is not perfectly aligned.
Non-constant Velocity: These joints may experience higher levels of vibration and wear when the shaft is misaligned, making them less suitable for applications with frequent misalignment.
Applications:
Constant Velocity (CV): CV joints are commonly used in applications where a smooth and constant speed is crucial, such as in automotive drive shafts and certain agricultural machinery.
Non-constant Velocity: These joints are used in applications where maintaining a constant speed is not as critical, and cost-effectiveness is a priority.
Construction:
Constant Velocity (CV): CV joints typically have more complex designs, often incorporating ball bearings and other mechanisms to maintain smooth and constant velocity.
Non-constant Velocity: Non-constant velocity joints may have a simpler design, making them more cost-effective but less suitable for applications requiring constant speed.
Vibration and Wear:
Constant Velocity (CV): CV joints generally produce less vibration and experience lower wear, especially in applications with variable shaft angles.
Non-constant Velocity: These PTO shaft u-joints may experience increased vibration and wear, particularly when the shaft is misaligned.
