Roller couplings, also known as roller-type couplings or shaft couplings, are mechanical devices used to connect two rotating shafts. They are designed to transmit torque from one shaft to another while accommodating certain misalignments. The core principle of a roller coupling involves the use of rollers that are free to move within a designated space, allowing for the transmission of power even when the shafts are not perfectly aligned.

There are several designs of roller couplings. A common type features two hubs, each with a set of gear teeth or splines. These hubs are enclosed within a housing that contains rollers. The teeth on the hubs mesh with the rollers, and the rollers, in turn, transmit the rotational force. The flexibility of the rollers allows them to adjust their position as the shafts move, compensating for angular, parallel, or a combination of both misalignments.

Roller couplings are valued for their ability to handle significant misalignments compared to some other coupling types. They are also known for their robustness and ability to transmit high torque. Applications for roller couplings can be found in various industrial machinery, including pumps, conveyors, mixers, and in some automotive or marine propulsion systems where shaft alignment can be challenging. Their design often contributes to reduced vibration and noise transmission. Maintenance typically involves ensuring proper lubrication of the rollers and housing.
