Single joint gear couplings are employed to connect two nominally coaxial shafts. In this software the gadget is known as a equipment-variety flexible, or versatile coupling. The single joint enables for minimal misalignments these kinds of as installation mistakes and changes in shaft alignment because of to running situations. These varieties of gear couplings are usually restricted to angular misalignments of 1/4 to one/2°.

Gear couplings ordinarily occur in two variants, flanged sleeve and ongoing sleeve. Flanged equipment couplings consist of short sleeves surrounded by a perpendicular flange. One particular sleeve is positioned on every single shaft so the two flanges line up encounter to confront. A sequence of screws or bolts in the flanges keep them jointly. Continuous sleeve equipment couplings function shaft finishes coupled with each other and abutted against every single other, which are then enveloped by a sleeve. Normally, these sleeves are produced of metallic, but they can also be manufactured of Nylon.

Each and every joint normally is composed of a one:one gear ratio inside/exterior gear pair. The tooth flanks and outer diameter of the external equipment are crowned to permit for angular displacement among the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are referred to as gears simply because of the fairly massive measurement of the enamel. Equipment couplings are normally minimal to angular misalignments of 4 to 5°.
