Solitary joint equipment couplings are employed to join two nominally coaxial shafts. In this application the device is referred to as a equipment-variety flexible, or adaptable coupling. The solitary joint permits for small misalignments this kind of as set up errors and alterations in shaft alignment because of to working circumstances. These kinds of gear couplings are generally minimal to angular misalignments of 1/four to 1/2°.

Equipment couplings ordinarily come in two variants, flanged sleeve and ongoing sleeve. Flanged gear couplings consist of brief sleeves surrounded by a perpendicular flange. One particular sleeve is put on each shaft so the two flanges line up face to face. A collection of screws or bolts in the flanges maintain them jointly. Constant sleeve gear couplings feature shaft finishes coupled with each other and abutted against every single other, which are then enveloped by a sleeve. Generally, these sleeves are produced of metal, but they can also be made of Nylon.

Each joint generally is composed of a 1:one equipment ratio internal/external gear pair. The tooth flanks and outer diameter of the exterior gear are topped to permit for angular displacement amongst the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are named gears because of the reasonably large dimensions of the tooth. Gear couplings are generally restricted to angular misalignments of 4 to 5°.
