Couplings

In power transmission, couplings are mechanical elements used to connect two drive elements together for the transfer of torque from one element to another. A coupling connects both elements, usually shafts that are in rotational movement, while also allowing a certain degree of misalignment, end movement, or both.

Couplings can be either rigid or flexible. Rigid couplings are more commonly used when two shafts are co-axial or lie on the same axis as each other. Flexible couplings are used where there is less chance of co-axiality or when shocks are likely to occur during transmission of torque.

In industrial machinery, couplings serve the following purposes:

• To connect two shafts of separately manufactured units, for example, a motor and a generator.
• To also allow for disconnection of the shafts for maintenance or repair operations or replacement of parts
• To connect both the driving and the driven part.
• Allow misalignment of the shafts and to reduce shock loads at the meeting point of both shafts

At SLS, we offer a broad variety of both rigid and flexible couplings for a variety of industries and applications:

• Gear Coupling
• Grid Coupling
• Elastomeric Coupling
• Disc Coupling
• Fluid Coupling
• Composite Coupling
• Long Term Grease
