The designof this element determines the character of thecoupling in terms of reaction forces, dynamics andreliabil

32、ity. For this standard, common flexibleelement types have been grouped into three majorcategories which are defined below. Note that thecharacter of a particular flexible element type maycross or fall outside the definitions below. Also notethe properties of flexible elements themselves arenot cover

33、ed in this standard. The reader is directedto the appropriate coupling manufacturers for infor-mation on the properties of a particular type offlexible element.4.2.1.1 Mechanical elementA form of flexible element which accommodatesmisalignment by sliding or rolling on matingsurfaces. These parts nor

34、mally require lubrication.These elements do not have a free state position.They can be at rest at any combination of axial andangular positions within their flexible capability.Mechanical elements resist change in axial andangular position mainly as a function of shaft torqueand coefficient of frict

Examples of mechanical elements are gear,grid and chain.4.2.1.2 Metallic elementA form of flexible element which accommodatesmisalignment by material deflection of a metalmember. Theseelementsareverymuchlikespringsin that they have a free form shape and will resist

Examples ofmetallic elements are contoured diaphragm,convoluted diaphragm, disc, springs and bellows.4.2.1.3 Elastomeric flexible elementTheseflexibleelementsarecharacterizedbytheuseofanelastomer.

Reac-tion forces of elastomeric flexible elements aredetermined by element configuration, material stiff-ness, coefficient of friction and torque. They ca

Because of the greatvariety of designs, some actually fit both categoriesin varying degrees.4.2.1.4 OthersThere are other types of flexible elements thataccommodate misalignm

Elastomericflexible elements and pin and bushing designs canANSI/AGMA 9009-D02AMERICAN NATIONAL STANDARD3accept both parallel and angular misalignm
