Common forms of couplings

Rigid Couplings: Simple and Reliable Connection Method

Rigid couplings are simple connection devices, mainly used in applications where two shafts must be precisely aligned. They are characterized by high torque transmission and compact structure, but require high shaft installation accuracy. Common rigid couplings include sleeve couplings and flange couplings. These couplings are suitable for applications with low speeds and stable loads, such as small mechanical equipment or stationary transmission systems.

Flexible Couplings: Flexible Choice for Misalignment

Flexible couplings can compensate for relative displacement between two shafts, including axial, radial, and angular misalignment. These couplings are further divided into metallic elastic element couplings and non-metallic elastic element couplings. Metallic elastic element couplings, such as gear couplings, are suitable for heavy-duty applications; non-metallic elastic element couplings, such as rubber couplings, are more suitable for environments requiring vibration reduction and noise reduction. Flexible couplings are widely used in automobiles, ships, and industrial equipment.

Safety Couplings: The Last Line of Defense for Your System
A safety coupling is a special type of coupling that automatically disconnects when the transmitted torque exceeds a set value, thus protecting the transmission system from damage. These couplings are commonly used in applications requiring overload protection, such as precision instruments or valuable equipment. Safety couplings come in various designs, including shear pin type, friction type, and magnetic type, allowing users to choose the appropriate type based on their specific needs.
