A circular key is a cylindrical connecting element that is usually installed in a shaft hole and fits with the circumference of the shaft. The circular key mainly transmits force and prevents relative axial movement through axial load.
Working principle: The circular key mainly transmits force and prevents relative axial movement through axial load. Usually installed in the shaft hole, it is used to connect components that need to withstand axial loads or achieve relative motion.
Advantages of circular keys:
Uniform transmission of force: The circular key transmits force through axial load, which is uniform and less prone to stress concentration.
Prevent axial relative movement: The circular key mainly prevents axial relative movement through axial load, and has good positioning effect.
Flexible installation position: The circular key is usually installed in the shaft hole and is suitable for components that require axial movement.
Disadvantages of circular keys:
Weak torque tolerance: Compared to flat keys, circular keys have weaker torque transmission ability.
Installation is relatively complex: The installation of circular keys is relatively complex and requires accurate installation in the shaft hole, requiring high installation accuracy.
Limited force direction: The circular key mainly transmits force through axial load, and the force direction is relatively limited, which is not suitable for lateral force situations.
