Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. The resulting fault if alignment is not achieved within the demanded specifications is shaft misalignment , which may be offset or angular.
The shipbuilder must provide a foundation that is sufficiently strong and rigid so that the gear mounting surface does not deflect greatly under operating conditions, a shaft alignment drawing that details the positions of line bearing and the method for aligning the forward piece of line shafting to the reduction gear coupling and the location ...
A grid coupling is composed of two shaft hubs, a metallic grid spring, and a split cover kit. Torque is transmitted between the two coupling shaft hubs through the metallic grid spring element. Like metallic gear and disc couplings, grid couplings have a high torque density. A benefit of grid couplings, over either gear or disc couplings, is ...
Like other flexible couplings, jaw couplings are limited in the shaft misalignment that they can accommodate. Too much axial motion will cause the couplings to come apart, while too much angular or parallel misalignment will result in bearing loads that may lead to premature system wear or failure.
A Rzeppa-type CV joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
A Delta engine has three (or its multiple) cylinders having opposing pistons, aligned in three separate planes or 'banks', so that they appear to be in a Δ when viewed along the axis of the main-shaft. An example of this type of layout is the Napier Deltic.
A driveshaft coupling. Note the split damage beginning to appear, likely due to the large axial displacement. A giubo. A giubo (/ ˈ dʒ uː b oʊ / JOO-boh; etymology: giunto Boschi, "Boschi joint"), also known as a 'flexdisc', and sometimes misspelled as guibo, is a flexible coupling used to transmit rotational torque between the drive shaft and the companion flange on mechanical devices ...
