GEAR COUPLING
Solitary joint gear couplings are used to hook up two nominally coaxial shafts. In this application the device is known as a gear-type flexible, or adaptable coupling. The one joint enables for small misalignments this sort of as installation problems and changes in shaft alignment owing to operating situations. These 
types of gear couplings are generally restricted to angular misalignments of 1/four to 1/2°.
Equipment couplings ordinarily occur in two variants, flanged sleeve and continuous sleeve. Flanged gear couplings consist of quick sleeves surrounded by a perpendicular flange. One particular sleeve is positioned on every shaft so the two flanges line up face to encounter. A collection of screws or bolts in the flanges hold them with each other. Continuous sleeve gear couplings attribute shaft finishes coupled with each other and abutted towards every single other, which are then enveloped by a sleeve. Usually, these sleeves are produced of steel, but they can also be produced of Nylon.
Each joint usually consists of a 1:one equipment ratio interior/exterior equipment pair. The tooth flanks and outer diameter of the exterior equipment are topped to permit for angular displacement among the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are named gears due to the fact of the reasonably massive dimension of the tooth. Gear couplings are generally constrained to angular misalignments of four to 5°.
