Solitary joint gear couplings are used to connect two nominally coaxial shafts. In this application the device is known as a equipment-variety adaptable, or versatile coupling. The one joint makes it possible for for minor misalignments such as installation errors and adjustments in shaft alignment thanks to running circumstances. These types of gear couplings are usually limited to angular misalignments of 1/4 to 1/2°.

Equipment couplings ordinarily occur in two variations, flanged sleeve and constant sleeve. Flanged equipment couplings consist of short sleeves surrounded by a perpendicular flange. 1 sleeve is put on every single shaft so the two flanges line up confront to encounter. A collection of screws or bolts in the flanges maintain them with each other. Ongoing sleeve equipment couplings attribute shaft finishes coupled collectively and abutted against each and every other, which are then enveloped by a sleeve. Normally, these sleeves are manufactured of metal, but they can also be made of Nylon.

Each and every joint usually is composed of a one:1 equipment ratio internal/external gear pair. The tooth flanks and outer diameter of the external gear are topped to allow for angular displacement between the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are referred to as gears simply because of the reasonably big measurement of the teeth. Gear couplings are usually limited to angular misalignments of four to 5°.
