AGMA 9003-C17 PDF

This standard presents information on design, dimensions, tolerances, inspection, mounting, removal, and equipment that is in common use with keyless tapered and keyless straight (cylindrical) bore hubs for flexible couplings. Calculated hub stress values and hub to shaft torque capacities are nominal values. This standard does not present a rigorous analysis of the components.

Applicability

This Standard applies only to hubs and solid shafts made of steel, which generally have material properties of modulus of elasticity equal to 30 × 106 lb/in2, density equal to 0.283 lb/in3, and thermal expansion coefficient equal to 6.36 × 10-6 in/in/°F.

Exclusions

This standard does not apply to couplings attached to shafts with keyways, splines, split hubs or polygon bores.
